                             INFORMATICA CORPORATION

                                  -------------

                                 PROXY STATEMENT
                                      FOR
                       2002 ANNUAL MEETING OF STOCKHOLDERS

                                  -------------

                               PROCEDURAL MATTERS


General

     This Proxy Statement is being furnished to holders of common stock, par
value $0.001 per share (the "Common Stock"), of Informatica Corporation, a
Delaware corporation ("Informatica" or the "Company"), in connection with the
solicitation of proxies by the Board of Directors of Informatica for use at the
Annual Meeting of Stockholders (the "Annual Meeting") to be held on Tuesday,
May 28, 2002 at 3:00 p.m., local time, and at any adjournment or postponement
thereof for the purpose of considering and acting upon the matters set forth
herein. The Annual Meeting will be held at Informatica's corporate offices,
located at 2100 Seaport Boulevard, Redwood City, CA 94063. The telephone number
at that location is (650) 385-5000.

     This Proxy Statement, the accompanying form of proxy card and the
Company's Annual Report to Stockholders are first being mailed on or about
April 16, 2002 to all stockholders entitled to vote at the Annual Meeting.


Stockholders Entitled to Vote; Record Date

     Only holders of record of Informatica's Common Stock at the close of
business on April 5, 2002 (the "Record Date") are entitled to notice of and to
vote at the Annual Meeting. Such stockholders are entitled to cast one vote for
each share of Common Stock held as of the Record Date on all matters properly
submitted for the vote of stockholders at the Annual Meeting. As of the record
date, there were 79,253,282 shares of Common Stock outstanding and entitled to
vote at the Annual Meeting. No shares of preferred stock were outstanding. For
information regarding security ownership by management and by the beneficial
owners of more than 5% of Informatica's Common Stock, see "Share Ownership by
Principal Stockholders and Management."


Quorum; Required Vote

     The presence of the holders of a majority of the shares of Common Stock
entitled to vote generally at the Annual Meeting is necessary to constitute a
quorum at the Annual Meeting. Such stockholders are counted as present at the
meeting if they (1) are present in person at the Annual Meeting or (2) have
properly submitted a proxy card or voted by telephone or by using the Internet.
A plurality of the votes duly cast is required for the election of directors.
The affirmative vote of a majority of the votes duly cast is required to ratify
the appointment of auditors.

     Under the General Corporation Law of the State of Delaware, an abstaining
vote and a broker "non-vote" are counted as present and entitled to vote and
are, therefore, included for purposes of determining whether a quorum is
present at the Annual Meeting; however, broker "non-votes" are not deemed to be
"votes cast." As a result, broker "non-votes" are not included in the
tabulation of the voting results on the election of directors or issues
requiring approval of a majority of the votes cast and, therefore, do not have
the effect of votes in opposition in such tabulations. A broker "non-vote"
occurs when a nominee holding shares for a beneficial owner does not vote on a
particular proposal because the nominee does not have discretionary voting
power with respect to that item and has not received instructions from the
beneficial owner.




Voting

     Voting by attending the meeting. A stockholder may vote his or her shares
in person at the Annual Meeting. A stockholder planning to attend the Annual
Meeting should bring proof of identification for entrance to the Annual
Meeting.

     Voting by proxy card. All shares entitled to vote and represented by
properly executed proxy cards received prior to the Annual Meeting, and not
revoked, will be voted at the Annual Meeting in accordance with the
instructions indicated on those proxy cards. If no instructions are indicated
on a properly executed proxy card, the shares represented by that proxy card
will be voted as recommended by the Board of Directors. If any other matters
are properly presented for consideration at the Annual Meeting, including,
among other things, consideration of a motion to adjourn the Annual Meeting to
another time or place (including, without limitation, for the purpose of
soliciting additional proxies), the persons named in the enclosed proxy card
and acting thereunder will have discretion to vote on those matters in
accordance with their best judgment. The Company does not currently anticipate
that any other matters will be raised at the Annual Meeting. Any proxy card
given pursuant to this solicitation may be revoked by the person giving it at
any time before it is voted. A proxy card may be revoked (1) by filing with the
Secretary of the Company, at or before the taking of the vote at the Annual
Meeting, a written notice of revocation or a duly executed proxy card, in
either case dated later than the prior proxy card relating to the same shares,
or (2) by attending the Annual Meeting and voting in person (although
attendance at the Annual Meeting will not of itself revoke a proxy). Any
written notice of revocation or subsequent proxy card must be received by the
Secretary of the Company prior to the taking of the vote at the Annual Meeting.
Such written notice of revocation or subsequent proxy card should be hand
delivered to the Secretary of the Company or should be sent so as to be
delivered to Informatica Corporation, 2100 Seaport Boulevard, Redwood City, CA
94063, Attention: Corporate Secretary.

     Voting by telephone or the Internet. A stockholder may vote his or her
shares by calling the toll-free number indicated on the enclosed proxy card and
following the recorded instructions or by accessing the website indicated on
the enclosed proxy card and following the instructions provided.

     When a stockholder votes via the Internet or by telephone, his or her vote
is recorded immediately. Informatica encourages its stockholders to vote using
these methods whenever possible. If a stockholder attends the Annual Meeting,
he or she may also submit his or her vote in person, and any previous votes
that were submitted by the stockholder, whether by Internet, telephone or mail,
will be superseded by the vote that such stockholder casts at the Annual
Meeting.


Expenses of Solicitation

     Informatica will bear all expenses of this solicitation, including the
cost of preparing and mailing this proxy material. The Company may reimburse
brokerage firms, custodians, nominees, fiduciaries and other persons
representing beneficial owners of Common Stock for their reasonable expenses in
forwarding solicitation material to such beneficial owners. Directors, officers
and employees of the Company may also solicit proxies in person or by
telephone, letter, e-mail, telegram, facsimile or other means of communication.
Such directors, officers and employees will not be additionally compensated,
but they may be reimbursed for reasonable out-of-pocket expenses in connection
with such solicitation. The Company may engage the services of a professional
proxy solicitation firm to aid in the solicitation of proxies from certain
brokers, bank nominees and other institutional owners. The Company's costs for
such services, if retained, will not be material.


Procedure for Submitting Stockholder Proposals

     Requirements for stockholder proposals to be considered for inclusion in
the Company's proxy materials. Stockholders may present proper proposals for
inclusion in the Company's proxy statement and for consideration at the next
annual meeting of its stockholders by submitting their proposals in writing to
the Secretary of the Company in a timely manner. In order to be included in the
Company's proxy materials for the 2003 annual meeting of stockholders,
stockholder proposals must be received by the Secretary of the Company no later
than December 17, 2002, and must otherwise comply with the requirements of Rule
14a-8 of the Securities Exchange Act of 1934 (the "Exchange Act").


                                       2




     Requirements for stockholder proposals to be brought before an annual
meeting. In addition, the Company's Bylaws establish an advance notice
procedure for stockholders who wish to present certain matters before an annual
meeting of stockholders. In general, nominations for the election of directors
may be made by (1) the Board of Directors, (2) any nominating committee
appointed by the Board of Directors or (3) any stockholder entitled to vote who
has written notice delivered to the Secretary of the Company within the Notice
Period (as defined below), which notice must contain specified information
concerning the nominees and concerning the stockholder proposing such
nominations.

     The Company's Bylaws also provide that the only business that may be
conducted at an annual meeting is business that is (1) specified in the notice
of meeting given by or at the direction of the Board of Directors, (2) properly
brought before the meeting by or at the direction of the Board of Directors, or
(3) properly brought before the meeting by any stockholder entitled to vote who
has written notice delivered to the Secretary of the Company within the Notice
Period (as defined below), which notice must contain specified information
concerning the matters to be brought before such meeting and concerning the
stockholder proposing such matters.

     The "Notice Period" is defined as that period not less than 45 days nor
more than 75 days prior to the anniversary of the date on which the Company
first mailed its proxy materials for the previous year's annual meeting of
stockholders. As a result, the Notice Period for the 2003 annual stockholder
meeting will start on February 1, 2003 and end on March 2, 2003.

     If a stockholder who has notified the Company of his or her intention to
present a proposal at an annual meeting does not appear to present his or her
proposal at such meeting, the Company need not present the proposal for vote at
such meeting.

     A copy of the full text of the Bylaw provisions discussed above may be
obtained by writing to the Secretary of the Company. All notices of proposals
by stockholders, whether or not included in the Company's proxy materials,
should be sent to Informatica Corporation, 2100 Seaport Boulevard, Redwood
City, CA 94063, Attention: Corporate Secretary.


                                  PROPOSAL ONE

                              ELECTION OF DIRECTORS


General

     The Company's Board of Directors is currently comprised of five members
who are divided into three classes with overlapping three-year terms. A
director serves in office until his or her respective successor is duly elected
and qualified or until his or her earlier death or resignation. Any additional
directorships resulting from an increase in the number of directors will be
distributed among the three classes so that, as nearly as possible, each class
will consist of an equal number of directors. Vincent Worms resigned as a
director of the Company on February 15, 2002, which created a vacancy on the
Board of Directors. The Board has not nominated a successor for Mr. Worms and
no more than two directors shall be elected at the Annual Meeting.


Nominees for Class II Directors

     Two Class II directors are to be elected at the Annual Meeting for a
three-year term ending in 2005. The Board of Directors has nominated Diaz H.
Nesamoney and A. Brooke Seawell for re-election as Class II directors. Unless
otherwise instructed, the proxyholders will vote the proxies received by them
for the re-election of Messrs. Nesamoney and Seawell. The Company expects that
Messrs. Nesamoney and Seawell will accept such nomination; however, in the
event that either such nominee is unable or declines to serve as a director at
the time of the meeting, the proxies will be voted for any nominee who shall be
designated by the Board of Directors to fill the vacancy. The term of office of
each person elected as director will continue until such director's term
expires in 2005 or until such director's successor has been elected and
qualified.

     The Board of Directors recommends a vote "FOR" the nominees listed above.

other matters which may come before it or as directed by the Board.

     The Audit Committee also meets with the Company's independent auditors on
a quarterly basis, following completion of their quarterly reviews and annual
audit and prior to the Company's earnings announcements, to review the results
of their work. The Audit Committee also meets with the Company's independent
auditors to approve the annual scope of the audit services to be performed.

     Compensation Committee. The Compensation Committee currently consists of
Mr. Pidwell and Mr. Seawell. The Compensation Committee met four times in 2001.
In addition to holding regular meetings, the Compensation Committee took action
by written consent during the course of 2001. The Compensation Committee
reviews and approves the compensation and benefits for the Company's executive
officers, administers the Company's stock plans and performs such other duties
as may from time to time be determined by the Board.


Director Compensation

     Directors do not receive cash compensation for service on the Board of
Directors or any committee thereof. Directors are eligible to receive options
to purchase the Company's Common Stock pursuant to the Company's 1999
Non-Employee Director Stock Incentive Plan (the "1999 Director Plan"), which
provides for annual automatic grants of nonqualified stock options to
continuing non-employee directors. Under the 1999 Director Plan, each
non-employee director will receive a nonqualified stock option grant of 100,000
shares of the Company's Common Stock upon his or her initial election to the
Board of Directors ("Initial Grant"). On the date of each annual stockholders'
meeting, each individual who is at the time continuing to serve as a
non-employee director will automatically be granted an option to purchase
20,000 shares of the Company's Common Stock ("Subsequent Grant"). All options
automati-


                                       5



cally granted to non-employee directors will have an exercise price equal to
100% of the fair market value on the date of grant. Each Initial Grant shall
vest and become exercisable in four equal annual installments and each
Subsequent Grant shall vest and become exercisable on the first anniversary of
the grant date. To date under the 1999 Director Plan, the Company has granted
each of Mr. Seawell, Mr. Worms and Mr. Pidwell an option to purchase 20,000
shares of the Company's Common Stock in both 2000 and 2001, for a total of
120,000 shares of Common Stock, and has granted Ms. Chaffin an option to
purchase 100,000 shares of the Company's Common Stock.

     In addition to the option grants the non-employee directors receive
pursuant to the 1999 Director Plan, the Company granted each of Mr. Seawell,
Mr. Worms and Mr. Pidwell an option to purchase 20,000 shares of the Company's
Common Stock on December 11, 2001. The options were granted pursuant to the
1999 Stock Incentive Plan.


                                  PROPOSAL TWO

               RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

     The Board of Directors has appointed Ernst & Young LLP as independent
auditors of the Company to audit the consolidated financial statements of the
Company for fiscal year 2002. Although ratification by stockholders is not
required by law, the Board has determined that it is desirable to request
ratification of this selection by the stockholders. Notwithstanding its
selection, the Board, in its discretion, may appoint new independent auditors
at any time during the year if the Board believes that such a change would be
in the best interest of Informatica and its stockholders. If the stockholders
do not ratify the appointment of Ernst & Young LLP, the Board may reconsider
its selection.

     Ernst & Young LLP has audited the Company's financial statements since the
Company's inception. A representative of Ernst & Young LLP is expected to be
present at the Annual Meeting with the opportunity to make a statement if he or
she desires to do so, and is expected to be available to respond to appropriate
questions.

     The Board of Directors recommends a vote "FOR" this proposal.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Exchange Act ("Section 16(a)") requires the Company's
executive officers and directors, and persons who own more than 10% of a
registered class of the Company's equity securities ("10% Stockholders"), to
file reports of ownership on Form 3 and changes in ownership on Forms 4 or 5
with the SEC and the Nasdaq Stock Market. Such executive officers, directors
and 10% Stockholders are also required by SEC rules to furnish the Company with
copies of all Section 16(a) forms they file.


     Based solely on its review of the copies of such reports furnished to the
Company and written representations that no other reports were required to be
filed during 2001, the Company believes that its executive officers, directors
and 10% Stockholders have complied with all Section 16(a) filing requirements
applicable to them, with the following exceptions:

    o Barton Foster filed a late Form 4 reporting one transaction in August
      2001.

    o David Pidwell filed a late Form 4 reporting an exercise of stock options
      in May 2001. Mr. Pidwell also filed a Form 5 in February 2001 to report
      three transactions required to be, but not previously, reported on Form 4.

    o Clive Harrison, a former executive officer of the Company, filed a Form
      5 in February 2001 to report five transactions required to be, but not
      previously, reported on Form 4.


          COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The Company's Compensation Committee is currently composed of Mr. Pidwell
and Mr. Seawell. No interlocking relationship exists between any member of the
Company's Compensation Committee and any member of the compensation committee
of any other company, nor has any such interlocking relationship existed in the
past. No member of the Compensation Committee is or was formerly an officer or
an employee of the Company.

----------
(1)   The options in this table are incentive stock options or nonstatutory
      stock options granted under the 1999 Stock Incentive Plan and 1999
      Director Plan, as applicable, and have exercise prices equal to the fair
      market value of the Company's Common Stock on the date of grant. All such
      options have ten-year terms and vest over a period of four years at a
      rate of 2.03% each month.

(2)   The Company granted options to purchase 3,847,350 shares of Common Stock
      in the year ended December 31, 2001.

(3)   The options in this table may terminate before their expiration upon the
      termination of optionee's status as an employee or consultant or upon the
      optionee's disability or death.

(4)   Under rules promulgated by the SEC, the amounts in these two columns
      represent the hypothetical gain or "option spread" that would exist for
      the options in this table based on assumed stock price appreciation from
      the date of grant until the end of such options' ten-year term at assumed
      annual rates of 5% and 10%. Annual compounding results in total
      appreciation of 63% (at 5% per year) and 159% (at 10% per year). The 5%
      and 10% assumed annual rates of appreciation are specified in SEC rules
      and do not represent the Company's estimate or projection of future stock
      price growth. The Company does not necessarily agree that this method can
      properly determine the value of an option, and there can be no assurance
      that the potential realizable values shown in this table will be
      achieved.

                         REPORT OF THE AUDIT COMMITTEE
                           OF THE BOARD OF DIRECTORS

     With respect to the Company's financial reporting process, the management
of the Company is responsible for (1) establishing and maintaining internal
controls and (2) preparing the Company's consolidated financial statements. The
independent auditors are responsible for auditing these financial statements.
It is the responsibility of the Audit Committee to oversee these activities.
The Board of Directors has determined that each member of the Audit Committee
is "independent" as required by the listing standards of the Nasdaq National
Market. The Board of Directors has adopted a written charter for the Audit
Committee. In the performance of its oversight function, the Audit Committee
has:

    o reviewed and discussed the audited financial statements with management;


    o discussed with Ernst & Young LLP, its independent auditors, the matters
      required to be discussed by the Statement on Auditing Standards No. 61,
      Communication with Audit Committees, as currently in effect;

    o received the written disclosures and the letter from the independent
      accountants required by Independence Standards Board Standard No. 1,
      Independence Discussions with Audit Committees, as currently in effect;

    o considered whether the provision of information technology consulting
      services relating to financial information systems design and
      implementation and other non-audit services by Ernst & Young LLP is
      compatible with maintaining Ernst & Young LLP's independence and has
      discussed with Ernst & Young LLP the auditors' independence.

     Based upon the reports and discussions described in this Report, the Audit
Committee recommended to the Board of Directors that the audited financial
statements be included in the Company's Annual Report on Form 10-K for the year
ended December 31, 2001.



                                        AUDIT COMMITTEE OF
                                        THE BOARD OF DIRECTORS

                     REPORT OF THE COMPENSATION COMMITTEE

     The Compensation Committee was formed in March 1999 and currently consists
of Messrs. Seawell and Pidwell. The Compensation Committee generally reviews
and approves the Company's executive compensation policies, including the base
salary levels and target incentives for the Company's executive officers at the
beginning of each year, and approves the performance objectives of the
executive officers in their areas of responsibility. The Compensation Committee
also administers the Company's stock plans, including the Company's 1999 Stock
Incentive Plan, the 2000 Employee Stock Incentive Plan (the "2000 Stock Plan")
and the 1999 Employee Stock Purchase Plan. No member of the Compensation
Committee is a former or current officer or employee of Informatica or any of
its subsidiaries. Certain meetings of the Compensation Committee are also
attended by Mr. Dhillon, Mr. Nesamoney and Earl Fry, who provide background and
market information and make recommendations to the Compensation Committee on
salary levels, officer performance objectives, and corporate financial goals.
However, Mr. Dhillon, Mr. Nesamoney, and Mr. Fry are not entitled to vote on
any actions taken by the Compensation Committee.


Executive Officer Compensation Programs

     The objectives of the executive officer compensation program are to
attract, retain, motivate and reward key personnel who possess the necessary
leadership and management skills, through competitive base salary, annual cash
bonus incentives, long-term incentive compensation in the form of stock
options, and various benefits, including medical and life insurance plans. The
executive compensation policies of the Compensation Committee are intended to
combine competitive levels of compensation and rewards for above average
performance and to align relative compensation with the achievements of key
business objectives, optimal satisfaction of customers, and maximization of
stockholder value. The Compensation Committee believes that stock ownership by
management is beneficial in aligning management and stockholder interests,
thereby enhancing stockholder value.

     Base Salaries. Salaries for the Company's executive officers are
determined primarily on the basis of the executive officer's level of
responsibility, general salary practices of peer companies and the officer's
individual qualifications and experience. The base salaries are reviewed
annually and may be adjusted by the Compensation Committee in accordance with
certain criteria which include individual performance, the functions performed
by the executive officer, the scope of the executive officer's on-going duties,
general changes in the compensation peer group in which the Company competes
for executive talent, and the Company's financial performance generally. The
weight given each such factor by the Compensation Committee may vary from
individual to individual.

     Incentive Bonuses. The Compensation Committee believes that a cash
incentive bonus plan can serve to motivate the Company's executive officers and
management to address annual performance goals, using more immediate measures
for performance than those reflected in the appreciation in value of stock
options. The bonus amounts are based upon recommendations by management and a
subjective consideration of factors including such officer's level of
responsibility, individual performance, contributions to the Company's success
and the Company's financial performance generally.

     Stock Option Grants. Stock options may be granted to executive officers
and other employees under the 1999 Stock Incentive Plan or the 2000 Stock Plan.
Because of the direct relationship between the value of an option and the stock
price, the Compensation Committee believes that options motivate executive
officers to manage the Company in a manner that is consistent with stockholder
interests. Stock option grants are intended to focus the attention of the
recipient on the Company's long-term performance which the Company believes
results in improved stockholder value, and to retain the services of the
executive officers in a competitive job market by providing significant
long-term earnings potential. To this end, stock options generally vest and
become fully exercisable over a four-year period. The principal factors
considered in granting stock options to executive officers of the Company are
prior performance, level of responsibility, other compensation and the
executive officer's ability to influence the Company's long-term growth and
profitability. However, neither the 1999 Stock Incentive Plan nor the 2000
Stock Plan provides any quantitative method for weighting these factors, and a
decision to grant an award is primarily based upon a subjective evaluation of
the past as well as future anticipated performance of the executive officer.


                                       13




     In July 2001, the Board approved a voluntary stock option exchange program
for the Company's employees (the "Exchange Program") because the Board
determined that existing options no longer had sufficient value to motivate and
retain the Company's employees in the current market environment. Under the
Exchange Program, eligible employees, including Mr. Fry and Mr. Foster, were
given the opportunity to cancel outstanding options to purchase the Company's
Common Stock that were previously granted to them in exchange for a new
non-qualified stock option grant for an equal number of shares of the Company's
Common Stock to be granted at least six months and one day from the
cancellation date of the exchanged options. No members of the Company's Board
of Directors or executive officers, other than Mr. Fry and Mr. Foster, were
eligible for the Exchange Program. On March 15, 2002, replacement options were
granted to participating employees under the Exchange Program.


     Other Compensation Plans. The Company has adopted certain general employee
benefit plans in which executive officers are permitted to participate on
parity with other employees. The Company also provides a 401(k) deferred
compensation plan.


     Deductibility of Compensation. Section 162(m) of the Internal Revenue Code
("IRC") disallows a deduction by the Company for compensation exceeding $1.0
million paid to certain executive officers, excluding, among other things,
performance based compensation. Because the compensation paid to executive
officers has not approached the limitation, the Compensation Committee has not
had to use any of the available exemptions from the deduction limit with regard
to such officers' compensation. The Compensation Committee remains aware of the
IRC Section 162(m) limitations, and the available exemptions, and will address
the issue of deductibility when and if circumstances continue to warrant the
use of such exemptions.


Chief Executive Officer Compensation

     The compensation of the Chief Executive Officer is reviewed annually on
the same basis as discussed above for all executive officers. Mr. Dhillon's
base salary for the year ended December 31, 2001 was $247,083. Mr. Dhillon's
base salary was established in part by comparing the base salaries of chief
executive officers at other companies of similar size. Mr. Dhillon's base
salary was below the median of the base salary range for Chief Executive
Officers of comparable companies. Mr. Dhillon received an option to purchase
100,000 shares of the Company's Common Stock and no bonus for the year ended
December 31, 2001.
