                                PROXY STATEMENT


  This Proxy Statement is furnished in connection with the solicitation of
Proxies by the Board of Directors (the "Board") of USDATA Corporation (the
"Company") for use at the Annual Meeting of Stockholders to be held on Monday,
June 1, 1998 (such meeting and any adjournment or adjournments thereof referred

Notice of Annual Meeting of Stockholders and in this Proxy Statement.  The

VOTING SECURITIES

  Only the holders of shares of common stock, par value $.01 per share (the
"Common Stock"), of the Company of record at the close of business on April 24,
1998 (the "Shares") are entitled to receive notice of, and to vote at, the
Annual Meeting.  On that date, there were 11,483,326 Shares outstanding and
entitled to be voted at the Annual Meeting.  It is the intention of the persons
named in the Proxy to vote as instructed by the stockholders or, if no
instructions are given, to vote as recommended by the Board.  Each stockholder
has one vote per Share on all business of the Annual Meeting.

  The seven nominees receiving the highest number of affirmative votes of the
Shares present or represented and entitled to be voted will be elected as
directors. Votes withheld from any director, abstentions and broker non-votes
will be counted for purposes of determining the presence of a quorum for the
transaction of business at the Annual Meeting.  Abstentions are counted in
tabulations of the votes cast on proposals presented to stockholders.  Broker
non-votes are not counted for purposes of determining whether a proposal has
been approved.

REVOCABILITY OF PROXY

  Execution of the enclosed Proxy will not affect a stockholder's right to
attend the Annual Meeting and vote in person.  A stockholder, in exercising his
right to vote in person at the Annual Meeting, effectively revokes all
previously executed Proxies.  In addition, the Proxy is revocable at any time
prior to the effective exercise thereof by filing notice of a revocation with
the Secretary of the Company or by filing a duly executed Proxy bearing a later
date.

PERSONS MAKING THE SOLICITATION

  The solicitation of this Proxy is made by the Company.  The cost of soliciting
Proxies on behalf of the Company, including the actual expenses incurred by
brokerage houses, nominees and fiduciaries in forwarding Proxy materials to
beneficial owners, will be borne by the Company.  In addition to solicitation by
mail, certain officers and other employees of the Company may solicit Proxies on
behalf of the Company in person or by telephone.

DIRECTORS' COMPENSATION

          Directors are elected annually and hold office until their successors
are elected and have qualified or until their earlier resignation or removal.
Directors are reimbursed for travel expenses incurred in connection with
attendance at meetings or other Company business, but directors are not
compensated for their services as directors.

DIRECTORS' STOCK OPTIONS

          Directors who are not employees of the Company and its subsidiaries or
Safeguard and its wholly owned subsidiaries ("Eligible Directors") are entitled
to participate in the 1994 Equity Compensation Plan ("1994 Plan").  No options
were granted to Directors in 1997.

COMMITTEES AND MEETINGS OF THE BOARD OF DIRECTORS

          The Board held four meetings in 1997.  The Company's Board has
appointed standing Compensation, Executive, and Audit Committees.  The
Compensation Committee reviews and recommends the compensation arrangements for
senior management of the Company, including salaries, bonuses and grants of
options to purchase shares of Common Stock under the Company's stock option and
equity compensation plans.  The Compensation Committee met two times during
1997.  The Executive Committee, which did not meet during 1997, has the
authority to approve transactions on behalf of the Company that do not exceed $1
million in the aggregate, except where such functions are required by law to be
approved by the full Board of Directors.  The Audit Committee recommends the
firm to be appointed as independent certified public accountants to audit the
Company's financial statements, discusses the scope and results of the audit
with the independent certified public accountants, reviews with management and
the independent certified public accountants the Company's interim and 

 
year-end operating results, considers the adequacy of the internal accounting
controls and audit procedures of the Company and reviews the non-audit services
to be performed by the independent certified public accountants. The Audit
Committee met once during 1997. All of the directors attended at least 75% of
the total number of Board and Committee meetings of which they were members
during the period in which they served as a director, except Mr. Johnson, who
attended 67% of the meetings.


                   REPORT OF THE BOARD COMPENSATION COMMITTEE

          The Compensation Committee of the Board (the "Compensation Committee")
reviews and approves compensation levels recommended by management, including
incentive compensation, for the executives of the Company, and administers the
Company's stock option plans.  Messrs. Hopper, Messman and Spector currently
constitute the Compensation Committee.

          The Company's former acting Chief Executive Officer, Bill E. Newell,
is an executive of Safeguard and was compensated while acting as Chief Executive
Officer of the Company by Safeguard for services rendered to Safeguard and its
affiliated partnership companies, including the Company. Decisions regarding Mr.
Newell's cash compensation and other benefits paid or awarded to Mr. Newell
during 1997 were determined by the Compensation Committee of the Board of
Directors of Safeguard. Therefore, with respect to compensation issues relating
to Mr. Newell, this report relates only to options which have been granted to
Mr. Newell by the Company to purchase Shares of the Company.

EXECUTIVE COMPENSATION POLICIES

          The Company is in a highly competitive industry.  In order to succeed,
the Company believes that it must be able to attract and retain outstanding
executives, promote among them the economic benefits of stock ownership in the
Company, and motivate and reward executives who, by their industry, loyalty and
exceptional service, make contributions of special importance to the success of
the business of the Company.  The Company has structured its executive
compensation program to support the strategic goals and objectives of the
Company.

          Base compensation levels and benefits are initially established for
new executives on the basis of subjective factors, with reference to the
experience and achievements of the individual and the level of responsibility to
be assumed in the Company.  Annual increases are determined subjectively based
on the achievement of financial and strategic objectives, levels of individual
responsibility and performance, and general levels of inflation.  Annual cash
bonuses are intended to create an incentive for executives who significantly
contribute to and influence the Company's strategic plans and are responsible
for the Company's performance. The aims are to focus executives' attention on
areas such as profitability and asset management, to encourage teamwork and to
tie executive pay to corporate performance goals which are consistent with the
long-term goals of stockholders and other investors.  Bonuses are awarded based
on the achievement of annual financial and strategic goals approved by the
Compensation Committee at the beginning of each year.  These goals may include a
target range of pretax earnings, earnings per share, return on equity, or other
objective measurement consistent with long-term stockholder goals.  The
Compensation Committee approves a target range for specific financial and/or
strategic goals and a range of potential bonus amounts for each executive,
stated as a percentage of base salary.  Ranges of potential bonuses are
determined based upon the executive's ability to affect the Company's
performance.  Actual bonuses are awarded following the year-end based on the
actual achievement level of the specified corporate goals compared to the target
range of achievement.  For fiscal 1997, the Compensation Committee determined
that bonuses would be awarded based primarily upon the achievement of certain
strategic objectives and upon a target range for revenue growth and 

 
pretax earnings, with the ability to adjust the payout among the participants
based on individual performance.

          Grants of Company stock options are intended to align the interests of
executives and key employees with the long-term interests of the Company's
stockholders and other investors and to encourage executives and key employees
to remain in the Company's employ. Grants are not made in every year, but are
awarded subjectively based on a number of factors, including the individual's
level of responsibility, the amount and term of options already held by the
individual, the individual's contributions to the achievement of the Company's
financial and strategic objectives as defined in the Company's annual plan, and
the Company's achievement of its financial and strategic objectives, which may
include the goals described above as well as developing strategic alliances,
identifying and exploiting markets, expanding existing market share and
penetration, expanding operating capabilities and improving net operating
margins and return on equity.

     The Compensation Committee is aware that Internal Revenue Code section
162(m) provides that publicly held companies may not deduct in any taxable year
compensation in excess of one million dollars paid to any of the individuals
named in the Summary Compensation Table that is not "performance based" as
defined in section 162(m). The Company believes that stock options granted under
its 1994 Equity Compensation Plan meet the performance-based exception under
section 162(m).  The Compensation Committee believes that annual levels of
executive compensation that are not performance based are not likely to exceed
one million dollars in the foreseeable future, and the benefit to the Company of
retaining the ability to exercise discretion under the Company's remaining
incentive compensation plans outweighs the limited risk of loss of tax
deductions under section 162(m).  Therefore, the Company does not currently
intend to seek to qualify any of its other incentive compensation plans under
section 162(m).

CEO COMPENSATION

     Mr. Merry's compensation upon joining the Company on July 28, 1997,
consisted of an annual base salary of $225,000 and a sign-on bonus of $63,000.
Mr. Merry was not eligible for any performance-based bonus in 1997.

OTHER EXECUTIVE COMPENSATION

     The Compensation Committee did not award executive cash bonuses in 1997 due
to the Company's failure to meet the bonus objectives discussed previously.
During 1997, the Compensation Committee granted options under the Company's 1994
Plan to certain of its new executives and employees and to many of its current
executives and employees.  The relative number of options granted to executives
and employees was based on each such individual's current responsibilities.


By the Compensation Committee:

Max D. Hopper       Jack L. Messman      Arthur R. Spector

 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     During 1997, the Compensation Committee consisted of Messrs. Hopper,
Messman and Spector.  Mr. Spector served as Chairman of the Board of the Company
during that time.

(1)  The potential realizable values are based on an assumption that the stock
     price of the shares of Common Stock of the Company or Safeguard appreciate
     at the annual rate shown (compounded annually) from the date of grant until
     the end of the option term.  These values do not take into account amounts
     required to be paid as income taxes under the Code or any applicable state
     laws or option provisions providing for termination of an option following
     termination of employment, nontransferability or vesting over periods of up
     to four years.  These amounts are calculated based on the requirements
     promulgated by the Securities and 

 
     Exchange Commission and do not reflect the Company's estimate of future
     stock price growth of the shares of Common Stock of the Company.

(2)  Each option vests 25% each year commencing on the first anniversary of the
     grant date, has an eight-year term and continues vesting and remains
     exercisable so long as employment with the Company or one of its
     subsidiaries continues.  The option exercise price may be paid in cash or
     by (i) delivery of previously acquired shares or (ii) same day sales, i.e.
     cashless broker's exercises.

(3)  All options have an exercise price at least equal to the fair market value
     on the date of grant of the shares subject to each option.

(4)  Options granted to Mr. Newell on December 11, 1997, to purchase shares of
     Common Stock of Safeguard under Safeguard's 1990 Stock Option Plan.  The

(1)  The value of unexercised in-the-money options is calculated based upon (i)
     the fair market value per share of the stock at December 31, 1997, less the
     option exercise price, multiplied by (ii) the number of shares subject to
     an option.  On December 31, 1997, the fair market value of a share of the
     Company's common stock was $4.625 and the fair market value of Safeguard's
     Common Stock was $31.375.  This table is presented solely for the purpose
     of complying with the rules of the Securities and Exchange Commission and
     does not necessarily reflect the amounts optionees will actually receive
     upon the sale of any shares acquired upon the exercise of the options.

 
                            STOCK PERFORMANCE GRAPH

      The following chart compares the cumulative total stockholder return on
the Company's Common Stock for the period beginning with the commencement of the
Company's initial public offering on June 16, 1995 through December 31, 1997
with the cumulative total return on the Nasdaq Index and the cumulative total
return for a peer group index for the same period.  The peer group consists of
SIC Code 737--Computer Programming and Data Processing Services.  The comparison
assumes that $100 was invested on June 16, 1995 in the Company's Common Stock
and in each of the comparison indices, and assumes reinvestment of dividends.
The Company has historically reinvested earnings in the growth of its business
and has not paid cash dividends on its Common Stock.

                              CERTAIN TRANSACTIONS

      The Company and Safeguard are parties to an Administrative Services
Agreement pursuant to which Safeguard provides the Company with administrative
support services for a monthly fee of $30,000.  The administrative support
services include consultation regarding the Company's general management,
investor relations, financial management, certain legal services, insurance
programs administration, audit administration and tax research and planning.
The annual administrative services fee does not cover extraordinary services
provided by Safeguard to the Company or services that are contracted out.  The
initial term of the agreement expired on December 31, 1997, and has been
extended until December 31, 1998, with annual renewals thereafter by mutual
agreement between the parties.  The Company expensed $360,000 during 1997 for
these services.

      In connection with the purchase of 273,910 shares of Common Stock (the
"Restricted Stock") on February 20, 1995 at a purchase price of $3.50 per share,
William G. Moore, Jr., the former President and Chief Executive Officer of the
Company, borrowed $958,685 from the Company evidenced by a note (the "Note")
bearing interest at the rate of 7.75% per annum.  Mr. Moore resigned as an
officer and director of the Company on March 10, 1997.  Pursuant to the terms of
a Severance Agreement, Mr. Moore was employed by the Company as a consultant
until December 31, 1997 at a salary level of $275,000.  In addition, the Company
has repurchased all of the Restricted Stock in exchange for the cancellation of
all outstanding principal and accrued interest under the Note, which totaled
$958,685 and $161,539, respectively, as of March 10, 1997.

      On November 8, 1994, Safeguard and certain other investors acquired
6,198,808 shares of Common Stock from the Company's then majority shareholders
for an aggregate purchase price of approximately $18 million.  In connection
therewith, the Company granted to Safeguard a warrant to purchase 698,238 shares
of Common Stock and to Arthur R. Spector, a director of the Company, a warrant
to purchase 77,582 shares of Common Stock.  Each warrant is currently
exercisable at an exercise price of $3.02 per share.

      The Company and Bob B. Midyett, Jr. were parties to an Employment
Agreement under which Mr. Midyett initially served as Chief Executive Officer
and served as Senior Advisor to the Company.  The Employment Agreement had an
initial term of three years, commencing November 8, 1994.  Pursuant to the
Employment Agreement, Mr. Midyett 

 
received annual compensation of $360,000 and reimbursement of certain expenses.
Effective November 8, 1997, the Employment Agreement expired and was not
renewed. For as long as he owns at least 5% of the outstanding Common Stock of
the Company, Mr. Midyett is entitled to serve on the Board of Directors of the
Company.


                         INDEPENDENT PUBLIC ACCOUNTANTS
                                        
          Since 1992, the Company has retained Price Waterhouse LLP as its
independent public accountants, and it intends to retain Price Waterhouse LLP
for the current year ending December 31, 1998.  A representative of Price
Waterhouse LLP is expected to be present at the Annual Meeting and will have an
opportunity at the meeting to make a statement if he desires to do so and will
be available to respond to appropriate questions.


            SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

          Section 16(a) of the Securities Exchange Act of 1934 requires the
Company's directors and executive officers and persons who own more than ten
percent of a registered class of the Company's equity securities ("10%
Stockholders") to file reports of ownership and changes in ownership of Common
Stock and other equity securities of the Company with the Securities and
Exchange Commission ("SEC").  Officers, directors and 10% Stockholders are
required by SEC regulation to furnish the Company with copies of all Section
16(a) forms that they file.  Based solely on its review of the copies of such
forms received by it and written representations from certain reporting persons
that no other reports were required for those persons, the Company believes that
during the period from January 1, 1997 to December 31, 1997, all Section 16(a)
filing requirements applicable to its officers, directors and 10% Stockholders
were complied with, except for late Forms 4 filed by Mr. Midyett and Safeguard
Scientifics, Inc.


                                 OTHER MATTERS

          The Company is not aware of any other business to be presented at the
Annual Meeting.  If any other matters should properly come before the Annual
Meeting, however, the enclosed Proxy confers discretionary authority with
respect thereto.

          The President's Letter and the Company's 1997 Annual Report on Form
10-K, including financial statements and other information with respect to the
Company and its subsidiaries, is being mailed simultaneously to the stockholders
but is not to be regarded as proxy solicitation material.
