Exhibit 31.1

CERTIFICATION OF CHIEF EXECUTIVE
OFFICER

I, Todd E. Wille, certify that:

1.I have reviewed this quarterly report on Form
10-Q of Unify Corporation;

2.Based on
my knowledge, this quarterly report does not contain any untrue statement of a
material fact or omit to state a material fact necessary to make the statements
made, in light of the circumstances under which such statements were made, not
misleading with respect to the period covered by this quarterly report;

3.Based on
my knowledge, the financial statements, and other financial information included
in this quarterly report, fairly present in all material respects the financial
condition, results of operations and cash flows of the registrant as of, and
for, the periods presented in this quarterly report;

4.The
registrants other certifying officers and I are responsible for establishing
and maintaining disclosure controls and procedures (as defined in Exchange Act
Rules 13a-15(e) and 15d-15(e)) and internal controls over financial reporting
(as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant
and we have:

(a) designed such disclosure controls and procedures, or
caused such disclosure controls and procedures to be designed under our
supervision, to ensure that material information relating to the registrant,
including its consolidated subsidiaries, is made known to us by others within
those entities, particularly during the period in which this quarterly report is
being prepared;

(b) designed such internal controls over financial reporting,
or caused such internal controls over financial reporting to be designed under
our supervision, to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of the financial statements for external
purposes in accordance with generally accepted accounting principles;
and

(c) evaluated the effectiveness of the registrants disclosure
controls and procedures and presented in this report our conclusions about the
effectiveness of the disclosure controls and procedures as of the end of the
period covered by this report based on such evaluation; and

(d) disclosed in this report any change in the registrants
internal control over financial reporting that occurred during the registrants
most recent fiscal quarter (the registrants third fiscal quarter in the case of
an annual report) that has materially affected, or is reasonably likely to
materially affect, the registrants internal control over financial reporting;
and

5.The
registrants other certifying officers and I have disclosed, based on our most
recent evaluation of internal control over financial reporting, to the
registrants auditors and the audit committee of the registrants board of
directors (or persons performing the equivalent functions):

(a) all significant deficiencies and material weaknesses in
the design or operation of internal controls over financial reporting which are
reasonably likely to adversely affect the registrants ability to record,
process, summarize and report financial information; and

(b) any fraud, whether or not material, that involves
management or other employees who have a significant role in the registrants
internal control over financial reporting.
