    Re:  Legality of the 10 1/2% Senior Subordinated Notes Due 2012 and
         related subsidiary guarantees
         --------------------------------------------------------------

Ladies and Gentlemen:

         We have acted as counsel for NDCHealth Corporation, a Delaware
corporation (the "Company"), in connection with the preparation of the
registration statement on Form S-4 filed with the Securities and Exchange
Commission under the Securities Act of 1933, as amended, relating to the
proposed exchange of up to $200,000,000 aggregate principal amount of 10 1/2%
Senior Subordinated Notes Due 2012 (the "New Notes") of the Company for a like
principal amount of the Company's issued and outstanding 10 1/2% Senior
Subordinated Notes Due 2012 (the "Old Notes"). Certain domestic subsidiaries of
the Company named in the Indenture (defined below) (the "Subsidiary Guarantors")
will unconditionally guarantee the obligations of the Company under the New
Notes (the "Note Guarantees").

         In so acting, we have reviewed the Indenture, dated as of November 26,
2002, among the Company, the Subsidiary Guarantors and Regions Bank, as Trustee
(the "Indenture"). We have also reviewed such matters of law and examined
original, certified, conformed or photographic copies of such other documents,
records, agreements and certificates as we have deemed necessary as a basis for
the opinions hereinafter expressed. In such review, we have assumed the
genuineness of signatures on all documents submitted to us as originals and the
conformity to original documents of all copies submitted to us as certified,
conformed or photographic copies.

         For purposes of the opinions below, we have assumed that the execution
and delivery of, and the performance of all obligations under, the Indenture has
been duly authorized by all requisite action by the Trustee and the Subsidiary
Guarantors incorporated in states other than Delaware and that the Indenture has
been duly executed and delivered by the Trustee and the Subsidiary Guarantors
incorporated in states other than Delaware, and is a valid and binding agreement
of, the Trustee, enforceable against the Trustee in accordance with its terms.

         This opinion is limited in all respects to the laws of the State of New
York and the Delaware General Corporation Law, and no opinion is expressed with
respect to the laws of any other jurisdiction or any effect which such laws may
have on the opinions expressed herein. This opinion is limited to the matters
stated herein and no opinion is implied or may be inferred beyond the matters
expressly stated herein.

         Based upon the foregoing, and subject to the assumptions, limitations
and qualifications set forth herein, we are of the opinion that:

                  (1)      The Indenture has been duly authorized, executed and
         delivered by the Company and the Subsidiary Guarantors and constitutes
         a valid and binding obligation of the Company and the Subsidiary
         Guarantors, enforceable against the Company and the Subsidiary
         Guarantors in accordance with its terms, subject, as to enforcement of
         remedies, to bankruptcy, insolvency, reorganization, moratorium or
         similar laws affecting the rights and remedies of creditors generally
         and to the effect of general principles of equity.

                  (2)      The New Notes have been duly authorized by the
         Company and, when executed and delivered by the Company and duly
         authenticated in accordance with the terms of the Indenture and
         delivered in exchange for the Old Notes, will constitute valid and
         binding obligations of the Company, enforceable against the Company in
         accordance with their terms, subject, as to enforcement of remedies, to
         bankruptcy, insolvency, reorganization, moratorium or similar laws
         affecting the rights and remedies of creditors generally and to the
         effect of general principles of equity.

                  (3)      The Note Guarantees have been duly authorized by the
         Subsidiary Guarantors and, when the New Notes are executed and
         delivered by the Company and duly authenticated in accordance with the
         terms of the Indenture and delivered in exchange for the Old Notes,
         will constitute valid and binding obligations of the Subsidiary
         Guarantors, enforceable against the Subsidiary Guarantors in accordance
         with their terms, subject, as to enforcement of remedies, to
         bankruptcy, insolvency, reorganization, moratorium or similar laws
         affecting the rights and remedies of creditors generally and to the
         effect of general principles of equity.

         This opinion is given as of the date hereof, and we assume no
obligation to advise you after the date hereof of facts or circumstances that
come to our attention or changes in law that occur, which could affect the
opinions contained herein. This opinion may not be furnished to or relied upon
