Ladies and Gentlemen:

     We have served as special New Jersey counsel for OMR Systems Corporation, a
New Jersey corporation (the "New Jersey Guarantor"), in connection with the
issuance and exchange of up to $205,000,000 aggregate original principal amount
of 11 3/4% Senior Subordinated Notes due 2013 (the "Exchange Notes") of SS&C
Technologies, Inc., A Delaware corporation (the "Company"), and the guarantee by
the Guarantors (as defined below), including the New Jersey Guarantor, of the
obligations represented by the Exchange Notes (the "Exchange Guarantees" and,
together with the Exchange Notes, the "New Securities").

     The New Securities are to be issued pursuant to an Indenture, dated as of
November 23, 2005 (the "Original Indenture"), among the Company, Sunshine
Acquisition II, Inc. ("Sunshine"), and the guarantors listed on the signature
page thereto (collectively, the "Guarantors"), and Wells Fargo Bank, National
Association, as trustee (the "Trustee"), as supplemented by the First
Supplemental Indenture, dated as of April 27, 2006 (the "First Supplemental
Indenture") (the Original Indenture, as supplemented by such First Supplemental
Indenture being referred to collectively as the "Indenture"). The New Securities
are to be issued in an exchange offer (the "Exchange Offer") for a like
aggregate original principal amount of currently outstanding 11 3/4% Senior
Subordinated Notes due 2013 (collectively, the "Old Notes") and the guarantees
of the obligations represented by the Old Notes in accordance with the terms of
a Registration Rights Agreement, dated as of November 23, 2005, by and among the
Company, Sunshine, the Guarantors and the Initial Purchasers (as defined
therein), as supplemented by the Joinder Agreement, dated as of April 27, 2006.

     This opinion is being furnished to you at the request of our client
pursuant to the Indenture. Capitalized terms used herein that are not defined
herein shall have the meanings set forth in the Indenture.

     In rendering the opinions set forth herein, we have examined originals, or
copies certified or otherwise identified to our satisfaction, of the following
documents:

          (a) a copy, as executed, of the Indenture;

          (b) a copy, as executed, of the Note Guarantee, the terms of which are
set forth in the Indenture (the "Note Guarantee");

          (c) a copy of the Certificate of Incorporation and Merger of the New
Jersey Guarantor, filed in the Office of the Treasurer of the State of New
Jersey on May 27, 1999;

          (d) a copy of the Bylaws of the New Jersey Guarantor, as amended by
Amendment No. 1 to Bylaws of OMR Systems Corporation;

          (e) a copy of the Written Consent in Lieu of a Special Meeting of the
Board of Directors of the New Jersey Guarantor, dated November 23, 2005; and

          (f) a Certificate of the Treasurer of the New Jersey Guarantor, dated
as of the date hereof, attesting to (i) true, correct and complete copies of the
Certificate of Incorporation and Merger of the New Jersey Guarantor, as amended,
the Bylaws of the New Jersey Guarantor, as amended, and the resolutions of the
Board of Directors of the New Jersey Guarantor approving, among other things,
the Loan Documents (as defined in the immediately succeeding paragraph), each as
certified to us by the New Jersey Guarantor to have been in effect on November
23, 2005, and (ii) the authorization, incumbency and signatures of certain
officers of the New Jersey Guarantor.

     The documents in (a) and (b) above are herein referred to collectively as
the "Loan Documents." We call to your attention that we have not examined any
court, real estate or commercial financing records. We have also made such
examination of law as we have deemed necessary for purposes of this opinion.

     In our examination, we have assumed the genuineness of all signatures, the
legal capacity of all natural persons, the authenticity of all documents
submitted to us as originals, the conformity to the original documents of all
documents submitted to us as certified or photocopies, the authenticity of the
originals of such latter documents, the accuracy and completeness of all
documents and records reviewed by us, the accuracy, completeness and
authenticity of each certificate issued by any government official, office or
agency and the absence of change in the information contained therein from the
effective date of any such certificate.

     We have assumed that each of the parties to the Loan Documents other than
the New Jersey Guarantor (the "Other Parties") has satisfied all applicable
legal requirements necessary to make the Loan Documents enforceable against it
and has complied with all legal requirements pertaining to its status as such
status relates to its rights to enforce the Loan Documents against the New
Jersey Guarantor. We have also assumed that the conduct of the parties to the
Loan Documents complies with any requirements of good faith, fair dealing and
absence of unconscionability, and there has not been any mutual mistake of fact,
fraud, duress or undue influence.

     As to any facts material to our opinions expressed herein, we have relied
upon the representations and warranties of the Company and the New Jersey
Guarantor contained in the Loan Documents and upon a certificate of Patrick J.
Pedonti, Treasurer of the New Jersey Guarantor, with respect to certain factual
matters. In this regard, we have assumed the due authorization, execution and
delivery of the Loan Documents by all of the Other Parties thereto, that all of
the Other Parties thereto have full power and legal right to enter into the Loan
Documents and to consummate the transactions contemplated thereby, and that each
of the Loan Documents constitutes a legal, valid and binding obligation of each
of the Other Parties thereto.

     To the extent that a statement herein is qualified by the phrases "to our
knowledge" or "known to us", or by similar phrases, it is intended to indicate
that, during the course of our representation of the New Jersey Guarantor in
connection with the Loan Documents, no information that would give us current
actual knowledge of the inaccuracy of such statement has come to the attention
of those attorneys presently in this firm who have rendered substantive legal
services in connection with the representation of the New Jersey Guarantor with
respect to the Loan Documents. However, we have not undertaken any independent
investigation or review to determine the accuracy of any such statement, and any
limited inquiry undertaken by us during the preparation of this opinion letter
should not be regarded as such an investigation or review. No inference as to
our knowledge of any matters bearing on the accuracy of any such statement
should be drawn from the fact of our representation of the New Jersey Guarantor.

     Our opinion is limited in all respects to the laws of the United States and
the State of New Jersey and we express no opinion as to the laws of any other
jurisdiction. In this regard we note that each of the Loan Documents recites
that it is governed by the laws of the State of New York, and for purposes of
rendering the opinions herein, we have assumed, with your permission, that
insofar as the laws of such jurisdiction are applicable to the matters set forth
herein, such laws are identical to and will be interpreted in all respects in
the same manner as the laws of the State of New Jersey without regard to
conflicts of laws principles.

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

     1. The New Jersey Guarantor had the corporate power to execute and deliver
each of the Loan Documents and to perform its obligations thereunder.

     2. The execution and delivery by the New Jersey Guarantor of each of the
Loan Documents and the performance by the New Jersey Guarantor of its
obligations under the Loan Documents were duly authorized by all necessary
corporate action on the part of the New Jersey Guarantor.

     3. The execution and delivery by the New Jersey Guarantor of each of the
Loan Documents and the performance of the obligations of the New Jersey
Guarantor thereunder did

not violate (a) the provisions of the New Jersey Guarantor's Certificate of
Incorporation and Merger or Bylaws, or (b) any federal or New Jersey law
applicable to the New Jersey Guarantor.

     Our opinions expressed above are subject to the following additional
qualifications:

          (a) We express no opinion as to the effect of any federal or New
Jersey law, rule or regulation concerning securities, trademarks, patents,
copyrights, trade secrets, antitrust, taxes, pollution, hazardous substances or
environmental protection, zoning, land use, building, construction, labor,
protection of disabled persons, or occupational health and safety in respect of
the transactions contemplated by or referred to in any of the Loan Documents, or
as to any statutes, ordinances, administrative decisions, rules or regulations
of any county, town, municipality or special political subdivision (whether
created or enabled through legislative action at the state or regional level).

          (b) We express no opinion as to the existence of or title to property
or encumbrances thereon, the description of any property or the creation or the
perfection of any security interest or the priority of any security interest or
the perfection or the priority of any mortgage or other lien.

          (c) Our opinion in paragraph 3 above as to compliance with certain
statutes, rules is based upon a review (as limited by (a) above) of those
federal and New Jersey statutes, rules and regulations which, in our experience,
are normally applicable to transactions of the type contemplated by the Loan
Documents.

          (d) In rendering this opinion, we have assumed that: (i) the Other
Parties have acted without notice of any defense against the enforcement of any
rights created by the transactions contemplated by the Loan Documents; (ii)
there are no agreements or understandings among the parties, written or oral,
and there is no usage of trade or course of prior dealing among the parties that
would, in either case, define, supplement or qualify the terms of the Loan
Documents; (iii) each applicable statute, rule, regulation, order and agency
action affecting the parties to the Loan Documents or the transactions
contemplated thereby is valid and constitutional; (iv) all parties to the Loan
Documents will obtain all permits and governmental approvals required in the
future, and take all actions similarly required, relevant to the subsequent
consummation of any transaction among the parties to the Loan Documents or
relevant to the subsequent performance of any of the Loan Documents; and (v) the
Other Parties will act in accordance with, and will refrain from taking any
action which is inconsistent with, the terms and conditions of any of the Loan
Documents.

          (e) Our opinion is based upon and relies upon the current status of
law, and in all respects is subject to and may be limited by future legislation
or case law.

          (f) We have assumed that any interest under any Loan Documents will
not be charged, accrued or collected at a rate in excess of that permitted by
applicable law. Under the

SS&C Technologies, Inc.

laws of the State of New Jersey, a loan bearing interest at a rate in excess of
30% per annum with respect to an individual, a general partnership or a limited
partnership and in excess of 50% per annum with respect to a corporation, a
limited liability company or a limited liability partnership may be deemed
usurious and in violation of a criminal statute. For the purposes of this
opinion, we have assumed that the interest payable pursuant to the Loan
Documents will not, when calculated with respect to any period of time, exceed
the maximum applicable rate per annum that is deemed not to be usurious under
such criminal statute.

          (g) We have assumed that the resolutions authorizing and approving the
Loan Documents have not been amended, modified, supplemented or rescinded in any
manner since November 23, 2005.

     The opinions expressed herein represent our reasonable professional
judgment as to the matters of law addressed herein, based upon the facts
presented or assumed, and are not guarantees that a court will reach any
particular result.

     This opinion letter is limited to the matters stated herein, and no opinion
is implied or may be inferred beyond the matters expressly stated. This opinion
letter is given as of the date hereof, and we expressly disclaim any obligation
to update or supplement our opinions contained herein to reflect any facts or
circumstances that may hereafter come to our attention or any changes in laws
that may hereafter occur.

     We hereby consent to the filing of this opinion letter as Exhibit 5.3 to
the Registration Statement on Form S-4 (the "Registration Statement") filed by
the Company and the Guarantors with the Securities and Exchange Commission under
the Securities Act of 1933, as amended, and to the use of our name under the
caption "Validity of Securities" in the Prospectus included in the Registration
Statement.

     This opinion letter and the opinions contained herein may be relied on by
the Company, but, except to the extent specified in the immediately preceding
paragraph, may not be relied upon by any other person or entity without our
prior written consent and may not be used, circulated, furnished, quoted or
otherwise referred to for any other purpose without our prior written consent.

                                        Very truly yours,

                                        FOX ROTHSCHILD LLP
