How can a database model implement versioning of data? Flags perhaps, though not the best solution. Meta data seems to be the key. Each table maintains the following meta data. DATE_CREATED, DATE_CANCELLED, DATE_UPDATED, DATE_EXPORTED, DATE_VALIDATED (The last two implement export functions telling us when data was exported and when this data was validated by some authority), DATE_START, DATE_END (Dates that indicate a period during which the date is valid).

Inserting a version :

DATE_CANCELLED is initialized to the end of time for us that is the 31st of December 9999.
DATE_CREATED and DATE_UPDATED are set to SYSTIME
DATE_EXPORTED, DATE_VALIDATED is initialized to the beginning of time for us that is the 1st of January 1972.

Deleting versions set DATE_CANCELLED and DATE_UPDATED to the system time.

Senario 1 : (DCR, DCA, DUP, DEX, DVA, DST, DEN are abriviations for the above meta data)

t0 t1 t2 t3 t4 t5 t6
|------------------------------------------------> Version one was inserted at time t1, so version one has the following values.

DCR, DCA, DUP, DEX, DVA, DST, DEN
t1, te, t1, tb, tb, t0, t6

Edit MyBlog

The xsi:type attribute of a complexType implies that the complexType has been extended to contain new properties. See Doing More With XML Schemas (part 1): "xsi:type"

This article recommends naming(typing) all xsd:complexTypes maximizing the ability to reuse the type. Doing More With XML Schemas (part 1)

Major flaws in software can be related to file location and syntax validation. Which is why XML was created.

I have been looking for cvs firewall and I just found it.
Access cvs using http proxy.
CVS from behind a firewall.
Of all places I found this on msdn.

My successful use of CVSGrab :

%CVSGRAB_HOME%\cvsgrab -rootUrl http://cvs.apache.org/viewcvs.cgi -packagePath xml-xmlbeans -destDir . -prune true -proxyHost 201.3.3.35 -proxyPort 8080 -proxyUser FR999925 -proxyPassword "lopign@"

The Comparable inteface requires that the compareTo(Object) method is implemented.

The difference between a Statement and a PreparedStatement is that the PreparedStatement is precompiled, therefore faster.

The Java Community Process(SM) Program - JSRs: Java Specification Requests - detail JSR# 107. I would really like this to be used in a Tomcat session cache.
