Versioning Objects

Linked Help




In some cases an application may require that the objects being generated / processed will need to be versioned.  i.e. the object is modified into a second veresion of itself - not simply recreated as another object.

For example, if an object is to be updated as it passes through a process and the application needs to provide an audit trail of those modifications, then the object type should be set to be Versioned.  This is configured in Modeller and "understood" throughout the entirety of XPOR.


There are many cases where Versioning is necessary for a system.  You know the kind of thing, where a "proposal cost estimate" gets reviewed, edited, rejected, accepted, updated, reviewed etc.  Or a "Project Plan" is started, then revised, then ...

You will want to keep the source object (the "Proposal Cost Estimate" or "Project Plan") etc. as one object, just be able to save these changes as "versions" - and be able to switch to and fro between versions.

The example we have , a cost Estimate may be versioned, allowing the estimator to update the estimate, whilst maintaining the history / audit trail of the various versions.

Versioning Object Types

As suggested, versioning is applied to the Object Type - it is a simple check box setting in Object Modeller.  When selected the standard Object Versioning is enabled for that object type - all instances.

The attached video both demonstrates how this is enabled with Modeller and what affect Versioning has on the individual objects.
