Hi Christian,

You might want to search "business object" as well. Jim booth's book on OO Design covers them.

Also, there are three frameworks I know of that rely on them: Mere Mortals, Visual Fox Express, and Codebook.

There are two "thought current" when it comes to business objects:

The purist approach is that the business object is a direct representation of a record. Therefore the data is presented to the rest of the world as properties of the object.

The practical approach (that's how I call it) states that the business object is comprised pretty much as the "functionality" (fetch record, delete, add, etc.) and the data is still presented to the world as a cursor. The practicality of this approach is that it's faster (i.e. vfp loves cursors).

Mere Mortals uses the latter approach. Take Note's DataClass relies on the purist approach (under some circumstances it does return a cursor), but then DataClass, if I'm correct, is for interfacing with sql-server data rather than vfp dbf's.

Hope this helps!

Until now I used OOP for the benefits of having visible objects like forms and their controls or business classes and application control classes and so one, but for the code in those methods I handle the data still in a similar way I did in FP 2.6, with the exception of tablebuffering and the using of a database container.
