ABSTRACT:
A method, system and article of manufacture for accessing data in a database independent of the particular manner in which the data is physically represented and for providing an abstract representation of the data in the database. One embodiment provides a method of architecting a logical representation of physical data in a database comprising providing a template data abstraction model defining template logical fields, and providing, on the basis of the template data abstraction model, a logical representation of the physical data, the logical representation defining a plurality of logical fields providing an abstract view of the physical data and adapted for transforming logical fields of abstract queries into a form consistent with the physical data in the database.
