CA VISION:Inform gives your database administrator the ability to present your corporate data, from multiple sources and formats, as a simple relational table to end users. We call this relational view of your data a virtual relational table, because it does not really exist in physical storage. It is created in memory at execution time.

Providing your end users with the capability to view data as a simple relational table not only simplifies the view of the data, but it also means that CA VISION:Inform can provide automatic processing of all occurrences and relationships that exist within the physical data.

Your database administrator can logically map your existing physical data structures into new logical data structures. This means that you are no longer limited by the constraints of your physical databases.

  • You can logically reorganize physical databases, as needed, regardless of the physical type and/or organization.

  • You can even customize and control which fields are accessible to a given set of users.

Data organization becomes a dynamic entity, rather than a static entity. You can dynamically manipulate this entity, as needed, to fit your changing business needs.

This means that you can treat the physical organization of your existing data as if it were a dynamic entity rather than a static one. You can use this unique CA VISION:Inform feature to solve your business problems in a more efficient and effective manner.

Being able to create new logical views of your existing data enables you to always use your data in a manner that is most convenient for solving the problem at hand.

  • Logical records provide a method for formulating a simpler conceptual view of a problem.

  • They provide independence from the physical structure of the data.

  • You can structure and organize the data in the way that you want to view it.

The view of the data corresponds to the problem you are trying to solve. This way, the problem rather than the physical organization of the data, becomes the driving force in developing an efficient solution. With the data organized in the same structure as the problem, solving the problem becomes trivial.
