The Data Model

A conceptual description of data objects, their attributes, and the relationships between them.

There are different types of data models, depending on the data structures to be defined such as relational data model.

Repository

A repository is a place, room, or container where something is deposited or stored.

An information tool that stores details about all development objects in the R/3 System and their relationships.

The user interface of the R/3 Repository Information System resembles a file manager where objects are grouped together in object categories within a hierarchical structure.

In the R/3 Repository Information System, you can:

Generate lists of programs, tables, fields, data elements, and domains

Determine where certain tables and fields are used on screens and in ABAP programs

Display foreign key dependencies

Data Modeling

Purpose

The Data Modeling IT process allows you to model various InfoProviders. These InfoProviders include InfoObjects, DataStore objects, InfoCubes, VirtualProviders, InfoSets and MultiProviders.

If you have modified the structures in an operational system, you can use remodeling to adapt these data models to the changes.
