Central catalog that contains the descriptions of an organization's data and provides
information about the relationships between the data and its use in programs and screens.
The data descriptions in a Data Dictionary is also called metadata, i.e., data that
describes other data.
The ABAP/4 Dictionary stores system-wide data definitions. When you create a new data
definition, the Dictionary tool does all the processing necessary to create the definition.
You can use the Dictionary tool to look up the "definition" of objects in your R/3 System.
