What Is the Data Dictionary?

The data dictionary is a binary file that captures the structure of the database, including tables, columns (representing fields) on the tables, indexes on the tables, and relationships between tables. The data dictionary files are binary-optimized forms of the product line definitions defined in LPL files.

File location: %LARUNDIR%\dict\dataarea.dict

The database dictionary is the source of the timestamp used to identify the data area directory (%LARUNDIR%\dataarea.timestamp).
