- Improved database integrity.
- The TPFDF product is easy to install and:
- Allows gradual migration from a traditional database
- Provides user exits for easy installation and migration.
- The TPFDF product is easy to use and includes:
- High-level assembler application macros

The TPFDF Distributed Data Access (TPFDF/DDA) optional feature lets you
propagate data from a TPFDF database to a DATABASE 2 database using structured
query language (SQL) statements. You can collect the SQL data from one
or more TPFDF files and from one or more fields in each file.
The database administrator must define (in the DBDEF macro) a file to use
the DDA feature. The data propagation is transparent to the TPFDF
application program.
See The TPFDF/Distributed Data Access (DDA) Feature for more information about the the TPFDF/DDA
feature.
The TPFDF product provides the following user exits that allow the
described functions:
- DFGDS
- To share TPFDF data with an MVS system.
- DFTDC
- To implement the dialogue control facility.
You can write the code to provide these functions or obtain the necessary
code from a third party.
