1. IBM DB2 Universal Database For DataFlex Released in April 1999

2.  Supports main communication protocols Why IBM DB2 ?  Runs on a variety of Operating Systems  In the market since the early 1980s and current database market leader (in 1998 increased to a 32.3% market share) Server NT AIX HP-UX SCO Sun SCO Sun HP-UX AIX Windows NT Windows 9x Client TCP/IP NetBios IPX/SPX APPC Named Pipe

3. Benefits of DB2 For DataFlex  Combines the characteristics of a RDBMS with the power of DataFlex development tool  Offers an easy migration process – source code can be used with no changes  Widen the market for your DataFlex application

4. DB2 For DataFlex Elements  What you need to use DB2 for DataFlex with your application  DB2 UDB server 5 (or higher)  DB2 Client - CAE  DataFlex 3.1c (or higher) or Visual DataFlex 4.0c (or higher)  DataFlex Connectivity Kit for DB2 UDB

5.  Intermediate files (.int)  Conversion program (DataFlex 3.1x: drvr_cnv.flx; VDF: menu option) Connectivity Kit Components  Driver (db2_drv.dll) Contains the information the driver needs to access the converted files (information on server, user, database name, indexes, fields, configuration etc.) Converts the selected files into DB2 tables and creates the respective intermediate files Handles all application requests converting them into SQL statements

6. How conversion works Conversion Program + Driver Filelist.cfg Table INT Extension Delete DataFlex Files (Optional) Intermediate, FD and Log Files

7. Connecting to existing Tables  Step 1: Add a unique numeric identifier, if there is none already in the table  Step 2: Create an index file containing the identifier (one segment only)  Step 3: Create intermediate file using a text editor  Step 4: Make a new entry in the Filelist.cfg  Step 5: Generate a new FD file

8.  Running DataFlex applications with DB2 Running Applications Driver (db2_drv.dll) CAE INT Files Request Result SQL Request Result

9.  Some issues to remember Database Administration  DataFlex files are no longer used  Synchronicity between DataFlex or Visual DataFlex and DB2 needs to be maintained (INT files, FD files, etc.)  All business rules reside in DataFlex / Visual DataFlex (flexibility)
