Database schema extractor

Before compiling .4gl or .per files with Four Js Business Development Suite (BDS) or with Genero Business Development Language (BDS), you need to extract the database schema as a .sch file. However, the extraction tools differ.

BDS provides the fglschema tool, while Genero BDL provides the fgldbsch tool. The fglschema tool could only extract schemas from Informix® databases; the fgldbsch can extract database schemas from Informix, and from other databases like Oracle® DB, SQL Server, DB2®, PostgreSQL and Oracle MySQL.

The fglschema tool is still supported in Genero BDL for backward compatibility, but fglschema actually calls fgldbsch.
