Overview

isCOBOL UDBC (Universal DataBase Connectivity) allows to integrate COBOL files into a relational database-like environment.

It enables you to apply SQL to your COBOL files resulting in data that is accessed and managed as in RDBMS systems.

Windows-based applications like Microsoft Office and Crystal Reports, applications developed in ODBC supported environments such as Visual Basic, and Java applications that use JDBC standards will be able to access your COBOL files.

This manual describes how to set up and configure isCOBOL UDBC databases and how to troubleshoot errors.

isCOBOL UDBC Architecture

The UDBC Server receives connections from SQL clients and provides them with access to COBOL files through the isCOBOL File Server. See isCOBOL File Server for more information on how to set up the isCOBOL File Server in order to allow remote access to files.

EFD dictionaries for each file are required. Compile COBOL programs with -efd option in order to obtain and EFD dictionary for each file described in the FILE SECTION.

The below picture summarizes how SQL clients access to COBOL files.
