This book describes how to use the Database Connectors interface to access relational database management systems from COBOL.
Database Connectors Overview
This chapter provides an overview of Micro Focus Database Connectors and how you can use its interfaces to bridge the worlds of COBOL and Structured Query Language (SQL).
Using XFD Directives
This chapter explains what XFD directives are and how you can use them in your COBOL File Descriptors (FDs) to control how your database tables are built.
Invalid Data
This chapter lists which COBOL data items are considered invalid and explains what happens to them when they are stored in the database. It also explains which database items are considered invalid and explains how these are translated to COBOL.
New and Existing Databases
This chapter tells you how to handle your data in both existing and new databases.
Run-time Configuration
Database Connectors™ uses an ACUFH configuration file to determine how the run-time system should behave when interacting with data. This chapter describes the ACUFH configuration variable options that you can use to configure the run-time system for your relational database environment.
General Questions and Answers
