Mainframe COBOL to Java, C# & Cloud

UNISYS MCP and Burroughs COBOL to Java / C# Conversion

UNISYS's dialect of COBOL closely adheres to ANSI COBOL 74/85 standards. However, it includes several unique extensions such as advanced COBOL language features, screen definitions, and integration with DBMS, DMS database systems, and APIs.

Handling DMS, DMS-II, or DMS-2000

Unisys COBOL programs often utilize DMS, DMS-II, or DMS-2000 database systems and their associated APIs.

The first step in SoftwareMining's migration process involves parsing the DMS database schemas using our translator. This process generates COBOL copybooks that represent the Data-Sets.

These copybooks are then utilized by the COBOL to Java/C# Converter to produce:

• SQL Schema: The new tables mirror the fields defined in the original database schemas.
• Object-Relational Data Access Objects (DAOs): Translated programs access the SQL tables through these DAO classes.

For instance, a record named INVOICE-RECORD will be converted into an SQL table called INVOICE_TABLE, containing all the fields defined in the COBOL structure. Additionally, an Object-Relational class, InvoiceClass, will be generated to handle database communication between the translated application and the SQL database.

The API simplifies database access through statements like CREATE, STORE, LOCK, FIND, and SELECT, ensuring efficient interaction with the new database.

Furthermore, additional UNISYS-specific APIs will be supported through SoftwareMining libraries, ensuring seamless integration and compatibility.
