ENTERPRISE INTEGRATION PROCESSING FOR MAINFRAME COBOL PROGRAMS

摘要

A method for facilitating a mainframe batch COBOL program to read from a cloud database is provided. The method includes receiving a first search predicate and a second search predicate from an extended language pre-compiler, the extended language pre-compiler parsing a user query written as a SQL query, building a cloud database format query based on the first search predicate and the second search predicate, transmitting the cloud database format query to the cloud database to extract data stored on the cloud database associated with the user query, and receiving the extracted data from the cloud database in a Java Script Object Notation (JSON) format.
