Interfacing to Enterprise Resource Planning Systems

Today the darling application of the corporate IS shop is the ERP system. One of the things that was painfully (and expensively) pointed out to IS Managers over the last 3 years (Y2K preparation) was how terribly dependent corporations were on old legacy systems written 20 and 30 years ago in COBOL and PL/1. One of the options to becoming Y2K compliant was to move the corporate computing model away from the hodge-podge of legacy applications and databases that had grown up with the corporations that fostered them and toward a relatively standardized model that had been developed relatively recently under the guise of ERP systems.

ERP systems, like SAP, BAAN, and PeopleSoft, are based on a large database model of the entire corporation. After all, most corporations have a similar make-up (i.e., an accounting organization, accounts payable, accounts receivable, payroll, personnel, manufacturing, planning, etc.). If all these functions could share a common database and a common set of processes and procedures, the corporation could run more effectively and efficiently.
