Abstract

Due to the varying economic climate, organizations running Oracle are struggling to meet rising information demands with constricted budgets. Postgres significantly reduces total cost of database ownership, without sacrificing performance and scalability by eliminating up-front perpetual license fees. Why migrate at all? Either the current system has some functional flaws or its cost/benefit ratio does not appeal anymore to its owner. Three arguments are put forward in support of migrating to Open Source database management systems: Lowering Total Cost of Ownership (TCO), special features, and Open Source code. C-DAC's Hospital Management Information System "e-Sushrut" is a complete ERP solution for Hospitals or a chain of Hospitals. Commonly used technology in e-Sushrut is J2EE and proprietary database Oracle as backend. Organization has to pay certain amount to get license of oracle. Day by Day demand of health care services increase and it is not possible for all client to afford the cost of oracle's license. So by migration of database from Oracle to Postgres an effort is made to reduce database license cost as Postgres Community Edition is available free of cost.
