Database selection is one of the main problems in designing electronic medical record (EMR) Software, since there are many different data with different types and formats in it. This work provides an approach for selecting suitable database management system (DBMS) with fuzzy analytical hierarchical process that gives capabilities of requirements to electronic medical record software. Criteria are choose based upon capabilities of requirements including supporting from type of operating system and programming language, maximum of table size, indexing, replication and access control. In addition, alternatives are PostgreSQL, MySQL, Oracle, DB2 and Microsoft SQL Server. According to the application of fuzzy analytical hierarchical process a ranking is obtained to decision making the best database management system for electronic medical record software.
