Performance comparison for data storage - Db4o and MySQL databases

Choice of right and appropriate database is always crucial for any information system. Since database is an integral and important part, we choose to write the performance analysis of different type of databases in context to health care data. Health care database consists of Electronic Health Records. Also, various Electronic Health Record standards like HL7, openEHR and CEN EN 13606 have been defined for relational, object and object-relational databases. So far, none of the standard has been defined using object-database. In order to do so, we must compare and analyze the performance of object-database over others. In this paper, firstly we have studied the current trends in Indian Health Care with respect to medical data storage and retrieval. Next, we have compared the performance of MySQL (relational) and Db4o (object) database in terms of persistence time and storage space for a sample hospital data of 100 users.
