    It can support a small clinic or hospital in managing patient personal, medical, and billing records through an easy to use Swing user interface. How to install: i. Simply import the database dump from the database folder to create the necessary tables for the system to run. You can use either phpMyAdmin for localhost; Microsoft SQL Server; or simply Query Browser for MySQL. Other database environments have not been tested hence I don't guarantee their adaptability. ii. Run and Build the system in NetBeans IDE 7.0. Other IDEs have not been tested for this system. A more stable and installable version will be released soon. iii. Please rate the system and leave comments or reviews. iv. If you need any further clarification, post a question/query/doubt in the Wiki and I will reply ASAP. NB: Please use the "External Link" menus above to support this project in one way or another. PM me for other means. Any kind of support will be very much appreciated. Thanks a bunch.
