I finished my essay！

Last night，I finished my essay named “The Design and Development of the Students' Management System”.
This System is designed by C/S architecture design.  Bulided by Built using MySQL databases，used Java to programming and referenced many Java classes. I used JDBC to connect Java and MySQL databases.
In this System，Users include teachers,、students and Administrators.  To increase the security, you should select identities in the main interface first.  Then different users use different functions.  Students just review messages, teachers can review and insert students messages.  The super identities is are Administrators，they can registation、register users, delete and modify users’ messages（including teachers and students）and the students‘ courses. In conclusion Administrators are awesome！

Notes: At least one space character follows the period character.

In this context Java is the proper name of a programming language and needs to be capitalized.

Very good.
