Nowadays, database system technology is often used for handling information needed to be concurrently processed. The ability to support security control on the existing data is an important requirement in the database system. Thus, this paper is intended to study the concurrency control of the database system, especially on Two-Phase Locking Technique. This technique represented with an algorithm prevents conflicts among large amount of data in an application area, Car Ticket Reservation System. This implemented system is to provide the selling system through network as client/server model and each client is held by a user who is responsible for ticket selling function. The PHP programming language, Apache web server and MySQL database are used in this system.
