Basis data terdistribusi yang datanya tersebar di beberapa lokasi sangat rentan terhadap inkonsistensi data. Kontrol konkurensi berfungsi untuk mengurangi terjadinya konflik proses pada suatu basis data. Pada tesis ini, penulis memanfaatkan tool Interbase sebagai DBMS yang men-support kontrol konkurensi. Mekanisme Explicit Locking digunakan meningkatkan kemampuan Interbase dalam menjaga data dari dampakdampak update konkuren seperti deadlock. Penulis mensimulasikan kontrol konkurensi pada Shopping Cart dimana transaksi dilakukan melalui internet.

Distributed database which has data stored on several locations is weak over data inconsistency. Concurrency control is aimed at decreasing the conflict that might be happen while processing of the database. In this thesis the writer uses Interbase tool which concurrency support. Explicit Locking mechanism is used increase its ability to prevent data from the effects of update concurrent such as deadlock. The write simulate concurrency control in Shopping Chart in which the transaction did through internet.
