Title: Water Billing System Database Design
Description:
Water Billing System is an application that will improve the business process and will promote quality service to the clientele. In this application, the developers used the client-server architecture in which multiple clients are connected to a single server that holds the central repository of records. As for the moment MS Access can still be used in a LAN setting.
The application will cover the following modules/features: (a) Client Module, (b) Installation and Disconnection Module, (c) Billing Module, (d) Payment Module, (e) Service Record Module, (f) Statement of Accounts, and (g) Report Generation. Visual Basic and MS Access are used to develop the project. The application has still rooms for improvement, for example, the future developers can convert the system into a web based version and add features like SMS notification.

tblaccount (id, username, password, fullname, contact, accounttype) – account table will store information on the different users of the system which includes the username, password and other personal information needed. The system can be accessed by the administrator will full access to the system, encoder accounts can only encode the client information and create new billing for the customers and the cashier accounts can only access payment module of the system.
