The injector linac control system for SPring-8 is under development, and the first trial will be held this December for testing the total performance. We designed this system by object oriented methodology to integrate the operators' environment and the database architecture, and to keep easy maintainability. A disadvantage of the object oriented approach is a long lead time for abstraction, modeling and definitions of entities and relations. We represent the status of our software project management and the know how of rapid application development.
