Savannah River Site application design architecture

摘要

SRS applications development organizations are under pressure to increase system quality and productivity, achievable in large part from taking advantage of emerging computing technologies. Client /server (C/S), information warehouse (IW), and object orientation (OO) are three of the emerging technologies that are beginning to influence the development and delivery of computing systems. To effectively manage the information resources in a rapidly changing environment, SRS must be able to rapidly build dynamic computing systems, to quickly access reliable data, and to present information on a variety of platforms. This is accomplished through four key concepts: (1) data will be managed from a site perspective; (2) the reporting of information is separate from processes that collect and store data; (3) self contained applications must be replaced by modularized software solutions; (4) application developers will develop solutions based on a common tool set consisting of standard components, products, and services. The ADA describes a comprehensive vision and defines the direction which SRS should follow in the delivery of computing systems. It defines the structure within which technology will be employed, it defines a common approach to applications delivery that ensures consistency, and it defines the functions necessary to the delivery of information. The ADA represents a new approach for application development. Significant benefits of implementing the architecture include: (1) improved ease of use, productivity, and quality for the end-user; (2) more efficient use of computer resources, resulting in the reduction of overall costs; (3) improved functionality: GUI, multimedia, data integration and easier access to shared data; (4) increased competitive advantage from leveraging technology.
