Distributed Systems Application Development

Distributed application development takes a concurrent rather than sequential development approach, effectively using iteration to show progress and manage risk. This provides a basis for more rapid development, with smooth transitioning from one stage of a project to the next as well as continuous delivery of staged results that are of value in the total solution. The use of this approach implies iteration with a checkpoint at the conclusion of each stage to validate the quality of stage results, as well as the scope of the next stage. In addition to concurrency across stages, a release-based strategy ensures that there are short intervals between incremental releases of tangible results. This ensures that the direction of the project can be adjusted dynamically to accommodate critical events and needs.

Distributed systems outsourcing involves hosting Client/Server technology along with provision of system and network monitoring and administration services.

Distributed implementations are based on multiple levels of complexity, all of which are characterized by the distribution of processing logic. The choice of hardware architecture, development tools, and the development approach is influenced by the distribution strategy that results from the business requirements and system characteristics. Distributed development strategies are defined in terms of distributing presentation, function, and data access logic across the client and the server. The presentation layer handles the user interface and formatting information for display. The business object layer executes the business logic and is based on core business objects. The data access layer handles data-related processing.
