Rational Unified Process when developing large systems
Rational
Unified Process (RUP) is among the most recognized methods in the market
for reliable development of large and complex data systems. The data system will normally be modeled using the Unified Modeling
Language (UML) all the way from inception to delivery.The processes and the models ensure that requirements are
documented, communicated, modified and implemented in a structured manner
allowing full control during the life of the project. The data system will be constructed iteratively.
Each part of the system will be completed within a single step, the
next step commencing in parallell with possible refinements of the
previous one.
There are four phases in the RUP, called inception, elaboration, construction and transition, respectively. The inception phase establishes main goals and the framework for the project. The elaboration restructures functional requirements into UML use case models. Architecture, risk analysis and time planning are all taken into consideration in this step. The stepwise development belongs to the construction phase. Transition is delivery of the completed system. More on Rational Unified Process.
