Object-oriented Analysis & Design using UML

A project is generally begun by analyzing the current situation in detail. This documents not only all applications and processes to be represented in the system, but also all the actors that interact with the system – whether people, processes and other systems. The so-called design model is used to model the professional entities and relationships and to describe all the requirements. All this is done independent of the specific technical implementation.

From design model to implementation model

In a further step, the design model is converted – using transformations – to a technical implementation model. This is now closely aligned with the technology used, such as the programming language and database. Using further transformation rules, the database schema and class structures are generated from the model with defined methods. This step can be repeated incrementally to save simple yet time-consuming development work and to avoid errors as well. The software developers then carry out the actual implementation as to the generated classes. This procedure – along with a test-driven approach – lets us create top-level software with a far lower error rate, so that you can use them soon and to your benefit.

Besides object-oriented analysis in software development, we also use UML for system analysis.
