(Foundations of) Architecture of Enterprise Applications

The notion of an architect as well as architecture of application systems is discussed. Based on this, the architectural diagrams and architecture description languages (ADLs) are introduced, and different architectural styles are discussed. Model-driven engineering of software is motivated. Non-functional properties are introduced and related to architectural modeling. Transactions are covered by discussing the ACID paradigm, concurrency control, and advanced transaction models. Synchronous as well as asynchronous communication is discussed along with RPC middleware and message queuing middleware. The concept of APIs is introduced. Based on the before, TP monitors as well as application servers are presented. A detailed discussion of high availability, scalability, stability, and consistency follows. Pattern languagesare introduced, and a first sketch of patterns of enterprise applications as well cloud computing patterns is given.
