Lecture 11 provides knowledge of shared data software architecture. An architecture style (also known as an “architecture pattern”) abstracts the common properties of a family of similar designs. Define a family of systems in terms of a pattern of its structural organization. | . These are differentiated by the flow control strategy. The data store in the repository architecture is passive, and clients of the data store are active; that is, clients (software components or agents) control the logic flow. Clients may access the repository interactively or by a batch transaction request. The repository style is widely used in database management systems, library information systems, the interface repository (IR) in CORBA, the UDDI registry for web services, compilers, and Computer Aided Software Engineering (CASE) environments. A well-known CASE tool is Rational Rose. It supports a graphic editor to draw UML diagrams, generates various programming code, and provides reverse engineering functionality to generate graphic diagrams from code. All Interactive Development Environments (IDE), and similar software development kits are good examples of application domains for the repository architecture. It is also widely used in complex information management systems where the most important issue is reliable data management.
