SDL Definition
(Specification and Description Language) A modeling language used to describe real time systems. It is widely used to model state machines in the telecommunications, aviation, automotive and medical industries. SDL is used to model the details of a system, which can be simulated and proven, whereas UML is used to model at a higher level of abstraction. There are three parts to an SDL diagram: the system definition, block and process. The system definition defines the major nodes (blocks) of the system such as clients and servers, while the block charts show more details. The process diagram shows the processing steps in each block. System diagram shows how a component (the system) is composed by different other components (blocks). The static communication paths (channels) between the components are shown as well as the signals that can be sent on the channels. Process diagram defines the dynamic behavior of a component (process or process type). It contains a number of states and transitions between the states that carry out the state-dependent behavior. SDL Shapes Create object-oriented diagrams for communications and telecommunications systems and networks, using Specification and Description Language (SDL). Based on CCITT specifications.
