What Tools can be used for Software Engineering and Development?
In the early 1970s, the data flow design method got created by Constantine and Yourdon. Concerning the flow of data, the data flow design is a functional decomposition. The input stream is transformed into the output stream by a component module. In a data flow diagram, there are four kinds of data entity that are data sources, data flows, processes, and external entities. Between the two processes, the data stores are present, whereas, the data flows between data stores, external entities, and processes.
The data is transformed by processes, whereas, the destination or source of a transaction is referred to as external entities. Further, a top-down decomposition procedure is involved in data flow diagrams. Only one process is maintained by the process at the highest level.
Collaborators, responsibility, and class are the initials that make up the CRC. With three fields labels index card is present in a CRC card. In response to the requirement for documenting the collaborative design decisions, the CRC cards were created. In the early phases of software development, the CRC cards help specify components informally, discussing the issues related to design in multi-disciplinary teams, helping in the identification of components, and the initial phases of software development. CRC cards are also considered as one of the low-technological tools. The elements that participate in a pattern are documented by CRC cards.
Moreover according to the perception of the modeling, one of the conceptual models of some part of an imaginary or real-world is the object. The object is a collection of three major aspects that are operations, variables, and identity or it can be behavior instead of operations and state in case of variables. The object-based is referred to as the programming language through which the types of abstract data are encapsulated in modules, whereas, inheritance is also supported by the adjective object-oriented.
Lastly, the component diagram, the communication diagram, the sequence diagram, the state machine diagram, and the class diagram are some of the major diagrams and tools that are used in the Unified Modelling Language. In the object-oriented analysis, the roots of the unified modeling language are present. The static structure of a system is depicted by class diagrams. Under the class diagram, the classes and their relationships and features are modeled.
Under the timing, the state changes of an object over time are modeled. Under the state machine, the states in which the transitions take place are modeled. The orders in which messages are exchanged between instances of classes are modeled under the sequence. Whereas the group of elements is modeled into packages under the package diagram and the in instance diagram (object), the objects and their relations are modeled.
The sequence diagrams and activity diagrams are combined under interaction overview, whereas, the physical layout is modeled under the deployment diagram. The internal dynamic structure of a class is modeled under the composite structure and a set of components and their interrelations are modeled under the component structure.
