Sometimes the design depends on the environment that it was developed for, whether it is created from reliable frameworks or implemented with suitable design patterns. When designing software, two important factors to consider are its security and usability. Developed by Therithal info, Chennai. Toggle navigation BrainKart.
Posted On : The nature of Design process Software design is the process of implementing software solutions to one or more set of problems. Related Topics Wireless Communication. Wireless Networks. There are many different kinds of software processes, but each and every one of them involve these four types of fundamental activities:. A software process model is an abstract representation of a process.
It presents a description of a process from some particular perspective. When we describe and discuss software processes, we usually talk about the activities in these processes such as specifying a data model, designing a user interface, etc. Process descriptions may also include:. Plan-driven processes are processes where all of the process activities are planned in advance and progress is measured against this plan.
In agile processes, planning is incremental and it is easier to change the process to reflect changing customer requirements. In practice, most practical processes include elements of both plan-driven and agile approaches. The software design process can be divided into the following three levels of phases of design: Interface Design Architectural Design Detailed Design Interface Design: Interface design is the specification of the interaction between a system and its environment.
Attention is focused on the dialogue between the target system and the users, devices, and other systems with which it interacts. The design problem statement produced during the problem analysis step should identify the people, other systems, and devices which are collectively called agents. Interface design should include the following details: Precise description of events in the environment, or messages from agents to which the system must respond.
Precise description of the events or messages that the system must produce. Specification on the data, and the formats of the data coming into and going out of the system. Specification of the ordering and timing relationships between incoming events or messages, and outgoing events or outputs.
Sometimes when, the system software area is characterized by the heavy interaction with computer hardware that requires scheduling, resource sharing, and sophisticated process management. Application Software: Application software is defined as programs that solve a specific business need. Application in this area process business or technical data in a way that facilitates business operation or management technical decision making. In addition to convention data processing application, application software is used to control business function in real time.
