System Design and Architecture

  1. System Design and Architecture
Just as an architectural design is important in erecting a building structure, building an efficient software application that will meet the requirement and serve the intended purpose also requires a good system architectural design. To help ensure that your software system or application meets your users' needs, a good model must be created as part of your description of the overall structure and behaviour of your software system or application. Using models, you can also describe patterns that are used throughout the design. These models help you understand the existing architecture, discuss changes, and communicate your intentions clearly.

The purpose of a model is to reduce the ambiguities that occur in natural-language descriptions, and to help in visualizing the design and in discussing alternative designs. A model should be used together with other documents or discussions. By itself, a model does not represent a complete specification of the architecture. A model also gives the designer a good direction during his development process.

In designing system architecture, the system to be designed must first be understood, this requires a serious requirement gathering which describes the intention of the system. Standard system architecture with the aid of UML diagrams and use cases should encompass the following stages:

  • User requirement gathering
  • Architectural patterns
  • Component and their interfaces (with the aid of UMLdiagrams)
  • Dependencies between components
  • Interfaces to decomposing a component into parts
  • Interaction between components
  • Identifying the initiating events
  • Computations description
  • Operations specification
  • Data model of components and interfaces
  • Design patterns
With the dynamics of our young but intelligent, solution savvy made up team of system architects who understand the rudiment of both high level design and design patterns, we at BVS can help in designing best fit solutions that will serve your business needs better. Further system integration can also be achieved to also optimize the use of an existing system that are currently running, but not at full capacity.
