Modeling Principles for Software Project

-
Analysis Modelling Principles
  1. The information domain of a problem must be represented
  2. The functions that the software performs must be defined
  3. The behaviour of the software must be represented
  4. The models that depict information, function and behaviour must be partitioned is a manner that uncovers detail a layered or hierarchical fashion
  5. The analysis task should move from essential information toward implementation detail
Design Modelling Principles
  1. Design should be traceable to the analysis model
  2. Always consider the architecture of the system to be built
  3. Design of data is as important as design of processing functions
  4. Interface must be designed with care
  5. Component level design should be functionally independent
  6. Design representation should be easily understandable
  7. The design should be developed iteratively. With each iteration, the designer should strive for greater simplicity

Component Based Software Engineering

•Main characteristics –Makes intensive use of existing reusable components. –The focus is on integrating the components rather than on creating them from the scratch. •Advantages –Reduces considerably the software to be developed “in-house”. –Allows faster delivery. –In principle, more reliable systems, due to using previously tested components. •Disadvantages –agreement in requirements are needed. –Less control over the system’s evolution •Applicability: –When there is a pool of existing components that could satisfy the requirements of the new product. –Emerging trend: integration of web services from a range of suppliers.

What is Non-functional requirements

-
Image
These define system properties and constraints e.g. reliability, response time and storage requirements. Constraints are I/O device capability, system representations, etc. i.e. Deactivate or delete record after 24 hrs Process requirements may also be specified mandating a particular programming language or development method. Non-functional requirements may be more critical than functional requirements. If these are not met, the system may be useless. Types of Nonfunctional requirement Product requirement: Examples The MHC-PMS shall be available to all clinics during normal working hours (Mon–Fri, 0830–17.30). Downtime within normal working hours shall not exceed five seconds in any one day. Organizational requirement:  Examples Users of the MHC-PMS system shall authenticate themselves using their health authority identity card. External requirement:  Examples The system shall implement patient privacy. Non-functional requirements implementation Non-functional requirements may affec

Software engineering Ethics Issues of Professional Responsibility

-
•Confidentiality –Engineers should normally respect the confidentiality of their employers or clients irrespective of whether or not a formal confidentiality agreement has been signed. •Competence –Engineers should not misrepresent their level of competence. They should not knowingly accept work which is out with their competence. •Intellectual property rights –Engineers should be aware of local laws governing the use of intellectual property such as patents, copyright, etc. They should be careful to ensure that the intellectual property of employers and clients is protected. •Computer misuse –Software engineers should not use their technical skills to misuse other people’s computers. Computer misuse ranges from relatively trivial (game playing on an employer’s machine, say) to extremely serious (dissemination of viruses).
