Real-time computer systems are where the correctness of the system behavior depends not only on the logical results of the computations, but also on the physical instant at which these results are produced. What are the differences in the software engineering practices for Real-time software development over traditional application development?

Solution

Real time softwares are those that are developed for real time systems which require quick response time,very high reliability with negligible failure or downtime.hence the real time software should be perfect in operation and efficiency. In order to ensure that ,developers test the software in all possible ways of working during development so that it can be deployed on to the real time system directly so that no further maintenance is imposed during ite usage.

For example Operating systems for security systems which should work 365 days 24 by 7 without any downtime or efficiency glitches. Hence the process of real time software development is different as compared to traditional application development.

In case of real time all testing and quality assurance is done many times until the product is 99.9 percent efficient and then deployed into market. whereas in case of traditional application the process is requirement analysis followed by design followed by development followed by testing followed by deployment but the testing here is not complete.after deployment the users of product may report glitches or efficiency issues which may not be tested before and again they are fixed.

Example : application softwares like e-commerce web apps.
