A test approach is the test strategy implementation of a project, defines how testing would be carried out. Test approach has two techniques:
aq
The main objectives of software engineering is that.- "The application of a systematic , disciplined quantifiable approach to the development, operation and maintenance of software.
IEEE gives software engineering definition as :-. The application of a systematic , disciplined quantifiable approach to the development, operation and maintenance of software that is the application of engineering to software.
1. The application of a systematic, disciplined, quantifiable approach to the development, operation and maintenance of software, that is, the application of engineering to software. 2. The study of the approaches as in (1).
We understand that every business is unique, so we take a personalized approach to design.

FTR's testing approach delivers a proven and repeatable testing process.
Software testing techniques are approaches you take towards running a test case. For example at the highest level you may take a black box approach or a white box approach to testing a piece of software. Where with a black box approach you don't understand the internals of the software you are testing but you do know what range of inputs the software can accept and from that you can deduce the expected results. With a white box approach you have a much better understanding of how the software works (perhaps you've been involved in a code review with the developers) and you can create your tests based on exercising the code knowing that the software should do x, y and z with the inputs. Software testing tools however would be employed to help you achieve the approaches you plan to take with testing a piece of software. So taking the black box testing approach discussed above you may use a test data generation tool to help you create the inputs for your black box testing technique. Another example would be using a data comparison test tool to compare expected results with actual results once the tests have been exercised. So in conclusion a test technique describes the approach you might take to test a piece of software, where as a software testing tool would be a method you employ to help you achieve the aims of the software test.
The three most common software development methods used by the Department of Defense (DoD) are the Waterfall Approach, the Incremental Approach, and Agile development. The Waterfall Approach is a linear and sequential model where each phase must be completed before the next begins, making it suitable for well-defined projects. The Incremental Approach allows for partial implementation and delivery of software in stages, enabling early testing and feedback. Agile development emphasizes flexibility, iterative progress, and collaboration, accommodating changes throughout the project lifecycle.
ya mca is software engineering. you will study database,java,.net,c,design and analysis etc during this course
search online for the book Software Engineering, A Practitioner's Approach by Roger s. Pressman..
CRM software is developed by many different developers, the best option would be to approach one of them. Try companies such as Jaythom, ProMax or Dealermax.
