The student mark processing system software has been developed and deployed at the st. peters university. the system shows the grade as 0 for all the students rather than the actual grade. which phase below was not done properly during the sdlc?

Examinations are an essential part of education and student lifecycle. They are the tools used to measure the success and effectiveness of the teaching processes and methodologies. Examinations are as stressful for the teachers and administrators for the student community, for different reasons. Students only need to worry about preparation and performance, whereas teachers and administrators have a lot to do on their part. Registration, test creation, security, evaluations, candidate verification and result tabulation are some of the important aspects of effective exam administration. Managing exams at a larger scale can be even more taxing. Traditional examination and result computation system involve huge volumes of answer-paper scripts that become difficult to manage and are vulnerable to risks that include damaged and misplaced answer scripts. The result system also requires manual sorting, evaluation and safeguarding, which contributes to the risk of errors and biases, security concerns and may ultimately cause delays in announcing the results. The solution lies in switching over to a digital and automated student result processing system from the current manual result processing system. Automated digital student mark analysis system are a real boon to educational institutions and testing bodies. From planning and preparing to evaluating, the student examination result processing system, in effect, frees up administrators and teachers who can focus their attention on...

“Students Attendance Management System” is software developed for maintaining the attendance of the student on the daily basis in the collage. Here the staffs, who are handling the subjects, will be responsible to mark the attendance of the students. Each staff will be given with a separate username and password based on the subject they handle. An accurate report based on the student attendance is generated here. This system will also help in evaluating attendance eligibility criteria of a student. Report of the student’s attendance on weekly and monthly basis is generated. — Over the years the manual attendance system has been carried across most of educational institutions. To overcome the problem of manual attendance, now we are using a web based attendance management system, which can be implemented on any computer. This system is being developed to maintain easy access of information from the database. The application makes use of MYSQL as back end and JAVA, HTML, CSS is used as front end. It tracks all the details of a student attendance from day one to end of the course. The conventional method of taking attendance by calling names or signing is very time consuming and insecure, hence inefficient and some of the reasons are not reported to the parents or guardians because the way of informing them is a traditional way and it takes a long process. Here, we implement a system which is SMS broadcasting, which will help the faculty to inform the parents about their stu...

The waterfall model is useful in situations where the project requirements are well-defined and the project goals are clear. It is often used for large-scale projects with long timelines, where there is little room for error and the project stakeholders need to have a high level of confidence in the outcome. Features of the Waterfall Model • Sequential Approach: The waterfall model involves a sequential approach to software development, where each phase of the project is completed before moving on to the next one. • Document-Driven: The waterfall model relies heavily on documentation to ensure that the project is well-defined and the project team is working towards a clear set of goals. • Quality Control: The waterfall model places a high emphasis on quality control and testing at each phase of the project, to ensure that the final product meets the requirements and expectations of the stakeholders. • Rigorous Planning: The waterfall model involves a rigorous planning process, where the project scope, timelines, and deliverables are carefully defined and monitored throughout the project lifecycle. Overall, the waterfall model is used in situations where there is a need for a highly structured and systematic approach to software development. It can be effective in ensuring that large, complex projects are completed on time and within budget, with a high level of quality and customer satisfaction. Phases of Classical Waterfall Model Waterfall Model is a classical software de...

The big picture Testing is intended to show that a program does what it is intended to do and to discover program defects before it is put into use. When you test software, you execute a program using artificial data. You check the results of the test run for errors, anomalies or information about the program's non-functional attributes. Testing can reveal the presence of errors, but NOT their absence. Testing is part of a more general verification and validation process, which also includes static validation techniques. Goals of software testing: • To demonstrate to the developer and the customer that the software meets its requirements. • Leads to validation testing: you expect the system to perform correctly using a given set of test cases that reflect the system's expected use. • A successful test shows that the system operates as intended. • To discover situations in which the behavior of the software is incorrect, undesirable or does not conform to its specification. • Leads to defect testing: the test cases are designed to expose defects; the test cases can be deliberately obscure and need not reflect how the system is normally used. • A successful test is a test that makes the system perform incorrectly and so exposes a defect in the system. Testing can be viewed as an input-output process: Verification and validation Testing is part of a broader process of software verification and validation (V & V). • Verification: Are we building the product right? The software...

Process modeling → Data objects are converted to achieve the business objective High-risk or major functions are addressed in the first cycles there by delivering an operational product. Which of the SDLC process models achieves this? High-risk or major functions are addressed in the first increment cycles and each release delivers an operational product Incremental model Beta technologies has undertaken a collision avoidance system software to be implemented for airports. Additional safety measures have to be automated by warning pilots when another aircraft gets closer, otherwise impacts are huge. Which of the following SDLC process models best suits the requirement? Spiral model is used when risks perceived is high Spiral model The student mark processing system software has been developed and deployed at the St. Peters university. The system shows the grade as 0 for all the students rather than the actual grade. Which phase below was not done properly during the SDLC? Software Testing Arrange the phases of Water fall model • Requirement Gathering • Analysis • Design • Implementation • Testing • Deployment • Maintenance Testing performed by the user to ensure that the system meets the agreed upon quality attributes and the specification is called as….
