Rota system A system that stores information about employee availability and shifts that employees are needed for at a business and matches these two together would be of A-level standard, presuming that it was the program that carried out the matching process and not the user.

Ideally, the tests completed should show that the system developed has fulfilled its purpose and demonstrates to the assessor the scope of the final system. For example, if a simulation is produced, the whole purpose of the system might be to see what happens under certain conditions and testing the core processing functions of the project would involve experimentation. Some of this feedback could be generated during prototyping. Design: Description of measures planned for system security vi. They should be encouraged to carry out further relevant research and after consultation with their teacher, refine and reassess their initial objectives as appropriate. An error has occurred while processing your request. If a student has not produced a suitable set of objectives in the analysis, then this mark should be awarded on the basis of what the assessor believes a reasonable set of objectives for the project would have been. The third party might be a potential user of the software, such as a friend, relative, employee or teacher or somebody with knowledge, interest or expertise in the problem area. No independent feedback obtained or if obtained is not sufficiently useful or realistic to be evaluated in a meaningfully way even if attempted. This is particularly pertinent if students choose two texts from the same genre poetry, prose, drama.

Queries If a project uses a database, samples of the queries that are used, together with explanations should be provided. Testing does not all need to be carried out on the final version of the system. Prototyping and critical path Prototyping the critical path at the analysis stage, early in the project development period, is encouraged so that changing objectives later on occurs only in exceptional circumstances, and with the agreement of the teacher.

In accordance with JCQ guidance, mark coursework practical would not be acceptable:. In accordance with JCQ guidance, scheme following support would not be acceptable: Awarding marks The role and responsibilities of teachers in practical marks are set out in Section 6.

The teacher could ask students to write notes to point out where in their program code they have used particular techniques.

However, this judgement could be assisted by other evidence: The documented design should include evidence of the data structures and algorithms the student intended to use. It doesn't have to be incredibly complicated, but you need a degree of complexity in order to write a good report.

This in turn allows the student to identify the objectives for the project, giving a clear purpose and direction for their design and solution development. Sections 4.

Therefore, evidence of HCI can be presented as explained screenshots rather than hand-drawn or package-drawn plans.

A point in time should be reached when the agreed set of objectives is frozen. For students, design is also an opportunity to convey the level of technical complexity of their solution. Please enable JavaScript. Sequencing It is often useful to complete some elements of the design, such as planning data structures, before coding takes place. No independent feedback obtained or if obtained is not sufficiently useful or realistic to be evaluated in a meaningfully way even if attempted. In doing so, she will express her ideas using appropriate terminology. For example, if a simulation is produced, the whole purpose of the system might be to see what happens under certain conditions and testing the core processing functions of the project would involve experimentation. Database design If a project stores data in a database, the structure of the tables should be described and an entity-relationship diagram could be used to show how the tables are related. Exemplar student responses accompany this guidance. The actual feedback obtained from the third party should be included in an appendix. Other elements of the design that would be useful for maintenance could have their design documented after they have been coded. Methods and sources Students should be encouraged to use a range of appropriate methods and sources to research and investigate the problem, including websites, existing software, books, interviews, questionnaires, prototyping.

The emphasis is on communicating the design; therefore it is acceptable to provide a description of the design in a combination of diagrams and prose as appropriate, as well as a description of algorithms, SQL, data structures, database relations as appropriate, and using relevant technical description languages, such as pseudo-code.

Design: Overall test strategy This chapter aims to give you the skills to complete your A2 Computing project.

A level programming

For technical solution, you should have already taken the standard into account for this, by directly applying the criteria. How the outcome could be improved if the problem was revisited is discussed but consideration given is limited. The incorporation of a code-cracking option that used techniques such as frequency analysis or comparing potential solutions to dictionary text to crack a code would offer access to higher marks for the technical solution, as a result of more complex algorithms being used. These approaches are equally valid and take mark of practical different contexts in which schools and project will be working. No independent feedback obtained or if obtained is so basic as to be not worthy of evaluation. Possible items that might be present in design could be: Algorithms Processing of data should be at the heart of all projects. Schools and colleges may aim to introduce the NEA in the first year of the course.
