Database Management System

Referencing Styles : Harvard 1.4.1 Volunteering Database Management System Implementation For this assignment you will be expected to use tables structure given to you, as a result of feedback on Phase Test tasks. This feedback will be available on the VLE, by week 7. Please read carefully the marking schema when doing your tasks. The following are the assessment tasks: 1) Implement four related tables and insert suitable test data. Also, create a view, based on your sub-system table(s). [20 marks] 2) Implement 3 suitable SQL statements (Apex Reports). To test your system, you are asked to produce a set of SQL statements (queries) which will be specified in plain English (business statement) and implemented. Your queries should be implemented as an APEX report, in the Application Builder. Your SQL statements will need to demonstrate appropriate complexity in order to achieve a high mark. You will be penalised when using Query Builder to complete the tasks. [30 marks] 3) Implement two triggers as procedural constraints to use within the Apex application. [20 marks] 4) Build appropriate APEX Forms/Pages to manage the data (insert/update/delete) of your sub-system. At least one page has to be master/detail. Consider including a home page, calendar, Reports, Charts etc. Higher marks will be awarded for applications which effectively utilise a good range of APEX functionality. [20 marks] 5) Create a User Guide for one of your Apex Pages and Reflection using the proforma, (see Appendix 2) [10 marks] Note: You can check with your tutor for the suitability of the reports/triggers/Apex features before you implement the code. 1.4.2 Deliverables Submit a single compressed file i.e. zip- not a rar file! The file should include: A document file with screen shots, evidencing where the code for the task is working successfully. (Where appropriate show evidence of code/application being tested. E.g. View images) A brief discussion of your implementation, for each screen shot have between 50-100 words. An export of the Apex Application (including tables (DDL and DML scripts), SQL code, PL/SQL code for triggers etc.). This assessment is assessed via a product demonstration during your tutorial session. You must upload your work to the VLE using the Assessment Template (found on VLE) for this submission, found on the VLE, by the deadline. Your uploaded work will be used for moderation purpose and by the External Examiner therefore providing evidence of your work is very important. If you do not attend the scheduled demonstration for the assessment, you will be given one further opportunity at a time which will be announced via the VLE. A 5% penalty will be applied to your mark for late demo. If you miss the late demonstration, your mark for the assignment will be recorded as Non-Submission and you will fail the module. 1.4.3 Preparation Guidance for the Demo There will normally be two tutors in the lab marking the work, but only one per student. In some cases two tutors will mark your work for moderation purposes. We suggest you demo your tasks in the order of 1, 2, 3 etc. to the marker. These are some sample questions your tutor may ask you during your demo session: o Explain/Show the table structure. What constraints have you implemented? o What data have you got on the tables? o Explain your SQL statement. What does the join part do? Why do we write a self-join query? o Show that you can insert, update and delete data from your master/detail form. o Why did you choose this Chart? How is it useful? What advanced features has your report got? o What advance Apex features have you implemented? You are being assessed on your understanding of your developed application and the underlying principles, NOT just your ability to navigate round it. Marks may be reduced due to poor understanding or explanation. Be ready to do the demo when the tutor approaches you. It is your responsibility to demonstrate your application in a way that provides evidence to your tutor that you have met the specification of the application, the marking criteria provided and have a good understanding of the subject. You are strongly advised to PRACTICE your demo, so that you make full use of the limited time. We realise that a maximum of 10 minutes may not seem much however, experience suggests that an application can be adequately demonstrated at this time if the demonstration is WELL PLANNED. 2 Assessment Marking Criteria Assignment 2 (60%) Student Name/Id: Tutor: Group: TOTAL: /100 Task 1 Out of 80+ 70-79 60-69 50-59 40-49 30-39 0-29 Tables, View and Data 20 In addition to previous: Sound mappings used of table designs to implementation stage.

There is clear evidence that the student has gone beyond syntax, functions, ways of testing the tables that has been taught in the class and module materials. Queries demonstrate advanced SQL structures. Use of CASE. Clearly considered Report presented to a high professional standard. In addition to previous: Well specified business rules for the query. SQL Statement based on the combination of intermediate and advanced level (necessary sub-query, functions (eg.
