3. Starter Play the whodunnit game to have a go at a database. www.cherwell.oxon.sch.uk/subjects/ict/whodunnit/

4. Objectives From the spec: “describe a database as a persistent organised store of data” “explain the use of data handling software to create, maintain and interrogate a database.” “describe methods of validating data as it is input” Learn the basics of databases ALL: Know what a database is (Grade D) MOST: Be able to explain record and field (Grade C/B) SOME: Be able to explore validation techniques (Grade A/A*)

5. The Brief A local doctor’s surgery require a system to store the details of their patients so that they know their contact details and basic medical details. They would also like to be able to set up appointments for patients and give a daily list to each of their doctors. The system will be used by the receptionist who is employed for her friendly personal skills rather than her IT skills so it should be user friendly.

6. Task Load Access. We are going to complete the first part of the brief by making a table to store the names and details of the patients of the doctor’s surgery. Design your own table. You should have at least 5 fields. 10 fields is better.

7. Robust Data? Try to ensure that people can’t enter inappropriate data by: 1.Choosing the correct data type 2.Adding an input mask 3.Changing the field size 4.Adding a lookup 5.Setting it to be required or not 6.Adding a default value to speed up data entry and to give people an example 7.Adding a validation rule

8. Mini-Plenary ALL: Know what a database is (Grade D) MOST: Be able to explain record and field (Grade C/B) SOME: Be able to explore validation techniques (Grade A/A*) Students will be PICKED ON to discuss their progress against these objectives

9. Data Entry records Add some records to your database in the table view. about 20 records You should aim for about 20 records. reflect on the quality of your validations, input masks and data types While you do this you should reflect on the quality of your validations, input masks and data types. You will be asked questions about this at the end of the lesson! FINISHED? Try some queries

10. Plenary Edmodo questions: 1.What is: a)A database? b)Field? c)Record? 2.Why might using an input mask of LL0 0LL for a postcode not be suitable for some customers? 3.Which is the most effective validation technique you have used and why?
