A student has produced some work for a school project. A page of the work is shown. The Problem A Study of the English Wallaby Wild wallabies (Macropus rufogriseus) con nue to be reported across the whole of England. Despite the harsh winter condi ons, these animals have flourished in recent years. Many people have contacted the police with reported sigh ngs in gardens, quiet country lanes and even alongside busy motorways. The original colony, thought to be the source of the English wallaby, was first reported in Derbyshire in England. These animals were believed to have been released in the 1940s from a private zoo. It is more likely that other private zoos and escapees from wallaby farms are to blame. The Zoological Society of London keeps up-to-date records of private collec ons of wallabies in England, and to date there are over 100 such collec ons. Many people ask why it ma!ers if these animals have escaped, as they are not dangerous. The problem is that the introduc on of invasive, non- na ve species can have substan al impacts on na ve species, and wallabies are no excep on. The student has placed a column break in his document. Explain the purpose of setting a column break. 1 13 After running a spell check and proofreading his document the student notices that one word is still showing an error.

Mason is the head of a year group at a school. Every term he needs to send to parents a report on their child’s progress. This will include a written report and the percentage attendance over the term. Each term he loads the comments from his tutors into the word processing software. He then adds the attendance data from the database. The report is then printed and sent to parents. He has decided that in future he will use mail merge to print the reports. Give four advantages of using mail merge instead of typing the reports. As it is entered, the data on the database is checked using validation routines. The percentage attendance field uses a range check. Describe, using the percentage attendance field, the steps that need to be taken to create this validation routine. 1 13 Before the database can be implemented the validation routines need to be tested. Describe, using the percentage attendance field, how the validation routine will be tested by Mason.

For Examiner's Use 14 The head teacher of a school has employed Pierre, a systems analyst, to create a new database system to keep details of all students. Each student will be allocated a unique ten digit reference number. Pierre has written out some of the questions that the head teacher might ask. He can then analyse these in order to design a database which may answer these questions. Some are: Which year is Johann Schmidt in? (the school has students in years 7 to 13) Does Anita Nash have a sibling (brother or sister) in the school? Complete the data dictionary table below giving the field names which would be used in the database and identifying a validation check for each field. Field name Validation check Reference_number Year First_name None Explain the differences between verification and validation giving reasons why both are needed when data is entered into a database.
