Gold Unit 11 – Database Software 1. Create and modify non-relational database tables 1.1 I can identify the components of a database design See database 1.2 I can describe the field characteristics for the data required Name of field Data type If text – length required Reason for choice of Data Type Choice field – if yes, list the choices Would an ‘input mask’ help? (An input mask allows a preset layout, e. g. for national insurance numbers, post codes, phone fields.) If number – type required. Decimal places needed? Title Text 5 It is a text a only uses letters I only used 5 letters for a tittle because not many common titles have over 5 characters Yes Surname Text 25 It uses only No letters and all surnames are under 25 characters long. An input mask would not help as a set layout would not work as each option is a different format e.g. different amounts of text. An input mask would not help as a set layout would not work as each option Primary Key Yes / No no No Initial Text 1 Address 1 Text 40 Address 2 Text 20 It is a text a only uses letters I only used 1 letters for an initial because not many common titles have over 1 characters It is a text a only uses letters I only used 40 letters for an address line 1 because not many common titles have over 40 characters It is a text a only uses letters I only used 1 letters for an address line 2 because not many common No No No is a different format e.g. different amounts of text. An input mask would not help as a set layout would not work as each option is a different format. An input mask would not help as a set layout would not work as each option is a different format e.g. different amounts of text. An input mask would not help as a set layout would not work as each option is a different format. No No No Town Text 20 Postcode Text 10 Home Phone Text 15 Mobile No Text 15 titles have over 1 characters It uses only letters and all towns names are under 20 characters long. No It uses only Yes letters and numbers and this option is suitable for them both. All postcodes are under 10 characters long. It uses only No numbers and all home phone numbers are under 15 characters long. It uses only No different amounts of text. An input mask would not help as a set layout would not work as each option is a different format e.g. different amounts of text. It would help as a postcode is always in the same layout so this would be suitable. No No An input No may help but in the input mask mobile numbers you have the first bit in brackets and you do not write a mobile number in this format. It would Yes numbers and all mobile phone numbers are under 15 characters long. Phone Purchased Text Date of Purchase Price Plan 20 It uses only letters and all phone names are under 20 characters long. No Date/Time Short date It is the best option for inputting dates. No Text It uses only letters and all price plan names are under 15 characters long. Yes 15 work as it would be in the correct format but some are ex-directory and these would not be able to be inputted in to the filed. An input No mask would not help as a set layout would not work as each option is a different format e.g. different amounts of text. The date No text type already has an inbuilt input mask so one is not needed. An input No mask would not help as a set layout would not work as each option is a different format. different amounts of text 1.3 I can create and modify database tables using a range of field types See database 1.4 I can describe ways to maintain data integrity To maintain the data integrity I have used combo boxes using the look up wizard for the customer’s title and their price plan. This will mean that there will be spelling mistakes in that filed. I have also used an input mask in the postcode field. This will mean that the information in that field will be consistent. This will mean that it will all be in the correct format. I have also used an input mask in the date field. This will ensure consistency with the format. The format I chose was short date. This will be entered as DD/MM/YYYY. I also set the mobile phone number as the primary key. This is so this data can only be entered once into this field. This will mean that no customers will have the same phone number as 2 people can never have the same phone number. This will ensure that this mistake will not be made. 1.5 I can respond appropriately to problems with database tables See database 1.6 I can use database tools and techniques to ensure data integrity is maintained See database 2. Enter, edit and organise structured information in a database 2.1 I can create forms to enter, edit and organise data in a database See database 2.2 I can select and use appropriate tools and techniques to format data entry forms See database 2.3 I can check data entry meets needs, using IT tools and making corrections as necessary See database 2.4 I can respond appropriately to data entry errors See database 3. Use database software tools to run queries and produce reports 3.1 I can create and run database queries using multiple criteria to display or amend selected data See database 3.2 I can plan and produce database reports from a single table non-relational database See database 3.3 I can select and use appropriate tools and techniques to format database reports See database 3.4 I can check reports meet needs, using IT tools and making corrections as necessary See database
