12 Ipt Database Reports Presentation Transcript

  • 1. Database Reports Information Systems and Databases – Year 12 IPT
  • 2. Other processes and issues for information systems
    • Most DBMS programs create neat reports
    • The standard method of DISPLAY in in rows and columns
    • Useful for checking data/information
    • Can be FULLY FORMATTED with headings and layout or SIMPLY FORMATTED with just raw looking data
  • 3. SIMPLE PAYSLIP REPORT – Little Formatting applied to it.
  • 4. Other processes and issues for information systems
    • Report generators use WIZARDS to take you step by step through the process of creating a customised report.
    • Report Generators let you customise the design – including;
    • Margins, Headers, Footers, Colour, Style
    • DBMS = DATABASE MANAGEMENT SOFTWARE….remember it and USE IT.
  • 5. Pre-IPT Reporting
    • Reports we’re pre-printed – STATIC information was produced.
    • People either typed or hand wrote information onto the report, the DYNAMIC information
    • DYMANIC – of an expected data type BUT usually un-predictable data.
    • People CALCULATED the results
  • 6.  
  • 7. Layout and Design
    • To create a report, layout is designed showing where the different features will be placed.
    • These features include;
    • STATIC FIELDS – items not taken from the DBMS – headings, page numbers, notes
    • DYNAMIC FIELDS – data appears by extracting it from the DBMS
  • 8. Design and Layout
    • Calculated Fields – these fields are produced by PROCESSING data.
    • Subtotals, Average, Minimum Maximum
    • Databases ‘views’ – ie how you look at the information is usually by a SINGLE record (often the default). You press to advance or go back.
    • You can put several ‘views’ on a page – to create ‘information’.
  • 9.  
  • 10. Issues related to DBMS
    • Data Source
    • The origin of the ‘raw’ data to be used by the DBMS to achieve some information proccessing purpose.
    • Accuracy
    • Methods used to ensure that data entered is as accurate as possible.
    • Completeness
    • Data is sufficient for the DBMS to proccess, analyse and/or display information accurately.
  • 11. Answer the following
    • Compare and contrast data verification and data integrity when considering the data and information people and organisations keep on might not be verified leading to a us experiencing difficulties with a bank loan in the future.
    • Highlight the question type.
    • Identify the two concepts we are comparing?
    • Identify the word that gives us the syllabus ‘context’ to answer this question?
