  1. Access Project 2 Vocabulary/Notes

  2. Query • A simple question represented in a way that Access can understand

  3. Select Query Window • The window is which you can create a query

  4. View Button • Button that tells Access to display the query results

  5. Text Data • Type the text in the criteria box below the corresponding field name • Criterion – A condition that the records to be included must satisfy

  6. Wildcards • Symbols that represent any character or combination of characters

  7. Asterisk Wildcard (*) • Represents any collection of characters • Example: • H* could stand for what names? • Henry • Hunter • Heidi • Harris

  8. Question Mark Wildcard • Represents any individual character • Example: • T?m could represent what? • Tim • Tom

  9. Parameter Value Query • A query that prompts the input whenever it is run

  10. Comparison Operators • Used when you want to enter a criterion that is not an exact match • > Greater than • < Less than • >= Greater than or equal to • <= Less than or equal to • NOT= Not equal to

  11. Compound Criterion • When you have more than one criterion in which the search must satisfy

  12. AND Criterion • Each individual criterion must be true in order for the compound to be true • Example: Find the clients that have an amount paid greater than $20,000 AND whose trainer number is 48.

  13. OR Criterion • Either criterion must be true • Example: Find the clients that have an amount paid greater than $20,000 OR whose trainer number is 48.

  14. Sort • The order of the results that are displayed • SORT KEY – the field or fields by which the records are sorted

  15. Sorting • Major Key – the more important sort field • Minor Key – the less important sort field

  16. Joining • Join – to find records in the two tables that have identical values in matching fields • Join Line – a line showing matching fields in the two tables indicating that the tables are related • Join Properties – are the properties that indicate which records appear in a join

  17. Property Sheet • The window containing the various properties of the object • The query property sheet is where you go to omit the duplicates in a query

  18. Top-Value Queries • Allows you to quantify results • Allows you to choose how many results you want to show (either the lowest or highest)

  19. Calculated Field • A field that can be computed from other fields • Use the ZOOM box • Every field name must be in its own set of brackets!

  20. Calculating Statistics • Aggregate Function – is a function that performs some mathematical function against a group of records

  21. Grouping • Creating groups of records that share some common characteristics • Example: Find the average amount paid for those clients that had Trainer #42
