  2. Advanced Query • Download the data file • Rename : YourLastName_inclass3

  3. Establish table relationships • Create appropriate relationships for the following tables. • Do not enforce referential integrity and do not enable cascade updates or cascade deletes. • AvgTempDiff and EPTData • HINT: The latitudes and longitudes have been set up to link the two tables together along with the date.

  4. Query A • Create a new query that lists all different fields from both the EPTDataand AvgTempDifftables. • Display the date, latitude, and longitude only once. • HINT:The query returns 48,340 records.

  5. Query B • Create a copy of Query A. • Use the YEAR() function to retrieve the corresponding value from the date. • Display only readings taken in the year 2003. • HINT:The query returns 4,320 records.

  6. Query C • Create a new query. Include all fields from Query A except the latitude and longitude fields. • Display the average by date for all data in the query. • Sort ascending by date. • HINT:The query returns 85 records.

  7. forms • A form is a database object that is used to add data into or edit data in a table. • Reasons to use forms : • You are less likely to edit the wrong record by mistake. • You can create a form that shows data from more than one table simultaneously. • You can create Access forms to match paper forms.
