Access Module 3: Maintaining a Database

अब Quizwiz के साथ अपने होमवर्क और परीक्षाओं को एस करें!

Split form

Database form that allows you to simultaneously view both simple form and datasheet views of the data.

Action query

Query that adds, deletes, or changes data in a table.

Make-table query

Query that allows you to add query results to a new table.

Append query

Query that allows you to add the results of a query to an existing table.

Delete query

Query that allows you to delete all the records satisfying some criterion.

Update query

Query that allows you to make the same change to all records satisfying some criterion.

Filter

Sorting method that allows you to find only the record or records that satisfy specific criterion.

Format symbol

Special symbol that determines a field's appearance.

How Do You Determine Whether to Use a Query or a Filter?

- If you think that you will frequently want to display records that satisfy this exact criterion, you should consider creating a query whose results only contain the records that satisfy the criterion. To display those records in the future, simply open the query. - If you are viewing data in a datasheet or form and decide you want to restrict the records to be included, it is easier to create a filter than a query. You can create and use the filter while you are viewing the data. - If you have created a filter that you would like to be able to use again, you can save the filter as a query.

Once You Have Decided to Use a Filter, How Do You Determine Which Type of Filter to Use?

- If your criterion for filtering is that the value in a particular field matches or does not match a certain specific value, you can use Filter By Selection. - If your criterion only involves a single field but is more complex (for example, the criterion specifies that the value in the field begins with a certain collection of letters) you can use a common filter. - If your criterion involves more than one field, use Filter By Form. - If your criterion involves more than a single And or Or, or if it involves sorting, you will probably find it simpler to use Advanced Filter/Sort.

What Kind of Decisions Should I Make in Determining Whether to Change the Format of a Datasheet?

- Would totals or other calculations be useful in the datasheet? If so, include the Total row and select the appropriate computations. - Would another gridline style make the datasheet more useful? If so, change to the desired gridlines. - Would alternating colors in the rows make them easier to read? If so, change the alternate fill color. - Would a different font and/or font color make the text stand out better? If so, change the font color and/or the font. - Is the font size appropriate? Can you see enough data at one time on the screen and yet have the data be readable? If not, change the font size to an appropriate value. - Is the column spacing appropriate? Are some columns wider than they need to be? Do some columns not display all the data? Change the column sizes as necessary.
