Using the Application
Working with the database file
You must be comfortable creating a new database, opening an existing one, and saving it - including Save As to a different name or location, and understanding file formats (for example an older-version format versus the current one). Know where the navigation pane lists objects by type (tables, queries, forms, reports) and how to rename, copy, delete and close objects. Deleting a table is not the same as deleting the records inside it; closing an object is not the same as closing the application.
Entering and editing data
In a table datasheet you add a record, edit a field, and delete a record. Watch the record navigation controls: first, previous, next, last, and the new-record row. A frequent exam trap is the difference between undoing an edit to a field while still in that record and the fact that once you move to another record the change is committed. Another trap: a validation rule or required field may refuse the entry, and the fix is to correct the data, not to disable the rule.
Finding and housekeeping
Use Find/Replace to locate text quickly, and sort or filter to reorder or narrow what you see. Filters (by selection, by form) hide records temporarily; they do not delete them. Know how to print a table or datasheet, and how to preview before printing.
Rule of thumb
Edit, then move - but check first. Because leaving a record commits the change, verify the value before navigating away; if you have already moved on, use the record's undo or re-type the correct value.
Worked example
You must correct a misspelled city. Open the table, use Find to jump to the record, click the field, retype the city, then press Tab or click the next record to commit. To confirm, use Find again - the corrected spelling should now be the only match.
