Access Tutorial 1: Creating a Database
TRUE/FALSE
1. A collection of fields describing a person, a place, an object, an event, or an idea is a table.
ANS: T
2. A single set of field values within a table is a record.
ANS: T
3. A database is a collection of related tables.
ANS: T
4. A collection of related tables is called a relational database.
ANS: T
5. You connect the records in separate tables through a common field that appears in both tables.
ANS: T
6. A primary key in one table cannot be used as a foreign key in a different table.
ANS: F
7. Although a field has unique values in the table in which it is the primary key, it does not have to have unique values in the table in which it is the foreign key.
ANS: T
8. Like spreadsheets, a DBMS can handle massive amounts of data and can easily form relationships among multiple tables.
ANS: F
9. To start Access, click the Start button on the taskbar, click All Programs, click Microsoft Office, and then click Microsoft Office Access 2010.
ANS: T
10. The navigation buttons provide a way to move vertically through the records.
ANS: T
11. Query results automatically are stored in the database.
ANS: F
12. To restore a backup database file, you copy the backup from the drive on which it is stored to your hard drive, or whatever device you use to work in Access, and start working with the restored database file.
ANS: T
13. When designing a database, the first thing you should do is identify the fields that will be required.
ANS: T
14. Primary keys uniquely identify records in a table.
ANS: T
15. Every table defined in Access must have a single field that serves as its primary key.
ANS: F
16. A group of related fields is known as data redundancy.
ANS: F
17. A primary key that consists of more than one field is called a composite key.
ANS: T
18. Redundant fields waste storage space and can result in inconsistent data within the database.
ANS: T
19. A common field is a field that is defined as a primary key in one table and is defined as a foreign key in a second table.
ANS: T
20. A field in one table that establishes a relationship to another table is called a redundant field.
ANS: F
21. A field name must be unique within a database.
ANS: F
22. It’s best to choose a field or object name that describes the purpose or contents of the field or object so that later you can easily remember what the name represents.
ANS: T
23. A field defined as an AutoNumber data type cannot serve as a table’s primary key.
ANS: F
24. Certain Access data types have a predefined field size that cannot be changed.
ANS: T
25. The items marked 1 in the accompanying figure are the default property values for a Text field.
ANS: T
26. Click the item marked 3 in the accompanying figure to display a list of data types.
ANS: T
27. A primary key is allowed to have a null value.
ANS: F
MODIFIED TRUE/FALSE
1. Defining a(n) primary key in a second table creates a relationship between that table and the table where the primary key was first defined. _________________________
ANS: F, foreign
2. One benefit of a relational database management system is that it contains a built-in query language, which lets you obtain immediate answers to the questions you ask about your data. _________________________
ANS: T
3. A field name can consist of up to 255 characters. _________________________
ANS: F64sixty foursixty-four
4. The item marked 1 in the accompanying figure is the field selector. _________________________
ANS: F, 2
5. The field marked 2 in the accompanying figure is the record selector.
ANS: F, 1
6. Access has a button you can use to save the active database. _________________________
ANS: Tdoes not havedoesn’t have
7. The item marked 2 in the accompanying figure is the First record button. _________________________
ANS: F, 1
8. The item marked 3 in the accompanying figure is the Next record button. _________________________
ANS: T
9. The item marked 4 in the accompanying figure is the New (blank) record button. _________________________
ANS: F, 5
10. The data type determines what field values you can enter for the field and what other properties the field will have. _________________________
ANS: T
11. Access allows you to modify a table’s structure in Datasheet view. _________________________
ANS: F, Design
12. A(n) one-to-one relationship exists between the tables in the accompanying figure. _________________________
ANS: F, one-to-many
