Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The process of examining and analyzing data with a view to extracting patterns from it. It is usually done on data warehouses






2. Table has no anomalies.






3. The process of organizing data to minimize redundancy and produce smaller - well-structured relations/tables.






4. A value that is automatically entered in a field or control when you add a new record.






5. Groups of database commands which are to be treated as a single atomic event.






6. A link between two or more tables.






7. Attribute that determines the value of another attribute.






8. Knowingly violates one or more rules of normalization.






9. A central repository for databases across an entire enterprise.






10. Knowing the value of one attribute you can determine the value of another attribute.






11. A collection of fields that together describe one entity.






12. An association between two tables in which several records in one table can relate to 0 - 1 or many records in the other table.






13. A self-describing collection of integrated tables. The tables are called integrated because they store data about the relationships between the rows of data.






14. One (or more fields) in a table that refer to the primary key in another table.






15. A query that copies data or changes data in some way. This includes append - delete - make-table and update queries.






16. To modify a database - or the files associated with the database.






17. The window that appears when you open an Access database or an Access project. It displays the commands for creating new database objects and opening and manipulating existing objects.






18. Stored procedures that may be configured to automatically execute (fire) when certain events take place.






19. Two or more controls that can be treated as one unit while designing a form or report. You can select the group instead of selecting each individual control as you are arranging controls or assigning properties.






20. A normalization which falls between 3NF and 4NF and involves the elimination of non-trivial dependencies






21. Many-to-many relationships occur when each record in TableA may have 0 - 1 or many linked records in TableB and vice-versa.






22. The DBMS language component used to create - alter and destroy databases and database objects i.e. schemas - tables - views - sequences - catalogs - indexes - and aliases.






23. The program which is used to organize - access and manage the data in a database - Creates - processes - and administers databases.






24. A field in a table with unique values that although it is not the primary key - it could have been used as such.






25. An operator used to compare two values or expressions; For example - < (less than) - > (greater than) - = (equal to)






26. A location within a database table that stores one particular type of data i.e. a field






27. That structure which contains description of objects created by a user - such as base tables - views and constraints - as a part of a database.






28. Dependency where determinant determines a list of values.






29. A query that asks a question about the data stored in your tables and returns a results set in the form of a data sheet without changing the actual data in the table(s).






30. All determinants are candidate keys.






31. DOC MADE UP






32. A type of computer file system that stores all data in a single file.






33. The DML statement used to choose data from a database. The result is stored in a temporary table - called the result-set.






34. A control - also called an edit field - used on a form - report or data access page to display text or accept data entry.It can have a label attached to it.






35. The dominant database model






36. A programming language designed for managing & obtaining data in relational database management systems (RDBMS)






37. A database computer language designed for the retrieval and management of data in relational database management systems (RDBMS) - database schema creation and modification - and database object access control management.






38. A data model in which the data is organized into a tree-like structure. The structure allows representing information using parent/child relationships: each parent can have many children - but each child has only one parent






39. An MS Access tool that simplifies a task. For example - you can quickly create a complex expression with the Expression Builder.






40. A question about the data stored in your tables - or a request to perform an action on the data. A query can bring together data from multiple tables to serve as the source of data for a form. report or data access page.






41. The part of an SQL statement that specifies which record to retrieve.






42. Contents of a Database: Tables of user data - Metadata - Indexes - Stored Procedures - _______ - Security Data - Backup/Recovery Data






43. A characteristic of a field that determines what kind of data it can store and what type of operations can be performed on it.






44. No Transitive Dependencies.






45. In an access databse - a window in which you work with tables in design view or datasheet view.






46. A window that shows the design or structure of the database objects: tables - queries - forms - reports - macros and data access pages.






47. A table which is not only in 2NF but whose non-primary key fields are dependent only on the primary key and therefore have no dependence on (relationship to) any other non-primary key field in the table.






48. A primary key that is comprised of more than one field.






49. A relational database management system from Microsoft that combines the relational MS Jet Database Engine with a graphical user interface and software-development tools.






50. An association between two tables in which the primary key value of each record in the primary table corresponds to the value in the matching field or fields of one and only one record in the related table.
