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






2. No Transitive Dependencies.






3. Candidate key selected for use.






4. A window that displays the SQL statement for the current query or is used to create a SQL specific query. When you create a query in design view - Access constructs the SQL equivalent in the SQL view.






5. All determinants are candidate keys.






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






7. All key attributes defined - attributes depend on key and no repeating groups.






8. The dominant database model






9. An attribute utilized to sort and/or identify data in some manner. Each table should have a primary key which uniquely identifies records.






10. A graphical representation of all entity relationships (Data Model)






11. A control that indicates whether an option is selected or not. A tick mark appears in the box when the option is selected.






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






13. Attribute that determines the value of another attribute.






14. A key that consists of 2 or more attributes that uniquely identify an entity occurrence.






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






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






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






18. 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.






19. A graphical representation of entities and their relationship to each other - typically used in computing in regard to the organization of data within databases or information systems






20. Data from a table - form - query which is displayed in a row-and-column format.






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






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






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






24. When a relation is not just in Boyce-Codd Normal Form - but also contains at most one multivalued dependency.






25. A query that displays a summary calculation - such as an average or a sum - for values in a table or tables. A totals query is not a seperate kind of query; rather it extends the flexibility of select queries.






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






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






28. A link between two or more tables.






29. A feature that speeds up searching and sorting in a table based on key values and can enforce uniqueness on the rows of a table.






30. A database object that stores data in records and fields. The data is usually about a particular category of things.






31. An association/link established between common fields in two different tables. A relationship can be one-to-one - many-to-many or more usually one-to-many.






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






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






34. 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).






35. A way of looking at a database object - usually looking at the design or at the contents/results






36. A candidate key that coud have been the primary key but was not selected as such ; OR a field that is not the primary key but has been used for indexing nevertheless.






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






38. 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.






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






40. The horizontal bar at the top of a column. You can click a column selector to select the entire column in the query design grid or the filter design grid






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






42. 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.






43. An action query that adds the records in a query's result set to the end of an existing table.






44. 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 of0 - 1 - or many records in the related table.






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






46. 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.






47. 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.






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






49. A field data type that automatically stores a unique number for each record as it is added to a table.






50. A DBMS created by Microsoft - it is a collection of data and objects - such as tables - queries - or forms - related to a particular topic or purpose.
