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 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.






2. DOC MADE UP






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






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






5. 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






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






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






8. The dominant database model






9. A database object on which you place controls for entering - displaying and editing records in a table.






10. 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.






11. Specialized engines designed specifically to store objects. Users can interact with objects only through designated methods.






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






13. A record as seen in the data sheet view.






14. A combination of attributes that can be used to uniquely identify a database record. Candidate keys are a special subset of super keys that do not have any extraneous information in them






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






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






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






18. One or more fields whose values uniquely identify each record in a table.






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






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






21. 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.






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






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






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






25. 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






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






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






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






29. A characteristic of the items in a database i.e. a field






30. Table has no anomalies.






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






32. The actual pieces of facts that are stored in the fields in a database table.






33. a.k.a record






34. 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.






35. 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.






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






37. A database object that prints information formatted and organised according to your specifications.






38. Functional dependency involving only non-key attributes.






39. No multiple multi-valued dependencies.






40. A graphical representation of any portion of a database scheme.






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






42. DBMS (Database Management System) statements used to manage data (tables and other objects) within a database






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






44. This is a property of data which - when satisfied - requires every value of one field (attribute) of a table to exist as a value of another field in another related table.






45. 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.






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






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






48. 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.






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






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