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






2. No partial functional-dependencies.






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






4. Refers to the number of associations that can exist between two record types.






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






6. The conditional expession that is to be used to select particular data records from a larger set of records.






7. 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






8. Relations which allow you to retrieve related records from the same table.






9. The set of fields in a table which stores unique values and so any one from the list can be selected to be the primary key.






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






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






12. 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.






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






14. 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.






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






16. 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.






17. No multiple multi-valued dependencies.






18. a.k.a record






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






20. 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.






21. The persons or things that a database table is about.






22. Candidate key selected for use.






23. A Key composed of more than one attribute.






24. A data type that is used for fields and calculations involving money






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






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






27. 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.






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






29. Table has no anomalies.






30. A field - set up in a query - that displays the result of an evaluated expression rather than displaying stored data.The value of the calculated field is re-calculated each time a value in the expression changes.






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






32. 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.






33. When a table is not only in 1NF but each non key field is functionally dependent on the full primary key






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






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






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






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






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






39. 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.






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






41. Guidelines set in place to ensure the trustworthiness of data over its entire life cycle.






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






43. An organised pool of related data files which can be easily accessed and managed and that may be used by a number of different application programs






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






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






46. 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.






47. The components of a data abase i.e. tables - queries - forms - reports - pages - macros and modules.






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






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






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