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.k.a record






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






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






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






5. A function such as sum - count or average that you use to include summary data in a report.






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






7. All determinants are candidate keys.






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






9. DOC MADE UP






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






11. A section of a record containing data relating to one single characteristic of an entity; also called an attribute






12. No multiple multi-valued dependencies.






13. 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.






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






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






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






17. A relation that contains no multivalued attributes.






18. A query that removes records which match the criteria you specify from one or more tables






19. 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.






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






21. 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.






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






23. No partial functional-dependencies.






24. 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.






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






26. 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






27. The dominant database model






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






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






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






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






32. 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.






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






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






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






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






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






38. No Transitive Dependencies.






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






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






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






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






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






44. 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.






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






46. Knowingly violates one or more rules of normalization.






47. 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






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






49. 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.






50. A Key composed of more than one attribute.
