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






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






3. 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.






4. 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






5. No partial functional-dependencies.






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






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






8. 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.






9. Dependency where determinant determines a list of values.






10. A link between two or more tables.






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






12. 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.






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






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






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






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






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






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






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






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






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






23. 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.






24. 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).






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






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






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






28. No multiple multi-valued dependencies.






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






30. The dominant database model






31. An abstract model that documents and organizes the business data for communication between team members and is used as a plan for developing applications - specifically how data is stored and accessed.






32. Attribute that determines the value of another attribute.






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






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






35. 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.






36. Functional dependency involving only non-key attributes.






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






38. 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






39. Arrange the records in a view set in order according to a particular field






40. 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.






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






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






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






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






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






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






47. 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.






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






49. a.k.a record






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