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






2. This is an exact numeric data type that holds from 10^38 - 1 through 10^38 - 1.






3. a.k.a record






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






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






6. 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).






7. A link between two or more tables.






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






9. No partial functional-dependencies.






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






11. 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






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






13. 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.






14. 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






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






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






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






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






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






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






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






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






23. Knowingly violates one or more rules of normalization.






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






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






26. Functional dependency involving only non-key attributes.






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






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






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






30. 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.






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






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






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






34. Data about data.






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






36. 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.






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






38. 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.






39. The process of examining and analyzing data with a view to extracting patterns from it. It is usually done on data warehouses






40. 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.






41. 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






42. 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.






43. A Key composed of more than one attribute.






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






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






46. The dominant database model






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






48. A control - also called an edit field - used on a form - report or data access page to display text or accept data entry.It can have a label attached to it.






49. 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.






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