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






2. No Transitive Dependencies.






3. 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.






4. 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.






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






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






7. A referential integrity constraint is a statement that limits the values of the foreign key to those already existing as primary key values in the corresponding table.






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






9. 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.






10. A query ( SQL statement ) that creates a new table and then creates records in it by coping records from an existing table.






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






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






13. a.k.a record






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






16. A value that may be assigned to an attribute when no other value applies or when the applicable value is unknown.






17. Knowingly violates one or more rules of normalization.






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






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






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






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






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






23. A link between two or more tables.






24. 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.






25. All determinants are candidate keys.






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






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






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






29. 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






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






31. 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.






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






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






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






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






36. 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.






37. 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.






38. Dependency where determinant determines a list of values.






39. 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.






40. 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.






41. DOC MADE UP






42. No multiple multi-valued dependencies.






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






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






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






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






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






48. 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






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