8th Grade Online Computer Test: Databases
Databases
|
| A | B |
|---|
| Ascending Order | Arrangement of data from lowest to highest in sequence. For example: A-Z or 1-9 |
| Database | A software application that helps manage large collections of information. A simple database might be a single file containing many records, with the same set of fields. Data can be sorted and searched by one or more criteria. |
| Descending Order | Arrangement of data from highest to lowest in sequence. For example: Z-A or 9-1. |
| Entry | Data that is keyed in a field. An example of an entry would be a phone number that is typed in a "phone number" field. |
| Field | A place in a database record where a category of information can be entered or located. |
| File | A set of related records in a database. |
| Record | A collection of related fields and entries. |
| Relationship | The comparison of two pieces of information using logical operators: less than (<), greater than (>), equals (=), less than or equal to (=<), greater than or equal to (=>). Other comparison terms to recognize are "at most," meaning less than or equal to, and "at least," which translates as greater than or equal to. |
| Search | The process of finding all records of a database that meet a certain rule, statement, or criterion. A search may be based on a single statement, rule, or criterion, or a combination of statements, rules, and criteria joined by AND, OR, and AND/OR. |
| Sort | Arranging information in a specific order (usually ascending and descending). Sorting a database does not eliminate any records; it simply rearranges the data in a different order. |
