- 5. FactoryAccess Accel. Introduction v1.025 But first - Create Folder Create a folder yourname (or similar) in My Documents – this is where your database and other files will go. Optionally, copy in the labor.txt and employees.xls files from the instructor supplied location or CD.
- 6. FactoryAccess Accel. Introduction v1.026 Access Modes Menu-driven interface - Interact with a database and its objects using menu commands Program mode - Lets you store instructions in a VBA program file This course concentrates on the menu interface but does cover macros which can be used to “program” a series of actions
- 7. FactoryAccess Accel. Introduction v1.027 Database Terminology Database – in Access a repository in which tables, reports, queries, and other objects are stored Table – stores facts about one subject (entity) Record - contains related information about an entity “instance” Field - contains a fact about an entity Relational Database - allows you to link records from two or more tables based on the contents of a common field.

Table structure - the arrangement of information within a record, the type of characters, field length, limitations, etc.
- 9. FactoryAccess Accel. Introduction v1.029 Database Terminology (cont.) Object – used in database world as generic term for queries, reports, indexes, tables, etc. Not the same as programming object. Form - paper-like method of accessing and entering data in a table Query – retrieves information from Access tables Report - provides the ability to arrange table data as well as to perform calculations and then print a paper-based report
