Using Access to Implement a Relational Database

2. Learning Objectives
Understand the Access objects, including tables, queries, forms, reports, pages, and macros.
Create, open and display tables based on the data model.
Create forms to enter data into tables.
Establish relationships among tables.

3. Access® Is a Microsoft DBMS program that
Defines the database;
Provides for simplified data entry;
Manipulates, stores, and retrieves data; and
Produces reports from the data.
Microsoft Access (Access) is a relational database management system.
Access refers to the structures used to manage the data as objects.

4. Types of Objects

5. Tables The most important object in a DBMS. Data is stored in tables.
A table is analogous to a file that stores/collects data.
All the data in a relational database are contained in various tables.

6. Queries
Allow the user to ask questions about the data stored in the database.
Can be used to locate and display a subset of the records of a table (called a “dynaset”).
Can be used to modify data by combining information from several tables into a single result, to perform calculations on fields, or to specify criteria for searching the data.

7. Forms Used to facilitate data entry.
Allow the user to see data from tables in another view, usually one record at a time.
Can be customized so that they are an exact copy of an existing paper form, making it easier to move from hard copy to soft copy.
In a fully automated setting, a form could be complete on-line at the time an event happens, greatly enhancing the simplicity and accuracy of data entry.

8. Reports
Utilize data created from queries and from one or more tables to provide the user with meaningful information in a printed format.
Can be produced by sorting, grouping and summarizing data.
Can be used to produce documents such as invoices, purchase orders, sales summaries, and financial statements.

9. Pages Also known as data access pages
Creates a Web-based form with the benefit of being able to handle live data from the Internet or an intranet outside of the Access database.

10. Marcos Are an advanced Access object.
Perform specific, user-specified, automated tasks, such as opening a form, printing a report, or going to the last record.
Can also assist in the creation of turnkey applications that anyone can use, regardless his/her level of experience with Access.

11. Modules Are an even more advanced Access object than Macros.
Can be used to create and edit Visual Basic code or procedures for the database.
Are the containers used to organize the code.
