EDUC 210: Computers in Education

Database Handout

Definition Webopedia - A collection of information organized in such a way that a computer program can quickly select desired pieces of data. You can think of a database as an electronic filing system.

Tables in traditional databases are organized by fields, records, and files.

· Field - a single piece of information

· Record - one complete set of fields

· Table - a collection of records

For example, a telephone book is a table. It contains a list of records, one for each subscriber. Each of the records consists of three fields: name, address, and telephone number.

A simpler example may be to look at one of the databases that we have already done.

Each of the column headings is a field. Each row is a record. In databases we refer to columns as fields, and rows as records.

The most common database objects are tables, forms, queries, and reports.

· Table – collection of records

· Form – more user-friendly interface for entering information into the table

· Queries – used to pull only certain information from tables. We use criteria to tell the query what to pull, for example, only classes starting with CHEM.

· Report – a printer-friendly representation of information in a table or query.

IMPORTANT NOTES:

· Access has wizards for just about every object. Wizards make it easier for people new to Access to create objects such as tables, queries, forms and reports.

· It is important to know that each object has different Views.

· In design view, you can make any changes that you want to the structure and appearance of the object. For instance, in the design view for a form, you can move the data boxes around so that the page is more appealing. You can also change the background and the font, etc.

· In datasheet or form view, you can enter information directly into a table. In report view, you can see how your report is laid out.

· Access 2007 has made using databases much easier. The ribbon and wizards make using the database much more like creating a document in Word.
