layout), with each row including a list of column or field names (vertical
layout) like a worksheet. Using database tables differs from using several
worksheets in a workbook. Generally, you will find it more natural and
beneficial to create additional tables than to create more worksheets. Also,
the rules for data consistency in any column are more strictly enforced in a
database, which helps you to improve the quality of the data that you are
Each field in the table can be of a different data type, depending on the
data to be held. Storing data in the correct field type is important because
you can take advantage of special features in the database—for example,
displaying a date picker when working with date data, or validating that
sensible data is being entered for the chosen field type, or relating the
data in one table to a list of values in another table.
A database normally consists of more than one table, and having the
tables correctly related to one another will save you a lot of subsequent
work. An invaluable tool in Access is the Lookup Wizard, which can
automatically build the required relationships between the tables.
