A database is a program that allows easy access, retrieval, and use of data.
A database management system, like Access, allows you to use a computer
to:
A database is a collection of data which is organized in a manner that can be easily retrieved. They consist of fields, records, and files, much like a phone book. A field is a single piece of information (your last name is one field); a record is one complete set of fields (your entry in the phone book is a record); and a file is a collection of records (the entire phone book). When you look at the phone book for someone's phone number, you search for the phone book database.
Databases, like Access, are used to store large quantities of information. The information can be viewed, sorted, manipulated, retrieved, and printed in various ways. The database give you the flexibility to obtain this data in multiple formats.
A database management system consists of a collection of tables, forms, reports, and queries. In a sense then, the database is a hierarchical structure under which all the files (tables, forms, reports, etc.) fall under. Look at the illustration below for an example of the hierarchical structure.
