  2. WHAT IS A DATABASE? A database is an organized collection of related information.

  3. Familiar Printed Databases • Telephone Directories • Address Books • Encyclopedias & Dictionaries

  4. Familiar Computerized Databases • SIMS (Student Information Management System) • Automated Card Catalog • CD-Rom Encyclopedias

  5. Advantages of Computerized Databases • Can find a specific file quickly • Can alphabetize and sort data faster than people • Is as accurate as the data that is entered • Can make many different types of reports

  6. WHO USES COMPUTERIZED DATABASES? • Stores use them to keep track of inventory • Travel Agents can keep up with their customers and reservations • Hospitals track • patient information

  15. Manipulating a Database • Retrieve a database file • Sort the database file • Use questions that involve ascending and descending order • Filter/Query/Search the database file • Use questions that involve one, two, and three criterion • Use questions that change the connector term from and to or

  16. Manipulating continued • Create a Report • Name Report • Choose Layout and Format • Choose Fields to Include • Determine a Sort Order • Create a Filter
