A database is a computer program used to store and organize information like text, numbers, dates, images, and sounds in an easily accessible way. When setting up a database, it is important to plan in advance what information will be stored, how it will be accessed, who will use it, and whether access should be restricted for some users or data. Microsoft Access is a relational database management system supported by IT Services that allows linking of data across multiple tables. To open an existing Access database, click Open, navigate to the folder containing the file, select the file, and click Open.
