    A database is a set of programs and applications used to store data, this allows the data to be used by different individuals in different areas and access information from it quickly. A database stores the information so it can be used at a later time so additional information can be added, taken away, or used as needed. Once in the database the data is compressed so it takes up less space in the computer’s memory. The database allows those authorized to use the data within it and control the creation, maintenance, and use of a database. A database stores various kinds of files, data records, and other objects. There are a variety of database models; there is the relational model or object model, which supports applications. That use query languages, which are high-level programming languages, and dedicated database languages that simplify writing database application programs. The main function of a database is basically retrieving and presenting information it controls, in doing this it allows the users data access, protects the data’s and makes it more manageable. It also provides safety features for the data so that it is not lost or misplaced and if there is a serious event or natural disaster, fire, etc. it can be recovered and restored from a backup. In my work we use Microsoft Access as a relational database for employment records and to store our client information such as names, addresses, phone numbers, and email addresses from this database we send out a monthly newsletter with special offers on services and products. By using a database, an organization saves time and money because it is only a few simple steps and we can email all of our clients and customers a monthly newsletter which informs them about what is happening within the organization, services and products we offer, and what is on sale which generates more business.

A database is an integrated collection of logically related data elements that are organized into a common pool of data elements (O 'Brien & Marakas, 2011). These elements are stored in such a way that they are not dependent on any one program or any piece of hardware. Thus allows data to be shared easily between programs.…

    National Restaurant Chain Database

    Using a database management system (DBMS) is a wise decision for any business that plans to implement the use of a database as part of their IT infrastructure. A database management system, also referred to as a database manager (Rouse, 2005), allows one or many computers to create, query, and manipulate data in the database (Rouse, 2005). The database management system also manages request from users and applications, making the database much more user friendly, since the users nor the applications have to know where the data is physically located for the database (Rouse, 2005). Where multi-user systems are being utilized the database management system does not allow the current user to see who else is accessing the information. The database contains data that needs to be protected from intentional or accidental misuse (Ricardo, 2012). The database management system is instrumental to securing the database; and that system allows the database administrator to setup security restrictions and enforce them on multiple levels, making sure only those with the proper credential have access to the data (Ricardo, 2012). The DBMS also adds to the overall security by having the functionality to encrypt the data before it is stored in the database (Ricardo, 2012). The database management system also helps to ensure database integrity, making sure data is readily accessible and is organized as intended by the database administrator (Rouse, 2005). The DBMS also allows the database administrator to define integrity constraints, which are consistency rules that the database must obey (Ricardo, 2012).…
