Example 1 – Consider the following relational database for the Super Baseball League. It keeps track of teams in the league, coaches and players on the teams, work experience of the coaches, bats belonging to each team, and which players have played on which teams. Note the following facts about this environment:

In order to obtain peer reviewed research articles related to the impact of the psychological contract on job satisfaction in community mental health care workers it is important to review research that has been completed in a variety of researchers and in different settings. The databases that were selected to locate peer reviewed articles for this paper where Academic Search Complete and ProQuest Psychology. Tutorials were available for each of these databases and ProQuest was used to learn how to navigate through the data base since it was not a familiar data base to this author.

Databases allow us to easily store and retrieve data in a purely digital format. The strength of this is that large amounts of data can be stored and retrieved with minimal effort on the part of the user. Opposed to manually flipping through files, one can quickly pull up the requested data through a computer program. Many systems that were conventionally paper and file based have been converted to a digital format which are now stored in one or more databases.

“A database is a structured collection of records or data that is stored in a computer system. In order for a database to be truly functional, it must not only store large amounts of record, but also be able to access those records fast and efficiently. In addition, new information and changes should also be easy to input.” (tech-faq.com) To be useful over a long term the database should be able to store all the records necessary for the business to function as well as be able to get all of this information back in case of a system failure or a crash. If all the information is loss a business could go bankrupt so the database is a fail

Data has always been analyzed within companies and used to help benefit the future of businesses. However, the evolution of how the data stored, combined, analyzed and used to predict the pattern and tendencies of consumers has evolved as technology has seen numerous advancements throughout the past century. In the 1900s databases began as “computer hard disks” and in 1965, after many other discoveries including voice recognition, “the US Government plans the world’s first data center to store 742 million tax returns and 175 million sets of fingerprints on magnetic tape.” The evolution of data and how it evolved into forming large databases continues in 1991 when the internet began to pop up and “digital storage became more cost effective than paper. And with the constant increase of the data supplied digitally, Hadoop was created in 2005 and from that point forward there was “14.7 Exabytes of new information are produced this year" and this number is rapidly increasing with a lot of mobile devices the people in our society have today (Marr). The evolution of the internet and then the expansion of the number of mobile devices society has access to today led data to evolve and companies now need large central Database management systems in order to run an efficient and a successful business.

The general theme behind a database is to handle information as an integrated whole. A database is a collection of interrelated data stored with minimum redundancy to serve many users quickly and effectively. After designing input and output,
