Choosing a database is an important task that every company must carefully consider. Two types of databases that a company may consider are open source and proprietary. Both open source and proprietary databases have numerous advantages and disadvantages. In this paper we will discuss some of these advantages and disadvantages. We will also discuss some things that a company should consider when they are choosing a database. There are many different types of open source databases. Some of these include MySQL and PostgreSQL. In addition to being cost free MySQL is very reliable and easy to use and fast. This makes it a great choice for many companies. PostgreSQL is very powerful as well as reliable. In addition it can be used with all of the major operating systems. PostgreSQL is a great choice for companies because it can handle vast amounts of information. Proprietary databases are something that most people are aware of. Some examples of proprietary databases include Lexis-Nexis, STN and DIALOG. Lexis-Nexis offers a variety of products and is used mainly with corporate, legal and government accounts. STN offers a large amount resource for its customers. DIALOG is one of the earlier databases that still have a lot to offer. Like STN it offers multiple products and multiple resources. Before a company can choose any particular database it may be best to first choose whether you should use an open source database or a proprietary one. There are some obvious benefits to open source databases. First of all open source databases are cost effective and often offer features that are comparable to or even better than those of proprietary

Database systems are designed to allow developers to create a database, fill it with information and be able to call up that information and change it as necessary. This also allows the user not to worry about data storage and retrieval. Some of the other aspects to database systems are:
“User access and security management systems provide appropriate data access to multiple users while protecting…
Normalization is an important part of database design. Research and comment on Normalization and any experience that you may have had with this technique.
The concept of improving a database through normalization revolves around the ideas of efficiency and relationship building. Normalization improves design and is widely used. Two goals exist in this pursuit; they are “eliminating redundant data…and ensuring dependencies make sense (only storing related data in a table)” (Chapple, 2013). Redundancies…

Databases are a key elements of today’s business world. Almost every company in the world makes use of databases to help store, process, and utilize information to achieve various tasks and goals. To get the most out of databases companies employ database management systems. In this paper we will be taking a look at what database systems are, as well as the architecture that defines them.
Before we begin it is important…
“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…
Database Design Life Cycle
The end state of this database is that the supervisor and forensic examiners of the digital forensics unit will be able to access both historical and current data on the forensics examinations processed thought the forensics lab. Statistical data will be available as it relates to the types of crimes that require digital forensic examinations, if there are cases that involve repeat offenders and the success rate of closed cases.

Database Systems and Their Architectural Design
According to PCMag Digital Group (1996-2015) a database system is defined as "software that controls the organization, storage, retrieval, security, and integrity of data in a database" (para. 1). Database systems consist of the following four components- end users, database application(s),the database management system, and the database…
