The ultimate aim of this paper is to discuss the history of Database Management Systems (DBMSs) and in particular the Relational Database Management System (RDBMS) (McManus, 2003). The paper will start with the definition of DBMSs and an explanation of their functions. The paper will then list the various database models in existence today. The next stage will be to dive in to the history of DBMSs starting from the 1960s, when the first database systems made their way into the computing world to modern trends in DBMS development. This history will be explained in three main stages. First, the 1960s navigational databases, which took two main approaches – the Codasyl approach and IBM’s IMS will be discussed and the concepts behind them illuminated. Secondly, the paper will explore the relational model that gained prominence in the 1970s especially after the publication of Edgar Codd’s ground shattering paper on the relational approach. Some significant amount of effort will be spent on the concepts proposed by Edgar Codd and how they were radically different from those employed by navigational databases. Thirdly, the late 1970s and early 1980s Structured Query Language (SQL)-based DBMSs will be discussed at length with the DBMS historical chronology ending with a mention of the most popular RDBMs such as Microsoft SQL Server, Oracle, Sybase, PostgreSQL and MySQL. Finally, the impact of database systems on businesses will be explained in detail.
History of Database Management Systems (DBMSs)
Perhaps, before diving into concepts related to the history of DBMS, it would be prudent to present a thorough definition of DBMSs and their functions. A DBMS refers to a collection of software programs that aid in the construct...

The growth of online business has grown enormously over the years. Cliptomania is a family operated and owned small e-business that primarily sells clip on earrings (Brown, DeHayes, Hoffer, Martin, & Perkins, 2012, p. 308). Cliptomania early developments were very modest, and as such the company experienced copious strategic dilemmas. An initial strategic dilemma that the company encountered when establishing and building their new e-business undertaking was to create a website for the business operations and essentially to have it fully operable. The owners, Jim and Candy elected to hire a vendor to host the website and additionally utilize the IT systems resources of the vendor to sustain their business. At the very beginning they exploited the offerings of the Yahoo Store. However, continuing down this avenue of using the services of the Yahoo Store inevitably became too costly. By using the services and business offerings of a vendor made it convenient and effortless for Jim and Candy to start their e-business store. Unfortunately the couple did not have much in the way of professional help, and so they had to create and put together the website by themselves. Additionally they also had to deal with establishing their online credibility as many customers preferred to call in their orders just to talk with a real person before being comfortable enough to place their orders via the webpage.
On the other hand it has made it much more competitive for viewers attention. Creating a unique brand, utilizing all the tools available and being consistent can offer a good return.
Databases and Y2K Introduction: Tremendous problems loom just around the corner for organizations that use two-digit years (i.e. 1-9-97). How tough could it be to change the year from 1999 to 2000? The "Year 2000 Problem" cannot be fixed by simply resetting a computer's internal clock on January 1, 2000. Computers may be smart, but their programmers weren't very farsighted.
In 1977, Larry Ellison, Bob Miner, and Ed Oates founded System Development Laboratories. After being inspired by a research paper written in 1970 by an IBM researcher titled “A Relational Model of Data for Large Shared Data Banks” they decided to build a new type of database called a relational database system. The original project on the relational database system was for the government (Central Intelligence Agency) and was dubbed ‘Oracle.’ They thought this would be appropriate because the meaning of Oracle is source of wisdom.
Database management system is a group of programs, which enables a user to modify, extract, and store information/data from a database. The system is designed in such a manner that user can be able to access the information they need. The company will uses a soft ware known as database management system, which will be responsible for controlling the data storage, data organization, and data retrieval. In addition, a DBMS will help in reducing data redundancy and inconsistence of the data, and provide the necessary security required to protect the data from being accessed by unauthorized person (Harrington, 2002). Additionally DBMS has a recovery mechanism thus data deleted by mistakes or lost will easily be recovered.

Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
The reason for the selection of this topic is because it falls under the computer science category. We have been studying databases for four years and so the this topic area will be of great use when venturing into the cooperate world.
A database management system, or DBMS, gives the user access to their data and helps them transform the data into information. Such database management systems include dBase, Paradox, IMS, and Oracle. These systems allow users to create, update, and extract information from their databases. Compared to a manual filing system, the biggest advantages to a computerized database system are speed, accuracy, and accessibility.
Data Normalization Data normalization is an important step in any database development process. Through this tedious process, a developer can eliminate duplication and develop standards by which all data can be measured. This paper addresses the history and function of data normalization as it applies to the course at hand. In 1970, Dr. E.F. Codd's seminal paper "A Relational Model for Large Shared Databanks" was published in Communications of the ACM. This paper introduced the topic of data normalization, so-called because, at the time, President Nixon was normalizing relations with China.
The Database Management System (DBMS) is software that enables the users to define, create, maintain and control the access to the database. It is a software that interact with the user’s applications programs and it database. Meanwhile, information retrieval system is a system that involved the activity that the systems obtain the information. The obtaining information action need the information from it resources.
of multiple types of end users. The data is stored in one location so that they
Having a website is a necessity nowadays, especially for people who are in business.

In our world, people rely heavily on the power of technology every day. Kids are learning how to operate an iPad before they can even say their first word. School assignments have become virtual, making it possible to do anywhere in the world. We can receive information from across the world in less than a second with the touch of a button. Technology is a big part of our lives, and without it life just becomes a lot harder. Just like our phones have such an importance to us in our daily lives, database management systems are the same for businesses. Without this important software, it would be almost impossible for companies to complete simple daily tasks with such ease.
Businesses can build their own websites and buy their own memorable .com domains. This can be where they explain their company and the services they offer. Some can even offer home delivery directly from the Internet with things such as home shopping. This makes life very easy for disabled people or people with busy lives who have no time to go shopping.
