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 first database systems were based on the network and hierarchical models. A database can be defined as a collection of non-redundant data which can be shared by different application systems. A database implies separation of physical storage from use of the data by an application program to achieve program/data independence. Using a database system, the user or programmer or application specialist need not know the details of how the data are stored and such details are usually "transparent" to the user. .
Databases always used to fascinate me from my under graduation with great curiosity to know how large data is managed and queried. This led me to do Masters in computer science concentrating in the field of Data Management. In the course of my study, I understood the concepts of DBMS which provides a robust and efficient way of managing and mining data. Through the courses like Database Systems (ITCS 6160), Knowledge Discovery in Databases(ITCS 6162) and Knowledge Based Systems(ITCS 6155) I gained enough theoretical and practical knowledge about the importance of proper organization of data, good techniques to build an efficient database management system and how well the data can be managed.
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.
This paper will compare and contrast five different database management systems on six criteria. The database management systems (DBMS) that will be discussed are SQL Server 2000, Access, MySQL, DB2, and Oracle. The criteria that will be compared are the systems’ functionality, the requirements that must be met to run the DBMS, the expansion capabilities – if it is able to expand to handle more data over time, the types of companies that typically use each one, the normal usage of the DBMS, and the costs associated with implementing the DBMS.
For this coursework two kinds of data models can be used. The object oriented data model, Object Oriented Database Management System(OODBMS), or the relational data model, Relational Database Management System(RDBMS). The differences between these two models and the data model to be used are described in this chapter.

The success of a project can be severely be impacted if each of the key components is not planned out carefully and correctly. For more and more projects these days, a database is one of these key components. The database, while always given attention, is often not given the full planning that it deserves. This lack of planning at the beginning of a project could potentially lead to additional difficulties for the development team or result in limitation in both functionality and performance once the project is completed. To help with the planning of a database their exists a number of tools and methodologies, many of them follow the plans outlined by Dr. Peter Pin-Shan Chen and use the Entity-Relationship Model as their basis.
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.
According to Modern Database Management eight edition, by Jeffrey A. Hoffer, Mary B. Prescott and Fred R. McFadden database management system (DBMS) is define as a software system that is used to create, maintain, and provide controlled access to user databases.
Satzinger, Jackson & Burd (2010, pp. 488) further states that DBMS “provide designers, programmers and end users with sophisticated capabilities to store, retrieve and manage data”. Sharing and managing the vast amount of data needed by a modern organisation simply would not be possible without a database management system.
Secondly is a DBMS as a storage management that create a structured required from a complex data. This way will avoid us from having a difficult way to define and programmes the information data characteristics. DBMS consist of modern DBMS that provide another function in deep compared to the common DBMS. This modern DBMS will also include related data foe entry form, or screen definitions, report definitions, data validation rules, procedural code, structures to handle video and picture formats,
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.
Database management system (DBMS) is a collection of interrelated data and a set of programs to access the data. The collection of data, usually referred to as a database, contains the information related to the Company, the company's system at workplace, detailed information as an example employee personal information stored in the data. The goal of a database management system is to provide a way how to store and retrieve data information more efficiently. For examples, of the data, consider the name, telephone number and address are known, the recorded data is indexed address book, can be stored on a floppy disk, using a personal computer and software such as dBase IV or V, Microsoft Access or Excel
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.
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.
