Database Management Systems Or Dbms

A Database Management System or (DBMS) is an essential tool for any organization or company in today’s modern world. A DBMS is “a group of programs that manipulate the database and provide an interface between the database and its users and other application programs” (Stair & Reynolds, 2011, p. 189). So in choosing the right DBMS there are many factoring issues with choosing the right one for the company or organization. When choosing a DBMS one has to think about how the system will ultimately help the company or organization with day to day processes and the goals of the company or organization.

Vaughn (2012), states several reasons for increasing amounts of data being handled by databases. The first is simply due to an increase in technology available and the number of people using this technology. As the amount of data increased, organizations began to want to mine the data to find information that they can use to increase their business. Mining the data that was stored in the systems quickly became a determining factor in strategy and future tactics of the organization. Data continued to increase and organization soon found themselves having difficulty processing this data in a manner that was timely enough to be useful.

Connolly and Carolyn (2004) define a database as a structureordesign that consists of theclient’s data as well as metadata. It is also a persistent, logicallycoherentrepository of inherentlymeaningful data that is relevant to someaspects of therealworld. The database consists of data organized in a systematicway, anditallowseasy retrieval of information, analysis, updating andoutput of data. Thatdata can be in theform of graphics, scripts, reports, text, tables, andsoon. Most of thecomputerapplications are databases at their core. Manycompaniesusuallyhave a lot of data, andsotheyhavebig databases that can handlethatlargeamount of data. It is wherenothe database administratorcomes into playtopensurepropermanagement of the database sothatthe organizational data is safe from anyintrudersor data corruption (Jones, 2014). The database is whatcontrolsthedata of theentireorganization, andany tampering of the databases can culminate to the stoppage of businessoperations.

A DBMS is a software program that is intended to manage and query multiple databases. A single database is comprised of tables of relational data, whereas a DBMS can manage relational data that crosses more than one database, and it serves as a manager of the interfaces between the numerous databases, allowing relationships to between databases to be formed. Database managers enhance the classic search feature in most systems to be that much more powerful and vigorous (Onh, 2009).

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.

As computers grew in speed and capability the same had to be with information storage. In the 1960s, the term database management was coined in to existence. That’s when two standards emerged, the hierarchical model was by IBM’s Information Management System and the other was the Network model by Charles Bachman IDS (Integrated Data Store). With the introduction of these two models indicated how serious business data was becoming to the world.

Databases are used widely in our life. Because of databases, vast amounts of data have become easier to use and manage. Government, finance, operators, public security, energy, taxation, business, social security, transportation, health, education,

Databases have been in use since the early days of computing programs. An Information Technology services company, such as Getronics, not only utilizes databases for information and record management, it earns revenue by providing database management services. Getronics uses Microsoft SQL Server 2000 as its database software. The clients that contract Getronics for Information Technology services rely and depend on the accuracy and currency of the database information that is stored. Databases will continue to exist and expand as more companies become more of aware of the importance of record and data management.

In non-database systems (traditional computer file processing), each application program has its own files. In this case, the duplicated copies of the same data are created at many places. In DBMS, all the data of an organization is integrated into a single database. The data is recorded at only one place in the database and it is not duplicated. For example, the dean's faculty file and the faculty payroll file contain several items that are identical. When they are converted into database, the data is

Relational Database Management System (RDBMS) is an engine/system based on the relational model created by Edgar F. Codd in 1970. The major distinguish of this system is the ability to use tables for data storage while maintain and enforce certain data relationship. Another aspect of this system is that allow users to insert, update, retrieve, and delete specific content or contents storage in the database. Also, RDBMS provides relational operator codes that enable the relationship between two or more entities in a database (Dangerfield & Morris,1990). These system’s characteristics can be applied on business operations improving company management of small and large amount of information from a specific department or workplace. Relational Database Management allows monitoring all information flow from that specific department

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.

Database Management System plays a vital role in most of the real world applications that require storing and retrieving data. Database Management Systems are the most reliable means to organize data. DBMS organizes data into collections from which data can be searched or updated to. There are many different forms and types of DBMS products available in the market each having their own pros and cons. The main DBMS products that are available in today’s market are Oracle 11g, Microsoft SQL Server 2012, IBM DB2 and MySQL 5.5.

In the world of computer science large groups of data that are collected are referred to as databases. When there is a multitude of these databases, a way to manage all of this information is needed. That is where database management systems (DBMS) come into play. “A database management system is a collection of programs that enables users to create and maintain a database. The DBMS is a general-purpose software system that facilitates the processes of defining, constructing, manipulating, and sharing databases among various users and applications” [1]. Analyzing these database managements systems could potentially have huge benefits since companies could determine when and where to sell products, track certain trends, and possibly predict future outcomes.

Object databases don’t store data they store objects instead. An object is given an identity so it can be referenced. Objects consist of attributes and methods. Attributes are characteristics that define the

Data is at the centre of most today’s businesses and businesses must pay close attention to how they access, store and use data. One of the systems at the heart of current data management is different database management system.
