Although the database system yields considerable advantages over previous data management approaches, database systems do carry certain disadvantages. Such as:
1. Increased costs:
Database Systems are in requirement of hardware as well as software of a sophisticated nature, along side personnel who are deemed highly skilled. the cost of maintenance of the personnel, the hardware & the software, required for the operation and management of a Database Management System may be considerable. regulation licensing, & compliance & training costs are many at times looked over on the implementation of the Database System.
a.) Cost of Hardware & Software:
A processor capable of processing data at high speed, as well as, a sizeable memory are the prerequisites which are required in order to execute the DBMS software. this implies that one has to upgrade the hardware used currently at use for file-based system. in a similar fashion, DBMS

this is a cumbersome as well as time intensive way to transform data of data files into database. one has to hire/employ a DBA & System Designer, along side some application programmers; As an alternative, one must avail the services provided by certain software houses. therefore a substantial expenditure must be incurred in order to Develop a database & other such software of relevance.
c) Cost of Staff Training: the majority of the DBMSs are considered Complex-systems, therefore, Users require specialised training in order to use the Database. this training is multi-levels, & encompasses training in the fields of programming/coding, the development of applications, as well as, the administration of databases. therefore the organisation has to incur heavy expenditure in order to train the personnel to use the Database Systems
2. Management
Database tools and technologies affected the business processes and decision making by a great extent. The most important benefit of the database is to change unstructured information into structured information, and allow users to analysis the data stored into different tables with the help of queries. Before database, all the information used to stored into paper and other unstructured computer programs, due to which getting required information process was very slow. Due to database, all the
A database administration framework (DBMS) is a PC programming application that connects with the client, different applications, and the database itself to catch and dissect information. A universally useful DBMS is intended to permit the definition, creation, questioning, upgrade, and organization of databases.
Describe the types of facility you would expect to be provided in a multi-user DBMS.
* Describe the role of databases and database management systems in managing organizational data and information.
Database plays a major role in any organization. As a Database administrator(DBA) he/she is responsible in developing, implementing and maintaining the databases and DBA 's are also responsible in updating, backup 's and security of the databases. The first Database Management System was developed in the late 1960 's by two firms based on their network data model but in the early 1970’s a scientist of IBM introduced Relational database theory after six years IBM completed prototype on RDBMS (relational database management system). Oracle created the first versatile Relational Database Management Systems In 1983, which allowed organizations to use their DBMS on different machines including mainframes, workstations, and Pc 's. In 1993 Microsoft first created a database application called Access for Macintosh machines. Microsoft SQL server is a RDBMS which is used to store and retrieve the data by other software applications. There are 12 types of servers concentrated on various types of user 's from single computer to large networks (Microsoft SQL DBA).
There are several important steps to consider when designing a database, as a well-designed database should be deployed and not only support the accuracy and integrity of business information but also avoid redundant data and assist with has enterprise level reporting tasked. If we analyze the
Database systems provide efficient access to large volumes of data and are vital to the operation of many organizations.
As you recall, data is a collection of facts (numbers, text, even audio and video files) that is processed into usable information. Much like a spreadsheet, a database is a collection of such facts that you can then slice and dice in various ways to extract information or make decisions. However, the advantage and primary use of a database over a spreadsheet is its ability to handle a large volume of data and yet allow for quick access to the information that is desired.
Database Processing: is the system of collecting, storing, and processing data for the purpose of gathering information, managing information, and creating new knowledge from the stored data. Database Management Systems: Data processing in business is most often done using Database Management Systems (DBMS). A DBMS is used to create, process, and maintain a database. Some common inputs and outputs of a DBMS include; tables and forms to input data, queries to retrieve data, and reports to output and present data. Enterprise Database Managements Systems: this is a database system that supports a multi-user environment. These are most often used in large businesses that require employees to input and process data using a variety of different applications. Common enterprise technologies
Database system design can be extremely time-consuming as it takes sophisticated software to create and control it. The design process becomes less user-friendly as it takes a more extensive knowledge of how to use it. The standard of an excellent database is one, which is complete, integral, simple, understandable, flexible and
Write and describe a variety uses organisations make of use of databases and the issues they face - P1.1
Migrating from the manual and paper file set up is always an advantage in its own capacity. We shall highlight the major advantages of using a database or Data Base Management System in an organisation. Using a database will reduce both data redundancy and inconsistency. For larger or even smaller organisations like a small time starting estate agency, a database will promote sharing of data for example when referring to client files.
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.
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.
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.
