Database Management Essay

data access tools, recovery, audit, distributed data management, backup, transaction processing] Answer: - SQL is known as structured query language to manipulating and accessing database. And it is designed to manage large amount of data of company. It’s manage and make us easy to find any information in less time. SQL was developed by IBM in 1970’s by Donald D. Chamberlin and Raymond F. Boyce. MySQL is an open source relational database management system it is developed under the General Public License

NOSQL is an emerging class of non-relational database, used to handle Big Data, it stands for Not Only SQL which solve the problem of processing unstructured data, considering that this non-relational database does not use a schema, and does not relay on the table/key model used in RDBMSs (Relational DataBase Management System). NOSQL have the following characteristic: • Scalability: the competence to store data across multiple data stores simultaneously, moreover enlarge and decrease the size of

Relational and Object-oriented Database Management Systems A database is a “shared collection of logically related data designed to meet the information needs of multiple users in an organization” (Hoffer 709). Databases contain data records or files, such as sales transactions, product catalogs and inventories, and customer profiles. Databases allows multiple users in an organization to easily access, manage, store, and update data when needed. A database management system is software designed

Differentiate between database management system and information retrieval system by focusing on their functionalities. Answer A database management system (DBMS) is the main software tools of the database management approach because it controls the creation, maintenance and use of the databases of an organization and its end users. Information retrieval is a system that to provide the relevant information based on the user needed. This process can be find through the passwords or keywords or query

DBMS Database Management System or DBMS is a collecting computer program used for creating, deleting, editing and maintaining collections of different data records. There are many different types of database management systems; they are used to stored, managed database model. Different DBMS systems are Relational Database System, Flat Files Base Database Management, Hierarchical Database Management Systems, Network Database Management System and Object-oriented Database Management Systems.

Discuss the tradeoffs between relational and object-oriented database management systems 1) Stating Position The object oriented DBMS is superior to the relational database on some specific counts, primarily because it can satisfy the complex demands of the market today better than the any other. Secondly while the relational data base stores data as tables, the object model stores data as objects and creates associations. This can create a multiple set of attributes for each object such that

A database system is a rich pool of data from which information is extracted and used for day to day operations and long term planning. Database management systems come along with applications that help individual processes. The three main sources of these databases are operations, purchases, and extracts of operations (Kroenke & Auer, 2012). Information Systems are a set of interrelated components that collect, retrieve, process, store and distribute information to support the decisions made by

ADVANTAGES AND DISADVANTAGES OF DATABASE MANAGEMENT SYSTEM When we learning about Database Management System we have to learn their advantages and disadvantages too. After many researches and developments DBMS become very flexible to use. So there are many advantages using DBMS. Let us see what are the advantages that using a DBMS.  Data Independence : It’s not exposed data of Data representation and storage ideally in application program.  Efficient Data access : Using variety technical functions

hardware components, system software and to applications. In this paper, I have described the concept of energy efficiency problem and recent techniques to design energy efficient database management systems. I have broadly classified recent research into three categories: hardware based, software based and cluster based database designs. Last section of paper includes a description of power models used for evaluation of energy efficiency solutions. Section 1 Introduction Data center industry supporting

for an efficient data management and retrieval of data has always been an issue due to the growing need in business and academia. To resolve these issues a number of databases models have been created. Relational databases allow data storage, retrieval and manipulation using a standard Structured Query Language (SQL). Until now, relational databases were an optimal enterprise storage choice. However, with an increase in growth of stored and analyzed data, relational databases have displayed a variety
