Relational Database Management System: A relational database management system is a database management system that stores the data as tables which can related to each other. The tables might be related to each other by common attributes. It consists of a set of tables or files containing data that is fitted into some particular groups. These tables have data in the forms of rows and columns. Relational databases allows the user to update delete add and access a data entry from the tables.
Store data is usually organized into fields, records, files and databases. 3. Retrieval of information. MIS retrieves information from its stores as and when required by various users. According to the requirement of the management of users, the retrieved information is spread or rework to meet the specific requirements.
Abstract Purpose of study The purpose of this study was to evaluate the impact of Database Management Information and its technologies in increasing employee productivity at RasGas Subsurface and Technology Company. Looking the the recent advancement of technology, companies have gone a mile further to develop database management systems that seek to address all components of a business from one particular place. Employees, suppliers and other stakeholders can now be addressed within one basic system. With increased competition, the Qatari company has clearly had a competitive advantage with such technologies. Design/methodology/approach used in the study To present the research, an overview of the use of the database management system was
Big Data is also geospatial data, 3D data, audio and video, and unstructured text, including log files and social media. Traditional database systems were designed to address smaller volumes of structured data, fewer updates or a predictable, consistent data structure. Traditional database systems are also designed to operate on a single server, making increased capacity expensive and finite. As applications have evolved to serve large volumes of users, and as application development practices have become agile, the traditional use of the relational database has become a liability for many companies rather than an enabling factor in their business. Big Data databases, such as Mongo DB, solve these problems and provide companies with the means to create tremendous business value.
Now a days every organization has automated their systems of information by handling the database with personal or any type of secret information. So, with these type of crucial and sensitive data, security and privacy issues becomes necessary. Now the question arises that what is database security and how it can be achieved? Protecting the private and personal data saved in any archive is known as database security. It deals with securing the database from intruders and illegal actions.
Relational Database Management System: This type of database management system that stores the data in the form of related tables. It is a social database administrator which deals with some typical kind of queries and uses SQL for the development of the database. This type of database is a very powerful database as it deals with the relations which makes the data manipulations easier other than any other database. It has the features of data entry, data deletion, and creating of new entry and records etc. the database provides the ease of accessing and maintaining data easily.
- The database also contains data fields which labels each file within the database allowing you to understand which data is contained in which file. - It also consists of records which allow you to retrieve data about a particular individual in the database. Advantages: - You don’t need to change multiple records as the files in the database are relationally linked to each other. This also makes it simple to edit and update as the data within each record will automatically be changed as you change one record. - Reduces the risk of human error or duplication meaning that you don’t have to worry of about the risk records not being showed up.

If you have a large system, the operating system has greater responsibilities and powers. It makes sure that different programs and users running at the same time does not interfere with each other. The operating system also has a responsibility for security and ensures that any unauthorised users does
