Database Management System: Data Model

Abstract

In this paper, we are talking about the modern application require database to catch and execute more in closure semantics than traditional application. In order to collect and analyse data, a database management system communicates with applications, end users, and the database itself. A database is a structured collection of data that is electronically accessible and stored. Large databases are housed on clusters of computers or cloud storage, whilst smaller ones can be maintained on a file system.           Data modelling, effective data representations and storage spaces. Languages, security and privacy of private information, and distributed computing concerns that permit concurrent access are all part of the design of databases. The primary tools offered to manage the database are also included in the DBMS software. A database system is the collective name for the database, the database management system, and any related applications. In this paper, we revisit the data models, in which such models play a role in the process. Analysis of the data objects and how they relate to other things is done through the process of data modelling. It is employed for the analysis of the data requirements needed for business processes. On the other hand we also talk on other essential part of data model and its types like relational, hierarchical, network and entity relational (ER) model.
