Entity Relationship Modelling

The database is the backbone of any organization. Flow of data and data management create DBMS in an organization. Professionals in this field need to develop DataBase Management System (DBMS) for an organization as a whole for the best possible data management and flow of data. In this system, the first job is to draw a complete diagram that would show the complete data base model encompassing all the major and minor entities belonging to the organization. This is called ERM. It is obvious, without a thorough and perfect ERM, the next steps in the DBMS cannot be rendered successfully.

So, ERM is the graphical illustration of entities and their relationships in an organization. It is typically used in computing for the best possible organization of data within the databases or information systems, or in a single database. Here, relationships are represented as lines joining the points or entities, which are represented in different geometric forms, like polygons, circles, or ovals. An ERM should have an equivalent relational table, and vice versa. ERM is a vital support for the concerned experts in the design, optimization, and fixing bugs or problems of database programs.

A relationship between two entities is nothing but how data is shared between two entities in the system.

Normally, three types of relationships are in concern:

One-to-one – Each employee in an organization may have only one employee code in the organization. It is one to one relationship.
One-to-many – Ten employees are working in the marketing department is an example of one to many relationships.
Many-to-many – When all the employees are working in more than one project at a time, it becomes an example of many-to-many example.

So, ERM follows specific system, and students need to understand that system and related rules and regulations thoroughly in order to write the assignments correctly.

In an ERM, different symbols are usually used to represent the types of information. Most diagrams use the following figures:

Boxes signify entities.
Diamonds signify relationships
Circles, or ovals signify attributes.

Attributes in an ERM

Entities in an ERM are represented with the help of their key features, called attributes. These attributes have specific values that help the people to recognize the entity clearly, like the attributes of a student are his or her name, class, roll number, and age.
