Building up an entity-relationship (ER) model is to graphically represent an enterprises’ business structure, in which data matches with objects that are connected by specific relationships depicting needs and requirements. Innately, it is a conceptual infographic, the initial phase in the design process in the direction of constructing a logical and functional database.

The idea was originally stylized by Peter Chen, the leading computer scientist who composed The Entity-Relationship Model - Towards a Unified View of Data. In the paper was given, organized documentation about database models. It is still most preferred standard right up 'til the present time, however different documentations, like, Bachman, Barker, or Martin, were devised to manage explicit database needs.

The Process

The relational data analysis tools help an IT expert or designer in creating successional relationships by ordering comparative characteristics, found within the data-set, by way of three building blocks: entity, relationship, and attributes. Entity is likened with nouns such as an individual (worker, client, or consumer) a place, or things (products sold, purchased or rejected). A relationship is outlined among the entities. Relationships can likewise be just considered a Verb used to connect at least two nouns. Entity along with relationship will then be related to their attributes. Like: a pack of black chocolates with a date of expiry or ED attribute. The attribute will elucidate an entity’s specific determining feature and will serve as its Primary Key.
