Entity Relationship Diagrams are the best tools to communicate with the entire system. These diagrams are the graphical representation of the flow of data and information. These diagrams are most commonly used in business organisations to make data travel easy.
The most common use of this diagram is to present the relation of the various tables present in a database. Some key benefits of Entity Relationship Diagrams are further discussed in this article.
The most crucial benefit of ERD is that it offers a visual presentation of the layout. Having an efficient design provides assistance to the database designers to determine the flow of data and working of the complete system. ERD in combination with data-flow diagrams results in an adequate visual representation.
The clear representation of the data listed under proper headings and tables results in the effective flow of information and communication. The readers can easily understand the relationship between different fields. The information is represented via different symbols.
There are various symbols for representing different information like relationships are represented by diamond-shaped boxes, ovals and entities represent attributes are represented by rectangular boxes. These symbols allow the designer to have a proper understanding of the working of the database after completion.
Easy to Understand
Expert designers can easily create entity relationship diagrams. These are designed solely so that all the individuals can understand it easily. Before actually designing the database, the designers are required to get the design confirmed and approved the representatives who are to use this data.
The representatives have the right to give their suggestions for rectifying the issues related to the designer. Their contribution can play an important role in enhancing the overall design.
This is yet another feature of ERD models. Though the complete database is linked to information in different tables, the readers can quickly make out the relationship between various tables. There are several other mathematical formulae which can be used to determine the relationships.
