Relational Database Design


Edgar Codd proposed the Relational Database in the year 1969. Since then, it has become the leading database model as compared to other models like the network & object model, hierarchical etc. Today, there are several commercial database models like Oracle, IBM DB2 etc.

A relational database is used to organise data in the form of tables which has rows and columns. A row is also known as Tuple or record whereas columns are represented as field or attribute. A database table is just like a spreadsheet. We know that SQL is a language and it was developed to work with a relational database.

Relation Database Design Process


Database design is not just science but an art. It includes creative decision making for business problems. Guidelines for the same are mentioned below –

Step 1


Firstly, you need to describe the aim of the Database by collecting the information.

Step 2


Now, after defining the aim of a database, collect the data that needs to be stored and organised in the form of tables.

Step 3


After this, create a relationship that can be defined in the form of tables.

Types of table relationships:



  • one-to-many

  • one-to-one

  • many-to-many


Step 4


Improve and Normalisation the Design

What are the Benefits of Good Database Design?


Making a good database design can be a time-consuming process, still, students fail to provide a well-structured database. A well-structured database design is the best for long run because you do not need to refurbish an instantly generated poor designed structure. You will get following benefits from a well-designed database:

  • The database structure can be modified easily. For example – If we modify a table it will not affect other tables of the database.

  • Data is also easy to alter. Only such fields are affected, wherein the changes have been made.

  • Information can be regained easily when database design is well- formatted and tables are correctly established.

  • End-User applications are easy to develop and build. You can spend more time on programming and addressing the data manipulation tasks at hand, instead of working around the inevitable problems that will arise when you work with a poorly designed database.
