What are the reasons to use a relational database?

13
A relational database allows you to easily find specific information. It also allows you to sort based on any field and generate reports that contain only certain fields from each record. Relational databases use tables to store information.


Hereof, why is relational database most popular?

The Relational database became popular because of SQL and its programming abstraction. It is difficult to displace relational databases by graph-based databases because of established user base and installations. Relational databases are just simpler to use, model and have established practices for their management.

Subsequently, question is, how does a relational database work? A relational database stores data in tables. Tables are organized into columns, and each column stores one type of data (integer, real number, character strings, date, …). The data for a single “instance” of a table is stored as a row. To improve access time to a data table you define an index on the table.

Similarly, it is asked, how do you use a relational database?

Relational Database Design Process

  1. Step 1: Define the Purpose of the Database (Requirement Analysis)
  2. Step 2: Gather Data, Organize in tables and Specify the Primary Keys.
  3. Step 3: Create Relationships among Tables.
  4. Step 4: Refine & Normalize the Design.

When should I use NoSQL?

You might choose a NoSQL database for the following reasons:
  1. To store large volumes of data that might have little to no structure. NoSQL databases do not limit the types of data that you can store together.
  2. To make the most of cloud computing and storage.
  3. To speed development.
  4. To boost horizontal scalability.

Normalization is a systematic approach of decomposing tables to eliminate data redundancy(repetition) and undesirable characteristics like Insertion, Update and Deletion Anomalies. It is a multi-step process that puts data into tabular form, removing duplicated data from the relation tables.
