What Is a Relational Data Base?

Data cleaning services in San Bernardino CA

Although relational databases sound intimidating, at its most basic, a database is simply a place to store information. Databases play an important role in data analytics, software engineering, data engineering, and other areas. This can look different in practice, but relational databases are a special type of database used to store and retrieve data from apps.

Because they are flexible enough to cover many industry uses, relational databases are very popular. You might be familiar with industry favorites such as SQL Server, MySQL and PostgreSQL even if you haven’t had the opportunity to use one.

What is a relational data base? You are probably familiar with Excel spreadsheets. They work in similar ways. A database can be thought of as having the same column and row structure. However, they are based on the idea of a table but have certain features that allow for data retrieval and analysis.

Multiple tables are common in databases. They can be linked together if there are overlapping columns or, in industry jargon: a primary key. Companies can use this interlinking architecture to help them make sense of the different types of data generated by their business lines.

The Relational Database Model

Let’s first look at the reasons that the relational database was created. E. F. Codd, an IBM employee, created the relational database in the 1970s. He wrote a paper outlining the rules for data storage. Each row has a unique primary key. Tables are related to each other if they have columns that correspond to the unique key. The foreign key occurs when the primary key is used in a different table.

Relational databases define the data types in each column, as well as primary keys and column names. These attributes are called the relational schema and they structure how new entries are added into a database.

This may seem too abstract. If you’re interested in analytics, it might be hard to conceptually understand why. Let’s look at an example of how businesses use them.

Let’s say you have a shoe company that sells online. They will store customer data across multiple databases depending on which data is stored when a customer orders shoes online. The columns in the Customer table could include Customer ID and Mailing Address as well as Purchase ID and Purchased Item ID. Columns in the Marketing table could include Customer ID, Transaction Amount, Purchase ID, Promotional Campaign, Customer ID, and Purchase ID.

This simplified database shows Customer ID as the primary and foreign keys. We can now see the effect of marketing on sales generation.
