Relational Databases
Considered the most mature of all databases, these databases lead in the production line along with their management systems. In this database, every piece of information has a relationship with every other piece of information. This is on account of every data value in the database having a unique identity in the form of a record.
Note that all data is tabulated in this model. Therefore, every row of data in the database is linked with another row using a primary key. Similarly, every table is linked with another table using a foreign key.
Refer to the diagram below and notice how the concept of ‘Keys’ is used to link two tables.
Due to this introduction of tables to organize data, it has become exceedingly popular. In consequence, they are widely integrated into Web-Ap interfaces to serve as ideal repositories for user data. What makes it further interesting is the ease in mastering it, since the language used to interact with the database is simple (SQL in this case) and easy to comprehend.
It is also worth being aware of the fact that in Relational databases, scaling and traversing through data is quite a light-weighted task in comparison to Hierarchical Databases.
Types of Databases
A quick review of the present need to store massive chunks of data relevant to multiple related or unrelated categories, reveals that databases must be highly effective at what they are designed to do.
This is not only because of the amount of data being continuously revised or modified that we are dealing with the dynamics of it aren’t of sole interest anymore. It’s because of the social value that every individual has assigned to them: databases are the literal backbone of a client’s lifestyle or a business’s worth.
Designing different types of databases lies at the core of the functionality that they provide to the users. Since data is a dynamic entity, the way it is stored varies a lot. It is also the reason behind companies designing their own types of databases that comply with their needs. In this article, we will be discussing the types of Databases in detail.
