When choosing a database for your application, the debate between relational and non-relational database is crucial. Understanding the differences between the two can help you decide.
Relational database:
Relational database such as MySQL, PostgreSQL, and Oracle, store data in table format with predefined schemas. Structured Query Language (SQL) is used for querying and managing data. Relational databases have a great ability to maintain data integrity and support complex queries. They stand out in transactions that require Atomicity, Consistency, Isolation and Durability, making them ideal for applications requiring structured data and data integrity, such as financial systems and inventory management.
Advantages:
Relational databases ensure accuracy and consistency of data through constraints and relationships between tables.
A detailed data analysis can be performed as the complex joins and transactions are supported by Relational databases.
SQL is a well-established and standardized query language ensuring that you receive the resources required for a successful development.
Non-relational database:
Non-relational databases are also known as NoSQL database, such as MongoDB, Cassandra, and Redis. These databases are designed to be flexible and scalable storage for unstructured data. NoSQL databases can store various types of data, such as documents, key-value pair, and graphs. These databases are optimized for horizontal scaling, making them suitable for handling rapidly changing data, such as big data applications and real-time analytics.
Advantages:
NoSQL databases scale horizontally to accommodate growing data.
Without needing a fixed schema various type of data can be stored.
Non-relational databases are optimized for fast data retrieval and throughput.
The requirements of your projects directly affect the choice of the database for your application. Relational database might be the best fit for your application if you require strong data consistency, complex querying capabilities, and established standards. Non-relational database could be more suitable for the application that demand flexibility, scalability, and handle a diverse range of data.
