Types of Databases

✅ Relational Databases (SQL):
Relational databases are table and relationship based to store data effectively. They are appropriate for applications with complex queries and data persistence.

✅ Non-Relational Databases (NoSQL):
NoSQL databases handle unstructured data like documents, keys, and values. They support greater flexibility for storing various data like text and images, and they can easily be horizontally scaled.

✅ Key Considerations:
  • SQL Databases: Allow structured and safe data handling, appropriate for exact and consistent data handling.
  • NoSQL Databases: Support rapidity and ease in processing large, unstructured data sets.

Relational Databases (SQL)

Relational databases use a table-based model to store data, making it easy to organize and retrieve data.
  • Table Model: Storing data in rows and columns.
  • Complex Queries: Complex queries are supported by SQL language.
  • Integration and Consistency: Data integrity is maintained as well as accuracy.
  • High Performance: Efficient processing of big, complex data sets.
  • Access Control: Provides security levels for access control.
💯 SQL databases are ideally suited for applications that require fast and reliable management of structured data, with powerful analysis and retrieval capabilities.

Non-Relational Databases (NoSQL)

NoSQL databases offer a different paradigm from the traditional table-based systems, with a focus on unstructured data and scale.
  • Data Variety: Provides multiple types of data, such as documents, graphs, and key-value pairs.
  • Flexibility: Supports flexible schema for horizontal scaling and supports large amounts of data.
  • High Performance: Suitable for high-speed write and read operations.
  • Scalability: Horizontal scaling is easily supported due to its design.
  • Versatility: Suitable for modern applications like social networks and big data analytics.
💯 NoSQL databases are ideal for applications that require flexibility in managing unstructured data or high performance with scalability.

Popular Database Management Systems

Below are some of the most used DBMS, offering varying solutions based on business needs:
  • MySQL: Open-source database with a comfortability reputation of being easy and efficient in data handling.
  • PostgreSQL: Is endowed with strong search and query abilities, and is thus best suited for complex data.
  • Microsoft SQL Server: Possesses high-performance and analytic tools, utilized most in large business settings.
  • MongoDB: NoSQL database that supports the storage of unstructured data with ease and velocity.
Note: The choice of the right DBMS depends on your individual requirements, whether it is high performance, flexibility, or technical support.
