• ACID Properties: ACID properties stand for: Atomicity, Consistency, Isolation, and Durability. This implies that transactions can be processed reliably, even in case of  system failures.
• SQL Support: PostgreSQL supports various SQL commands, making it compatible with various data manipulation applications and tools.
• Extensibility: Developers can create operators, unique data types, functions, and even entire programming languages to extend the database's capabilities to meet specific use cases.
• Relational Database Management: PostgreSQL follows the relational database model, which means an organization of data into tables with rows and columns. Relationships between tables are established using keys, allowing for efficient data storage and retrieval.
• Triggers: Developers can define triggers and stored procedures within the database, automating actions and implementing business logics directly in the database itself.
• Concurrency: Multi-version concurrency Control allows multiple transactions to take place at the same time without causing any data conflicts or errors.

Importance of PostgreSQL

Because of its excellent capabilities, dependability, and flexibility, PostgreSQL has received a worldwide reputation and acceptance. Some of the key points are as follows:

• Standard Compliance: PostgreSQL follows ANSI SQL standards and supports a variety of SQL capabilities. This interoperability enables PostgreSQL-based apps to be more likely to be transferable across other database systems.
• Robust: PostgreSQL has a track record of excellent critical data handling for applications ranging from small enterprises to major corporations.
• Indexing: It provides various indexing strategies that optimize query performance and speed up data retrieval for applications that require fast results.
• Full-Text Search: Full-text search functionality is crucial for applications requiring extensive text-based search capabilities, such as e-commerce platforms or content management systems.
• Geospatial Capabilities: PostgreSQL is a way better choice for applications requiring geographic information systems and location-based services because of its built-in support for geospatial data.
• Versatility: PostgreSQL's versatility suits it for a wide range of applications, including web development, corporate intelligence, data warehousing, and scientific research and much more.
