Databases & Data Storage
PostgreSQL
Definition
PostgreSQL, also known as Postgres, is a free and open-source relational database management system (RDBMS) emphasizing extensibility and SQL compliance.
Why It Matters
PostgreSQL is known for its robustness, advanced feature set, and strong adherence to SQL standards. It is often considered the most advanced open-source relational database and is a favorite among developers who need more advanced data types and features than MySQL provides.
Contextual Example
A geospatial application might use PostgreSQL with its PostGIS extension, which provides powerful features for storing and querying geographic data.
Common Misunderstandings
- PostgreSQL is highly extensible, allowing users to define their own data types, functions, and operators.
- It is often seen as a more powerful, though potentially more complex, alternative to MySQL.
