    PostgreSQL: The Architecture of Data Integrity and History

    Bestes Zitat aus PostgreSQL: The Architecture of Data Integrity and History

    “

    PostgreSQL is built on a philosophy of extensibility and strict data integrity, utilizing a multiversion concurrency control model where reads don't block writes. It’s not just a place to dump data—it’s an engine designed to manage it intelligently.

    Häufig gestellte Fragen

    PostgreSQL began as the POSTGRES research project at the University of California, Berkeley, over thirty years ago. Originally designed in the mid-eighties to move beyond traditional relational models, it pioneered complex data types and rule systems. This deep academic heritage provided the foundation for what has become a massive, open-source database engine that powers a significant portion of the modern internet today.

    While the original POSTGRES project focused on advanced data models, it was not always the SQL giant it is today. In 1994, two graduate students added a SQL language interpreter to the system, launching the Postgres95 era. This pivotal development allowed the project to evolve into the PostgreSQL Global Development Group, combining its advanced architectural roots with the widely used SQL language.

    PostgreSQL is built on a core philosophy of extensibility and strict data integrity, making it a rock-solid choice for managing complex data. Its architecture allows it to be both flexible and reliable, a rare combination in database management. Because it has been battle-tested in the real world for decades, it offers a stable environment for developers starting new projects or migrating existing data systems.
