PostgreSQL is the world’s most advanced open source database. Developed over 25 years by a vibrant and independent open source community, PostgreSQL was born from the same research as Oracle and DB2 and contains comparable enterprise-class features such as full Atomicity, Consistency, Isolation, Durability (ACID) compliance for outstanding transaction reliability and Multi-Version Concurrency Control (MVCC) for supporting high concurrent loads.
PostgreSQL supports standards such as ANSI SQL and SQL/MED, including foreign data wrappers (FDW) for remote data sources such as MySQL, MongoDB and many others, and yet is highly extensible with support for over 12 procedural languages, GIN and GIST indexes, geospatial data, and NoSQL for document (JSON) and key-value-based applications.
EDB Postgres Advanced Server continually integrates each major, minor and security release of community PostgreSQL and then adds enterprise security, performance, manageability, development and database compatibility for Oracle designed for large enterprise requirements. EDB Advanced Server's compatibility allows existing Oracle users to move their applications to a lower cost alternative while preserving their investment in Oracle code, skills and practices.
EDB Tool Suites
The EDB Tool suites for integration, management, and migration make your databases highly available, faster and easier to manage, and allow integration with other data sources. A free trial of EDB Postgres Enterprise Manager, EDB Postgres Replication Server, EDB Postgres Backup and Recovery, and EDB Postgres Migration Toolkit are included in either the PostgreSQL or EDB Postgres Advanced Server downloads - after the database installs, run StackBuilder (Plus) and look for EDB tools.
