The PGSQL reputation for flexibility and data integrity makes it the relational database management system (RDBMS) of choice for giants like Apple, NASA, Spotify, Reddit, Instagram, and the Internet Movie Database (IMDb). PostgreSQL offers robust storage features scalable for any sized dataset with SQL and JSON querying. PGSQL stores documents and primitive, structured, or custom data types. Multiversion concurrency control (MVCC), synchronous replication, and multiple index formats make information retrieval dependable and quick. Standby servers give PGSQL high availability. A permissive license and procedural languages let developers extend functionality as needed. Per-role access and external authenticator support keeps data secure.
PostGreSQL is an online transactional processing (OLTP) database to retain, retrieve, and update information. Ease of use and cost effectiveness make it the top data warehouse and LAMP stack option for large companies and individuals. High performance is the result of continuous development, an active userbase, and extensive functions.
PostGre connects to other applications via interfaces written in C. Third party libraries for Python, Java, Node.js, C++, Go, and Rust maximize alternative app connectivity options. Tables act as proxies to connect with external databases. Foreign data wrappers (FDWs) scrape external databases for information when queried and return multiple results together. Materialized and recursive views subset queried data for optimal responsiveness.
Multi-version concurrency control (MVCC) allow multiple transaction processes to access the database simultaneously. Triggers written into data manipulation language (DML) or data definition language (DDL) statements validate the information for partitioning. Write ahead logging (WAL) and savepoints give data stores fault tolerance. Meanwhile, transport layer security (TLS) encryption and multi-factor authentication (MFA) ensure security.
PGSQL supports numerous native data types and the creation of custom data types, including subroutines, indexes, and conversions, using source code modification. Solutions to specific problems are Implemented with custom functions. These in-house builds avoid database recompilation before deployment.
Ntegral certified images are always up-to-date, secure, and built to work right out of the box.
Ntegral packages applications following industry standards, and continuously monitors all components and libraries for vulnerabilities and application updates. When any security threat or update is identified, Ntegral automatically repackages the applications and pushes the latest versions to the cloud marketplaces.
