Postgresql Vs Oracle

One of PostgreSQL’s strong points is extensibility, allowing users to develop their own data types or functions. Additionally, it has countless features related to internationalization, data types, text search, data integrity, disaster recovery, concurrency, extensibility, performance, reliability, and security. PostgreSQL runs on all major operating systems , has been MongoDB vs PostgreSQL ACID-compliant since 2001, and has powerful add-ons such as the popular PostGIS geospatial database extender. It is no surprise that PostgreSQL has become the open source relational database of choice for many people and organizations. Expert developers and commercial enterprises who understand the limitations of traditional database systems heavily support PostgreSQL.

It’s been around since 1979, but its popularity has been decreasing, as we can see in the previous section, where it ranks in the 8th position in the developer’s preferences, way behind PostgreSQL. The decrease in popularity can be connected to the increasing adoption of open-source databases like PostgreSQL by developers and businesses due to their robustness and low costs. Deploying open source database management technology offers unique benefits to enterprises, including better costs, higher flexibility, and innovation not always available with proprietary database solutions. Developed by a diverse group of contributors, PostgreSQL builds on a strong foundation of knowledge, expertise, and open source values, making it the world’s most advanced database. In larger database systems where data authentication and read/write speeds are essential, PostgreSQL is hard to beat. PostgreSQL supports a variety of performance optimizations typically found only in proprietary database technology, such as geospatial support and unrestricted concurrency.

Community

Whether your app works with financial data, website analytics, IOT data, ad tech, or any other type of monitoring data—time series workloads often need to grow beyond the memory, compute, and disk of a single node. By scaling out Postgres across multiple nodes, Citus gives your analytics dashboards the compute, memory, and performance they need to process billions of events in real time. Customer-facing real-time analytics dashboards need to deliver sub-second query responses to 1000s of concurrent users, while simultaneously ingesting fresh data and enabling users to query the fresh data in real time, too. Being hosted in an on-premises environment or inside a cloud provider, PostgreSQL can handle large amounts of data and grow without affecting query performance and data integrity. Document-based databases process data as JSON-type documents and store them inside collections. As a result, the data structure is not rigid like traditional relational databases – this means that the database can give a higher level of flexibility when it comes to the data structure.

From user authentication to secure TCP/IP connections, PostgreSQL offers multiple security mechanisms that combined can protect data in a highly effective way. It enjoys the robustness of a large global community of users that work around the clock developing the package and tools to go with it. MongoDB can scale horizontally due to its distributed architecture where multiple components collaborate across platforms, while PostgreSQL scales vertically. MongoDB is a NoSQL database and stores documents inside collections, while PostgreSQL is a relational database and stores records inside tables. As we saw in the previous section, PostgreSQL is the second most popular database among developers, and the competition is fierce.

Web Applications

With the wide adoption of web applications, most websites need to handle hundreds of thousands of requests per second and still be responsive while delivering data to all their customers. PostgreSQL can offer the capacity to respond to that magnitude of request and still handle terabytes of data with one single instance. In our new Decision Maker’s Guide to Open Source Databases, our experts break down the top open source databases in use today, including the most popular open source RDBMS.

Features

With the use of extensions, procedural languages can also be used for development in many other programming languages, including Perl, Python, JavaScript, and Ruby. Developers experience a number of benefits when using PostgreSQL in enterprise database deployments. PostgreSQL comes packed with an abundance of rich features and extensions to create highly scalable and easy-to-administer databases while providing seamless replication and concurrency across multiple computing environments. PostgreSQL is hardware-agnostic, and vertical scalability is achieved through solid mathematical algorithm choices in the query engine and efficient management of the memory and file system blocks. PostgreSQL can be scaled horizontally through different approaches to partitioning, sharding, geo-location, or replication. Our expert support team can help with customer questions around scaling.

Security.Postgres offers a variety of security mechanisms, including user authentication and/or secure TCP/IP connections, all of which protect data in a high-performance way. Postgres supports multiple programming languages and protocols, such as Ruby, Python, .Net, C/C++, Go, Java, ODBC.
