Oracle vs PostgreSQL: What are the differences?
Oracle and PostgreSQL are popular relational database management systems (RDBMS) known for their robust features and scalability. Here are the key differences between Oracle and PostgreSQL:
Licensing and Cost: One of the primary differences between Oracle and PostgreSQL is the licensing and cost structure. Oracle is a commercial database and comes with a significant licensing cost, especially for enterprise-level deployments. In contrast, PostgreSQL is open-source and free to use, making it a more cost-effective choice for organizations with budget constraints or smaller-scale projects.
Performance and Scalability: Oracle is known for its robust performance optimizations and advanced features like in-memory computing and real application clusters (RAC), which allow for horizontal scalability and high availability. PostgreSQL, on the other hand, offers excellent performance and scalability capabilities but may require additional configuration and optimization for specific use cases.
Data Replication and High Availability: Oracle provides robust built-in replication and high availability features. These features enable real-time data replication and failover capabilities for ensuring high availability and disaster recovery. PostgreSQL also offers replication capabilities through streaming replication and logical replication, but it may require more configuration and setup compared to Oracle's comprehensive solutions.
Ecosystem and Community: Oracle has a well-established ecosystem with a large community of users and extensive third-party tooling and support. It offers a wide range of integrated products, including middleware, analytics, and business intelligence tools. PostgreSQL has a vibrant and growing community, with a rich ecosystem of extensions and frameworks. While PostgreSQL's ecosystem is not as extensive as Oracle's, it is continuously expanding, and there are numerous tools and frameworks available for different use cases.
SQL Compatibility: Oracle has its own SQL dialect, known as Oracle SQL, which includes proprietary features and extensions. PostgreSQL adheres more closely to the SQL standard and offers advanced SQL features like Common Table Expressions (CTEs) and window functions. Developers familiar with Oracle SQL may need to adjust their queries and code when migrating to PostgreSQL.
In summary, Oracle offers advanced features, scalability, and a comprehensive ecosystem but comes with a significant licensing cost. PostgreSQL, being open-source, provides cost-effectiveness, flexibility, and a growing community.
Fauna is a serverless database where you store data as JSON. Also, you have build in a HTTP GraphQL interface with a full authentication & authorization layer. That means you can skip your Backend and call it directly from the Frontend. With the power, that you can write data transformation function within Fauna with her own language called FQL, we're getting a blazing fast application.
Also, Fauna takes care about scaling and backups (All data are sharded on three different locations on the globe). That means we can fully focus on writing business logic and don't have to worry anymore about infrastructure.
We have chosen Tibero over Oracle because we want to offer a PL/SQL-as-a-Service that the users can deploy in any Cloud without concerns from our website at some standard cost. With Oracle Database, developers would have to worry about what they implement and the related costs of each feature but the licensing model from Tibero is just 1 price and we have all features included, so we don't have to worry and developers using our SQLaaS neither. PostgreSQL would be open source. We have chosen Tibero over Oracle because we want to offer a PL/SQL that you can deploy in any Cloud without concerns. PostgreSQL would be the open source option but we need to offer an SQLaaS with encryption and more enterprise features in the background and best value option we have found, it was Tibero Database for PL/SQL-based applications.
