Migrate from Oracle to PostgreSQL Database

Oracle is one of the most popular and largest relational database management system however, due to its high price tag and complexity, many enterprises are making a move from Oracle database to open-source databases like PostgreSQL.

PostgreSQL is the most advanced open-source database which is designed to store and secure the data of companies. It was awarded as the "Database System of the Year" several times. PostgreSQL is a highly stable, secure, and scalable database system, and has a strong focus on continuous development, reliability, cutting-edge technology, and user requirements. As such, it has established itself as a leading player in the open-source database world and challenging popular players such as IBM, Oracle, and Sybase.

PostgreSQL help companies reach the next level of advanced database technology, including Data Warehouse Analytics, Machine Learning, Cloud Services, IoT, and Data Science. Leading companies in the world are using PostgreSQL as it helps reduce the total cost of ownership up to 80%.

Here, we discuss the main reasons why companies are interested in migrating from the Oracle database to PostgreSQL database.

Why Migrate from Oracle to PostgreSQL?

1. Starting is easy

PostgreSQL is simple and easy to start. Developers can leverage amazing official documentation and publicly available data on the forums and other platforms where the PostgreSQL developer community meets. All patches submitted to PostgreSQL must have documentation that adheres to high community standards and will use that material to create excellent official documentation.

2. PostgreSQL is an Open-Source Database

Since PostgreSQL is an open-source solution, it gives you portability and flexibility. PostgreSQL Global Development Group leads the project which is designed with community members designated from a variety of backgrounds where each person is committed to maintaining Postgres' openness. Migrating from Oracle or another commercial solution to PostgreSQL can help you avoid vendor lock-in and license costs. Tapping vendor support for PostgreSQL is also easy, or free to switch to a new vendor support provider when advantageous.

3. Licensing and Community are Open

In a digitized world where every open-source license is not as open as you like, a PostgreSQL license will never disappoint you. PostgreSQL Global Development Group requires attribution for all submissions, so anything that goes into the database migration project will go directly into your installation without any inconvenience. It enables you to participate in all improvements without any additional licensing costs.

4. PostgreSQL is Extensible

PostgreSQL database is absolutely extensible. There are two facilities for the PostgreSQL extension. First, the developers’ team can create and use standalone packages called "extensions" without any modification needed to PostgreSQL. The PostgreSQL extension network helps you get started with the project. The other way to extend PostgreSQL is by contributing directly to the PostgreSQL project. Contributors are welcome and very sought after. If you feel that your addition to the product is compelling, you can contact PostgreSQL Global Development Group (PGDG) by just subscribing to the pgsql-hackers mailing list on the website, postgresql.org.

5. Postgres is Similar to Oracle

For businesses accustomed to Oracle, the PostgreSQL database is no stranger to offering database functionalities to the company. Functions, indexes, operations, and structure are instantly identified. Both PostgreSQL and Oracle affect the same multi-version synchronization control in their data storage strategies, which can predict transaction behavior and risk management in each. And, if you want PostgreSQL processes to look like Oracle, available extensions can help you do that simply.
