An Overview of Migrating Databases from Oracle To Postgres

Before going into the reasons and benefits of migrating databases from Oracle to Postgres, let us understand the need for this procedure.

Database migration is the activity where you move databases from a source to a target. There are several reasons that make it necessary for organizations. First, and this is very important in the modern business scenario, migration leads to significant savings when databases are moved from a high-cost platform to a lower-cost one.

Other reasons for migrating databases are upgrading to a more efficient platform such as the cloud, consolidating databases, or changing the database schema.

In this post, we will evaluate in detail some of the critical reasons for migrating databases from Oracle to Postgres and the benefits that this activity brings to the table.

Why Should You Migrate Databases From Oracle to Postgres

There are three main reasons why it makes sense for organizations to move databases from Oracle to Postgres.

1. Cost-savings: Users have to pay license costs to Oracle to use the database platform. Charges for partitioning and high availability further add to the cost. On the other hand, Postgres is open-source and free to use.

2.Flexibility: Users always face the possibility of vendor lock-in from Oracle. However, this is not the case with Postgres as it is an open-source licensing platform that is freely available from public cloud providers such as AWS (Amazon Web Service).

3.  Personalized Experience: Because of the open-source format of Postgres, it offers countless extensions that can be freely used without fees to increase the performance of the database. Oracle, on the other hand, charges users upfront for add-ons that boost its functioning.

However, migrating databases from Oracle to Postgres is not simple and can be a very time-consuming and challenging task since it entails moving data between two Relational Database Management Systems (RDMS).

Benefits of Moving Databases From Oracle to Postgres

Now let us go to the benefits of this form of database migration.

1.  Application Programming: Even though both Postgres and Oracle offer an API for database communication, it is easier to access any function of Postgres. This is because Postgres is open-source and a header file can be included in the project.

2.   Extensibility: The Postgres extension system is supported by the general community, thereby giving access to thousands of available plug-ins. Oracle, on the other hand, has a proprietary plug-in system.

3. Localization: Automatic character coding and collation support is provided by the Postgres localization system services while Oracle provides globalization support tools. These include a globalization development kit and Unicode character support.     

These are some of the reasons and benefits that make migrating databases from Oracle to Postgres such an attractive proposition for businesses around the world. The main advantage here is that Postgres is an open-source platform with free access to the public cloud, attributes that are not present in the Oracle DBMS.
