Before going into the benefits of migrating an Oracle database to cloud-based Snowflake, a look at the two will be in order.

Oracle database helps in quick and easy storage and retrieval of data and runs on a wide range of hardware. The matchless integration of applications in the Oracle database is facilitated by its networking stack feature. Oracle database was one of the first of its kind to have provided support to GNU/LINUX and is also ACID-compliant. This guarantees data reliability and integrity.

Now, what is the need for organizations to migrate database from Oracle to Snowflake?

Snowflake is a recently-introduced cloud-based data warehousing solution that is offered as a SaaS (Software-as-a-Service) product. Its architecture is built not on any existing database or “big data” software but exclusively in the cloud only. Hence, there is no need for businesses to install or configure any additional hardware or software whenever there is a rise in demand for resources as all maintenance and tuning issues are directly taken care of by Snowflake.

Benefits of migrating data from Oracle to Snowflake

There are several benefits of Snowflake for which organizations want to migrate data from Oracle database.

· Snowflake is a data warehousing solution that offers users a high degree of flexibility and elasticity in storage and computing facilities. Businesses can scale up or down in data storage and usage by paying only for the quantum of resources used.

· It is possible to work with both structured and unstructured data in Snowflake, a feature that is not present in the Oracle database.

· Snowflake is a high-performing platform offering users unmatched computing facilities. Several users can simultaneously execute multiple intricate queries without facing any lag in speeds or drop in performance.

· Organizations can have their new data processing projects and analytics up and running quickly without investing in hardware or software as Snowflake is a fully managed service.

All these benefits of a cloud-based service are the reasons why businesses are opting more and more to migrate databases from Oracle to Snowflake.

Migrating database from Oracle to Snowflake

Migrating database from Oracle to Snowflake is a four-step process that is largely automated.

· The first step is to extract the data and place it in a CSV file. This is done through a SQL Plus query tool installed in the Oracle Database Server. The data extraction logic is done in the Shell Script.

· This data has to be processed and formatted to a type that matches what is accepted by Snowflake architecture before it can be loaded onto the platform.

· The formatted data has to be kept in a cloud-staging area which might be an internally created table or an external location such as Microsoft Azure or Amazon S3

· The final stage is loading the data from the staging area to Snowflake.
