Oracle ETL

Data warehouses and business intelligence derived from them are a very critical aspect of the modern business world. ETL is the process of populating the data warehouses by extracting data from various sources, transforming them into usable forms, and loading them to destinations.

Having the data from all these sources at one single point helps businesses to combine, aggregate, and analyze them to form insights that can lead to cost savings or higher revenue. Some of the sources needs specially designed tools like Oracle ETL tools for managing the flow of data in the Oracle Database.

This article introduces you to the best tools for Oracle ETL.

Key Featured of Oracle Data Integrator

  • Oracle Data Integrator is Oracle’s own product for everything related to Oracle ETL as a source or destination. It is available as an on-premise solution or cloud-based solution.
  • ODI is enterprise-grade with well-endowed security and compliance structures.
  • Oracle Data Integrator supports most of the on-premise databases like SQL Server, Postgres, etc. as source and destination. Since it supports JDBC drivers, even the cloud databases that support JDBC are supported by ODI.
  • Transformations are executed mainly using Oracle queries and exploit the Oracle execution engine.
  • Recent developments have also brought in real-time data capability to ODI.
  • It natively supports change data capture and real-time replication based on Oracle’s own tools like Golden Gate. 
  • Support for SaaS offerings is limited in ODI.

Use Case of Oracle Data Integrator

ODI makes a strong case if your primary data source or destination is Oracle. If your organization uses a wide variety of databases and Oracle is just one of them, then it is better to look elsewhere since the support for SaaS offerings and other upcoming databases is limited in ODI.

That said, it provides enterprise-grade security and compliance structures. So if your organization’s architecture is primarily an on-premise Oracle-based one, ODI should feature in your list of most preferred tools.

Pricing

Oracle Data Integrator on-premise pricing is not publicly disclosed and is done under negotiated contracts. ODI Cloud starts at 1.2 $ per GB per hour.

3) Apache Airflow

Key Features of Apache Airflow

  • Airflow is an open-source ETL tool that is primarily meant for designing workflows and ETL job sequences.
  • Airflow is meant as a batch processing platform, although there is limited support for real-time processing by using triggers.
  • Airflow supports a wide variety of sources and destinations including cloud-based databases like Redshift.
  • Airflow connectors are based on plugins. Since it is open-source, it is possible to develop custom plugins and deploy them on-premise. Airflow has a strong community that keeps on adding connector plugins and thus supports the popular SaaS offerings too.

Use Case

Airflow is primarily meant for companies with teams that can maintain their infrastructure and code. Airflow is typically deployed on-premise and is not available as a completely managed solution.

If your organization has interests in a variety of sources and destinations and wants to maintain close control over the code and infrastructure using its own employees, Airflow is a good choice.

Pricing

Airflow is free to use and customize. Infrastructure and development costs are the only costs involved in using Airflow.

4) Informatica Power Center

Key Features of Informatica Power Center

  • Informatica Power Center is primarily an on-premise ETL tool that can integrate with a variety of databases. Oracle is well supported.
  • Like Oracle Data Integrator, Informatica Power Center is enterprise-grade with support for data masking, master data management, etc.
  • Support for cloud-based databases is higher in Informatica Power center when compared to Oracle Data Integrator. Databases like Redshift and DynamoDB are supported.
  • It is meant for batch-based operation.
  • It is also available as a cloud platform as a pay-as-you-go model where tasks will be executed using cloud infrastructure. 

Use Case

Power center makes a strong case for organizations that prefer on-premise architectures where Oracle is just one of the sources and with strict enterprise-grade security requirements. 

Pricing 

Pricing is based on negotiations and established contracts. The cloud version starts at $2000 per month for its most basic plan. Cloud providers like AWS and Azure provide this as a completely managed service on a pay-as-you-go model. 

5) AWS Glue

Key Features of AWS Glue

  • AWS Glue is a completely managed ETL solution from Amazon that supports a variety of databases through custom drivers and JDBC drivers. Since Oracle supports JDBC drivers, Glue can connect to Oracle as well.
  • It provides an execution engine based on spark.
  • Glue can execute batch-based workloads and near real-time workloads. Glue works based on crawlers which can trigger jobs based on data availability. It can automatically discover data and catalog them.
  • Using Glue and AWS Lambda functions, a completely serverless ETL pipeline can be implemented.
  • The major limitation here is the lack of support for non-AWS-based databases. Support for SaaS offerings is also not great.

Use Case

Glue fits well in scenarios where the organization is primarily AWS-based and Oracle is just one of the data sources. Organizations with strict on-premise data requirements can not use Glue since it is a completely managed service. 

Pricing

Pricing for Glue starts from $ 0.44 per data processing unit per hour. Each data processing unit is a 4 core CPU with 16 GB of memory.

6) StreamSets

Key Features of StreamSets

  • StreamSets is a real-time data processing tool with excellent monitoring capabilities. It markets itself as a data ops tool.
  • StreamSets’ data collector can connect to a variety of sources including Oracle. A full set of supported sources and destinations can be found here.
  • StreamSets’ data protector can help an organization stay within major compliance requirements like HIPAA and GDPR.
  • StreamSets does not do a good job of supporting major SaaS offerings.
  • Like AWS Glue, it is also based on a spark execution engine and hence your source and destination database’s execution power is not much used.

Use Case

StreamSets can be a good choice where the use case is primarily real-time based and the organization is open for a completely managed cloud service. Since the support for SaaS offerings is limited, it is better in scenarios where sources and destinations are primarily traditional databases. 

Pricing

StreamSets’ pricing strategy is not transparent and is agreed upon via negotiated contracts.

Factors that Drive the Decision of Oracle ETL Tools

The question of how to evaluate the above Oracle ETL tools, to find the one that is the best fit for your use case does not have a straightforward answer. The decision of choosing the right Oracle ETL Tools depends on a lot of criteria as listed below:

  • Ease of Setup and Implementation: This factor plays an important role in your time to production. Cloud-based Oracle ETL tools offer the best value in this regard since there is no setup and implementation time involved.
  • Integration Support for Various Data Sources and Destinations: The flexibility of an Oracle ETL is all about aggregating data from a wide variety of sources. Once an ETL tool is chosen, changing that requires a lot of time and effort. Hence it is imperative that the Oracle ETL tool that you choose has support for all your future data source requirements.
  • Monitoring and Job Management: ETL frameworks work day and night executing jobs and are always in a race against time to finish the jobs within the service level agreements. Timely identification of problems and status reporting is very important in maintaining the stability of the pipeline.
  • Real-time Data Processing: Modern Oracle ETL pipelines are fastly moving towards real-time data processing. Support for real-time data streams must be considered at least for future-proofing the ETL pipeline.
  • Support for Data Transformations: Data from various sources needs to be transformed into an easily analyzable and searchable form before pushing to the data warehouse.
    As time progresses, business analysts will dig up more and more metrics that denote the success or failure of their business. Generating these metrics will involve complex transformations and these will also become part of the Oracle ETL Data Pipeline jobs.
  • Support for Various Replication Measures: It is a common practice to replicate various staging views and destination views for logically separating the different jobs. Your ETL framework should have the ability to support such replication out of the box.
  • Data Load Reliability: The last part of ETL, loading data into the destination warehouse is very closely coupled with the choice of the Oracle ETL platform. Your chosen platform must be able to reliably load data to your target database and recover from unexpected failures.
  • Ease of Use: Configuring new ETL jobs and testing them is a big part of the lifecycle of ETL frameworks. Frameworks with support for simple UI-based ETL job design can prove to be very easy to use and enable the lowest time to production.
