Method 1: Migrating Data from Firebird to Oracle Using the Manual Method
- Data Export: Export data from Firebird using tools like isql or custom scripts to extract data in a suitable format.
- Data Transformation: Transform the exported data to match Oracle’s schema and data types, ensuring compatibility.
- Schema Creation: Manually create the corresponding tables, indexes, and constraints in Oracle to mirror the Firebird schema.
- Data Import: Use Oracle tools like SQL*Loader or direct SQL inserts to import the transformed data into Oracle.
- Validation: Validate the migrated data by comparing record counts and sample data between Firebird and Oracle.
- Testing: Perform thorough testing to ensure that the data migration is successful and that applications function correctly with the new Oracle database.
Disadvantages of Migrating Data from Firebird to Oracle Using the Manual Method
- High Error Risk with lot of manual efforts
- Difficult in achieving Data Transformation
- Dependency on tech resources
- No Automation
- Limited Scalability
- For every table, this work has to be done.
- No automated methods of handling errors, notifications
- No automated methods of roll back in case
- No automated direct methods of logs and knowing amount of data transferred
- No automated direct methods in case if you would like to have methods like incremental load (Change Data Capture)
Method 2: Migrating Data from Firebird to Oracle Using ETL Tools
There are various advantages which ETL
- Data Extraction: ETL tools can automatically extract data from Firebird using connectors or custom queries, simplifying the extraction process.
- Data Transformation: The ETL process allows for automated transformation of data, including converting data types, cleaning, and restructuring data to match Oracle’s schema.
- Data Loading: The ETL tools efficiently load transformed data into Oracle, ensuring compatibility with the target database’s structure.
- Error Handling: Most ETL tools include error handling features, which automatically detect and log issues during migration, reducing the risk of data corruption.
- Automation and Scheduling: ETL tools offer the ability to automate and schedule migration tasks, saving time and reducing manual intervention during the process.
- Scalability and Efficiency: ETL tools are designed to handle large volumes of data, making them more scalable and efficient than manual methods, especially for ongoing migrations or large datasets.
Challenges of Using ETL Tools for Data Migration:
- Complex Setup and Configuration in case of on-premise deployment
- Steep learning curve to use these tools
- Dependency on using highly technical resources/ Data Engineers to do this kind of work
- Cost
- Scalability Issues
- Limited Customization
- Maintenance Overhead

Below are the steps to do the data migration activity
Step 1: Connect to Firebird(which acts as source)
Step 2 : Connect to Oracle (which acts as target)
Step 3: Create a new job. Select your source (Firebird) and select which all tables you would like to migrate.
Step 4 (OPTIONAL): If you would like to do any other tasks like data type conversion, data cleaning, transformations, calculations those also you can instruct to do in natural English. NO knowledge of SQL or python or spark etc required.
Step 5: Orchenstrate/schedule this. While scheduling you can run it as one time load, or change data capture or truncate and load etc.
For more advanced users, Ask On Data is also providing options to write SQL, edit YAML, write PySpark code etc.
There are other functionalities like error logging, notifications, monitoring, logs etc which can provide more information like the amount of data transferred, logs, any error information if the job did not run and other kind of monitoring information etc.
