TL;DR
This can be done by building a data pipeline manually, usually a Python script (you can leverage a tool as Apache Airflow for this). This process can take more than a full week of development. Or it can be done in minutes on Airbyte in three easy steps:
- set up MongoDb as a source connector (using Auth, or usually an API key)
- set up Oracle as a destination connector
- define which data you want to transfer and how frequently
You can choose to self-host the pipeline using Airbyte Open Source or have it managed for you with Airbyte Cloud.
This tutorial’s purpose is to show you how.

- Select the sync mode for your streams: Choose between full refreshes or incremental syncs (with deduplication if you want), and this for all streams or at the stream level. Incremental is only available for streams that have a primary cursor.
- Test your connection: Click the 'Test Connection' button to make sure that your setup works. If the connection test is successful, save your configuration.
- Start the sync: If the test passes, click 'Set Up Connection'. Airbyte will start moving data from MongoDb to Oracle according to your settings.
Remember, Airbyte keeps your data in sync at the frequency you determine, ensuring your Oracle data warehouse is always up-to-date with your MongoDb data.
Method 2: Connecting Mongodb to oracle db manually
Moving data from MongoDB to Oracle Database without using third-party connectors or integrations involves exporting the data from MongoDB, transforming it into a format that Oracle can understand, and then importing it into the Oracle Database. Below is a step-by-step guide to achieve this:
Step 1: Export Data from MongoDB
1. Identify the Data to Export: Determine which collections you need to export from MongoDB.
2. Use `mongoexport`: Use the `mongoexport` utility to export the data from MongoDB to a JSON or CSV file. This tool is part of the MongoDB server installation.
For JSON:
```sh
mongoexport --db yourDatabaseName --collection yourCollectionName --out yourData.json
```
For CSV (you'll need to specify the fields):
```sh
mongoexport --db yourDatabaseName --collection yourCollectionName --type=csv --fields field1,field2 --out yourData.csv
```
Step 2: Prepare the Data for Oracle
1. Review Data Types: Check the MongoDB data types and map them to the corresponding Oracle data types.
2. Transform Data: If needed, write a script (in a language like Python, Perl, or even a shell script) to transform the data from the MongoDB export into a format suitable for Oracle. This may include:
- Converting BSON ObjectId to a string.
- Formatting dates to match Oracle's date format.
- Handling nested documents or arrays appropriately.
3. Create an Intermediate File: Save the transformed data into an intermediate CSV or SQL file that can be understood by Oracle.
Step 3: Set Up Oracle Database
1. Create Tables: Create the necessary tables in Oracle Database to hold the data. Make sure the columns match the data types of the transformed data.
```sql
CREATE TABLE your_table_name (
column1 datatype1,
column2 datatype2,
...
);
```
2. Prepare the Environment: Ensure that the Oracle environment is ready to receive the data. This may include setting up user permissions, tablespaces, and other necessary database configurations.
Step 4: Import Data into Oracle
1. Use SQL*Loader or External Tables: Decide whether to use SQL*Loader or Oracle External Tables for the import process.
- SQL*Loader: This utility allows you to load data from external files into tables of an Oracle database.
Create a control file that describes how the data is formatted and how it should be loaded into Oracle:
```sh
LOAD DATA
INFILE 'yourData.csv'
INTO TABLE your_table_name
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
(column1, column2, ...)
```
Run SQL*Loader using the control file:
```sh
sqlldr userid=yourOracleUsername/yourOraclePassword@yourOracleDB control=yourControlFile.ctl
```
- External Tables: This feature allows you to query data from a flat file as though it is a regular table.
```sql
CREATE TABLE your_table_name (
column1 datatype1,
column2 datatype2,
...
)
ORGANIZATION EXTERNAL (
TYPE ORACLE_LOADER
DEFAULT DIRECTORY your_directory
ACCESS PARAMETERS (
RECORDS DELIMITED BY NEWLINE
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
)
LOCATION ('yourData.csv')
);
```
After creating the external table, you can use `INSERT INTO ... SELECT FROM ...` to move the data into the actual table.
Step 5: Verify the Data Transfer
1. Check the Data: After the import process, verify that the data has been transferred correctly by running some queries on the Oracle tables.
```sql
SELECT * FROM your_table_name;
```
2. Check for Errors: Review any logs or error files generated by SQL*Loader or the External Tables process to ensure that all records have been imported successfully.
Step 6: Cleanup
1. Remove Temporary Files: After a successful import, remove any intermediate or temporary files that were created during the process.
2. Finalize the Database: Add any necessary indexes, constraints, or triggers to the Oracle tables to finalize the setup.
Notes:
- It's important to ensure that the character encoding is consistent between the exported data and the Oracle Database to avoid any issues with special characters.
- Always test the migration process with a subset of data before attempting to migrate the entire dataset.
- Back up your databases before beginning the migration process to prevent data loss in case of any issues.
- Since you are not using third-party connectors or integrations, you'll need to handle data type conversions and complex data structures manually, which can be error-prone and time-consuming. Ensure thorough testing and validation during each step.
By following these steps, you should be able to move data from MongoDB to Oracle Database without using third-party connectors or integrations. Remember that this process can be complex and may require custom scripting depending on the structure and size of your data.
Use Cases to transfer your MongoDb data to Oracle
Integrating data from MongoDb to Oracle provides several benefits. Here are a few use cases:
- Advanced Analytics: Oracle’s powerful data processing capabilities enable you to perform complex queries and data analysis on your MongoDb data, extracting insights that wouldn't be possible within MongoDb alone.
- Data Consolidation: If you're using multiple other sources along with MongoDb, syncing to Oracle allows you to centralize your data for a holistic view of your operations, and to set up a change data capture process so you never have any discrepancies in your data again.
- Historical Data Analysis: MongoDb has limits on historical data. Syncing data to Oracle allows for long-term data retention and analysis of historical trends over time.
- Data Security and Compliance: Oracle provides robust data security features. Syncing MongoDb data to Oracle ensures your data is secured and allows for advanced data governance and compliance management.
- Scalability: Oracle can handle large volumes of data without affecting performance, providing an ideal solution for growing businesses with expanding MongoDb data.
- Data Science and Machine Learning: By having MongoDb data in Oracle, you can apply machine learning models to your data for predictive analytics, customer segmentation, and more.
- Reporting and Visualization: While MongoDb provides reporting tools, data visualization tools like Tableau, PowerBI, Looker (Google Data Studio) can connect to Oracle, providing more advanced business intelligence options. If you have a MongoDb table that needs to be converted to a Oracle table, Airbyte can do that automatically.
Wrapping Up
To summarize, this tutorial has shown you how to:
- Configure a MongoDb account as an Airbyte data source connector.
- Configure Oracle as a data destination connector.
- Create an Airbyte data pipeline that will automatically be moving data directly from MongoDb to Oracle after you set a schedule
With Airbyte, creating data pipelines take minutes, and the data integration possibilities are endless. Airbyte supports the largest catalog of API tools, databases, and files, among other sources.
