Building your pipeline or Using Airbyte

Airbyte is the only open source solution empowering data teams  to meet all their growing custom business demands in the new AI era.

Building in-house pipelines
Bespoke pipelines are:
  • Inconsistent and inaccurate data
  • Laborious and expensive
  • Brittle and inflexible
Furthermore, you will need to build and maintain Y x Z pipelines with Y sources and Z destinations to cover all your needs.
After Airbyte
Airbyte connections are:
  • Reliable and accurate
  • Extensible and scalable for all your needs
  • Deployed and governed your way
All your pipelines in minutes, however custom they are, thanks to Airbyte’s connector marketplace and AI Connector Builder.

How to Sync to Manually

Step 1: Prepare the Environment

Ensure that both IBM Db2 and MongoDB are installed and properly configured on your systems. Verify that you have administrative access to both databases and that necessary tools like `db2` command-line interface for Db2 and `mongo` shell for MongoDB are operational.

Examine the data schema within IBM Db2. Identify tables, data types, relationships, and constraints. This understanding is crucial as MongoDB is schema-less, which means you'll need to determine how to represent relational data in a document-based format.

Use the `db2 export` command to extract the data from Db2. You can export data in CSV format, which is simple and widely supported. For example:
```shell
db2 export to data.csv of del select from your_table_name
```
This command exports the table `your_table_name` into a `data.csv` file.

Convert the CSV file to JSON format, which MongoDB requires for data import. You can write a custom script in Python, JavaScript, or any language you're comfortable with to read the CSV file and output JSON. Ensure that the JSON data reflects the desired structure for MongoDB documents.

In MongoDB, decide on the database and collection where the data will reside. If the database or collection does not exist, you can create them using the MongoDB shell:
```shell
use your_database_name
db.createCollection("your_collection_name")
```

Use the `mongoimport` tool to import the JSON data into MongoDB. This tool is included with MongoDB installations. Execute the command as follows:
```shell
mongoimport --db your_database_name --collection your_collection_name --file data.json --jsonArray
```
Ensure that `data.json` is the file containing your transformed JSON data.

After importing, verify that the data in MongoDB matches the original data in IBM Db2. You can write queries in MongoDB to check the number of documents, fields, and sample data integrity. This step ensures that the migration process was successful and that the data is complete and accurate.

By following these steps, you can effectively transfer data from IBM Db2 to MongoDB without relying on third-party connectors or integrations.
