What is Oracle DB

Oracle DB is a fully scalable integrated cloud application and platform service; it is also referred to as a relational database architecture. It provides management and processing of data for both local and wide and networks. Offering software-as-a-service (SaaS), platform-as-a-service (PaaS), and infrastructure-as-a-service (IaaS), it sells a large variety of enterprise IT solutions that help companies streamline the business process, lower costs, and increase productivity.

What is DuckDB

DuckDB is an in-process SQL OLAP database management system. It has strong support for SQL. DuckDB is borrowing the SQLite shell implementation. Each database is a single file on disk. It’s analogous to “ SQLite for analytical (OLAP) workloads” (direct comparison on the SQLite vs DuckDB paper here), whereas SQLite is for OLTP ones. But it can handle vast amounts of data locally. It’s the smaller, lighter version of Apache Druid and other OLAP technologies.

Prerequisites

A Oracle DB account to transfer your customer data automatically from.
A DuckDB account.
An active Airbyte Cloud account, or you can also choose to use Airbyte Open Source locally. You can follow the instructions to set up Airbyte on your system using docker-compose.

Airbyte is an open-source data integration platform that consolidates and streamlines the process of extracting and loading data from multiple data sources to data warehouses. It offers pre-built connectors, including Oracle DB and DuckDB, for seamless data migration.

When using Airbyte to move data from Oracle DB to DuckDB, it extracts data from Oracle DB using the source connector, converts it into a format DuckDB can ingest using the provided schema, and then loads it into DuckDB via the destination connector. This allows businesses to leverage their Oracle DB data for advanced analytics and insights within DuckDB, simplifying the ETL process and saving significant time and resources.

Step 1: Set up Oracle DB as a source connector

1. Open the Airbyte platform and navigate to the "Sources" tab on the left-hand side of the screen.

2. Click on the "Oracle DB" source connector and select "Create new connection".

3. Enter a name for your connection and click "Next".

4. In the "Connection Configuration" section, enter the following information:
- Host: the hostname or IP address of your Oracle DB server
- Port: the port number used to connect to your Oracle DB server
- Database: the name of the database you want to connect to
- Username: your Oracle DB username
- Password: your Oracle DB password

5. Click "Test connection" to ensure that the connection is successful.

6. If the connection is successful, click "Next" to proceed to the "Schema Selection" section.

7. In the "Schema Selection" section, select the schema(s) you want to replicate data from.

8. Click "Create connection" to save your connection settings.

9. You can now create a new Oracle DB source in Airbyte and start replicating data from your Oracle DB database.

Step 2: Set up DuckDB as a destination connector

1. Open the Airbyte platform and navigate to the "Destinations" tab on the left-hand side of the screen.
2. Click on the "Add Destination" button located in the top right corner of the screen.
3. Scroll down the list of available destinations until you find "DuckDB" and click on it.
4. Fill in the required information for your DuckDB database, including the host, port, database name, username, and password.
5. Test the connection to ensure that the information you provided is correct and that Airbyte can successfully connect to your DuckDB database.
6. If the connection is successful, click on the "Save" button to save your DuckDB destination connector.
7. You can now use this connector to transfer data from your source connectors to your DuckDB database. Simply select the DuckDB destination connector when setting up your data integration pipelines in Airbyte.

Step 3: Set up a connection to sync your Oracle DB data to DuckDB

Once you've successfully connected Oracle DB as a data source and DuckDB as a destination in Airbyte, you can set up a data pipeline between them with the following steps:

Create a new connection: On the Airbyte dashboard, navigate to the 'Connections' tab and click the '+ New Connection' button.
Choose your source: Select Oracle DB from the dropdown list of your configured sources.
Select your destination: Choose DuckDB from the dropdown list of your configured destinations.
Configure your sync: Define the frequency of your data syncs based on your business needs. Airbyte allows both manual and automatic scheduling for your data refreshes.
Select the data to sync: Choose the specific Oracle DB objects you want to import data from towards DuckDB. You can sync all data or select specific tables and fields.
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 Oracle DB to DuckDB according to your settings.

Remember, Airbyte keeps your data in sync at the frequency you determine, ensuring your DuckDB data warehouse is always up-to-date with your Oracle DB data.

Use Cases to transfer your Oracle DB data to DuckDB

Integrating data from Oracle DB to DuckDB provides several benefits. Here are a few use cases:

Advanced Analytics: DuckDB’s powerful data processing capabilities enable you to perform complex queries and data analysis on your Oracle DB data, extracting insights that wouldn't be possible within Oracle DB alone.
Data Consolidation: If you're using multiple other sources along with Oracle DB, syncing to DuckDB 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: Oracle DB has limits on historical data. Syncing data to DuckDB allows for long-term data retention and analysis of historical trends over time.
Data Security and Compliance: DuckDB provides robust data security features. Syncing Oracle DB data to DuckDB ensures your data is secured and allows for advanced data governance and compliance management.

FAQs

What is ETL?

ETL, an acronym for Extract, Transform, Load, is a vital data integration process. It involves extracting data from diverse sources, transforming it into a usable format, and loading it into a database, data warehouse or data lake. This process enables meaningful data analysis, enhancing business intelligence.

What is Oracle DB?

What data can you extract from Oracle DB?

Oracle DB provides access to a wide range of data types, including:

• Relational data: This includes tables, views, and indexes that are used to store and organize data in a structured manner.

• Spatial data: This includes data that is related to geographic locations, such as maps, satellite imagery, and GPS coordinates.

• Time-series data: This includes data that is related to time, such as stock prices, weather data, and sensor readings.

• Multimedia data: This includes data that is related to images, videos, and audio files.

• XML data: This includes data that is stored in XML format, such as web pages, documents, and other structured data.

• JSON data: This includes data that is stored in JSON format, such as web APIs, mobile apps, and other data sources.

• Graph data: This includes data that is related to relationships between entities, such as social networks, supply chains, and other complex systems.

Overall, Oracle DB's API provides access to a wide range of data types that can be used for a variety of applications, from business intelligence and analytics to machine learning and artificial intelligence.

How do I transfer data from Oracle DB?

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:
1. Set up Oracle DB to DuckDB as a source connector (using Auth, or usually an API key)
2. Choose a destination (more than 50 available destination databases, data warehouses or lakes) to sync data too and set it up as a destination connector
3. Define which data you want to transfer from Oracle DB to DuckDB and how frequently
You can choose to self-host the pipeline using Airbyte Open Source or have it managed for you with Airbyte Cloud.

What is ELT?

ELT, standing for Extract, Load, Transform, is a modern take on the traditional ETL data integration process. In ELT, data is first extracted from various sources, loaded directly into a data warehouse, and then transformed. This approach enhances data processing speed, analytical flexibility and autonomy.

Difference between ETL and ELT?

ETL and ELT are critical data integration strategies with key differences. ETL (Extract, Transform, Load) transforms data before loading, ideal for structured data. In contrast, ELT (Extract, Load, Transform) loads data before transformation, perfect for processing large, diverse data sets in modern data warehouses. ELT is becoming the new standard as it offers a lot more flexibility and autonomy to data analysts.
