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:

  • 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.

Start syncing with Airbyte in 3 easy steps within 10 minutes

Set up a Oracle DB connector in Airbyte

Connect to Oracle DB or one of 400+ pre-built or 10,000+ custom connectors through simple account authentication.

Set up AWS Datalake for your extracted Oracle DB data

Select AWS Datalake where you want to import data from your Oracle DB source to. You can also choose other cloud data warehouses, databases, data lakes, vector databases, or any other supported Airbyte destinations.

Configure the Oracle DB to AWS Datalake in Airbyte

This includes selecting the data you want to extract - streams and columns -, the sync frequency, where in the destination you want that data to be loaded.

How to Sync Oracle DB to AWS Datalake Manually

Begin by ensuring your Oracle database is ready for data extraction. Identify the tables and data you wish to move. Ensure you have the necessary permissions to access and extract data from the Oracle database. Verify that the data types and formats in the database are compatible with AWS services.

Use Oracle SQLPlus, a command-line utility, to connect to your Oracle database and extract the data. You can write SQL queries to export data into a flat file format, such as CSV. For example, you can use the `SPOOL` command in SQLPlus to write query results to a local file.

Save the extracted data files (e.g., CSV files) to a secure location on your local machine or on-premises server. Ensure that the data files are organized and named clearly for easy identification and access.

Install the AWS Command Line Interface (CLI) on your local machine. Configure the AWS CLI with the necessary credentials (Access Key ID and Secret Access Key) and default region settings using the `aws configure` command. Ensure your IAM user has the necessary permissions to access and upload data to Amazon S3.

Use the AWS CLI to upload the extracted data files from your local storage to an Amazon S3 bucket. Create a new S3 bucket if necessary and organize the data files within the bucket using a logical folder structure. Use the `aws s3 cp` or `aws s3 sync` command to perform the upload.

Set up AWS Glue to catalog your data stored in Amazon S3. Create a new AWS Glue Crawler, which will automatically scan the data in your S3 bucket and populate the AWS Glue Data Catalog with metadata definitions. This step is crucial for making your data easily queryable and analyzable.

Use Amazon Athena to query the data directly from the S3 bucket. Athena allows you to run SQL queries on your data in S3 and is fully integrated with the AWS Glue Data Catalog. You can easily analyze your data and perform various operations without moving the data to another database or service.
By following these steps, you can successfully move data from an Oracle database to an AWS Data Lake without relying on third-party connectors or integrations.

FAQs

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.

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.

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.

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 AWS Datalake 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 AWS Datalake and how frequently
You can choose to self-host the pipeline using Airbyte Open Source or have it managed for you with Airbyte Cloud. 

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.

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.
