• Batch Processing: This involves extracting data from source systems at scheduled intervals, transforming it, and loading it into a target system. This is a common approach for data warehousing and business intelligence.
• Real-Time Data Integration: This involves integrating data in real-time as it is generated. This is a more complex approach, but it provides the most up-to-date view of the data. Common techniques include Change Data Capture (CDC) and message queuing.
• Data Virtualization: This approach allows users to access data from different sources without physically moving the data. Data virtualization creates a virtual layer that integrates data from different sources, allowing users to query the data as if it were in a single database.
• Extract, Transform, Load (ETL): ETL is a traditional data integration process that involves extracting data from source systems, transforming it, and loading it into a data warehouse or other target system. ETL tools are used to automate this process.
• Extract, Load, Transform (ELT): ELT is a more modern approach to data integration that involves extracting data from source systems, loading it into a data lake or cloud-based data warehouse, and then transforming it. This approach leverages the processing power of the data lake or cloud-based data warehouse to perform the transformations.
• Enterprise Service Bus (ESB): An ESB is a software architecture pattern used for integrating applications and services. It acts as a central communication hub, allowing different applications to exchange data and messages.
• API Integration: This involves using APIs (Application Programming Interfaces) to connect different applications and exchange data. APIs are a common way to integrate cloud-based applications and services.
