- Overview

Big data integration combines fragmented data from multiple sources, such as databases, applications, and cloud platforms, into a single, unified dataset. 

Its primary purpose is to provide a complete and accurate organizational view for improved decision-making, advanced analytics, and comprehensive reporting. 

This is typically achieved through ETL (Extract, Transform, Load) processes, where data is extracted, converted into a standardized format, and then loaded into a central repository like a data warehouse or data lake. 

1. What it is: 

  • Consolidation: It's the process of gathering and merging data from disparate systems and formats into a single, coherent dataset.
  • Unified View: The goal is to break down data silos, providing a comprehensive, consistent, and up-to-date picture of an organization's data assets.

2. Purpose:

  • Informed Decision-Making: A consolidated view enables data-driven decisions by making insights more accessible and actionable across the enterprise.
  • Advanced Analytics: It creates a foundation for deeper analysis and machine learning, allowing organizations to uncover trends and patterns previously hidden in siloed data.
  • Improved Reporting: Unified data facilitates more accurate and complete reporting, providing a holistic perspective on business performance.

3. How it works:

  • ETL Process: A common method involves Extracting data from various sources, Transforming it to ensure consistency and quality, and Loading it into a central target system like a data warehouse or data lake.
  • ELT (Extract, Load, Transform): Another approach where data is loaded first and then transformed in the target system.
  • Data Virtualization: A technique that provides a unified view of data from disparate sources without physically copying it, offering real-time access and agility.
  • Data Lakes and Data Warehouses: Centralized repositories where integrated data is stored for analysis and reporting.
