Implementing data integration involves several steps: 1. Identify Data Sources: List all the data sources such as CRM systems, social media platforms, and sales data. 2. Choose the Right Tools: There are various tools available for data integration, including ETL (Extract, Transform, Load) tools and data warehouses. 3. Data Mapping: Define how data from different sources will be combined and standardized. 4. Data Cleansing: Ensure that the data is clean and free from errors before integration. 5. Integration Process: Use the chosen tools to combine the data into a unified system. 6. Continuous Monitoring: Regularly check the integrated data for accuracy and consistency.
