What are the best practices for data integration?

Hi Himanshu, please have a look on the below points:

1. Identify data that needs to be stored in salesforce
2. Be aware of your source data and where to store it
3. Review data management requirements
4. Decide on a schedule that fits your company
5. Leverage standard integration apps
6. Set up time for quality assurance (QA)
7. Create a salesforce data model specific to the needs of your company
8. Use salesforce functionality
9. Set up a “system of record”
10. Use help text to provide end users with context
11. Use external ids
12. Undertake regular updates and logging
13. Perform a security check

Thanks
