It's C, because D doesn't address the data cleansing issue. How to set up a Staging Database? Simply create a Sandbox. Create a Salesforce Sandbox: Sandboxes are copies of your Salesforce organization that you can use for various purposes, including development, testing, and staging. Create a sandbox specifically designated as your staging environment. Salesforce provides different types of sandboxes, such as Developer, Developer Pro, Partial Copy, Full Copy, and more, each with varying features and data capabilities. Define Custom Objects and Fields: In your staging environment, create custom objects and fields that correspond to the data you want to migrate. Define the necessary fields, data types, and relationships based on your data requirements. Extract Data from Legacy Systems: Extract data from your legacy systems or source databases that you intend to migrate. This may involve using data extraction tools, APIs, or ETL processes to retrieve data from various sources. Transform and Cleanse Data: Perform data transformation and cleansing processes to ensure data quality and consistency. This may include removing duplicates, standardizing formats, validating data against predefined rules, and resolving any inconsistencies or errors. You can use Salesforce's data manipulation tools, such as Data Loader, to perform these tasks. Load Data into Custom Objects: Once the data is cleaned and transformed, load it into the respective custom objects in your Salesforce staging environment. You can use Salesforce's data loading tools, such as Data Import Wizard or Data Loader, to import data from various file formats or databases. Validate and Verify Data: Perform data validation checks to ensure that the loaded data accurately represents the source data. Verify that the data in your staging environment aligns with the expected structure and content. Prepare for Migration: Once the data is successfully loaded and validated in your staging environment, you can proceed with migrating the data to the production environment in Salesforce. Follow the appropriate migration procedures, such as using Salesforce's deployment tools or data integration tools, to move the data from the staging environment to the production environment.
