Q3. What is an External ID, and how is it used in data integration?

An External ID is a custom field marked as a unique identifier for records in Salesforce. It’s used during data integration to match records between Salesforce and external systems without relying on Salesforce record IDs.

Q4. How do you ensure data quality in a Salesforce system?

To ensure data quality, use validation rules, picklists, dependent picklists, and lookup fields to control data entry. Implement duplicate management features, establish data governance processes, and utilize reports and dashboards to monitor data quality metrics.

Q5. What is a Salesforce Data Management Plan?

A Salesforce Data Management Plan is a strategic document that outlines how an organization will handle its Salesforce data throughout its lifecycle. It includes data governance policies, data quality and validation rules, data deduplication strategies, data integration approaches, and data backup and retention policies.

Q6. How do you optimize data storage and performance in Salesforce?

Optimize data storage and performance by designing an efficient data model, using selective queries and filters, leveraging pagination and batch processing, utilizing Salesforce Platform Cache, following best practices for Apex and SOQL, and monitoring performance metrics.

Q7. What is the significance of Salesforce’s multi-tenant architecture for Data Architects?

Multi-tenant architecture means multiple clients share the same infrastructure, ensuring efficient use of resources and data isolation. Data Architects must consider this when designing data models and integration processes.

Q8. How do you approach designing and implementing data integration in Salesforce?

When designing and implementing data integration, consider the following steps:

• Identify the data sources, types, and formats.
• Determine the integration requirements and use cases.
• Choose the appropriate integration tools and techniques (e.g., APIs, ETL, middleware).
• Design the data mappings and transformations.
• Implement robust error handling, monitoring, and data synchronization mechanisms.
• Test and validate the integration processes.

Q9. What are the top practices for managing extensive data quantities in Salesforce?

Top practices for handling large data volumes include:

• Use selective queries with filters to minimize data retrieval.
• Leverage batch processing and pagination to manage large data sets.
• Refine data structure design to boost performance and scalability.
• Use data archival strategies to manage storage limits.

Q10. What is the role of Salesforce Platform Events?

Salesforce Platform Events enable the exchange of event-based messages between different parts of an application architecture or between Salesforce and external systems. They provide a loosely coupled, asynchronous communication mechanism that helps decouple various components, making the system more scalable and maintainable.

Q11. How do you handle data migration in Salesforce?

When handling data migration in Salesforce, consider the following steps:

• Assess the source data, including its volume, quality, and structure.
• Design the target data model in Salesforce and map source data to the target structure.
• Choose the appropriate migration tools (e.g., Data Loader, Data Import Wizard, third-party tools).
• Clean and transform the data as needed, ensuring data quality and deduplication.
• Assess the data migration process and authenticate the transferred data.

Q12. In Salesforce, how do you safeguard data security and compliance?

To ensure data security and compliance in Salesforce, consider the following best practices:

• Employ field-level security to limit access to confidential fields.
• To defend sensitive information, utilize encryption functionalities, such as Salesforce Shield Platform Encryption.
• Establish data retention and deletion policies in compliance with data protection regulations (e.g., GDPR, CCPA).
• Regularly review and audit user access and activities to identify potential security risks.

Q13. What is the difference between a Salesforce Data Architect and a Salesforce Solution Architect?

Q14. What is the purpose of Salesforce Big Objects, and how do they differ from Custom Objects?

Salesforce Big Objects are designed to store and manage massive amounts of data (billions of records) with high performance and low latency. They are different from Custom Objects in several ways:

• Big Objects use a specialized data storage architecture optimized for handling large data volumes.
• They have limited functionality compared to Custom Objects (e.g., no triggers, validation rules, or field history tracking).
• Big Objects support a subset of SOQL for querying data and require asynchronous data manipulation using Bulk API.

Q15. How do you handle data deduplication during data migration or integration?

To handle data deduplication during data migration or integration:

• Configure Salesforce duplicate rules and matching rules to prevent duplicate record creation.
• Use Data Loader, Data Import Wizard, or third-party tools with deduplication features to clean and merge duplicate data during the import process.
• Implement data governance processes, including assigning data stewards responsible for monitoring and resolving duplicate records.
• Instruct end-users on data input best practices to reduce the generation of duplicate entries.
• Regularly run reports and use deduplication tools to identify and merge duplicate records in the system.
