Through practical scenarios and architecture-focused discussions, learners develop the ability to evaluate requirements, select appropriate solutions and create robust enterprise data architectures aligned with business and technical objectives.
INTERMEDIATE LEVEL
1. What is Salesforce Data Architecture?
Answer:
Salesforce Data Architecture defines how data is structured, stored, related, accessed and integrated across Salesforce and external systems. It includes data modeling, object relationships, security, data migration, integration, governance and performance considerations.
2. What is the difference between standard and custom objects?
Answer:
Standard objects are provided by Salesforce, such as Account, Contact, Opportunity and Case. Custom objects are created to meet organization-specific business requirements. Both can support fields, relationships, validation rules, security and automation.
3. What are the main Salesforce relationship types?
Answer:
Common relationships include Lookup, Master-Detail, Many-to-Many using junction objects and Hierarchical relationships for specific use cases. The appropriate relationship depends on ownership, sharing requirements, reporting needs and business logic.
4. When would you use a Master-Detail relationship instead of Lookup?
Answer:
Master-Detail is appropriate when the child record depends strongly on the parent. It supports inherited security, ownership and sharing behavior and enables roll-up summary fields. Lookup is better when records need greater independence.
5. What is a junction object?
Answer:
A junction object enables a many-to-many relationship between two objects. It normally contains two Master-Detail relationships, one to each participating object. For example, a Student Course Enrollment object can connect Students and Courses.
6. What is data normalization in Salesforce?
Answer:
Data normalization organizes data to minimize duplication and improve consistency. In Salesforce, architects consider normalization when designing objects and relationships while balancing performance, reporting requirements, usability and platform limitations.
7. What is Salesforce Data Loader?
Answer:
Data Loader is a client application used to insert, update, upsert, delete, export and hard-delete Salesforce records. It is particularly useful for handling large data volumes and performing bulk data operations.
8. What is an external ID?
Answer:
An External ID is a custom field used to store an identifier from an external system. It is especially useful for integration and data migration because it enables efficient record matching and upsert operations.
9. What is an upsert operation?
Answer:
Upsert combines insert and update functionality. Salesforce checks whether a record already exists using an ID or External ID. If a matching record exists, it is updated; otherwise, a new record is created.
10. What is a Salesforce data model?
Answer:
A Salesforce data model represents objects, fields and relationships that define how business information is organized. A good data model supports business processes while considering scalability, security, reporting, integration and data quality.
11. What factors should be considered when designing a Salesforce data model?
Answer:
Architects should consider business requirements, object relationships, data volume, ownership, sharing, reporting, integration, data lifecycle, security, scalability and platform limits. The model should avoid unnecessary complexity and duplication.
12. What is data governance?
Answer:
Data governance establishes policies, responsibilities and processes for maintaining data quality, security, consistency, availability and compliance. In Salesforce, governance can cover ownership, validation, access control, retention and data stewardship.
13. How do you maintain data quality in Salesforce?
Answer:
Data quality can be improved through validation rules, duplicate management, standardized values, required fields, automation, integration controls, data cleansing and regular monitoring. Governance policies should also define ownership and maintenance responsibilities.
14. What is the difference between Salesforce ID types?
Answer:
Salesforce commonly uses 15-character case-sensitive IDs and 18-character case-insensitive IDs. The 18-character version is generally preferred for integrations and external systems because it avoids case-sensitivity issues.
15. Why is data volume important in Salesforce architecture?
Answer:
Large data volumes can affect query performance, reporting, sharing calculations and data operations. Architects must consider selective queries, indexing, archival, data lifecycle management, asynchronous processing and appropriate integration strategies.
ADVANCED LEVEL
1. How would you design a Salesforce architecture for a high-volume enterprise?
Answer:
I would begin by analyzing data volume, transaction patterns, access requirements and integration dependencies. I would design an optimized data model, use selective queries and appropriate indexing, establish archival strategies and choose synchronous or asynchronous integrations based on business requirements. I would also evaluate sharing complexity, reporting architecture and platform limits to ensure long-term scalability.
2. How do you approach Large Data Volume (LDV) architecture in Salesforce?
Answer:
LDV architecture requires careful consideration of indexing, query selectivity, data ownership, sharing calculations and data lifecycle. I would minimize unnecessary records, archive historical data, optimize reports and SOQL queries and use asynchronous processing where appropriate. I would also review data access patterns before finalizing the object and sharing architecture.
3. How would you decide whether data should reside in Salesforce or an external system?
Answer:
I would evaluate the business purpose, transaction requirements, security, regulatory requirements, data volume, latency, ownership and Salesforce licensing. Data that requires Salesforce-native processing may belong in Salesforce, while very large analytical or system-of-record datasets may remain externally and be accessed through appropriate integration patterns.
4. How would you design a Salesforce data integration strategy?
Answer:
I would identify system-of-record ownership, data synchronization requirements, volume, frequency and latency. Then I would select suitable integration patterns such as request-response, fire-and-forget, batch synchronization or event-driven integration. I would also define error handling, retry mechanisms, monitoring, security and reconciliation processes.
5. What is the difference between synchronous and asynchronous integration?
Answer:
Synchronous integration requires the requesting system to wait for an immediate response. It is suitable when the response is required to continue the transaction. Asynchronous integration processes data independently and is useful for high-volume operations, long-running processes and scenarios where immediate responses are unnecessary.
6. How would you handle duplicate customer records across multiple systems?
Answer:
I would establish a master data strategy and define a unique customer identifier. Salesforce matching and duplicate rules can help identify duplicates, while integration logic can use External IDs for reliable record matching. I would also establish data stewardship and cleansing processes to prevent duplicates from being recreated.
7. How do you design Salesforce data security at the architecture level?
Answer:
I would use a layered approach involving object permissions, field-level security, record-level sharing, role hierarchy, permission sets and appropriate sharing mechanisms. I would apply least-privilege principles and ensure sensitive data is accessible only to authorized users and systems.
8. How would you optimize Salesforce performance for millions of records?
Answer:
I would review data access patterns, indexes, query selectivity, sharing architecture and reporting requirements. I would consider archiving or purging unnecessary records, optimizing automation and using asynchronous processing. External analytics or data platforms may also be appropriate for large-scale historical analysis.
9. What is data skew and why is it important?
Answer:
Data skew occurs when records are distributed unevenly, creating performance and locking challenges. Examples include ownership skew and account data skew. An architect should identify potential skew during design and distribute ownership or relationships appropriately to reduce contention and improve scalability.
10. How would you design a data migration strategy for Salesforce?
Answer:
I would first profile and cleanse the source data, map source fields to Salesforce objects and establish transformation rules. Then I would define dependencies and migration sequencing, load reference data first and transactional data afterward. I would perform test migrations, validate record counts and relationships and maintain reconciliation procedures before production deployment.
11. How do you determine the correct migration sequence?
Answer:
The sequence depends on object dependencies and relationships. Generally, foundational or parent records are loaded before dependent child records. Reference data is typically established first, followed by accounts, contacts and transactional or relationship-dependent records. External IDs and relationship mapping help maintain referential integrity.
12. How would you architect data retention and archival?
Answer:
I would classify data according to business, regulatory and operational requirements. Frequently accessed data can remain in Salesforce while older data may be archived to an appropriate external platform. The strategy should define retention periods, retrieval requirements, security, ownership, compliance and automated lifecycle processes.
13. How would you handle conflicting data between Salesforce and an external system?
Answer:
I would establish a clear system-of-record strategy and define ownership for each data domain. Integration rules should determine which system has authority and how conflicts are resolved. I would also implement timestamps, unique identifiers, validation and reconciliation processes to detect and resolve inconsistencies.
14. How do you balance normalization and denormalization in Salesforce?
Answer:
Normalization reduces duplication and improves consistency, while denormalization can improve performance and simplify reporting or application access. I would choose the appropriate approach based on transaction volume, reporting requirements, automation, query performance and maintainability rather than applying one model universally.
15. A company has millions of Salesforce records and slow reports. How would you investigate the issue?
Answer:
I would first identify which reports and datasets are affected and analyze filters, joins, sharing calculations and data volumes. I would review indexing and filter selectivity, evaluate object relationships and assess whether historical data should be archived. I would then optimize report design and the underlying data architecture while validating performance against realistic production-scale volumes.
