MongoDB Training Helped SQL Specialists in Finance Handle New Tech Demands

Executive Summary

A Singapore-based firm in the financial services sector needed its database administration team to transition from traditional SQL to MongoDB.With critical NoSQL-based projects on the horizon, the team needed to learn how to deploy and manage MongoDB quickly and effectively. To address this, a focused, 2-day onsite training was delivered in a 1:1 format. Seven experienced DBAs participated. The training was tailored to their SQL background and included hands-on labs, real-world financial use cases, and side-by-side comparisons of SQL vs MongoDB practices. By the end of the program, all participants had independently deployed MongoDB databases and were equipped to handle upcoming NoSQL workloads across the Asia region.

‍

Why This Training Was Needed

The client’s team was transitioning from SQL-based databases to NoSQL solutions. They required MongoDB administration training to:

• Understand the fundamentals of NoSQL databases.
• Gain hands-on experience in deploying and managing MongoDB.
• Adapt their existing SQL skills to the new database system.

‍

Key Challenges

• Knowledge Gap: The team lacked foundational NoSQL knowledge.
• SQL Mindset: Shifting from structured tables to schema-less documents was difficult.
• Querying Differences: MongoDB’s aggregation framework differed from SQL joins.
• Scaling Approach: Transitioning from vertical to horizontal scaling required a new strategy.
• Project Deadlines: Upskilling was time-sensitive due to upcoming deployments.

‍

Training Development

The training was based on NobleProg’s MongoDB Admin program (Course Link), but was carefully customized to align with the team’s SQL expertise, industry-specific needs, and hands-on learning objectives.

• Bridging SQL to MongoDB: The training used direct comparisons to help participants seamlessly transition from relational databases to NoSQL. Topics included:
  • Tables vs. Collections, Rows vs. Documents – Understanding MongoDB’s document model.
  • SQL Joins vs. Embedded Documents & References – Optimizing data relationships.
  • ACID Transactions vs. MongoDB’s Multi-Document Transactions – Ensuring data integrity in banking applications.

‍

• Industry-Specific Use Cases: Since the team worked in financial services, the curriculum incorporated real-world banking scenarios, such as:
  • Managing customer data efficiently with MongoDB’s flexible schema.
  • Implementing transaction consistency using multi-document transactions for banking workflows.
  • Scaling strategies for high-volume financial data processing.

‍

• Hands-On Deployment Labs: The training emphasized practical learning, enabling participants to:
  • Install, configure, and deploy MongoDB on-premises.
  • Set up replica sets and sharding for high availability and scalability.
  • Optimize performance using indexing and query tuning techniques.
  • Debug and troubleshoot real-world MongoDB issues.

By the end of the training, participants had built confidence in MongoDB administration, successfully deployed working databases, and were ready to support upcoming NoSQL projects within the organization.
