Advanced SQL Architecture and Optimization Workshop

Advanced SQL Architecture and Optimization Workshop

From design to migration in a single day

In the modern data landscape, database professionals must bridge the gap between design elegance and runtime performance. Poor table design or unchecked normalization can degrade even the best business logic. This intensive one-day course focuses on translating customer requirements into efficient table structures, applying normalization intelligently, identifying and resolving performance bottlenecks, and executing seamless migrations. Delivered by an instructor with over 30 years of industry experience, the training emphasizes real-world, production-proven practices instead of academic formalities.

Learning Outcomes

Participants will learn to:

• Translate business requirements into sound relational table designs.
• Apply normalization principles effectively and recognize practical exceptions.
• Detect performance bottlenecks using SQL tracing and execution diagnostics.
• Resolve issues through structural and query-level optimizations.
• Plan and perform reliable data and schema migrations.

Prerequisites

• Working knowledge of SQL and relational database concepts.
• Familiarity with primary and foreign keys, indexes, and joins.
• Basic experience using SQL Server, PostgreSQL, MySQL, or similar platforms.

Training Outline

Table Design According to Customer Requirements

• Requirement analysis and data modeling fundamentals
  • Identifying entities and relationships
  • Mapping business processes to data structures
• Logical and physical design considerations
  • Column naming conventions and datatype selection
  • Nullability, constraints, and referential integrity
• Relationship modeling
  • One-to-one, one-to-many, and many-to-many structures
  • Handling optional and mandatory relationships
• Scalability and maintainability factors
  • Anticipating schema evolution
  • Versioning and documentation of table structures

Normalization of Tables

• Principles of normalization
  • Purpose and goals of normalization
  • Normal forms (1NF, 2NF, 3NF, BCNF)
• Advantages and trade-offs
  • Redundancy reduction vs. query performance
  • Controlled denormalization for performance tuning
• Structural assessment
  • Detecting normalization violations
  • Planning schema adjustments for balance

Identification of Performance Bottlenecks

• Query performance fundamentals

  • Schema refinement and partitioning
  • Index restructuring and statistics maintenance
• Validation and verification
  • Performance benchmarking
  • Regression and impact testing

Migration

• Migration strategy and planning
  • Scope definition and dependency mapping
  • Downtime minimization and rollback planning
• Data preparation and transformation
  • Data quality assessment and cleansing
  • Schema version control and migration sequencing
• Execution and verification
  • Bulk transfer vs. incremental migration
  • Post-migration validation and performance monitoring
