Comprehensive Module-by-Module Breakdown
Every session blends live engineering theory with 60% hands-on laboratory problem solving.
Query tuning begins with execution plan literacy. In this module, you will learn to read and analyze DBeaver's graphical and tabular Explain Plan representations across PostgreSQL and MySQL.
- Deconstructing Plan Nodes: Understand Sequential Scans vs Index Scans vs Index Only Scans, Bitmap Heap Scans, and Hash Joins.
- Interpreting Costs and Row Estimates: Understand startup cost, total cost, actual loops, and rows filtered by conditions.
- Diagnosing Cardinality Errors: Identifying stale database statistics (`ANALYZE`) that lead the query planner astray.
- DBeaver Execution Plan Comparison: Comparing before-and-after query plans side-by-side inside DBeaver to prove optimization ROI.
Learn how to construct surgical indexes and refactor poorly structured queries directly within DBeaver's SQL Editor.
- Index Architectures: B-Tree, Composite Multi-Column Indexes (ordering columns for left-prefix matching), Partial Indexes, and Expression Indexes.
- Subquery Optimization: Transforming correlated subqueries into efficient JOINs and Common Table Expressions (CTEs).
- Window Functions & Partitioning: Writing high-performance analytics using `ROW_NUMBER()`, `RANK()`, `LEAD()`, and `LAG()` without full table scans.
- Index Bloat & Fragmentation: Auditing index size and rebuilding fragmented indexes via DBeaver maintenance wizards.
Turn hundreds of disconnected tables into an intuitive, visually documented architectural blueprint.
- Entity Relationship Generation: Automatically generating complete schema diagrams from live production databases.
- Virtual Entity Relations: Defining virtual primary keys and foreign keys for legacy databases lacking explicit relational constraints.
- Color Coding & Logical Grouping: Organising complex schemas by business domain (Billing, Auth, Orders, Inventory).
- Export & Documentation: Exporting high-resolution vector diagrams (SVG, GraphML, PNG) for stakeholder documentation.
Equip yourself with practical DBA operational controls to protect database stability and diagnose live operational incidents.
- Session Manager: Inspecting active client connections, idle-in-transaction states, and resource utilization.
- Lock Inspection: Uncovering exclusive table locks and gracefully terminating blocking queries (`pg_terminate_backend` / `KILL`).
- Maintenance Tasks: Scheduling VACUUM, ANALYZE, OPTIMIZE TABLE, and CHECK operations through DBeaver’s administrative console.
- User & Privilege Auditing: Granting and revoking granular DDL/DML permissions to enforce least-privilege policies.
Migrating millions of rows across different database engines without third-party proprietary tools.
- Cross-Database Transfer Wizard: Moving tables seamlessly between MySQL, PostgreSQL, Oracle, and SQL Server.
- Column Mapping & Data Type Casting: Resolving type incompatibilities (e.g. `VARCHAR` vs `TEXT`, `DATETIME` vs `TIMESTAMPTZ`, `BLOB` vs `BYTEA`).
- Batch Sizes & Performance Tuning: Tuning fetch sizes and transaction commit intervals for multi-gigabyte transfers.
- Schema Diff & Comparison: Comparing two database structures and generating ALTER scripts to sync environments.
Hardening your client environment against catastrophic mistakes and unauthorized access.
- Multi-Hop SSH Tunneling & ProxyJump: Accessing private VPC database clusters securely.
- Production Connection Safeguards: Enabling read-only session modes, connection color-coding, and commit confirmation dialogs.
- Secrets & Credential Security: Storing passwords in operating system keystores and master password encryption.
- Final Capstone Project: Complete an end-to-end performance diagnosis, schema refactor, and live migration on a simulated production environment.
Your Dedicated Cloud Laboratory
Every student receives individualized cloud database instances pre-loaded with realistic production workloads.
