Advanced Database Tables and Queries with GUI Training
Description
This course equips learners with the skills to design complex database tables and queries using a graphical user interface (GUI) based database system. Participants will learn to solve real-world problems by applying advanced database design principles, including normalization, relationships, and query optimization. The course bridges theoretical database concepts with practical GUI tools, enabling efficient data management and reporting.
Learning Outcomes
- Design normalized database tables with appropriate relationships using a GUI-based database management system.
- Implement complex queries involving multiple tables, aggregate functions, and subqueries to extract meaningful information.
- Evaluate database designs for efficiency, integrity, and scalability to meet given problem requirements.
- Apply data validation rules and referential integrity constraints to ensure data accuracy and consistency.
- Analyze business problems and translate them into database solutions using advanced table and query design.
- Demonstrate the ability to optimize queries for performance and troubleshoot common database errors.
Target Audience
This course is ideal for database administrators, data analysts, and IT professionals who need to design and manage complex databases using GUI tools. It is also suitable for individuals seeking to advance their skills in database design and querying for business intelligence or operational systems.
Prerequisites
None — open enrollment.
Course Outline
Objectives:
• Design complex database tables with proper normalization and indexing.
• Write advanced SQL queries using JOINs, subqueries, and aggregate functions.
• Implement data integrity constraints and relationships.
• Understand the use of views and stored procedures.
Topics:
• Review of relational database concepts and normalization.
• Creating tables with primary keys, foreign keys, and indexes.
• Advanced SELECT queries: multi-table JOINs, subqueries, and UNION.
• Aggregate functions and GROUP BY with HAVING clauses.
• Data integrity: CHECK constraints, default values, and cascading actions.
• Introduction to views and stored procedures.
• Hands-on exercise: Design and populate a sample database.
Objectives:
• Design and build a graphical user interface (GUI) for database interaction.
• Connect a GUI application to a database using appropriate drivers.
• Implement data entry, retrieval, update, and deletion via the GUI.
• Apply basic error handling and input validation.
Topics:
• Overview of GUI development tools (e.g., Visual Studio, Lazarus, or web-based).
• Designing forms: data entry fields, buttons, grids, and navigation.
• Database connectivity: connection strings, ODBC/JDBC, or ADO.NET.
• Executing SQL queries from the GUI: SELECT, INSERT, UPDATE, DELETE.
• Displaying query results in data grids or list views.
• Error handling and validation techniques.
• Practical: Build a complete GUI application to manage a database.
Practicals
Overview
Hands-on practicals are essential for learners to apply database design and query skills in a real-world context and to build a functional GUI application. Learners will work on structured exercises and a culminating project that integrates all concepts.
Practical Activities
- Database Design and Advanced Queries — Learners create a normalized database with multiple tables, define relationships and constraints, then write advanced SQL queries including JOINs, subqueries, and aggregation. (3h)
- GUI Application Development — Learners build a simple GUI application that connects to their database, allows data entry, displays records, and supports update and delete operations. (3h)
Summatives
Each delegate is assessed continuously throughout the course via daily exercises, scored practical assignments, and a final summative test at the end.
Practical Assignments — 30%
Practical assignments are observed and scored against a rubric during the practical sessions. Each delegate's practical mark is averaged into a single 100% score and contributes 30% to the final total.
Daily Exercises — 20%
Every training day ends with a multiple-choice exercise scored out of 100%. The scores from each daily exercise are averaged across the duration of the course to produce a Daily Average mark, which contributes 20% to the final total.
Final Test — 50%
On the last day a final summative test is written. It is a multiple-choice paper with multiple-answer questions: each question may have more than one correct option, and a single wrong selection on a question marks the entire question wrong — no partial credit. The final test is scored out of 100% and contributes 50% to the overall mark.
Final Total
| Component | Out of | Weight |
|---|---|---|
| Practical Assignments (rubric-scored) | 100% | 30% |
| Daily Average (multiple choice) | 100% | 20% |
| Final Test (multi-answer multiple choice) | 100% | 50% |
| Final Total | — | 100% |
All marks are recorded on the AATICD LMS and visible to each learner under their account.
Certificate
How it works
- Certificates are auto-generated on the AATICD LMS as soon as the marks pass the 50% threshold.
- Each certificate is a branded PDF with the delegate's name, the course title, the unit standard ID, NQF level, credits, and the date of issue.
- You can download or print your certificate from your LMS dashboard at any time after issue — there's no reissue fee and no expiry date.
- If you scored under 50% you can sit the final test again at the next scheduled session at no extra cost.
Where to find it
Sign in to the LMS, open your dashboard, and your certificates appear under My Certificates. Each entry has a View / Download button and a print option.
