Lattice Guide

Problem Statement

As databases contain more information, poorly organized structures can create difficulties with data duplication, inconsistent records, and complicated relationships between tables.

Learners may understand how to retrieve information but still find it challenging to design a database that stores related data logically. Deciding which attributes belong together, how tables should connect, and when information should be separated requires a deeper understanding of relational design principles.

Without a structured approach to database planning, changes to one section of a dataset may introduce inconsistencies elsewhere.

Solution

Lattice Guide provides a detailed introduction to relational database modeling and organization.

The course explains how to examine information requirements, identify entities and attributes, define relationships, and develop logical table structures.

Learners explore normalization principles, database constraints, and schema documentation through practical examples. Guided activities demonstrate how different design choices affect data organization and consistency.

What's Inside

• Introduction to relational database design
• Identifying entities, attributes, and relationships
• Conceptual and logical data modeling
• Entity-relationship diagrams
• Primary, foreign, and composite keys
• Introduction to database normalization
• First, second, and third normal forms
• Understanding functional dependencies
• Reducing unnecessary data duplication
• Database constraints and data integrity
• Schema planning and documentation
• Practical database modeling exercises
• Design review questions and sample scenarios
• Certificate of completion

Who Is This For?

Lattice Guide is intended for learners who already understand relational databases and basic queries and want to study database design in greater detail.

It is suitable for independent learners, students exploring data modeling, and individuals interested in organizing structured information across multiple related tables.

Prior familiarity with primary keys, foreign keys, table relationships, and introductory queries is recommended.

What You'll Learn

• Identify entities and attributes from information requirements.
• Create introductory entity-relationship diagrams.
• Define logical relationships between database tables.
• Select primary and foreign keys for relational structures.
• Explain the purpose of database normalization.
• Distinguish between the first three normal forms.
• Recognize functional dependencies between attributes.
• Identify unnecessary duplication within table structures.
• Apply introductory integrity constraints.
• Develop and document a relational database schema.
• Evaluate database structures through practical design exercises.
