Basic normalization concept (reducing redundancy) for Tech+
Short answer
Basic normalization concept (reducing redundancy). There are multiple ways to structure a database: - Flat File: Data in plain text or single table (CSV, Excel). All data in one place. Drawbacks: redundant data, inconsistent, doesn't handle complex queries well. Works for small, simple datasets. - Relational Database: Multiple tables with relationships via foreign keys. Reduces redundancy through normalization. Ensures consistency and allows complex queries (joins). - Normalization: Design process eliminating redundant data. Store customer info once in Customers table; Orders table references by ID.

Drawbacks: redundant data, inconsistent, doesn't handle complex queries well. Works for small, simple datasets. - Relational Database: Multiple tables with relationships via foreign keys. Reduces redundancy through normalization. Ensures consistency and allows complex queries (joins). - Normalization: Design process eliminating redundant data. Store customer info once in Customers table; Orders table references by ID. More tables, but less repetition. - Other models: - Hierarchical: Tree structure (parent-child). Good for one-to-many but inflexible for many-to-many.
