Other models: hierarchical, object-oriented, NoSQL (key-value, document) basics for Tech+
Short answer
Other models: hierarchical, object-oriented, NoSQL (key-value, document) basics. 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.
Why it appears on the exam
This lesson supports FC0-U71 5.0 on CompTIA Tech+ FC0-U71. The public page gives the basic concept for free; the app adds tracking, quizzes, and weak-area practice.

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).

Concept 3
How to recognize it on Tech+
On FC0-U71, stay at beginner IT depth: identify when the question is asking about Other models: hierarchical, object-oriented, NoSQL (key-value, document) basics, then choose the basic concept or support action that matches the situation. Do not jump into advanced vendor administration unless the prompt clearly gives that scope.
