SQLite Learning Path: From Zero to Hero (for C# Senior Engineers)

Phase 1: Fundamentals of SQLite

1. Introduction to SQLite

• What is SQLite?
• Use cases (embedded apps, local storage, prototyping)
• SQLite vs. SQL Server/MySQL/PostgreSQL

Resources:

• Official SQLite Documentation
• SQLite Tutorial

2. Installing SQLite

• Install SQLite CLI (sqlite3)
• Use DB Browser for SQLite (GUI)
• Create a .sqlite or .db file

Practice:

• Create a sample database using CLI or DB Browser

---

Phase 2: SQL Basics in SQLite

3. Data Definition Language (DDL)

• CREATE TABLE, ALTER TABLE, DROP TABLE
• SQLite’s dynamic typing system

4. Data Manipulation Language (DML)

• INSERT, UPDATE, DELETE, SELECT
• WHERE, ORDER BY, LIMIT, LIKE, IN

5. Constraints

• PRIMARY KEY, UNIQUE, NOT NULL, DEFAULT, CHECK, FOREIGN KEY

6. Indexes and Views

• CREATE INDEX and performance considerations
• CREATE VIEW for abstraction

7. SQLite Functions

• Date/Time functions
• String and aggregate functions

Practice:

• Build a database for a Notes or To-Do List app

---

Phase 3: Intermediate Features & Integration with C#

8. Advanced Queries

• JOINs (INNER, LEFT, etc.)
• Subqueries and CTEs (WITH)
• Window functions (optional)

9. SQLite with C# (ADO.NET)

• Use System.Data.SQLite or Microsoft.Data.Sqlite
• Perform CRUD operations
• Use parameterized queries
• Handle transactions

Practice:

• Build a Console or WPF app using SQLite

---

Phase 4: Tools, Performance, and Best Practices

10. Performance Optimization

• Indexing strategies
• VACUUM, ANALYZE
• Use EXPLAIN QUERY PLAN

11. File Handling and Size

• Understanding .db file structure
• In-memory databases (:memory:)
• SQLite encryption (see SQLCipher)

12. Best Practices

• Schema versioning (consider migrations)
• Error handling in C#
• Caching and optimization

---

Phase 5: Expert Usage & Real-World Projects

13. Advanced Use Cases

• Triggers
• Custom SQLite functions in C#
• Using ORMs (Dapper, EF Core with SQLite)

14. Projects

• Offline-first desktop app
• Mobile app (MAUI/Xamarin) with SQLite
• Microservice prototype using SQLite
