DATA LEARNING PATH

Database Development Roadmap

Learn relational design, compare the SQL and document database courses, then choose an integration course matching a language you already study.

Who this path is for

Learners who want database design knowledge or application persistence skills.

Before you begin

The database introductions can be studied independently. Language integration courses require familiarity with their named language.

Learning outcomes

  • Study relationships and normalization
  • Choose a relational or document database course
  • Find matching language-specific integration material

STEP BY STEP

Your learning sequence

Core stages are ordered. Branches are labeled as recommendations, choices, or optional follow-ons.

  1. Core sequence

    Relational design foundation

    The design guide begins with database/table design, keys, relationships, and normalization forms.

  2. Choose one path

    Choose a database course

    MySQL, PostgreSQL, SQL Server, and SQLite outlines cover structures, operations, queries, and joins; MongoDB covers document database structure and operations. Select a system, not every system as a sequence.

    • MySQLCourseCourse page is public; selected sections require login.
    • PostgreSQLCourseCourse page is public; selected sections require login.
    • SQL ServerCourseCourse page is public; selected sections require login.
    • SQLiteCourseCourse page is public; selected sections require login.
    • MongoDBCourseCourse page is public; selected sections require login.

    Supplementary practice and tools

  3. Optional branch

    Connect a database from an application

    Choose integration material matching your language: SQLite with C, Java/JDBC, PHP/PDO or MySQLi, Python SQLite/PostgreSQL/SQLAlchemy, or .NET data access.

  4. Optional branch

    Practice and extend

    Use the course pages for their available assessments and gated practice; supplementary problem-solving can reinforce database concepts.
