What are the advantages and disadvantages of the Database First approach when working with databases?

Advantages of Database First:

• Allows working with an existing database, which is convenient when integrating with legacy systems.
• Models and context are generated automatically, saving time on manual schema description.
• Ensures an exact match between the model and the database, reducing the likelihood of errors in the structure.

Disadvantages of Database First:

• Less flexibility when changing the model — changes in code require updating the database and regenerating.
• Harder to maintain code cleanliness and readability if the database contains many redundant or outdated tables.
• Dependency on the database structure, which can complicate refactoring and application development.

Thus, Database First is suitable when the database already exists and precise synchronization with it is important, but it is less convenient for active development with frequent model changes.
