Beginner-Friendly:

#

1. “Database System Concepts”
   — by Abraham Silberschatz, Henry Korth, S. Sudarshan
   ➔ A classic. Very clear explanations of relational algebra, relational calculus, and SQL.
   ➔ Covers theory + practical examples.

2. “Fundamentals of Database Systems”
   — by Ramez Elmasri and Shamkant Navathe
   ➔ Very detailed. Good for understanding how relational algebra connects to real database systems.

3. “Learning SQL”
   — by Alan Beaulieu
   ➔ If you want to quickly become comfortable with querying databases (SQL), this book is simple and practical.

For deeper Theory:

#

4. “Principles of Database and Knowledge-Base Systems”
   — by Jeffrey D. Ullman
   ➔ Heavy on relational algebra, relational calculus, and logic foundations.
   ➔ Best if you like a more mathematical approach.

5. “Foundations of Databases”
   — by Serge Abiteboul, Richard Hull, Victor Vianu
   ➔ Advanced and theoretical.

  ➔ Some versions and lecture notes are available online.
  ➔ Well-explained relational algebra with many examples.

If you want a short plan:

#

• First Silberschatz ➔ easy intro + relational algebra basics.
• Then Elmasri/Navathe ➔ details, SQL + design + normalization.
• Then Ullman ➔ if you want deeper mathematical knowledge.
