The examples predominantly use Oracle 9i/10g syntax. As of 2026, many institutions teach PostgreSQL or MySQL 8.0. The book lacks coverage of window functions (ROW_NUMBER, RANK), CTEs (WITH clauses), JSON in SQL, or modern indexing (e.g., hash joins, covering indexes). Moreover, NoSQL databases (MongoDB, Cassandra, Redis) receive only a cursory mention, despite their industry relevance.
However, unlike Elmasri & Navathe’s Fundamentals of Database Systems , which emphasizes conceptual depth and theoretical rigor, Chopra’s text is more exam-oriented . It includes chapter-wise question banks, multiple-choice questions, and previous years’ solved papers — a feature highly valued in Indian technical education but less common in international textbooks. a. Hands-on SQL and PL/SQL The book dedicates nearly 40% of its content to SQL (DDL, DML, DCL), joins, subqueries, views, indexes, and PL/SQL constructs like cursors, exceptions, and stored procedures. Each SQL statement is illustrated with an example database (e.g., employee, student, bank). This repetition aids retention. For a student who learns by typing queries, Chopra’s examples are immediately usable. The examples predominantly use Oracle 9i/10g syntax
User reviews on academic forums indicate occasional errors in SQL output, missing parentheses in PL/SQL examples, and inconsistent diagram labeling. The ER notation used is not entirely consistent with Chen’s original or Crow’s foot notation, which can confuse beginners. missing parentheses in PL/SQL examples
Chopra explains ACID properties, schedules, serializability, locking protocols, and timestamp-based concurrency control using simple numerical examples. Compared to Korth’s Database System Concepts , which can overwhelm beginners with formal proofs, Chopra’s version is digestible for a semester course. and inconsistent diagram labeling.
