Understanding JDBC: Which statement about Java Database Connectivity (JDBC) is accurate with respect to purpose and design?

Introduction / Context:
JDBC is the standard Java API for interacting with relational databases. It abstracts vendor-specific protocols via drivers, allowing Java applications to execute SQL and manage connections in a portable way.

Given Data / Assumptions:

• Audience: Java developers connecting to RDBMS systems.
• JDBC defines interfaces and classes in the Java language.
• Vendors supply JDBC drivers that implement the API.

Concept / Approach:

JDBC is conceptually similar to ODBC (Open Database Connectivity) in that both define a standard interface to access different databases through drivers. However, JDBC is Java-specific; it is not language independent and is not intended for non-Java languages.

Step-by-Step Solution:

Verification / Alternative check:

Review JDBC architecture diagrams showing JDBC API → Driver Manager → JDBC Driver → DBMS, analogous to ODBC APIs and drivers.

Why Other Options Are Wrong:

Language independent / useful for all OO languages: false; JDBC is for Java.

Three main layers: oversimplification and not a canonical truth for JDBC itself.

Common Pitfalls:

Confusing the JDBC-ODBC bridge (deprecated) with general JDBC usage; assuming drivers behave identically across vendors without testing.

Final Answer:

It is similar in concept to ODBC.
