JDBC and SQLJ are two different ways of interacting with a database. JDBC is a Java-based application programming interface (API) that is used to access and manipulate data in a relational database. It is a low-level API that provides access to the underlying database system. SQLJ is a high-level Java-based language that is used to write SQL queries. It is similar to SQL, but it is written in Java and can be used to access data from multiple databases.
JDBC is a standard API for accessing relational databases, and it provides a set of classes and interfaces for writing Java programs. It is a low-level API that provides access to the underlying database system. It is used to create and execute SQL statements, retrieve and update data, and manage transactions.
SQLJ is a high-level Java-based language that is used to write SQL queries. It is similar to SQL, but it is written in Java and can be used to access data from multiple databases. It provides a set of classes and interfaces to create and execute SQL queries. It also provides a set of tools to generate dynamic SQL statements.
In summary, JDBC is a low-level API that is used to access and manipulate data in a relational database, while SQLJ is a high-level language that is used to write SQL queries. Both are used to access data from multiple databases, but JDBC is more suited for accessing relational databases, while SQLJ is better for writing SQL queries.
