Can we use SQL for java language?
No. SQL stands for Structured Query Language and that in itself is a language and it is totally different from Java. However, you can use SQL queries inside Java code with the help of JDBC (Java DataBase Connectivity). But the Java compiler cannot understand/compile standalone SQL syntax unless it is used as part of JDBC.
What is marshalling and Demarshalling?
data marshalling in java means that the structured data item is flattening and converted into external representation data demarshalling is the process of convert the data back to the internal representation and rebuild the data structures.
How can you connet java with sql in java programming?
JDBC mean Java Database Connectivity. In java, using JDBC drivers, we can connect to database. Steps to connect to JDBC. 1) Load the driver, using Class.forName(DriverName); 2) Get the connection object, Connection con = Driver.getConnection(loaded driver name); 3) Create a SQL statement, Statement s = con.createStatement(); 4) Create Resultset object using the statement created above, ResultSet rs = s.executeQuery("sql statement"); Iterate the result set to get all the values from the database. Finally don't miss this 5) s.close(); 6) con.close() ;

Difference between Object-based Data Model and Record-based Data Model?
Object-based data model represents data as objects with attributes and methods, providing a way to model real-world entities in a programming language like Java. On the other hand, record-based data model organizes data into fixed-format records or tuples, typically used in databases like SQL to store and retrieve structured information. Object-based data model offers a more dynamic and flexible way to represent data compared to the rigid structure of record-based models.
