  • design model
  • user’s model
  • mental image
  • system image
Answer: user’s model
Explaination:
to build an effective user interface, all design should begin with an understanding of the intended users, including their profiles of their age, physical abilities, education, etc.
Q9 | What combines the outward manifestation of the computer-based system , coupled with all supporting information that describe system syntax and semantics?
  • mental image
  • interface design
  • system image
  • interface validation
Answer: system image
Explaination:
when the system image and the system perception are coincident, users generally feel comfortable with the software and use it effectively.
Q10 | Which of the following is used to access the database server at the time of executing the program and get the data from the server accordingly?
  • embedded sql
  • dynamic sql
  • sql declarations
  • sql data analysis
Answer: dynamic sql
Explaination:
embedded sql, the sql statements are identified at compile time using a preprocessor. the preprocessor submits the sql statements to the database system for
Q11 | Which of the following header must be included in java program to establish database connectivity using JDBC ?
  • import java.sql.*;
  • import java.sql.odbc.jdbc.*;
  • import java.jdbc.*;
  • import java.sql.jdbc.*;
Answer: import java.sql.*;
Explaination:
the java program must import java.sql.*, which contains the interface definitions for the functionality provided by jdbc.
Q12 | Which of the following invokes functions in sql?
  • prepared statements
  • connection statement
  • callable statements
  • all of the mentioned
Answer: callable statements
Explaination:
jdbc provides a callable statement interface that allows invocation of sql stored procedures and functions.
Q13 | Which of the following function is used to find the column count of the particular resultset?
  • getmetadata()
  • metadata()
  • getcolumn()
  • get count()
Answer: getmetadata()
Explaination:
the interface resultset
Q14 | Which of the following is a following statement is a prepared statements?
  • insert into department values(?,?,?)
  • insert into department values(x,x,x)
  • sqlsetconnectoption(conn, sql autocommit, 0)
  • sqltransact(conn, sql rollback)
Answer: insert into department values(?,?,?)
Explaination:
? is used as a placeholder whose value can be provided later.
