Which tool is used to create relational connections?

What is ODBC and how it works?
Driver, which processes ODBC function calls, submits SQL requests to a specific data source, and returns results to the application. Data source, which consists of the data to access and its associated operating system, DBMS, and network platform (if any) used to access the DBMS.
What is difference between ODBC and JDBC?
JDBC and ODBC, both are the API (Application Programming Interface) that help the applications on the client side to access the database on the server side. The point that fundamentally differentiates JDBC and ODBC is that JDBC is language dependent and it is Java specific whereas, the ODBC is a language independent.
Is ODBC faster than JDBC?
JDBC drivers are implemented in Java. ODBC drivers are faster. JDBC drivers are slower than ODBC drivers. ODBC is procedural.
Where is ODBC used?
An ODBC driver uses the Open Database Connectivity (ODBC) interface by Microsoft that allows applications to access data in database management systems (DBMS) using SQL as a standard for accessing the data. ODBC permits maximum interoperability, which means a single application can access different DBMS.
What are the 4 types of JDBC drivers?
There are 4 types of JDBC drivers:
- Type-1 driver or JDBC-ODBC bridge driver.
- Type-2 driver or Native-API driver.
- Type-3 driver or Network Protocol driver.
- Type–4 driver or Thin driver.
Which JDBC driver is efficient?
Which driver is efficient and always preferable for using JDBC applications? Type 4 Driver is a Database-Protocol Driver(Pure Java Driver). Its implementation allows the conversion of JDBC calls directly into a vendor-specific database protocol.
What are different types of JDBC drivers?
Today, there are five types of JDBC drivers in use:
- Type 1: JDBC-ODBC bridge.
- Type 2: partial Java driver.
- Type 3: pure Java driver for database middleware.
- Type 4: pure Java driver for direct-to-database.
- Type 5: highly-functional drivers with superior performance.
Which type of JDBC driver is the fastest one?
Which type of JDBC driver is the fastest one? JDBC Net pure Java driver(Type 4) is the fastest driver because it converts the JDBC calls into vendor specific protocol calls and it directly interacts with the database.
Which of the following is correct for Type 4 driver?
Native-protocol, pure Java driver, is also called Type 4 JDBC driver.
Which packages contain the JDBC classes?
The Java packages which contain JDBC classes and interfaces is Java. SQL.
What does JDBC stand for?
JDBC (Java Database Connectivity) is the Java API that manages connecting to a database, issuing queries and commands, and handling result sets obtained from the database. Released as part of JDK 1.1 in 1997, JDBC was one of the first components developed for the Java persistence layer.
What is in terms of Jdbc a datasource?
WebLogic JDBC data sources provide database access and database connection management. Each data source contains a pool of database connections that are created when the data source is created and at server startup.
Which method needs to be used to execute a DML statement using JDBC?
5) Which of the following method is used to perform DML statements in JDBC? Explanation: We use the executeUpdate() method for DML SQL queries that change data in the database, such as INSERT, UPDATE, and DELETE which do not return a resultset.
Which JDBC method is used to execute queries?
The executeQuery() method of Statement interface is used to execute queries of retrieving values from the database. This method returns the object of ResultSet that can be used to get all the records of a table. The executeUpdate(SQL query) method of statement interface is used to execute queries of updating/inserting.
Which statement is used to execute parameterized queries?
The PreparedStatement interface is a subinterface of Statement. It is used to execute parameterized query.
