  1. What is JDBC?  
    JDBC is Java application programming interface that allows the Java programmers to access database management system from Java code. It was developed by JavaSoft, a subsidiary of Sun Microsystems.
        
  2. Product Components of  JDBC    
    JDBC is consists of four Components: The JDBC API, JDBC Driver Manager, The JDBC Test Suite and JDBC-ODBC Bridge.
      
  3. Understanding JDBC Architecture     
    JDBC is an API specification developed by Sun Microsystems that defines a uniform interface for accessing various relational databases. JDBC is a core part of the Java platform and is included in the standard JDK distribution.
        
  4. JDBC Driver and Its Types   
    The JDBC DriverManager class defines objects which can connect Java applications to a JDBC driver. DriverManager has traditionally been the backbone of the JDBC architecture. It is quite small and simple.

  17. Introduction to the java.sql Package
    This package provides the APIs for accessing and processing data which is stored in the database especially relational database by using the java programming language. It includes a framework where we different drivers can be installed dynamically to access different databases especially relational databases.     
      
  18. Understanding Driver Manager
     The main responsibility of  JDBC database driver is to load all the drivers found in the system properly as well as to select the most  appropriate driver from opening a connection to a database.  The Driver Manager also helps to select the most appropriate driver from the previously loaded drivers when a new open database is connected.  
      
  19. Understanding Data Source 
    DataSource object can be thought as a factory for making connections to the particular database that the DataSource instance represents.  
        
  20. Understanding the Connection Object
    A Connection object represents a connection with a database with a database. When we connect to a database by using connection method, we create a Connection Object, which represents the connection to the database.  
               
  21. JDBC Steps in writing JDBC applications
    This section gives you brief description of JDBC Steps for making connection with the database, executing the query and showing the data to the user.
