Create a class ContactDAOImpl in package which implements ContactDAO.
#How to install jdbc driver for mysql in linux how to#
The examples which we are going to take while explaining how to handle databases will practically show the power of DAOs. It provides data operations without exposing the actual implementations.
DAO is a Data Access Object which provides an interface to the database or persistence mechanism. Create a new interface as ContactDAO in package as follows:. Create or copy the Contact and Gender POJOs which we used in previous examples. Create a new Java application Ch04_ContactManagement. Fire the query using PreparedStatement to insert a record. Let's look at a JDBC application which will insert contact details in the MySQL database using Type 4 driver with the help of the following steps: As Type 4 driver is specific to the database, whenever the database changes the driver has to be changed accordingly. #How to install jdbc driver for mysql in linux drivers#
The disadvantage of the Java Drivers is as follows:
The conversion of calls is from JDBC API to database-specific calls, leading to the best performance among all other drivers. The advantage of Java drivers is as follows: Pure Java driver Advantage of Java drivers The Type 4 driver converts JDBC calls directly to the database-specific protocol with minimum conversions. The Type 4 drivers are also called pure Java drivers as they are completely written in Java. #How to install jdbc driver for mysql in linux code#
It can be used for web applications as there is no client-specific code or configurationĭisadvantages of the JDBC Net Protocol DriverĪs the Type 3 driver uses a middleware server, it's required to install a separate server application where database-specific coding needs to be performed. #How to install jdbc driver for mysql in linux portable#
It is portable as it is written in Java. Unlike the Type 2 driver, in the Type 3 driver there is no need for a vendor-specific database library to be present on each and every machine. The advantages of using the JDBC Net Protocol Driver are as follows: JDBC Net Protocol Driver Advantages of the JDBC Net Protocol Driver The JDBC application will send the request to this middleware server, which translates JDBC calls to the respective database. The Type 3 is useful in the case of a middleware server. The communication with the database server is dependent upon the native API, which leads to problems when the database changes. As a vendor-specific native API must be installed on each client machine, it leads to problems using it for the Internet. The disadvantages of using the JDBC Native API Driver are as follows: In comparison with the Type 1 driver, it gives better performanceĭisadvantages of the JDBC Native API Driver. The advantage of using the JDBC Native API Driver is as follows: JDBC Native API Driver/Partly JAVA Driver Advantages of the JDBC Native API Driver It needs some binary code to be present on the client machine to have communication with the database server. The Type 2 Driver converts JDBC calls to the native calls of the database API, which are database specific. JDBC Native API Driver/Partly Java Driver This leads to restricting the use of the application to desktops. 
The Type 1 driver uses DSN, which needs to be created on every client machine to connect with a database.The JDBC-ODBC Driver uses system installations so in order to use a Type 1 driver, the ODBC driver needs to be installed on the client system.As there are a high number of conversions, the working of the driver is slow, which hampers performance. When a program executes the JDBC, the call gets converted first of all to JDBC-ODBC and then later from JDBC-ODBC to ODBC.The disadvantages of using the JDBC-ODBC bridge driver are as follows: Disadvantages of the JDBC-ODBC bridge driver These types of drivers are freely installed on the system, which allows access to almost all types of databases. JDBC-ODBC bridge driver Advantages of the JDBC-ODBC bridge driver In order to connect to the database it uses an ODBC driver with the help of Data Source Name ( DSN). The Type 1 driver is installed on the client machine which translates all the JDBC calls into ODBC calls. The Type 1 driver uses JDBC API to the Open Database Connectivity ( ODBC) API to access a database. We shall now see all types of driver and their advantages and disadvantages. JDBC Native API Driver / Partly JAVA Driver.The four types of drivers that facilitate JDBC programming on the variety of platforms and operating systems are as follows: The JDBC driver is an implementation that defines the interface in JDBC API for interacting with the database server.
