We can get odbc driver from three vendors. We can get jdbc driver from three vendors :(a)
Some other JDBC driver directly interacts with database software. Some jdbc driver internally uses odbc driver support while interacting with database software. We cannot use ODBC driver directly in our java applications. Non java application use odbc driver to interact with database software. It converts java calls to database calls and vice versa. We need jdbc diver as bridge between java application and database software. To get interaction between operating system and external devices of computer like printer we need support of external device of computer like printer we need device driver. Eg:– Banking application, Insurance application etc.

Conclusion: Use files as persistence store in small scale application Use database software as persistence store in large scale application. Merging and comparison of data is very easy and etc. The Advantages are: Security Sql support Allows to apply constraints, allow to define relationship. To overcome these problems use database software as persistence store. Merging and comparison of data is very complex.

Update and delete operation are very complex. Limitations with files as persistence stores: No Security. Deserialization :=> Reading data form file and constructing object having that data is called deserialization. Serialization & Deserialization Java Application jdbc(sql queries) DataBase SoftWare(RDBMS) (oracle, Sybase, mysql -) Serialization => Process of capturing object data and writing that data to file is called serialization. Save result, inputs to Db table persistence logic I/O Stream Java Application Generating ranks for students service logic. Sample Application: Read student details like no, name, marks (3 subjects) presentation logic. The logic that persist data is called persistence logic. The logic that generates result is called business logic/service logic. The logic that provides user-interface to end user to view result to supply inputs is called presentation logic. Eg:- JDBC, Hibernate (Framework), spring jdbc(framework) Every application contains some logic like presentation, business, service and persistence logic and etc. The technology that can be used to develop persistence logic is called persistence technologies.

Eg:- IO Steam code, JDBC code hibernate code. The logic that is used to perform persistence operation is called persistence logic. These are also called CURD/CRUD/SCUD operations. The insert, update, delete and select operations performed on persistence data is called persistence operations. Terminologies:The place where data will be saved and managed is called persistence store Persistence Store:The data of persistence store is called persistence data. Persistence Technology CRUD/CURD/SCUD o C-Create(insert) o R- Read (select) o U-Update(modify) o D- Delete In order to overcome this problem we should write application data to secondary memory like hard disk to persistence. This data, memory vanished once the application is completed because RAM is temporary memory. The data stored in variables, objects of application allocates memory in different part of RAM only during the application execution. The process of saving and managing data for long time is called persistence. Utility api(java.util and its sub package) Jdbc api(java.sql, javax.sql and its sub packges) JDBC : => Persistence : => Saving data for long time and manage data for long time is called persistence. Third party APIs (given by other than above two) Popular Java APIs(built in api) (i)īuilt-in APIs (given by language/technology/framework) In java API means classes, interfaces, enums, annotations which come in form of packages. C++ API means set of functions, classes which comes in the form of header files. In c language API mean set of function which is in the form of header files. Every language technology and framework gives different API. APIs are base for developers to develop software applications. It is used Having English meaning based/platform API: Application Programming Interface Here the word interface is no way related to java interface. Q:- How can we develop java application without main method? Ans:public class DemoApp1 The above code runs in all java versions up to jdk1.6 and in the initial release of jdk1.7 but not in other version.
b)In the process of creating first object for the class. JDBC a)When it is given to begin the execution.
