Q) What are the limitations of procedure oriented programming methodology?



A)

Data processing sake we write a program. The problem of processing or particular program application is nothing but program.
Application = data + code
       Difference between procedure oriented and oop methodologies
In procedure oriented the data and code is not organized but in oop the data and code is organized.
The process/procedure of way is important but not important to data.
=> Any application is primarily ment for processing of data. To process data we need to have    instructions (code).
      Therefore, we say that an application is comprises of data and code that acts upon data.
      The way to process is important in procedure oriented.
      The main problem with procedure oriented is the code and data is not property organization.
      The lake of organization of code and data become many problems.
=> Procedural orientation is one kind of programming principle. According to his principle, given            importance. But not “what data is” and “who is processing data “.
=> In procedural oriented style of application development data and code that acts upon data or not properly organized.
=> Lack of proper organization of data and code leads to the fallowing problems:
1)      Data is not secure (from whom?)
2)      Complexity can’t be handled.

Q) What is JDBC driver? What is its role in java database connection?

A) ->A translation software written in java according o JDBC specification is nothing but “JDBC driver”. -> JDBC driver implements JDBC API. Use single API. JDBC driver role: They are 4 roles   1)       Establishing connection between JDBC client and database server. 2)       Receiving JDBC method calls made by JDBC client while performing database (CRUD) operations. 3)       Translating java method calls into DBMS understandable calls and forwarding them to database server. 4)       Receiving the results from database server.
