A Records Management System is a computer program or set of programs used to manage and store records.

For example, a hospital record for storing new room, ward , patients, etc...

- Web servers can be infiltrated using the command shell by an attacker to read the HTML files that is getting transferred. 

- If the set-uid scripts are not proper and bad then the infiltration can happen by the attacker. 

- The processes are not given proper permissions so that the password can be changed by using the “passwd” command to change the password of the system.

- This also authenticates the user for accessing the system and the files on it containing the data. 

- The program that is used in the operating system doesn’t follow the principle of least privilege and lead to security issues.

To do multi threading in java we use interfaces and classes defined in java.lang package.

Those classes and interfaces are:

Java.lang.Runnable, Java.lang. Thread, Java.lang.ThreadGroup

Priority: concern with application from the business point of view. It answers  How quickly we need to fix the bug? Or How soon the bug should get fixed?

Severity: concern with functionality of application. It deals with the impact of the bug on the application.

new ClassName( arg1, arg2, .... argN);

Ex:

Class sample {

   Sample(int a) {

   System.out.println("arg con a =" +a);

   }

}

class Demo {

    Public static void main( String[] args) {

     Sample s1= new Sample(23);

     Sample s2= new Sample(45);

    }

}

API stands for Application programming interface is very useful in cloud platforms as it allows easy implementation of it on the system. It removes the need to write full fledged programs. It provides the instructions to make the communication between one or more applications. It also allows easy to create application with ease and link the cloud services with other systems.

Call Transaction Method: In Call Transaction method we call the transaction in BDC program itself. If we want this program is executed by some one else then we need to expose the code to him. Call Transaction Method Works in Foreground. No Display Mode is equal to Background Processing in call transaction method. Call Transaction Method can handle only one Application at a time. In Call Transaction Method no Log File by Default. We have to design Log File by using BDCMSGCOLL. Call Transaction Method Updates the Database Asynchronously. (Note: Asynchronous updation is Faster than Synchronous)
 
Batch Session Method: On the other hand in batch session method we create a session which can be executed at any time by any authorized person without exposing the code of the program. Session Method works in Background and as well as in Foreground. Session Method can handle Multiple Applications at a time. Session Method holds Log File by Default. Session Method Updates the Database Synchronously.

public delegate void Del<T>(T item);

Del<int> d1 = new Del<int>(Notify);
