A unique constraint on a column uniquely identifies the record by a combination of one or more fields. Few unique constraint fields can have a NULL value as long as the combination of values is unique.

Example:
create table employee ( id number NOT NULL, dob DATE, professor_id NOT NULL, Name varchar(200) Constraint id_unique UNIQUE(id,dob) );

- Infinite file consists of random bits of code that is stored in /dev/random file used to generate the cryptographic keys. 

- Infinite file consists of the source of infinite data that can be used to provide the response in easy manner. 

- Web server consists of the file that is received by the server in this format GET //dev/random HTTP/1.0. 

- Web server provides the continuous data that can be read from /dev/random/ before the web server can run out of the memory. 

- The server crashes out in case it runs out of the memory due to the infinite file type and it is very essential in case of the web security.

- The infinite file error can be solved when the data will be read continuously from the file. 

- The error can be solved by using the keys that provide only the resources that are required. 

- The following program is as follows:

osw.write ("HTTP/1.0 200 OK\n\n"); 

while (c != -1) { 

sb.append((char)c); 

c = fr.read(); 

} 

osw.write (sb.toString()); 

- This converts the requested file in such a way that if the file exists it shows the messages as ok otherwise it shows an error.

- Limited file access is to be given to the file to remove the error from the infinite file type.

By using method.

The method used to get the data is called getter method.

A record data type represents a data type for that row in a database table. It lets u define your own records and not your own fields.

Requirements gathering, functional design and business process, change management etc are very critical tasks for a business analyst.
