XML, Extensible Markup Language, is an open, text based markup language that provides structural and semantic information to data. XML is a metalanguage that can be used to create other language. It is used to structure and describe data that can be understood by other applications. Using XML, we can separate the user interface from data.

Features of XML :

- XML is a generalized markup language that means one can define his/her own tag sets.

- A valid XML document contains rules and is self-describing.

- The rules that are found in DTD allow the documents to be validated.

- The Dictionary class is an abstract class.

- Classes like Hashtable which map keys to values inherit from this class. 

- An object can be looked for if a dictionary and a key is provided.

- Any non-null object can be used as a key and as a value.

The status of an activity can be start and stop only. The start means the activity is up and running. It is in execution state and performing some actions. Whereas the stop state defines that the activity is being stopped and performing no action on the system. To see or check the status of an activity there is a command that has to be used like NEW_TASK_LAUNCH flag that keeps the track of all the activities that are running and the main command under which the flag resides is given as startActivity() call. To bring the activity stack in front of the process that is already running require the command mentioned above to be used. The activity can be started remotely by using the remote services. These services allow easy interaction with the client and provide the sample to show it on the local server.

PROBLEMS:

i) If the user forgets to opt for keep session then the session will be automatically removed from the session queue(log remains). However if session is processed we may delete it manually.

ii)if session processing fails data will not be transferred to SAP database table.
