   hi all,   
   i need to build a system which will find any anomalies of a particular   
   activity. The system will be feeded with events that are happening and   
   it should be able to find any significant deviation from the normal   
   operation. the activities involved are divarse, but so if i can come up   
   with a generic system, i might be able to use in all occations. Some   
   examples of the activities i need to monitor are :   
   1 ) webserver access   
   2 ) sales   
   3 ) access to a particular table in a database   
   4 ) access patterns of various tables in a database, etc   
   5 ) access ( login ) patterns, frequency to a particular system   
      
   this list will be growing.   
      
   basically i need to be alerted on   
      
   deviation of events's frequency from normal   
   deviation in pattern of events that are happening, etc   
      
   i wonder whether there is any area in mathematics / computer science   
   which deal with that kind of problems. So i really appreciate if some   
   one can suggest me a good path for the project.   
      
   thank You.
