This is a data warehouse application. And we are implementing statistical models like Actuarial, Pulse, Risk Stratification and etc. to analyze huge amount of records. We normalize the data and calculate skewness and different related parameters for procedure tracking, disability, Inpatient and Actuarial Prediction in member wise by processing atomic data. Ab initio, a data warehouse tool generates the input file for our application. Since we have to process millions of records, edging for performance is the major challenge. We are extensively using STL libraries. At end, process creates a output file and Ab Initio upload the file into non-atomic tables within the warehouse. Those data may be using by different clinical applications.

Task Management API supports  all OSEK-OS Standard,  and this includes the check the every   functionality of following Task Management of TickOSEK RTOS.

-          

-         Time management API  includes:

-         TimeDly( ) allows the calling task to delay itself for a user-specified number of clock ticks.

-         TimeDlyHMSM( ) can specify time in hours (H), minutes (M), seconds (S), and milliseconds (ms). 

-         TimeDlyResume( ) use to a delay task and that can be made ready to run by another task that cancels the delay.

-         TimeGet obtain the current value of the counter.

-         TimeSet change the value of the counter

-          

-         Task Management API includes:

-         ActivateTask( ) use to create a new task.

-         TerminateTask( ) use to terminate a calling task.

-         ChainTask( ) use to terminate the calling task. After termination of the calling tasks a succeeding task <TaskID> is activated.

-         GetTaskID( ) returns the information about the TaskID of the task which is currently running. 

-         GetTaskState( ) returns the state of a task (running, ready, waiting, suspended) at the time of calling GetTaskState.

-         Schedule ( ) If a higher-priority task is ready, the internal resource of the task is released, the current task is put into the ready state, its context is saved and the higher-priority task is executed. Otherwise the calling task is continued.
