Data Processing means performing a series of steps to change or preserve the form of data. Data Processing is performed using an established procedure. Generally, a Computer Program, that is implemented using a programming paradigm, performs the task of Data Processing. The different streams of job responsibilities, that are part and parcel of Data Processing, are briefly highlighted: ( 1 ) Processing of large quantities of Experimental Results that are part of Scientific Research. ( 2 ) Processing of Personal Information. ( 3 ) Applying programming techniques to Multiple Data Streams. ( 4 ) Operations on Production Level Data. ( 5 ) Making Sales Forecasts. ( 6 ) Generation of Pivot Reports. ( 7 ) Analysis of Investment Plans. ( 8 ) Preparation of Orders. ______________________ ______________________ Data Processing tasks are performed at organisational level necessitating deployment of Computer Applications. Computer Applications are empowered to process large quantities of data....
