Data processing. Describe data processing steps

Data processing.
1.Describe data processing steps.
Data processing is the collecting and manipulation of data into the usable and desired form. The manipulation is nothing but processing, which is carried either manually or automatically in a predefined sequence of operations. In past, it is done by manually which is time-consuming and may have the possibility of errors during in processing, so now most of the processing is done automatically by using
computers, which do the fast processing and gives you the correct result.
The next point is converting to the desired form, the collected data is processed and converted to the desired form according to the application requirements, that means converting the data into useful information which could use in the application to perform some task. The Input of the processing is the collection of data from different sources like text file data, excel file data, database, even unstructured data like images, audio clips, video clips, GPRS data, and so on. The commonly available data processing tools are Hadoop, Storm, HPCC, Qubole, Statwing, CouchDB and so all.
And the output of the data processing is meaningful information that could be in different forms like a table, image, charts, graph, vector file, audio and so all
format obtained depending on the application or software required.
This broadly divided into 6 basic steps as following
discussion given below.
 Data Collection
 Storage of Data
 Sorting of Data
 Processing of Data
 Data Analysis
 Data Presentation and conclusions
2.What database software do you know ? 
There are mainly three methods used to process the data, these are Manual, Mechanical, and Electronic.
1. Manual: In this method data is processed manually. The entire processing task like calculation, sorting and filtering, and logical operations are performed manually without using any tool or electronic devices or automation software.
2. Mechanical – In this method data is not processed manually but done with the help of very simple electronic devices and a mechanical device for example calculator and typewriters.
3. Electronic – This is the fastest method of data processing and also modern technology with the modern required features like highest reliability and
accuracy. This method is achieved by the set of programs or software which run on computers.
