Ah, online processing and real-time processing are like two happy little trees in the same forest. Online processing typically involves batch processing where data is collected and then processed in intervals, while real-time processing happens instantly as data is received. Both methods have their own beauty and purpose, just like different brushstrokes on a canvas.
There are different methods of data processing. Some methods are manual data processing, mechanical data processing, online processing, batch processing and electrical data processing.
The main advantage of real-time processing is that you will get results immediately. This will allow one to make quick decisions before too much time is wasted as they are able to monitor the process in real time.
Data processing is basically the transformation of raw data to import data through a procedure. Data is controlled to create results that lead to the goals of an issue or improvement of a current circumstance. Methods of data processing:- Manual Data Processing, Data is processed manually without using any machine or tools to get the required result. Mechanical Data Processing, Data is processed using different devices like a typewriter, mechanical printers, and other devices. Electronic Data Processing, Data is processed through a computer; data & set of instructions are given to the computer as input, and computer-processed data according to given instruction. · Batch processing · Online processing · Distributed processing · Real-time processing
File based approach can be attributed to two factors: 1. the definition of the data is embedded in the application programs, rather than being stored separately and independently. 2. there is no control over the access and manipulation of data beyond that imposed by the application programs. To become more effective, a new approach was required. What emerged were the database and the DBMS (Database management system).
Batch processing generally means using a scripting language to queue one or more jobs that will work one after the other without any manual intervention. That is, the actual processing is automated, the only input required from the user is in order to set up the batch. Contrast with online or interactive data processing which requires user-input throughout the process. In batch processing, the input is typically generated from input files collated as a batch, and the output of one job can often be used as input for the next job, dependant upon the type of processing. Some software includes batch processing modes of their own, but for those that don't, command sequences can be crafted using scripting languages, either from within the program itself (where supported) or externally at operating system level. Operating system command scripts can also be employed for batch processing, hence they are also known as batch files.
what are the different between online and offline Data Processing

There is no difference between the two. No matter how you word it, it means the same. Advertising online and online advertising is only a medium for promotional messages.

Database software and word processing software are different because word processing software allows you to store information on a computer using Excel and Word. Database software allows you to create a web database that allows individuals to see information online.

relevance of on-line analytical processing Relevance of online analytical processing to a manager?
online analytical processing uses basic operations such as slice and dice drilldown and roll up on historical data in order to provide multidimensional analysis of data data mining uses knowledge discovery to find out hidden patterns and association constructing analytical models and presenting mining results with visualization tools.
disadvantages of on line processing?
online processing is done when--------------is not possible in data handling.
