Data processing is a shop that works in many different working fields. One thing you do in data processing is learning to computer programming. In my shop we are learning to program in Visual Basic and QuickBasic. Programming is used to tell a computer what to do. Using code you can make programs that can answer math problems‚ which would take someone‚ days to calculate in a brief second. In data processing we also learn to word process. Word processing is taking written text and being able to save

occurred in using the file-based approach: Separation and isolation of data When data is isolated in separate files‚ it is more difficult for us to access data that should be available. The application programmer is required to synchronize the processing of two or more files to ensure the correct data is extracted. Duplication of data When employing the decentralized file-based approach‚ the uncontrolled duplication of data is occurred. Uncontrolled duplication of data is undesirable because:

Several theories are particularly relevant to logistics outsourcing practices and decision strategies: (1) Transaction-Costs Analysis (TCA) and Agency Theory; (2) Resource-Based Theory (RBT); and (3) Network Theory (NT) and General Systems Theory. Transaction costs refer to the costs of physical and human resources incurred in order to complete an exchange of goods and services between parties. Factors that contribute to these costs

INFORMATION PROCESSING THEORY Information processing is a cognitive theoretical framework that focuses on how knowledge enters and is stored and retrieved from our memory.
