Data conversion refers to converting from one format to another computer data. The data are encoded in many ways in the IT environment - hardware reads a certain type of data, operating systems handle one another, while other applications can process data in other formats. When a variable is changed data should be converted into a format that matches the environment it must be read / manipulated - for example by an application or another OS. Even the versions of the software may change the demand for data to be transformed into a new structure.
The conversion of data can vary in complexity from a simple text file conversions character encoding for complex conversions, such as desktop image file format conversion, audio file, so that data can sometimes be seamlessly converted or using special programs written for this purpose or the can be done in stages with the procedures for export / import. There are programs that recognize the conversion of data in various formats and can also save them in different output formats.
Some basic concepts should be included in the conversion of the following information:
* While the information can easily be dropped by a computer, it is difficult to add additional information.
* It can add information to base line
* "Oversampling" data allows more information to add, should also be made by actual human intervention
Example - while it is easy to turn a color image to grayscale conversely, a complex process.
The purpose of data conversion is intended that all data and information are included. To be successful, there must be a full understanding of the source and target data formats. If this is not possible to reverse engineering can be used for data conversion takes place.
