Data Conversion and Migration

Considered as the key services in IT industry

, data conversion is includes the conversion of computer data from one format to another and some other. Moreover, the data can be encoded in various ways for the comfort of conversion and migration. Data conversion or migration is essential so that whenever someone changes the variable data must be converted in some way which has to be operated in different computer, operating system or program.

Depending upon the specific requirement data conversion can be easy or tough. At times data conversions can be as simple as the conversion of a text file from one character encoding system to another. Similarly, it can be too complex which even can be like conversion of office file formats, or the conversion of image and audio file formats, etc. Varied kinds of data conversion require different versions of data structures.

In order to carry out data conversion and migration, the user or application programmer is required to keep certain fundamentals of computing and information theory in his head as these are considered essential. The primary understanding is that whereas information can easily be discarded by the computer, any addition of information takes lots of efforts. Additionally, a computer can add information only in a rule-based fashion and not otherwise. The final assessment is that upsampling the data or converting the same to a more feature-rich format not necessarily enhances the information rather enables a space to grow which usually a human must do.

Experts involved in data conversion do data conversion and migration in numerous ways and one of the vogue is that seamless conversion wherein upgrading to a newer version of a computer program with diligence and sincere efforts. In order to do successful conversion of data, the service provider must have thorough knowledge of the workings of both source and target formats. Moreover, where he sees that the specification of a format is unknown; he can take detour and use reverse engineering carry out data conversion.

Experts opine that reverse engineering is useful achieving close approximation of the original specifications. However, errors and missing features can still result in the process and only can be avoided to an extent. Then there are certain other specific requirements for data conversion and depending upon simple to complex requirements solutions are provided to IT firms. Whereas data conversion may be done directly from one format to another, numerous applications used for it may use a pivotal encoding to get to the target. One of the major objectives of data conversion is to secure and maintain data and the embedded information to the extent possible.

Moreover, the securing the data can be done only if the target format supports the same features. Additionally, the other requirement is that the data structures present in the source file matches too with the file to be sourced. One fine example is conversion of a word processing document to a plain text file, in such a case there would be the whole loss of data. Therefore, conversion from one format to another can be done when there is possibility of operatability.
