Data Validation and Migration-A Theoretical Perspective

Data is growing at a rapid rate with ever increasing features and end users. The widespread use of computers and the dramatic evolution in technologies in many large-scale organisations have led to the creation of a number of various application-specific databases to be developed. As organisational systems alter, departmental boundaries move, generating separate sector units. They will use existing data from separate data stores instead of entering the enterprise with new data. The capacity to make data collection interoperable is now becoming a crucial factor in the production of modern information systems. There may be differing degrees of interoperability of data. Commercial gateways bind specific pairs of database management systems to the lowest level (DBMSs). In any case, it is important to have quick access and faster data retrieval.
