This book is for executives, practitioners, and project managers who are tasked with the movement of data from old systems to a new repository. It uses a series of steps developed in real life situations that will get the reader from an empty new system to one that is populated, working and backed by the user population. This new edition of the primary text on the subject is updated to take account of changes in technology and the maturing of the market for data migration services. The most recent figures suggest that nearly 40% of data migration projects are over time, over budget or fail entirely. Using the proven methodology in Practical data migration will vastly increase the chances of achieving on time, on budget, and zero defect migrations. Это и многое другое вы найдете в книге Practical Data Migration (Johny Morris)
