There are two keys to a successful ETL solution: using the right enterprise ETL tool and employing the right ETL architecture in order to meet the system requirements. With SQL Server 2014 Integration Services, half the battle is won. The out-of-the-box features provide the depth and breadth of functionality and flexibility needed to create scalable solutions. Even more, the usability and rapid learning curve reduce solution development time. The second ingredient is Correct ETL architecture and design. When considerable effort is spent testing scenarios and proving out designs, valuable testing, implementation and deployment time is lost. This book fills that gap. Professional SQL Server 2014 Integration Services , fully cover the new features of the 2014 product release, expected in early 2014. The book is about 20% revised, reflecting changes in how the product looks and works. In addition to technical updates and additions, the authors add a new set of best practices for effective use of SSIS; more case studies and tutorial examples to illustrate advanced concepts and techniques.
