Résumé
Part I contains a variety of topics that help you get started using DTS in SQL Server 2000. Chapter 1 gives a quick look at DTS. Chapter 2 describes the enhancements made to DTS in moving from SQL Server 7.0 to SQL Server 2000. Chapter 3 describes how DTS can be used to manage the flow of data throughout an organization. Chapter 4 focuses on the use of DTS to load a star schema in a data mart.
Part II begins with a description of DTS connections. You can use Data Transformation Services with any data source that has a conforming OLE DB provider or an ODBC driver. SQL Server 2000 includes OLE DB providers for Microsoft SQL Server, Microsoft Access, Microsoft Excel, Oracle, DB2, Dbase 5, Paradox, HTML files, text files, and for ODBC drivers.
There are 17 chapters in Parts II, III, and IV that describe the DTS tasks in detail. Each chapter has a section that describes when it is appropriate to use a particular task. All the properties of the tasks are described, with a description of how to set properties through the normal interface, through a special tool called Disconnected Edit, with the Dynamic Properties task, with VBScript code, and from a Visual Basic application. A procedure is included for creating each of the tasks in Visual Basic.
There are extensive VBScript samples, showing how to use transformation scripts, scripts in ActiveX Script tasks, and workflow scripts. There are transformation scripts that combine many records into one and one record into many. There are examples for setting up loops in a DTS package. There are scripts for documenting the connections in a package, optimizing transformation column references, setting up package transactions, creating the text of e-mail messages, writing to text files, and setting DTS properties.
Of special note is the chapter on the new Parallel Data Pump task, a task that is used to import hierarchical rowsets. SQL Server 2000 does not provide a user interface for this task, but the author describes how to automate the creation of these tasks, using the existing Transform Data task functionality together with a utility the author has created.
Part V discusses a variety of issues regarding DTS packages and steps. You can learn how to use step precedence, create transactions, use the Copy Database Wizard and the Import/Export Wizard, manage packages from Visual Basic and from SQL Server stored procedures, handle errors in a package and its transformations, and integrate DTS with Meta Data Services.
Part V also has a chapter on high performance DTS packages, which includes tables and charts showing the relative performance of various DTS tasks and options. In some cases you can change DTS performance by a factor of 100 by selecting the appropriate task or the appropriate settings for a task.
Part VI shows how to extend the power of DTS. There are chapters on programming with the DTS object model, creating a custom task with Visual Basic, and creating a custom transformation with Visual C++.

is the chief consultant at SDG Computing, Inc., a company that specializes in data warehousing with Microsoft's SQL Server tools. He has used DTS for data warehousing projects with telecommunications, insurance, manufacturing, and internet companies.
Tim is the designer of the Local Cube Task, a custom DTS
task that automates the process of creating multiple local
cubes. Local cube files allow users to access their OLAP
data when they are disconnected from the network. The Local
Cube Task provides companies a way of efficiently creating
their local cubes. Whenever DTS is used to load new data
into a database, this custom task can be used to create
current copies of the local cubes.
