The release of ADO revolutionized data access by providing a universal means of accessing data from both relational and non-relational sources. ADO has been growing steadily in functionality since its inception: ADO 2.1 added extensions for data definition and security, and support for multi-dimensional data. ADO 2.5, released with Windows 2000, adds even more functionality, including two completely new objects for manipulating streams of text or binary data, and for managing objects within the file system. It also includes an improved data provider for accessing web resources. This book will cover in depth all aspects of programming with ADO 2.5, and provide you with all the information you need to exploit this exciting new technology to the full in your data-centric applications.
