ADO Means Freedom From Coding Minutiae-O'Reilly Author Guides the Way
Sebastopol, CA--ADO (ActiveX Data Objects) is part of Microsoft's
philosophy of Universal Data Access (UDA), which is neither a tangible
product nor technology, but a strategy for attacking the problem of
data access, explains Jason T. Roff, author of ADO: ActiveX Data
Objects (O'Reilly, US $44.95). In simple terms, UDA and, consequently,
ADO are meant to eliminate the need to convert existing data from one
proprietary format to another. To understand the beauty of using ADO,
you have to imagine programming without it. For example, if you were
designing an application that needed to search Word documents, email
messages, and a SQL Server database for keywords, and then show results
based on that query, you would spend a great deal of time in
development learning about and writing code for each format. With ADO,
you can create a component to search all three data sources using
identical code.
The simple, concise, and efficient architecture of ADO have made it
extremely popular with both programmers new to ADO and longtime users.
ADO: ActiveX Data Objects addresses both groups with two books in
one: an indispensable tutorial combined with a reference that takes a
comprehensive look at the objects, collections, methods, and properties
of ADO. Roff begins by providing a solid introduction to ADO, touching
on the history and theory behind it, then delves into its practical
application. Roff offers an abundance of useful code examples that show
how to use ADO's strong points most effectively.
Although ADO: ActiveX Data
Objects was written primarily for
developers, Roff notes that the audience for his book is wide ranging.
He shares an encounter with a doctor during the writing of his book, "I
recently had surgery on my arm by a plastic surgeon who codes by night.
When he found out that I was a developer, he started asking me ADO
questions--he didn't believe me when I told him I was writing a book
about ADO. I gave him a preview of the book and he was impressed by how
much it helped him simply to understand what ADO was all about. He told
me, 'All the other books I looked at were either poorly written or
operated on the assumption that the reader was not a plastic surgeon
masquerading as a VB developer.'"
Roff adds that he hopes his book will provide an understanding of the
original goals of ADO: "Language independence, data source
independence. I hope to give developers the ability to leverage their
knowledge of ADO in one language while developing in another. I'm a
Visual Basic developer at heart--but I was able to pump out code that
used ADO in Jscript, VBScript, C++ and even Java."
ADO: ActiveX Data
Objects provides essential information on ADO
through Version 2.6, including the following:
Chapters dedicated to the Connection, Recordset, Field, and Command
objects and the Properties collection A complete, detailed reference listing every ADO object, method,
property, and event, in convenient alphabetical order Chapters on ADO architecture, data shaping, the ADO Event Model
An appendix containing enumeration tables used by ADO objects and
collections, listed alphabetically Brief introductions to RDS, ADO.NET, and SQL
With regard to ADO.NET, Roff says, "ADO will be around for many, many
years to come, and will continue to be a very versatile, fast and easy
way to develop database applications--even through our migration to
VB.NET and ADO.NET."
