I'm a software program developer of over 30 years. whereas i'm new to SQL server, i've been doing DBMS developement for over 15 years.

I gave up in this publication by means of web page fifty five. i discovered the fashion plodding with basically marginally necessary analogies. however the genuine challenge used to be a sequence of muddled, deceptive and downright misguided statements and references. There are too many to checklist all of them right here, yet a couple of examples:

Muddled on p 50: "You can create extra indexes for a desk, unique at sure columns. a number of indexes require extra assets, even though, so that you have to be conservative and restrict new indexes to columns you recognize are usually searched on. In different phrases, no rows may have exact values for the index key." What does the 3rd assertion need to do with the 1st two?

Inaccurate on web page forty eight, determine 2-7 exhibits tables, however the caption refers to 3 tables and utilizing A, B and C for names/labels which don't look within the determine: "The fundamental key in desk A hyperlinks the row to the rows in Tables B and C, which undergo the international keys. All 3 rows mix to shape a special checklist. if you happen to delete one of many rows, you certainly holiday the checklist and destroy the integrity of your data." The final assertion is at top deceptive, at worst inaccurate.

In discussing Constraints (NOT NULL) on p fifty two: "As mentioned prior, NULL signifies that the list is deemed to be unknown or missing." really, the worth of a column for the row is unknown or lacking, now not the total record.

I can't depend on the knowledge I examine from a e-book that includes such difficulties and can't suggest it to acquaintances.

Example text

Client/server is the dominant model employed, and this is fast transforming into the new model of thin-client/server computing. While it seems we have come full circle, clients no longer need to be more than the weight of their user interface. Almost 100 percent of the functionality and processing resides at the server. Our networked and highly distributed world demands that software product be built according to interoperable client/server component systems. In this regard, the relational database products of yesteryear, which dump a huge footprint of code and functionality on a user’s desktop computer, are out of touch with reality; essentially obsolete.

SQL Server 2000 includes a robust XML parser, which translates XML in your queries to retrieve data. Conversely, SQL Server is able to return the data to the requesting client applications as XML data, as opposed to the rowset or recordset typical of traditional database applications. This has applications on both intranets and the Internet. But SQL Server does not only understand how to read an XML-based query; it is also able to store data as XML. It can provide a relational view of the data as well as map XML data into tables.

A collection of databases can be managed as a unit by a single instance of SQL Server. Systemwide management features include functions such as backup/restore, logins and security, replication, and data transformation. To talk to SQL Server—that is, to ask it to save data, change it, return it, process it—you need to know SQL (or more accurately, Transact-SQL; but more about this in a moment). SQL is the international standards–supported computer language of the relational database. It is represented by ANSI (the American National Standards Institute) as well as the ISO (the International Standards Organization).
