"I don't think much of a man who is not wiser today than he was yesterday" – Abraham Lincoln
To keep up to date with all the technologies in SQL Server, the DBA or developer who wants to stay ahead is faced with the struggle of constant learning. With every new release, it seems that at least one entirely new application platform appears, alongside innumerable additions to, and improvement of, existing features. How do you keep up while avoiding information overload, unnecessary detours and dead-ends?
The SQL Server Stairways is our solution to this problem. Designed to smooth out even the steepest learning curve, each Stairway is a SQL tutorial series focused on a single topic and is arranged into no more than a dozen easily-navigable tutorials that we call 'steps'. Each step is the length of a typical magazine tutorial, and emphasizes practical, hands-on learning, with just enough background theory to help you understand the topic at a deeper level.
Using straightforward language and avoiding jargon and marketing babble, each Stairway tutorial series is designed to take you from zero knowledge of a particular SQL Server topic, to a level of practical understanding that will allow you to start using that feature in a production environment. The learning gradient is steady and manageable, but also brisk. You won't be wasting time.
Our team of Stairway Editors, including Kalen Delaney and Brad McGehee, have selected technical topics that all SQL Server DBAs and developers can benefit from mastering, and have persuaded leading experts in those fields to author them.
We would love to hear any feedback you have on any aspect of the Stairway project, and not least, any suggestions you may have for SQL tutorial topics that you'd like the Stairway series to cover.

IT projects can hit problems that turn out to be due to an insufficient understanding of the basic data and data-types, rather than the database design. It is a sorely neglected topic that might seem to be trivial, but certainly isn't. The DBA, with a broad perspective on corporate data can do a great deal to help application developers to avoid the common mistakes that so often happen, and Joe Celko's Stairway gives the busy IT professional a crash course to understanding the nature of the data being processed.
New to the task of designing and creating a database? Joe Celko, who is one of the most widely read of all writers about SQL, explains the basics. As usual, he comes up with the occasional surprise for even the most seasoned database professional.
Joe was the winner of the DBMS Magazine Reader's Choice Award four consecutive years. He has taught SQL in the US, UK, the Nordic countries, South America and Africa.
He served 10 years on ANSI/ISO SQL Standards Committee and contributed to the SQL-89 and SQL-92 Standards.

Multidimensional Expressions (MDX) is a standard query language, derived from SQL but geared specifically for OLAP databases. It also includes a calculation language, with syntax similar to spreadsheet formulas. It is an important skill for PowerPivot. Bill's new series for MDX starts right at the very beginning and takes us through all the basic functions of MDX, with plenty of practical examples.
Data Analysis Expressions (DAX) is the standard PowerPivot formula language that supports custom calculations in PowerPivot tables and Excel PivotTables. While many of the functions used in Excel are included, DAX also offers additional functions for carrying out dynamic aggregation and other operations with your data. Bill's new series serves as a progressive introduction to PowerPivot and DAX formulas, examining the functions, operators and values involved, and offering a wealth of practical examples.

PowerShell is a powerful scripting tool that allows you to automate routine tasks, and script administrative tasks, allowing you to automate a lot of the routine work in a SQL envirionment. Ben Miller's Stairway Series introduces PowerShell from the beginning, guiding you through how to configure and get started with the framework before working towards more advanced scripting.

Indexes are fundamental to database design, and tell the developer using the database a great deal about the intentions of the designer. Unfortunately indexes are too often added as an afterthought when performance issues appear. Here at last is a simple series of articles that should bring any database professional rapidly 'up to speed' with them

SQL Replication can solve many problems in running database-driven applications. The publication/subscriber model isn't completely easy to understand, the complexities of scripting and monitoring replication systems takes some thought. Here, at last, is a series of articles that takes care to produce a jargon-free approach to SQL Server Replication of all types.

Microsoft StreamInsight™ is designed to assist in developing Complex Event Processing (CEP) applications in .NET This is appropriate for stream sources tsuch as those in manufacturing applications or financial trading applications. StreamInsight provides the means to monitor, manage, and mine several sources simultaneously for conditions,trends, exceptions, opportunities, and defects almost instantly. It is ideal for performing low-latency analytics on the events and triggering response actions, and for mining historical data to continuously refine and improve definitions of alerting conditions. Johan provides a simple explanation of the system in a series of practical articles.

When things are going well, there is no need to be particularly conscious of what the Transaction log does or how it works. You just need to be confident that every database has the correct backup regime in place. When things go wrong, an understanding of the transaction log is important for taking corrective action, particularly when a point-in-time restore of a database is required, urgently! Tony Davis gives just the right level of detail that every DBA should know.

This Stairway will provide you with a basic understanding of how to work with data from SQL Server tables, using SQL Server’s Transact-SQL (T-SQL) dialect. DML is the Data Manipulation Language, and is the aspect of the language dealing with the data. It includes the statements SELECT, INSERT, UPDATE and DELETE. This Stairway will as also provide some history of the SQL language and some general concepts about set theory. Each level will build upon the prior level, so by the time you are finished you will have a good understanding of how to select and modify data from SQL Server.

Although XML is conceptually simple, its use as an equal partner datatype within a relational database, with full searching, validation and manipulation of data, is not intuitive. Now that the industry is more conscious of the use of semi-structured data and data defined by document markup, it is becoming more important than ever for Database Developers and DBAs to become conversant with the technology and appreciative of the cases where XML technologies enhance applications and their development. Robert Sheldon flexes his talent to make the complicated seem simple.
