6th Annual Financial Services Developer Conference

I went to the 6th Annual Financial Services Developer Conference today in New York City. This year’s focus was on High Performance Computing (HPC). I must say that I have enjoyed this conference a lot. It seems that SQL Server is very prevalent on the street. The OLAP capabilities of SQL Server are making Sybase slowly disappear from Wall Street. Financial firms are doing some very interesting stuff; there is a hedge fund which records an earnings call, runs it through some voice stress analysis software and based on the outcome of that will short or long the stock. You should hear the stories of how financial firms handle IT, the innovation is happening in the financial markets. I also saw a couple of very cool WPF applications. Check out the demos from Lab49: http://www.lab49.com/insidethelab/demos
Visit http://www.financialdevelopers.com/ to download The Silverlight 2 Retail Financial Services Demonstrator



Carl Franklin from Dotnetrocks recorded a podcast at the event, this podcast was about concurrency and how to handle multi-core programming. You should definitely check it out when it becomes available on dotnetrocks. If you are interested about PLINQ and concurrent programming with .NET then visit this site: http://msdn2.microsoft.com/en-us/concurrency/default.aspx



Tomorrow there are three sessions at the same time that I want to attend

I have my blackcrackberry with me so if you are attending the event tomorrow then send me an email at FirstName.LastName@dowjones.com and maybe we can discuss about this event during lunch.

StrataFrame Or CSLA.NET, Which Framework Would You Use?

If you would have to choose between StrataFrame or CSLA.NET, which one would you pick?
The team I am part of at work is trying to pick a framework for new development and they like these two the best. Are these two something you would pick or do you know a better one?

CSLA.NET: http://www.lhotka.net/cslanet/
StrataFrame: http://www.strataframe.net/

Also keep in mind that while CSLA.NET is free, StrataFrame is not.

Video: SQL Server Data Services and the Future of Data in the Cloud

Channel 9 has a 45 minute video with Dave Campbell about SQL Server Data Services. maybe this video will answer some of the question you might have about SQL Server Data Services

Microsoft Announces SQL Server Data Services

What is Microsoft SQL Server Data Services?
SQL Server Data Service (SSDS) is a highly scalable and cost-effective on-demand data storage and query processing web service. It is built on robust SQL Server technologies and helps guarantees a business-ready service level agreement covering high availability, performance and security features. Microsoft SSDS is accessible using standards based protocols (SOAP, REST) for quick provisioning of on-demand data-driven & mashup applications.

How does Microsoft SQL Server Data Services differ from traditional on premise relational SQL Server Database?
SQL Server Data Services is a storage and query processing utility providing mega scale, high availability, reliability, and geo-distributed data services in the Cloud. Customers use the service on-demand, with no up-front cost. It eliminates the initial investment in hardware and software and the on-going cost for storage administration, scale maintenance. Developers and Service providers can quickly run their on-demand applications with minimal infrastructure cost.

What can I do with SQL Server Data Services?
Customers can use SQL Server Data Services to store virtually any amount of data in the Cloud. They can query and modify data as required by the specific business scenarios. SQL Server Data Services support standards-based REST and SOAP interfaces designed to work with any Internet-development toolkit. The primary wire format is XML. Developers and service providers can quickly run on-demand applications with ease. The data has flexible schema which can be modified dynamically by the application. The data is provided with high availability and reliability virtually anywhere, anytime.

In SQL Server 2008 The CONVERT function is enhanced to allow conversions between binary and character hexadecimal values

SQL Server 2008 CTP 6 has enhanced the convert function when you do conversion between binary and character hexadecimal values
There are 3 styles:
Style 0 works the same as on 2005 it converts binary to varchar, if you have 0x64656E6973 then you will get 'denis'
Style 1 converts binary to varchar but the values stay the same, if you have 0x64656E6973 you will get '0x64656E6973'
Style 2 strips the 0x but leaves the rest of the values, if you have 0x64656E6973 you will get '64656E6973'

Try it out

When you run this

SELECT CONVERT(varbinary(5),'denis')

The output will be this 0x64656E6973. Now we can use that in the select statements below

SELECT CONVERT(varchar(18), 0x64656E6973, 0) AS 'Style 0' --denis
SELECT CONVERT(varchar(18), 0x64656E6973, 1) AS 'Style 1' --0x64656E6973
SELECT CONVERT(varchar(18), 0x64656E6973, 2) AS 'Style 2' --64656E6973

When you run the code above on SQL Server 2005 all 3 select statements return 'denis'

It is all in Books On Line for CTP 6, it would have been nice if they also included the sys.dm_tran_commit_table dmv or the sys.dm_exec_trigger_stats dmv. I have no clue what the sys.dm_tran_commit_table dmv is supposed to do :-(

46 New Dynamic Management Views In SQL Server 2008 CTP6

Remember the 33 new DMVs in SQL Server 2008 post? I was just poking around in SQL Server 2008  CTP6 and wanted to know if there were any new Dynamic Management Views since CTP5. There are 13 new DMVs in CTP6 and there are a total of 45 new Dynamic Management Views compared to SQL server 2005. The list of them is below, I think their names make clear what the dmv is supposed to do (or at least I think I know)

If Airplanes Were Made By Using Scrum/Agile

So I have been doing Scrum for a while now, I came across this video and thought it was hilarious. When you do Scrum you develop by using sprints, a sprint is usually between 2 and 4 weeks and at the end of the sprint you should have something working that you can show to the client/business unit

Watch the video



If someone is interested in a high level post about Scrum then leave a comment and I will post something next week

SQL Server 2008: When Was The Server Last Started?

SQL Server 2008 has an additional column in the sys.dm_os_sys_info Dynamic Management View. The name of the column is sqlserver_start_time and it will be the time SQL Server was last restarted

SELECT sqlserver_start_time FROM sys.dm_os_sys_info

Review of Inside Microsoft SQL Server 2005 Query Tuning and Optimization

SQL performance tuning is probably one of those things you can do to really make a HUGE difference in performance. Let’s put this in perspective: take a typical application, if you can improve the performance by 100% then you really made a huge improvement. You can improve a SQL query by 1000% with 2 lines of code (sometimes all you have to do is take away a % sign). If you can make a query sargable so that the optimizer can do an index seek instead of an index scan your query might go from 12 seconds to 200 milliseconds. Now try doing that in an application, even if you change all the string concatenation to use a stringbuilder instead of creating new strings all the time you will not get such a drastic performance improvement. I am sure you get the point by now, let’s talk about the book.

Inside Microsoft SQL Server 2005: Query Tuning and Optimization is part 4 of the Inside Microsoft SQL Server 2005 series, it is written by Kalen Delaney and five other authors. There are 6 chapters in this book

1 A Performance Troubleshooting Methodology

This chapter explains some typical things that affect performance and also gives a troubleshooting overview


2 Tracing and Profiling

This chapter explains how to use the profiler and how to analyze traces. SQL Server’s built-in traces are also covered


3 Query Execution

This chapter gives a query processing and execution overview. It explains how to read plans and goes into a lot of detail about analyzing plans


4 Troubleshooting Query Performance

This chapter explains how to detect problems in plans, how to improve queries and some best practices


5 Plan Caching and Recompilation

This chapter goes into detail about plan caching and recompilation and how to troubleshoot plan cache issues


6 Concurrency Problems

The final chapter deals with concurrency (locking, blocking and deadlocking)



This is an excellent book for an intermediate/advanced developer. There is so much new stuff in SQL Server 2005 compared to 2000 to help you with tuning queries that you probably want to read each chapter several times. The Dynamic Management Views are a big help and this book shows you how to use them. Some other cool stuff in this book is the discussion of internal tables, undocumented DBCC commands and undocumented trace flags to discover information which could help you determine much faster what the cause of a performance problem might be.
Some pages are packed with so much information that you need to pause for a second and process all that info (I have read some pages two to three times in a row). You will also find out that there are more joins besides left, full and outer. Page 137 for example has a nice table with the three Physical Join Operators: Nested Loop Join, Hash Join and Merge Join. This table lists the characteristics for each of these joins.

If you are an intermediate to advanced developer then I highly recommend this book. I have interviewed Kalen a while back about this book and you can find that interview here
