Dear Colleagues of the Database World!
I present to you a comprehensive introductory course in SQL Server
2014 BI. This course is presented in the Arabic language, and is
intended to introduce core concepts to Database Professionals that are
trying to acquire knowledge in SQL Server BI. The course is geared
towards those that aspire to become BI Developers, or those just
interesting in learning the basics of SQL Server BI. Since there is very
little material in Arabic, I decided to try to use my skills to bridge
the knowledge gap for my SQL Family that communicates in Arabic. I
hope you enjoy the classes and please feel free to share and leave
constructive feedback.
Thank you and good luck future SQL Server Professionals world wide!
Special thanks to my friends Mohamed Elsharkawy for his help and support with this production.
Finally the arrival of Part 3 of my SQL Snack Pack on Performance Tuning! The series is dedicated to help beginners understand how to start performance tuning with SQL Server. The first video was about performing a baseline using the PAL tool.I would highly recommend you review that video as well as my SQL Snack on Instant File Initialization. Also, if you missed part two from yesterday you can review it here.
If you are still interested in learning more about Performance tuning with SQL Server, I will be giving an hour long presentation with the PASS DBA Fundamentals Virtual Chapter on January 6, 2015 (11 am Central Time/Noon Eastern Time). For more information please visit http://dbafundamentals.sqlpass.org/ and join PASS for a great way to learn more about SQL Server.
Finally the arrival of Part 2 of my SQL Snack Pack on Performance Tuning! The series is dedicated to help beginners understand how to start performance tuning with SQL Server. The first video was about performing a baseline using the PAL tool.I would highly recommend you review that video as well as my SQL Snack on Instant File Initialization. This second video discusses the importance of properly sizing Data files, placement, and how the Proportional Fill-Algorithm works for data insertion. I’m hoping you get some last minute Performance tuning in before 2015 and so I will be posting the third video within the next 24 hours.
Welcome to Part 1 of my SQL Snack Pack on Performance Tuning! The series is dedicated to help beginners understand how to start performance tuning with SQL Server. This first video describes how to setup a baseline for your system using the PAL tools. It is essential to get a baseline before you start performance tuning so that you can determine how effective the efforts done in trying to tune your SQL Server have been. The PAL tools at first look a little intimidating but they are really very easy to use and extremely helpful for performance analysis. Enjoy and happy baselining!
A special thanks to Edgardo Valdez for showing me the how to use this tool.
Welcome back for part 3 of my SQL Snack Pack on Table Partitioning! If you have not watched the first two videos, I would highly encourage you to do so.
I hope you’re hungry for another SQL Snack! In fact, this will be one of a series of snacks (dare I call it a SQL Snack pack?). Table partitioning is a fantastic feature that is easy to learn and can significantly improve your OLTP and Data-warehouse environments. It can be a little intimidating because it is tricky to get started with, but once you get the basics down you’ll realize it’s pretty straight forward and a very useful feature to have. I will be providing the code and outline for each of the SQL Snacks related to table partitioning so that you have a chance to practice on your own. Happy partitioning!
Instant File Initialization (IFI) is an interesting topic with regards to how SQL Server works with storage. It is an easy feature to turn on and can improve the performance of your server; specifically with creation and growth of data files including TempDB rebuilds with SQL Server restarts. There is a slight security risk where a professional data thief could potentially recover bits of data that have not been over written since IFI was turned on, but the chances of that happening are slim. Plus, if they have physical access to the hard drives on your server, you will have bigger problems to fix.
So without further ado here is the next delicious SQL Snack for Instant File Initialization:

On July 10th 2013, I gave a presentation with the Professional Association for SQL Server (PASS) DBA Fundamentals Virtual Chapter. The topic was Indexing Fundamentals and there were some questions that we did not have time to answer. I have combined similar questions and given one answer to cover the specific topic.
Abstract:
Indexing is an integral part of SQL Performance and Architecture. In this presentation we will cover the basics of Clustered and Non-Clustered Index structure and function. Additionally, we will discuss the B-Tree structure, index density (fill factor), page splits, and performance considerations. Finally, there will be a brief discussion of index maintenance.
**This Session has been rescheduled for July 10th @ Noon EST (16:00 UTC)**
On July 10th 2013 @ Noon EST (16:00 UTC) I will be giving a presentation with the Professional Association for SQL Server (PASS) DBA Fundamentals Virtual Chapter. Entrance is free as always and details can be found at http://fundamentals.sqlpass.org.
Code, Slides, and other information about the presentation will be under the Presentations section of this site afterward. Hope to see you there!

Ever wanted to know the reason behind the Database color scheme in SQL Server Management Studio?
I have always wondered why all the Databases in management studio were Yellow (Online), Grey (Read-Only), Lighter Yellow with text next to it (something like Restoring), or Yellow with a Red Icon (Offline). Have you ever wondered why there aren’t any more useful colors like Red for when a Transaction Log is Full or Purple when your Statistics are Outdated. I have a theory on this that I have entitled “The Theory that you have to actually work to call yourself a DBA.”
For the past couple of months I have been working with Ben Weiss a Digital Marketing Strategist at Infusive Solutions (http://www.infusivesolutions.com/). Our partnership was based on a mutual understanding that there is much needed career growth and guidance among IT Professionals. Since my background is primarily with Database Management Systems I have been helping him with writing articles, guides, and even interview questions for top professionals in the field, all for the purpose of furthering the careers of IT professionals.
I received an email from a connection on LinkedIn seeking some advice for architecture on a new reporting system. Although I don’t know the gentleman personally, he is a SQL Server professional and I felt obliged to help out a fellow colleague in the field. The email is included below and my suggested solutions following it.
The SQL Server Parallel Data Warehouse and SQL Server Fast Track Data Warehouse are very high end builds of Microsoft’s SQL Server 2008R2 product; and SQL 2012 in the future. I’ve been intrigued by these products so I’ve started to learn about it. They have both been on the market for a while, but I’ve just recently been exposed to the technology and it has been exciting to learn more and more about it.
Module 2 talks about the PDW architecture. Module 4 talks about the Fast Track Datawarehouse; which is a product that sits between your custom build of SQL Server and the PDW. Of course all the other modules are useful, but just in case you wanted to take a quick dive into material related to the PDW you should go for Modules 2 and 4.
An interesting post by Gethyn Ellis about an issue he encountered using Availability Groups. Follow the link above to read more.
I run into an interesting issue with an Availability Group database recently. I was running a data load against a database in an Always On Availability group database in SQL Server 2012. The load was SSIS package migrating data from staging database when the package fell over with the following error
“The transaction log for database DBName is full due to ‘AVAILABILITY_REPLICA’”
CORRECTION: This is for CTP4 (Community Technology Preview) not RTM (Release to Manufacturing). Therefore, you cannot install this if you are running a full version of SQL Server 2012. Sorry for the confusion, the original article I read did not mention anything about it being for CTP.
A part of every DBA’s job is to justify all those disk space requests. The phrases “I just need it” or “Trust me this database is going to grow one terabyte this year” might not convince your boss.
Many people are under the impression that disk space is cheap since they base that notion off of the shell shocker they saw on NewEgg or the weekly circular from Best Buy. If you are using consumer SATA drives from retail outlets for your production databases please do the following:
1. Update your resume
2. Apply for jobs at least 1000 miles from your current location
3. Hope the next DBA that replaces you has more common sense
We’re in the times of SANs, iSCSI, SAS drives, SSD drives and RAID architecture! You should be forking out almost the cost of your server in disk space. Unless of course losing data is an option where you work.
Now that I’ve bored you or intrigued you (or something in between) I can get to my point. There is a wonderful tool that comes with SQL Server 2008 and later called the Management Data Warehouse (MDW) also known as the Data Collector.
I’m going to call the series on System Center for the SQL Server DBA complete with this one last post today. First, here is the full series to date … my apologies for the lack of post naming consistency!!
What I wanted to point you all to is an update to my methodology of using SQL Server 2012 business intelligence leveraging in-memory analytical models to provide very important insights into your SQL Server environment with System Center Operations Manager. The link is here to my blog on this on SQL Server Pro Magazine.
