ITAD 2007 - Opole

Thu, 13 Dec 2007 21:36:36 GMT

I have just come back from Opole. I have lecture today there. I am really impressed how the organized the conference. Also attendees were great :) They asked me many questions. I have met some guys from Microsoft (B.Zass, M.Kedziora) and also collegues from LGBS (M.Wojtaszek, R.Jendrusz).Today attendance was 40+.

Great :)

Old lectures - Warsaw, May 2005

Wed, 12 Dec 2007 21:51:47 GMT

I have found my old lectures in Warsaw

Let's read :)

http://mimas.ceti.pl/tarpit/archiwum/1115725723

Jeżeli faktycznie jest jedną z najciekawszych, to chyba nie najlepiej świadczy to o kondycji informatyki polskiej. Widzę tylko kilka jasnych punktów na bezkresnej przestrzeni zacofania...

pudła

Nie da się ukryć, że nie obyło się bez kilku ewidentnych gniotów, np.:

Michał Niwicki (Aurox) w wielu infantylnych słowach pokazał, że Aurox potrafi obsługiwać BlueConnect,
Krzysztof Surowiec (Uniwersytet Warszawski) w wielu kompromitujących słowach (typu „nie da się zrobić strony dobrze wyglądającej na PC bez użycia tabel, a tymczasem na stronach przeznaczonych dla PDA lepiej tabelek nie używać..”) pokazał, że na współczesnym WWW nie zna się za grosz.

trafione

Jednak na konferencji znalazło się również kilka autentycznie ciekawych prezentacji. W tym najbardziej interesujące dla mnie:

Damian Widera przedstawił rozwiązanie Logotec Mobile@Connector — webaplikacja dla PocketPC wyklikana z kreatorów niczym program w MS Access, ;-)
Marek Jarecki z SKK opowiedział o rozwiązaniach opartych na urządzeniach Intermeca i oprogramowaniu myAVIS — IMHO prawdziwy sens tej całej branży.

uogólnione

A przy okazji poczyniłem dalsze ciekawe obserwacje na temat „sens i przyszłość PDA”:

PDA znikną, ponieważ zastąpią je smartfony — są mniejsze, lżejsze i wygodniejsze,
PDA znikną, ponieważ zastąpią je notebooki — nie są wcale tak dużo większe ani cięższe,
PDA nie znikną, ponieważ są najbardziej wygodne, łatwe oraz eleganckie i to nie tylko w zastosowaniach heavy-duty.

Powyższe trzy opinie spotykam już od jakiegoś czasu i chociaż każda z nich jest daleka od prawdy, to wszystkie trzy razem dosyć dokładnie opisują aktualny stan rozważań na ten temat. ;-)

W sumie jednak warto było...

Enterprise Data Platform: Data Collection and Performance Warehouse for Relational Engine

Wed, 12 Dec 2007 17:21:07 GMT

Hello

Again about Katmai. Today I have started looking at EDP. Especially- performance data collections are really extremelly important for DBA's but also a little complicated.. Iti is only my first look. Pawel Potasinski is going to write an article about this. It will be available on January 2008.

details:(https://connect.microsoft.com/SQLServer/content/content.aspx?ContentID=6962)

Data Collection and Performance Warehouse for Relational Engine

Performance tuning and troubleshooting are time-consuming tasks for the administrator. To provide actionable performance insights to administrators, SQL Server 2008 delivers more extensive performance data collection, a new centralized data repository for storing performance data and new tools for reporting and monitoring

Dynamic Development:Registered Servers Enhancements

Tue, 11 Dec 2007 22:24:31 GMT

Let's have a closer look to the another new feature.

(https://connect.microsoft.com/SQLServer/content/content.aspx?ContentID=6965)

Registered Servers Enhancements

Enhancements to the Registered Servers tool window in Management Studio include running T-SQL queries and policies against groups of servers and the ability to share a common, centrally stored, server topology (Database Engine only).

Community

Tue, 11 Dec 2007 22:21:24 GMT

Hello. Today I have really great news - Pawel Potasinski introduced Marcin Guzowski from Lublin and me to take part in a program which is called Heroes Happen Here. This is a program dedicated to the community leaders and will prepare us to the SQL Server 2008 launch!!!
I really would like to take part in it!

More details here:

Great thaks Pawel for this recognition

Dynamic Development: Service Broker

Fri, 07 Dec 2007 22:51:51 GMT

Hello , I'm back again

Let's have a closer look to the next feature that you can see in CTP 5.

More details here: https://connect.microsoft.com/SQLServer/content/content.aspx?ContentID=6963

Service Broker Enhancements

Getting the data to the right place at the right time is important. Service Broker Conversation Priority in SQL Server 2008 gives you greater control over the system by making it easy to configure priority rules so that the most important data is sent first and processed first. In addition, the new Service Broker Diagnostic Utility, ssbdiagnose, analyzes the configuration between two Service Broker services and reports back both the problems and their solutions.

ITAD - 4.12

Wed, 05 Dec 2007 12:35:49 GMT

Hello

I have just come back from first ITAD lectures.

The attendance was about 120 people, notes 4.37/5 , so it was not so bad :)

There were mainly students and the would like to come to ezU :)

Next week I go to Opole to my last lectures this year

Dynamic development: DMF Enhacements

Thu, 29 Nov 2007 00:50:07 GMT

Today I start another group on new features that are called Dynamic Develoment. The first one I would like to tell is Declarative Management Framework

(https://connect.microsoft.com/SQLServer/content/content.aspx?ContentID=6973). I am writing a quite interesting article about this and hopefully it will be ready next week and available on Polish TechNet site.

I would like to point out that DMF is one of the greatest new features that s been introduced to SQL Server 2008.

Lets look what's new about DMF - according to Microsoft:

Declarative Management Framework (DMF) Enhancements

Enhancements to DMF include more expressive conditions (including support for common functions, T-SQL, and WMI queries), more robust target set filtering, custom messages for policies, and the inclusion of best practice policies.

Pervasive Insight: Integration Services

Tue, 27 Nov 2007 13:24:57 GMT

Hello

Today let's have a look at the last enhacement CTP5 has brought.

This is very important feature as almost everybody uses SSIS in the every day DBA-life.

Go to the site (https://connect.microsoft.com/SQLServer/content/content.aspx?ContentID=7005) for details

Integration Services - Lookup Enhancements

The need to perform lookups is one of the most common extraction, transformation, and loading (ETL) operations. This is especially prevalent in data warehousing where fact records must use lookups to transform business keys to their corresponding surrogates. SSIS increases the performance of lookups to support the largest tables.

Pervasive Insight: Reporting Services Enhacements

Mon, 26 Nov 2007 21:22:31 GMT

Hello - today I am going to continue with new, cool features added in CTP5. Lets look what Microsoft has for us in Reporting Services. All the content you can also find there: https://connect.microsoft.com/SQLServer/content/content.aspx?ContentID=7004

Reporting Services Enhancements

· Robust Report Server Platform: Reports can easily be delivered throughout the organization with simplified deployment and configuration. This enables users to easily create and share reports of any size and complexity.

· Scale Engine and Robust Server Fit and Finish: A reengineered memory management and scalability infrastructure lays a solid foundation of scalability capability to enterprise customers.

My first webcast for Microsoft

Sun, 25 Nov 2007 01:25:00 GMT

I have just found Microsoft published my webcast about creating a database using SSMS. It is not a big thing for most of us but there are still many newbies and I would like to help them to start working with SQL Server.

The webcast is in polish.

Quite interesting article on Technet sites

Sun, 25 Nov 2007 00:57:33 GMT

Hello folks

I have been quite busy last time so I have not found this article on time. But - now I have to tell you - go to TechNet and read it immediatelly. Pawel Weichbroth did a great job and publish his experience with managing and administering RAID volumes. This is a must for all DBA's. I know - we all know this well , but sometimes is good to know someone wrote a comprehensive scrub:

Pervasive insight: Analysis Services Enhacements

Sat, 24 Nov 2007 21:20:28 GMT

Hello folks. Again - what's new in the CTP5. Today lets look athe the AS. I have read much about this on the official site (https://connect.microsoft.com/SQLServer/content/content.aspx?ContentID=7003)

Analysis Services Enhancements

MOLAP Performance (FITS): New MOLAP-enabled write-back capabilities in SQL Server 2008 Analysis Services remove the need to query ROLAP partitions. This provides users with enhanced writeback scenarios from within analytical applications without sacrificing the traditional OLAP performance.

Resource Monitoring: This concept is similar to DMV found in the relational engine. Analysis Services DMV addresses immediate needs of DBAs to get answers to the questions like: Who is connected to my server? What are the active sessions and what commands/queries they are running? What CPU consumed by particular query/command? What are the objects being referenced by particular command?

MDX Query Optimizer - Block Computation: Block computations provide a significant improvement in processing performance, enabling users to increase the depth of their hierarchies and complexity of the computations.

Aggregation Design: SQL Server 2008 drives broader analysis with enhanced analytical capabilities and with more complex computations and aggregations. The AS Aggregation Design improvement exposes Aggregation Design objects in SQL Server BI Dev Studio and SQL Server Management Studio and provides tools for users to better work with these aggregation designs. In addition, an advanced view in the new Aggregation Design tab of the cube editor provides the ability for an advanced user to view and manually edit individual aggregations within an aggregation design.

Analysis Services Cube Design: New cube design tools help users streamline the development of the analysis infrastructure, enabling them to build solutions for optimized performance. The AS Cube Design improvement introduces a new Cube Wizard which helps users create better cubes in fewer steps. The new wizard focuses on having the user answer a few questions to create leaner cubes that better targets their needs. It also unblocks the previously difficult scenarios of creating a cube a cube based on a single, de-normalized table and creating a cube containing only linked dimensions.

Pervasive insight: Partition - aligned indexed views

Thu, 22 Nov 2007 21:56:03 GMT

There are several improvement accordinpervasive insight in SQL Server 2008.

Detailed infromation is available here: http://www.microsoft.com/sql/2008/bi/index.html

This is a show where you can find any important information in high level overview.

Partition - aligned indexed views

Partition-aligned indexed views allow you to create and manage summary aggregates in your relational Data Warehouse more efficiently, and use them in scenarios where you couldn’t effectively use them before, improving query performance. This is a significant improvement over SQL Server 2005, where you must drop any indexed views defined on a partitioned table before using the ALTER TABLE SWITCH operation to switch a partition in or out of it.

New articles on the TechNet sites - Marcin Guzowski

Wed, 21 Nov 2007 14:28:24 GMT

A firend of mine - Marcin Guzowski - has just published a veri interested article on TechNet site.

On this article he explains the log file in details.IMO every DBA should know what is going on with the file, how important it is, why having more than one file gives you nothing...

You can find the article there:

Article about Change Data Capture (CDC) - the new feature from SQL Server 2008

Thu, 08 Nov 2007 22:20:35 GMT

Hello folks

My article about CDC has just been submitted in Polish TechNet

Follow that link: http://www.microsoft.com/poland/technet/article/art0088_01.mspx

to read it. Please send me any feedback and comments you have

I really appreciate this

New features in Katmai, but not the big ones

Sun, 04 Nov 2007 21:44:44 GMT

Hello

It's me again. Today two new cool features, but not that type as table variable:

a) quick variable initialization

b) multirow insert

a) DECLARE @variable2008 int=5
that's all

INSERT INTO someTable
VALUES(100,101,102),(110,111,112),(121,122,123)

that's all

What can I say - it is maybe not a big thing if you look at this. But in my opinion - this is the right step that Micrrosoft did as such small things really helps us in everyday life.

The greatest features added to SQL Server 2008 (so far) - Table variable

Fri, 02 Nov 2007 11:03:44 GMT

Table variable parameters

With SQL Server 2005,XML variables can be passed into stpored procedures and parsed with XQuery.The XML variable, as you probably know, can hold a table. In SQL Server 2008 there is possible to pass a table into a stored procedure directly:

use AdventureWorks
go

IF TYPE_ID('Person') IS NOT NULL
DROP TYPE Person
GO

CREATE TYPE Person AS TABLE
(
name varchar(20)
,surname varchar(20)
,BirthDate int
)
GO

--create a stored procedure to test if a table can be passed as a parameter
IF OBJECT_ID ('Test2008') IS NOT NULL
DROP PROC Test2008
GO
CREATE PROCEDURE Test2008
(
@person_instance Person READONLY --cannot be modified
)
AS BEGIN
SELECT * FROM @person_instance
END
GO

--declare a table variable
DECLARE @people as Person

--insert some data
INSERT INTO @people
VALUES ('Piotr','Nowak',1999),('Marek','Wolski',1988)

--run the stored procedure
EXEC Test2008 @people

How it works now, using SQL Server 2005:

first - a stored procedure that accepts an XML parameter

IF OBJECT_ID ('Test2005') IS NOT NULL
DROP PROC Test2005
GO

CREATE PROCEDURE Test2005
(
@personXML XML
)
AS BEGIN
SELECT C.value('@name','varchar(20)') as ImieXML
,C.value('@surname','varchar(20)') as NazwiskoXML
,C.value('@BirthDate','int') as RokUrodzeniaXML
FROM @personXML.nodes('/*') T(C)
END
GO

declaring an xml variable

DECLARE @xmlOsoba XML

put some data to the XML:
SET @xmlOsoba =(
SELECT name, surname,BirtDate FROM aTable AS L
FOR XML AUTO)

EXEC Test2005 @xmlOsoba

Well, look at the code for SQL 2008, escecially at the stored procedure body. It is easier to manipulate tables that do magic on xml....
