En 2012, les principaux systèmes de gestion de bases de données relationnelles (SGBDR) sur le marché sont propriétaires. Nous parlons régulièrement d'Oracle Database, MySQL, Microsoft SQL Server. En dehors de ces solutions commerciales, il existe un SGDBR open-source largement utilisé: il s'agit de PostgreSQL et il est l'objet de cet article.

In my previous article, I announced the first fix for SQL Server 2012.

One week later, the first cumulative update is available on the Microsoft website.

This is just a little blog posting to announce that the first fix for SQL Server 2012 came out last week during Easter Break.

Since the commercial version of SQL Server 2012 is due to be released in April, a little posting about the changed licensing costs seems appropriate.

The so called Release to Manufacturing (RTM) version of SQL Server 2012 now is available.

Following my article about Windows 8, Microsoft today released the customer preview. This is just a small posting to announce this fresh news!

I have decided to take some time in this cold month of February to continue this small series. This time, I'm going to speak about Reporting Services (SSRS) and some new features. Like my other article "SQL Server 2012: New features on Integration Services (SSIS)", this article presents a summary of new features and enhancements for SQL 2012 Reporting Services.

Like other SQL server 2012 products, Integration Services has a lot of new features and enhancements. I am presenting a summary of these new "goodies" (from CTP1 to RC0), which can be powerful for DBAs and developers.

Since the third CTP version of SQL Server 2012 (codename Denali), there are some new features available to provide an additional value like the for other Microsoft SQL Server versions. These are pooled in the so called 'Feature Pack' as well as in the 'Manageability Tool Kit'. Both are already available, but not in the final version. I have compiled all information in this blog to find it easily. All DBAs should know that Feature Pack exists, how to find it, and of course use it.

Since a few days, Microsoft® SQL Server® 2012 Express LocalDB Release Candidate 0 is online.

We were looking forward to it and it has finally arrived...

Since Friday, 18 November, Microsoft® SQL Server® 2012 Release Candidate 0 is online.

Today, Microsoft gives us his secrets of the next SQL Server version.

We have now arrived at the end of the largest Oracle OpenWorld ever. Around 45'000 people traveled to San Francisco to exchange on IT and especially Oracle technologies. It has been a great conference with a lot of interesting sessions and several announcements as every year: Enterprise Manager 12c, Exalytics and Oracle Public Cloud.

For my last post on OOW '11, I want to talk about the last session I attended. Who said that late sessions are usually less interesting? I personally was lucky enough to attend a great presentation held by Oak Table member Alex Gorbachev. Alex used ASM to demonstrate how hardware and software fault tolerance mechanisms, especially mirroring, are affected by different parameters such as MTBF.

This has been a long day. It started with gathering some news about Enterprise Manager 12c and finished with a huge concert on Treasure Island. However, the highlight of the day was clearly Larry Ellison's Keynote. Since this afternoon (pacific time), Oracle is officially offering a public cloud integrating an Oracle social network!

In my second blog posting about OpenWorld, I wrote about the Engineered Solutions portfolio that just got enhanced with Exalytics. Today I'm going to focus a bit more on Oracle Database Appliance and how this new box works. I had the chance to go to a session called "New! Database Appliance: secrets revealed", which provided more information on its architecture and functionality. After that I went to a highly interesting use case by Dell on the brand new Oracle Enterprise Manager 12c for Cloud computing. But first let's have a look at the Database Appliance secrets...

Oracle OpenWorld's day 2 is now over … with some rain… We had some interesting sessions such as Fusion Middleware, RMAN or NoSQL.

In this OOW 'Road Journal' post, I am going to focus on two of them, introducing a coming Data Center Management solution and giving an outlook on the Oracle Enterprise Linux roadmap.

So the first day of the Oracle OpenWorld 2011 is over. This introduction day was dedicated to Oracle Users, Oracle Partner Forums, and the Welcome Keynote. It already showed some interesting stuff and finished with a new announcement.

Finally after a 18 hours, door-to-door, journey I arrived at San Francisco for Oracle OpenWorld 2011. My trip started in Basel, with a stop in Paris and then an 11 hours flight to San Francisco. Even with the on-board movies these kind of flights are still quite boring, but the funny things is that I really thought I was flying with "Air Oracle"…

At dbi services, we have a few people passionate about diving. Let me take this opportunity to let you dive into the two databases lakes Oracle and SQL Server to see their similarities and differences. For this first level of diving (named ODD), we will not be going too deep for reasons of narcosis or databases toxicity. As always, we will start with a short briefing to present the environment and the different themes. Have a nice dive !

Souvent, je me suis aperçu que beaucoup de personnes se posaient des questions simples sur Microsoft SQL Server, comme par exemple : "Depuis quand existe SQL Server ?", "Quelles versions y a-t-il ?", "C'est quoi les services d'SQL Server" ?
C'est pour toutes ces questions que l'on se pose de temps en temps que je vous propose ce petit article sur le sujet.
