A few minutes are up to publish the stable versions of Pentaho BI Server 3.5.2.
You can download it at: https://sourceforge.net/projects/pentaho/files/
I have not reviewed this version, but I am doing beta testing before and have found no major changes in the UI, just some updates of bookstores, but not widen too much.
Whenever I get more information, I have the relevant comments.
Greetings
Cassandra is an open source database distributed, is one of the noteworthy projects of the Apache Software Foundation and appears to be hitting hard. By being distributed enables high availability, fault tolerance and, above all, a highly scalable without loss of performance.
And were using companies that handle large amounts of data such as Rackspace, Digg, or Facebook, and the list is expanding.
The latest news, coming from a blog interview with Ryan King MyNoSQL is that Twitter is considering migrating their MySQL server clusters Cassandra DB.
This is a product presentation, which can be found in the same web Cassandra Project
Slowly changing dimensions or SCD (Slowly Changing Dimensions) are dimensions in which their data tend to change over time, either occasional or constant, or involving a single record or the entire table. When these changes occur, you can opt to follow one of these two great options:
An Oracle database in Standby is an exact copy of an operational database on a remote server, used as a backup, and copy for reference, disaster recovery, etc..
A database in the Standby mode is more than a normal backup because it can be put into production disaster in less time than if we had to restore a copy (either from a simple rman or export).Restore a copy from file takes time, and during this period the system is unavailable. With an additional database in standby mode there is nothing (or almost nothing to restore) in case of disaster. Within minutes, allowing the change is continuity of service. It offers the performance advantages of a cluster or safety of the mirror but the ratio of costs versus benefits and leave time seems right to me.
From a global perspective:
To get an idea of the volume of business that moves Google infografia nothing better than that prepared in pingdom, which collected on the same graph one timeline with key milestones of the company, impressive numbers on the form, increase in revenues , figures on company employees, and the most significant data on other successful products such as Android, YouTube, Blogger, Gmail, Chrome, Orkut or Analytics.
A good source of inspiration for anyone eager to create a scorecard where we could see these evolve dynamically as so well chosen indicators.
Surely more than one person has clicked on an indicator in the chart to see if anything more;)..
It may happen that after you install or configure a new Oracle database we realize that the character set chosen during installation is not correct. What we may happen in cases like this is to delete the database and reconfigure it or worse ...But you do not. We can change the character set stopping the database, looking up strictly by changing the settings and restart the database. Howto:
- First we connect to the database
$ sqlplus sys/pwd@prod as sysdba
- We stop the database
SQL>SHUTDOWN IMMEDIATE;
- We raise strictly *
SQL>STARTUP MOUNT;
SQL>ALTER SYSTEM ENABLE RESTRICTED SESSION;
SQL>ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
SQL>ALTER DATABASE OPEN;
- Change the character map
SQL>ALTER DATABASE CHARACTER SET <new characters map>;
- Restart the database and yata
In Oracle databases there is a table that allows to list all the tables in the database (table 'dba_tables') and we can use this 'dba_tables' to create maintenance scripts dynamically. In SQL Server we can create also scripts of tables maintenace by querying the table [dataBase].dbo.sysobjects.
In the example below we use a T-SQL script to update statistics for all tables in a SQL Server database by querying dynamically the data dictionary (using the table dbo.sysobjects). This T-SQL code can be encapsulated in a stored procedure or in a job to be executed by the SQL Server Agent to automatically keep statistics updated on all tables of the dbo scheme in a SQL Server database.
Hello People
Following a series of needs I have decided to develop for the group eglu and, of course, to all of you, a plugin that allows you to use jQuery FlexiGrid since Pentaho-CDF.
Not if you permit to happen, my especially if they need a list with a number of features such as filtering, sorting, paging, sorting, selection of visible columns, resize, etc.. Without doubt, this is what jQuery provides FlexiGrid 2.0. The theme is to make it work in Pentaho is somewhat cumbersome, this was my trigger. Without further ado I attached a video showing the functionality of the plugin. In a few days annexed to the plugin, source, demos and documentation so they can try and give me feedback.
Today we have consulted our position in the Alexia ranking, and we have been pleasantly surprised to find that this March we are located at or even above doorways as TDWI o BeyeNETWORK are undisputed global benchmark .
As many have noticed, we changed Dataprix logo.
Although the symbol of the head with the database during the previous logo reflected fairly well the spirit of Dataprix, and the relationship between data and knowledge, we believe it necessary to create a logo more 'professional', which will be the basis corporate image Dataprix.
Our primary corporate color is still blue, so the change on the web has not noticed too. We have changed the symbol for a 3D database, and D-shaped, to keep referring to the data, and lose the reference to knowledge that gave us the figure of a blue head, but you can not have everything in life ;).
In addition, we've heard from somewhere that may be better to simplify the meaning of the symbol to convey a clearer picture. For people not as technological areas, which need not recognize the symbol of a database could also be difficult to identify. On occasion I have come to discuss that on seeing the logo Dataprix seemed he might have something to do with a headache, or Bayer aspirin ..
