Some information systems have exceeded the boundaries of the department and his knowledge has spread to all areas of the company. As the technologies are becoming easier to use and accessible for all business casuistry, his knowledge extends and extends beyond the field of "understood" by the experts, to be known by every company profiles. Concepts such as CRM, ERP, etc., Not long ago in companies known only to the department and the department involved (Marketing and Sales for CRM, ERP Operations, Human Resources for the intranet, etc.).. Concepts today are managed and understood by anyone in the business world.

As for Business Intelligence, I believe that unfortunately is still preserve of experts and technologists. Today it is very common to find a business decision makers are unclear about the functions, spheres of influence, potential and business benefits of a Business Intelligence system. The BI is still known by a few, there has been democratized, it has jumped the hurdles of technology to be part of each and every one of the departments of companies. In my opinion there are several reasons for this.

Good.
I finally finished reading the book Pentaho Solutions, who kindly have sent me Roland Bouman (co-author of the book) and Wiley.

On that occasion will realize different reviews from different points of view, as I did with Pentaho Reporting. Here are the reviews:

1) Overview :  It is a very easy book to read and handled very well the theoretical and practical.

As the concepts are giving more complex and heavy, is always accompanied with an example, graphic or exercise.

This book is really very useful and indispensable reading both for those who are just beginning to work with Pentaho, and for that we have some time.

"The goal of Business Intelligence is to provide the information they need, when you need it and in a form appropriate to people who have to make decisions."

The aim of this paper is to support the Business Intelligence or BI should be, of all business software tools (including CRM, ERP, or BI himself), that is closest to the role of management, specifically the Executive Officer.

Since the computer revolution and the explosion of Internet, information is becoming more and more importance. Everything is or will soon be digitized, the amount of information available each year is multiplied and the activity of our business is computerized in most respects.

Studies tell us that the information maintained by companies is doubling every two years and that 80% of decisions are made with only 10% of the available information.

And all of this information is power! Is necessary, vital, to compete. 

In MySQL, when you delete records from a table, space is reallocated automatically. It is as empty space and forming new attachments will advantage.

The problem is that if a table perform many DELETE operations, the physical space of the table will become increasingly fragmented and the performance is reduced.

In the MyISAM and InnoDB, OPTIMIZE TABLE command available to perform an optimization on any table that, among other things, performs an automatic defragmentation of the table.

It is highly recommended to use this command regularly especially on tables that are more statements of disposal of records.

As a precaution, keep in mind that during implementation, of course, the table is blocked. You have to remember when you are going to use with large tables and busy.

Supersimples The syntax is:

OPTIMIZE [NO_WRITE_TO_BINLOG | LOCAL] TABLE mi_tabla1 [, mi_tabla2] ...;

To make a fragmented table optimization can be selected to have free space, probably as a result of DELETE statements:

For those database administrators who have to deal with such a Dynamics Ax 2009 and his henchmen (developers, consultants, etc. )  I leave here a couple of things you should know (or I should say) when we join ax2009 and sql server 2008. Sometimes you can point to the database as a source of the problem but not always. Some requirements to consider for installing Ax2009 are that the user you want access to the system should be user and DOMAIN in sql server role must be a member of securityadmin dbcreator and to create the new database from Ax installer. Once installed (or during the installation process) the problem with the database that we can find include: 

In a previous blog entry ( OpenSource Databases. Why did we choose for our project Mysql?), talked about the Open Source databases such as interesting and reliable option for the development of business intelligence projects. We saw some different products and compare between them.

But there are other alternatives (with limitations in most cases) that allow us to start working with "big" of a free. Express versions are called. Versions are designed for small systems, for development work or training, for prototyping or evaluation, that allow us to "initiation" with the great managers of relational databases. In most cases, the product is offered fully functional, but with limitations (the maximum size of the database, use Ram memory or processors of the machine, etc). There may also be features that are not active in these versions (such as partitioning version  of Oracle Express).  I leave the link to the manufacturers' web sites where you can download these versions:

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 expected, the first BI tools adapted to the new iPad of Apple are appearing. Nothing like a dashboard application to exploit the Multitouch screen possibilities of this device.

Prelytis is the company that has developed Prelytis LiveDashBoard, the first Business Intelligence software compatible with the new Apple Tablet. This is a dashboarding tool, and 2.0 oriented, with collaborative features, and remarkable for their efforts in terms of adaptation to mobile devices.
