BI and General Management

 

This article is the first of a total of three that we are going to publish from LITEBI, each one will be part of a Whitepaper focused on the effects and contributions of Business Intelligence to the company from the point of view of the CEO. 

 

What is Business Intelligence?

Wikipedia gives us the following definition on this concept:
“Computer-based techniques used in identifying, extracting, and analyzing business data, such as sales revenue by products and/or departments, or by associated costs and incomes”

In other words, software tools that enable that all the information of a company (sales, purchases, financial information, production, marketing, etc.) “flows” in an organized way through the business, reaching the right person, at the right time. To this, in LITEBI we would also note that achieving Intelligence needs full-featured and integrated tools to manage and optimize the performance of the company as a whole and to align it with the business strategy.

A tool with all these characteristics makes things easier for those in charge of the decision making in each department: a CFO, a Sales Manager, a CEO or a Controller.

Documentación de IBM Cognos BIIn a Linkedin debate members have proposed a list of references and useful links about Cognos BI, as well as forums, blogs and resources. I've organized a bit the proposals. I hope you find it useful..

How to connect to a remote MySQL database

 

 

MySQL has some special features when making a connection from a remote client that if we do not know can complicate access to a MySQL database from a different machine that hosts the database.

With other databases such as Oracle or SQL Server, once that no firewall or anything like that prevents us from the client machine access to the server, using normally data acces from a database user we can 'enter'.

With MySQL, although access to the port, usually 3306, is open, the database can be configured to shut out external connections, and the result is the same as if the port was closed by a firewall:

 

telnet mysql.dataprix.es 3306
Trying 188.166.233.199...
telnet: connect to address 188.166.233.199: Connection refused
telnet: Unable to connect to remote host

 

If you get this result should consult the file /etc/my.cnf, and checking for bind-address variable or skip-networking.

If skip-networking is and is not discussed, edit the file and delete it, or make a comment to have no effect and allow external connections:

Learning NoSQL

 

The emergence of twitter, facebook, Groupon, amazon, etc ... is becoming increasingly popular new forms of large data storage and fast access to them. The terms NoSQL , Big Data , Hadoop ... are rapidly becoming popular.

Not long ago we talked about it:

 

- Comparison of NoSQL Databases ( Cassandra , MongoDB , CouchDB , Redis , Riak and HBase ) 
- Infographics, the potential for big data . 
- Pentaho also is accelerating much its integration with Big Data.

 

Today we give you some more detailed presentations, where we can research:  

Statistical Data Warehouse - European Central Bank

 

European Central Bank StatisticsI found very interesting the initiative of the European Central Bank, to provide a statistical service on-line in the so-called Statistical Data Warehouse (SDW).

This Data Warehouse is aimed at a broad spectrum of users (financial analysts, journalists, businesses, economists, researchers, etc. ..). Provides macroeconomic data on-line in the euro zone: inflation, exchange rates, labor costs, unemployment, productivity, public deficit, public debt, payments balance, international investment position, sociodemographic data, tax information, etc...

Aspects to evaluate the selection of an ETL tool

 

Addressing a business intelligence project is important to proper assessment of the ETL tool that we will use. The tool based on which we will implement our procurement processes of the Datamart, Datawarehouse or storage structure based on which further exploit the data. It is a cornerstone for the design, construction and subsequent evolution of our BI system. We will analyze technical issues only, without entering into the economic aspects or otherwise (licenses, agreements, technical support, tool changes, etc. ..) . Note that the ETL processes, are closely linked to the processes of data profiling and data quality, here we will not consider.

Make charts quickly with SAS (SAS module / BASE)

 

We continuously meet with the need for rankings, get the top ten or top N of our customers get by product, geographic region, etc ...

Obviously there are thousands of ways and tools to get it. Enclosed below is a quick way to do if you are member of SAS, specifically SAS / BASE and you have already in SAS data set and want to avoid having to pass these data to other modules or reporting tools.

Oracle BI Publisher

 

We show a summary of capabilities of this tool integrated in the Oracle BI suite including the features included in version 11g.

Real Time Data Integration - CDC

 

There is an ever greater need in the Business Intelligence environment to have the information in the shortest time possible, data generation cycles getting shorter and updating of data in near real time. There is talk of 'Operational Business Intelligence (OBI)' and 'Real Time Decision Support'.

It is critical to reaching operational data analytic environments in shortest possible time. There is a need for a 'Real Time Data Integration'.

In the optimization of these data integration processes, we must consider both the usual source data (ERP's, CRM's, operating systems, databases, flat files, Excel, XML, etc. ..) and other from more immediate nature such as messaging queues and on-line information accessed via Web services or RSS.
