Open source data mining tools


Data mining is a necessary task for most Industrial Engineers and Operations Research analysts. Often times the analyst is forced to comb through a lot of data in order to gather information. There are many tools, often proprietary, to attack the piles of data. Some examples of great data mining tools include Excel or Access. Other more complicated tools include Microsfoft SQL Server or Oracle databases.

The Open Source community has been no stranger to developing tools for data mining. There are many free software equivalents for data mining for any analyst. Data can be mined in spreadsheets such as Openoffice Calc or KSpread. They can be compatible with windows files such as .xls for quick transfer from other data sources. These office suites are free to download on multiple operating systems.

Databases have been developed extensively in the open source community. Openoffice has an application similar to Access called Base. There are many free software database servers available for use including MySQL and PostgreSQL. There are numerous free software SQL clients including Knoda and GNOME-DB. PhpMyAdmin is a web-based MySQL client that can be setup with a webserver, such as Apache and interfaced with an internet browser.

There are also free software applications developed especially for data mining. These free software options include Weka and RapidMiner. These tools can be used as stand alone clients that can connect to any number of data souces, including proprietary ones.

My husband left me last year after 25 years of marriage (he turned 50). It has been the most difficult year of my life, but full of lessons about myself and what life and marriage are all about. I am passionate about marriage and i didn't give up on my husband. resides in USA, I entered online in search of advice on how i can amend my marriage while i was at work. I saw so many positive reviews and nice feed back about how a Doctor called______________Robinson.buckler@ yahoo. com has been wonderful with his work. I gave a shot to make contact with him via his Email and he assured me that my marriage will be peaceful and i believed in his words. 16 hours after he finished work, my husband came back home pleading and now, we are living peacefully again. Get in contact with him if you need any help. he is the real deal WE’RE BACK!!!!!!!!!!!!!!!!!!!!!
