I'm using mysql for my database needs and the total size is ~1.5 TB.
I'm looking for a Business intelligence tool which gives me an interface to fetch reports in any desired format to help decision making. The user shall be able to sum, sort, count, sum in various ways.
I don't know what shall I do about it.
In the past few days, I've read dozen of articles and watched many videos about Bigdata, hadoop, BIRT, Solr, Cassandra, mongodb, noSql and just everything that popped in search suggestions for my queries on BI but can't decide what's the right tool for me.
Is there a tool available to help me with my Data reporting and visualizing needs?
Did you read about Tableau (http://www.tableausoftware.com/)? Its a very nice data visualization tool (though not free but worth it) and can connect to various data sources (mysql, hive etc). Also it provides options to do all such operations you mentioned. It will be worth to evaluate it once.
It provides a 15 day free version. You can try out and see if it fits your needs.
Try Google Big Query, it should solve your issue

I'm coping MySQL databases to Red-Shift with the help of an ETL tool called Matillion, and I'm using the same tool to query the database. Most of the queries I've written are basic select queries with lots of joins, unions and sub-queries.
Since Red-Shift is specialized for analytical processing, I want to transform my basic queries into OLTP queries.
I'll be grateful if someone could point me a direction to learn how to write queries more OLTP way.
Thanks!
To clarify, Redshift is not an OLAP database (like HANA or SSAS), so you can't query Redshift in an OLAP way.
However, Redshift does of course support the full range of analytic functions, which are very much OLAP-like: http://docs.aws.amazon.com/redshift/latest/dg/c_Window_functions.html
Matillion supports that too, for example with the
Window Calculation Component
https://redshiftsupport.matillion.com/customer/portal/articles/1991935-window-calculation-component
You can also search for a Rank Component on the Matillion ETL for Amazon Redshift support portal.
Matillion also has documentation/videos on Data Quality Framework which goes through some of these.

is there good tool to analyse some csv-formatted data files. is there any easy to use open source thing to display data from csv-files? (please don't mention excel...). most important is an easy file import (or maybe folder read-out) mechanism.
I found D3 to be the best solution: http://d3js.org/
An excellent tool is Weka. It accepts data in csv as well as arff format. It is free and open source, can be used to visualize as well as to run inbuilt machine learning algorithms to gain more insights into the data.
The best thing is that it is extremely light weight and easy to use, you don't need anything except support for java.
Get it from here. Once started, it looks like :
Now go to Explorer, open file and you are done!
IBM's Many Eyes project is a free web-based collaborative tool that has lots of charts available.
Better, but expensive, are Spotfire and Tableau. Both are amazing commercial applications for this, and Spotfire especially is incredibly easy to use to explore lots of visualizations side-by-side. Both have a desktop version and an online web player (Spotfire demo gallery, Tableau demo gallery). They are both highly scalable, into the millions of rows. Both have free trials.

Is there any web service to analyze big data sets and plotting graphics like in Excel? I need something simple, efficient and with web GUI.
Google Fusion Table might be a candidate for your choice.
Google Docs also can be your choice, if you just want simple Excel-like graphics.
If you want to have more controll over the analysis (not just using Excel as a table editor), you can try analytic tools like BellaDati (https://service.belladati.com/login). It is still free for personal use.
Google Fusion Table is good for data mining but not analysis and createing charts. Bi software creates good summary charts/pivot tables etc. not scientific charts. What kind of data you want to analyse?
Peter
Web Pivot Table is this kind of tool you could give it a try. It can connect to CSV files or OLAP Cubes and do any pivot operations just like excel. It is web based and totally run inside browsers.
And it is pure javascript implementation which can be easily embedded into any web application as a component.
Here is demo and documents.

What is the best FREE solution to implement one ETL project in MySql?
I need to extract for analisys big amount of data, and put the results in other tables.
Regards,
Pedro
Pentaho Kettle (PDI) is open source and it has a community version here, which works quite good.
Talend also does an excellent job for ETL and ELT. You can take a look at this page on my website: http://www.hiregion.com/2010/01/data-loading-through-talend-etl-studio.html and related articles. I have also loaded hundreds of thousands of rows to millions through MySQL bulk loading (LOAD DATA INFILE syntax - dev.mysql.com/doc/refman/5.1/en/load-data.html ) and then doing some transformations in MySQL. You can do most of transformations before the load (ETL) or after load (ELT) or use hybrid technique.

I m looking at creative solutions for reporting, I have an app and now i need to create some reports from it.
I would be led to believe that the customer will be happy enough with excel reports, however what I want is that they have the freedom to create the reports themselves, without any help from development, so i need something simple yet powerful ( fun to work with would be a plus :) )
I use MS SQL Express.
Web or desktop deployment: it doesnt make any difference
Licensing costs Ideally none as its a very small operation
Open Source: preferred
Metadata modelling: none
Handle large amounts of data: not really, in the 100k records
large numbers of concurrent users: not really, 1 or 2 users
I remember I read about an csv solution somewhere but I cant remember if it came with a reporting engine of some sort
Thanks for your ideas
Allowing users to generate their own reports would be wonderful, but for anything beyond a simple report, this quickly require basic database skills. I've never seen a user-accessible report designer that users could actually design reports of any complexity with.
You're better off providing two things:
The most obvious reports with some filtering/sorting options. Common ways to do this are with Crystal for a desktop app or SQL Server Reporting Services for a web app.
The ability to export raw data to Excel. Office skills are far more common in most user groups than database skills. Your users will have a better chance of creating a report with an Excel chart than they will have of working through any report designer I've ever seen.
