Question

I am to research about Business Intelligence, and I searched for these:

Oracle BI
Microsoft Power BI
SQL Server Reporting Services

My problems are:

Oracle BI downloadable files are too big.
Power BI is only available online (you have to sign up for Office 365)

So my last and easiest way is the SSRS. Should this be enough for me to understand BI? I have read a bit about BI and it says there that I will need a data warehouse and some other components that make up a BI.

Requirements:

Free (or at least trial version)
Less than 1GB to download
Usable offline (not a webapp)
User-friendly for people who are not BI specialists yet
Feature discoverability: one can learn by using the software
Covering at least ETL, analysis, reporting

Explanation / Answer

Pentaho (Community version) will suit your purpose perfectly.

Pentaho has separate software programs for each aspect of BI (ETL, cubes creation, drilling/MDX, reports, dashboards, automation, etc), making it easy to understand the various activities of Business Intelligence.

Each of the entities is Open Source. That means that not only it is free, but in addition you can read the source code if you really want to study it in deep. Open source means that no "magic" or "black box" will prevent you from understanding everything that is going on.

Lastly, the Pentaho community is much more open than other BI communities, which means that you will more easily find blogs, questions/answers, tutorials.

I learnt BI by myself just by exploring Pentaho.
Works on Linux/Mac/Windows.
