Doubt

[MathAllims]

I am making this post to ask a few things about Power BI.

I am trying to use this tool and I have some doubts, could someone help me?

I would like to know approximately what size of data in megabytes is recommended to work.

I would also like to know, directly from you, what the true focus of Power BI is. During my study I felt that it does not do very well the part of Data Mining and I had doubts about its application. If it is not a tool focused on Data Mining, do you recommend some tool to use with it?

I am trying to create a report to view some information and I am also not able to make a function work, it responds with an error:

The expression references columns. Can not convert multiple columns to a scalar value

My focus would be to use Power BI seriously in my everyday life, but I'm beginning to wonder if it suits me.

I have worked with files quite successfully in the 400-500 MB range. I believe up to 1 GB is supported but you may want to start looking at doing live connections at that point. Now, remember that the source data may be significantly larger than that. Power BI tablular model does columnar compression and is really good at crunching up data.

Power BI is primarily intended to be a self-service reporting tool for business end users. I would not classify it as a heavy duty data mining/data wrangling tool although you can do some of the same sorts of things, it is not really primarily intended for that purpose. And by that I mean doing things like automatically returning statistics and distributions about your data, etc. You can get there with Power BI, but it is work.
