Hello everyone,

I am new to Google App Engine platform and I like it a lot especially with Python. However, I am very confuse with Entity Transactions and Entity Group. Can someone here could explain it in simple and clear? 

I've been googling this for a month but still unclear. Example, I have two tables: Employee and Department, how does Entity Grouping or Transaction takes place? (I know Datastore is not a relational db, I just want my question clear) .

I hope someone here could finally enlighten me up with this :)

+Anastasios Hatzis Thank you so much! it's such a wonderful explanation, thanks for the effort in constructing those very long paragraphs.

I am afraid to say that it is very hard for me to adapt from RDB's to Datastore 'cause they are so much different. I'm still imagining tables and columns inside a database.

Can I ask once again? :) (honestly, I'm so ashamed for not getting this thoroughly)

If you would draw these Employee and Department and their children, how would that look like?

For example, I have a table System_Variables which contains the following columns: 
id
department_names 
access_levels

The department_names column contains these data: 
HR
Workforce
I.T.

Also, the access_levels contains these:
System Administrator
Supervisor
Guest

Another table is also named Users which contains the following columns:
id
Name 

How will it look like in Datastore Modeling?

If this GnuTLS debacle has taught us anything, it is that if you want an OS as safe as humanly possible, why would you settle with anything less than a #Linux one?

Ubuntu Touch Emulator: Installation And Usage In Ubuntu 14.04, 13.10 And 12.04: http://www.webupd8.org/2014/03/ubuntu-touch-emulator-installation-and.html

A while back, Canonical released an experimental Ubuntu Touch emulator running Unity 8 and Mir. Back then, there were a few bugs, including a nasty one on 64bit that could break the system, but they were fixed and although the emulator is still pretty slow, I though I'd write an article on how to properly install and use the Ubuntu Touch Emulator in Ubuntu 14.04, 13.10 and 12.04.
