I have a keen interest in "embedded databases" like Berkeley DB, SQLite, eXtremeDB etc and am very curious as to what "databases" the major Game engines (or games in general) use to persist their data?
I would assume some of them use thier own "in house" persistence layers / databases.
Any ideas?
Most major game engines don't use any embedded database. They use config files or skripts with data instead.
IMHO embedded DBM for typical game engine is overkill.
Of course MMO-Engines use DB, but not embedded.

I'm developing an application for iOS, Android, Windows Phone and in the future a web version of it.
I'm relatively new in databases so I started learning a bit of SQL and PostgreSQL.
My application is for industry and will show pruducts and other information relatively with that.
My question is should I use SQL database or NoSQL database, and which should I use?
Thanks!
Use the database that makes it easiest to model your data. If your data is relational, use a relational database. If your data is best represented as a document, use a document database. If your data is best represented as a graph, use a graph database.

I often heard about CryEngine, Unreal Engine, etc., but it is hard to imagine what it is about and why some are more powerful than others.
Can I say it is a high level library?
Can I say it is a high level library ?
I would say no, because game engines are typically more like operating systems than they are libraries.
Fabien Sanglard's code reviews of some famous older games are exceptional, and give some great insight into modern game engines. I especially recommend the Quake source code review; in many ways Carmack's Quake engine is the precursor to almost every current-gen 3D engine:

I wish to refine my skills on t-sql (remote procedure calls etc) and making queries on DB's. I have a macbook and would like to know is there any software i can use to accomplish this? Ideally i would not like to install any software on this computer at all but if i have no choice then so be it.
I highly recommend SQL Fiddle. You can create schemas on many types of DB (different versions of SQL Server, MySql, Oracle etc.), practice writing queries, and even send the link to people so they can practice on the same schema/example data as you.
Here is a place where you can practice making queries without installing software.

I'm wondering what are recent advances in relational database theory and related domains? I'm interested in new approaches, query languages (alternatives to SQL and/or extensions to it), products (proprietary and open source, though I'm much more interested in open source) and research projects developed in last years.
I am not versed in the subject but there was a very nice project based on XML structures over RDB that caught my eye a few years back and now seems to work perfectly.
Have a look at http://exist.sourceforge.net/ to see a nice approach to RDB used to build a more flexible storage system with XQuery as the query language. You should like it, it's open source.
