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.

Program A is good at collecting data while Program B, in another language, is good at creating REST APIs. Is it possible to connect these two with a single database that A and B will read and write to? Performance for database operations is not really an issue in my case.
Sure this is possible. Databases typically can handle multiple connections from different programs/clients. A database does not really care which language the tool that is making the connection is written in.
Short edit:
Also most databases support "transactions". Which are used to cover that different connected clients do not break consistency of your application data while reading and writing in parallel.

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 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 was reading the book on DW and it says knowledge of spreadsheets will be good for DW.
I have some time left before applying for jobs.
Should i start learning microsoft excel in advanced for DW
I know only basic spreadsheets not advanced
Do get into the Datawarehousing field, it is fundamental for you to be "datamart" litterate.
First start here :
http://en.wikipedia.org/wiki/Data_mart
Then, dare taking a look there :
http://www.information-management.com/infodirect/19991120/1675-1.html : it will give you an awesome step back and you'll be able to reply to questions like a pro, who has seen datamarts in real-life ecosystems.
And last, but not least, get as familiar as you can with the Map Reduce theory. Among others, take a jump here :
