I need to design a database schema for a set of data and I watched a Coursera video where the professor talks about "Higher-Level Design Tools" but doesn't say any example.
I'm putting a link for my screenshot below so you can understand what I am talking about. My question is: how do theses tools work? Are there good examples?

I think that the professor is talking about design tools such as Sybase PowerDesigner.
These tools allow you to design databases in different levels of abstraction from high level (Conceptual Data Model) to low level (Physical data model), they also provide tools for generating diagrams and even the final code depending on your database type.

I am new to StackOverflow so please do correct me if I need to provide any more information.
I am trying to integrate an anomaly detection into the PostgreSQL database system by plugging into its backend.
I would like to know if there is any place where I can find extensive back-end coding or integration examples. I am looking at papers regarding this topic and, so far, I have found a few which talk about the methods that the queries are classified and used for anomaly detection.
If you do know about any websites which might help me, please do provide links to the sites.
Thanks!!
Look for "hooks" in the PostgreSQL source tree. Studying the source of the auto_explain and pg_stat_statements contrib modules, which track query execution, will show you the way.
The source is its own book: it is well-documented and interspersed with README files that explain the design.

I've been developing almost exclusively C-code for the past few years. I'm currently looking to brush up on my Object Oriented Design skills. Can anyone recommend any resources that have a decent set of short object-oriented design problems with some possible solutions/analysis? I'd ideally like something that was a small enough problem to sketch out and design in during a question in an interview that can be completed/analyzed in 15-30 minutes.
Thanks!
Look at my answers to the below two posts
Workbook on object oriented design (object model domain, system sequence diagrams, interaction diagrams)
Software Design questions for Software Engineer Interview

I'm looking to learn set theory. My coding history has been primarily practical and I'd like to move more into the theory side of things. I think I understand the basic concepts of set theory but I know nothing about its applications, its notations, and operations you can perform on sets.
Any resources that could point me in the right direction would be great!
Set as a Data Structure
General theory
Set Theory for Computer Science
What practical applications does set theory have?

What's the best tool to reverse engineer an SQL Server 2005 to an entity-relationship Model diagram? Could it be done usin SSMS?
Do you need more than the Database Diagram functionality provided in each database in SSMS? This will generate a diagram with any tables you choose and any relationships that are defined.
I've also used Visio which is useful if you have a large number of tables and need more control over the diagram.

I'm looking to locate a good resource (book or otherwise) on safety critical systems development techniques/methodologies, especially something that will cover both hardware and software . I have a sound working knowledge of C/C++, so even if it is just code on SourceForge etc I would still appreciate a link to it to have a browse.
Thanks.
The podcast Software Engineering Radio has some episodes which talk about e.g. real-time and fault tolerant systems which I found very informative. Those episodes also had good references to books.
