A 'To Laugh or Cry' item was posted on the LAUGH/CRY page.
Here's an exchange between its author and myself:
I was thinking about database skills. When I started in the nineties, and systems were moving from Cobol to RDBMS, database and design skills were really valuable. Now, as much as we know that DB skills are important and valuable, it seems to be the GUI that is more important. At least in management's mind. :( At my alma mater, no student is studying the database track now. They either do app development, or networking. When does this mean for the future?
That is why the new generation of products are either applications and files, or labeled DBMSs when they are really application-specific DBMSs. Many practitioners do not distinguish between DBMS, applications, network and OS functions. It's all one big lump.To which I add: This is also the reason application developers like object-orientation: it is a programming, not data "paradigm".

The following Advanced Database Design and Implementation - Course Outline requires no comments for the reader possessing foundation knowledge. It is good evidence of academia pursuing industry fads rather than leading it with science.
This year the course will examine the following two contemporary fields in the database systems area: XML Data Model and XML Databases and Data Warehousing.Interestingly, the pre-requisite is familiarity with "Relational Data Model, Structured Query Language (SQL), Relational Functional Dependencies and Normal Forms, PostgreSQL Data Base Management System."
XML Data Model and XML Databases will comprise approximately 65% of the course. There, we shall consider topics such as: XML documents, Document Type Definition (DTD) and XML Schema, XML constraints, XML query languages, Types of XML Databases, Mapping XML data to relational databases, Publishing relational databases as XML documents, and what research is going on in the XML database area. The practical experience will be achieved through the use of XML processors like xmllint and the native XML database management system eXist.
By the end of the course, students should be able to:
- Design well formed XML documents that are valid with regard to a given DTD or XML Schema and thus develop the ability to solve practical engineering problems (BE graduate attribute 3(f)),
- Analyze a part of the real world and design a corresponding XML DTD or Schema in XML normal form and thus develop the ability to formulate and build efficient models of complex systems using principles of engineering science and mathematics (BE graduate attribute 3(b) and BE graduate attribute 3(c)),
- Design faithful models of a part of the real world using XML database constraints and thus develop the ability to apply mathematical and engineering science in solving engineering problems (BE graduate attribute 3(a)),
- Use available web sources to learn about the eXist XML database management system and define XQuery queries and XUPdata updates of an almost arbitrary complexity against a native XML database and thus develop the ability to look for additional information from pertinent sources (BE graduate attribute)...
Can't figure out why.
On the lighter side: Models and met-a-date.
