Extract Database Object Header Comment with Powershell

Some database objects in my current project are created by ORM or a PL/SQL-framework and hence need not to be put under source control; All manual created objects are strictly stored in source control.

Every database object definition under source control is stored as DDL file. And every file starts with a comment about the database object properties. Once an object is created in database and it's definition is added to source control it's time to automate some repeating stuff like creating a comment header. For the current project I use Windows Powershell for this. All stuff which needs to be generated is done via PL/SQL. The return value of these functions is very simple : a collection of strings.

Zone Alarm !!!

Hi,

the title is not a title of a Science Fiction film or of a Hackers memories intruding networks or a gaming title but is SUN Solaris related. SUN Solaris 5.10 introduced a virtualization concept called Zones. A Zone is like a logical/virtual machine on a SUN Server Hardware. Zones are nearer bound to resources then for example a VM like VMware or Parallels (on Mac); This keeps the frictional loss of resources lower.

At our customer site database servers are driven in SUN Solaris Zones. Resources dependend on the implementation of a zone could be shared between the Zones. Hardware is better utilized.

But one drawback is here - it's to specify performance;

Terracotta - the return of OODBMS?

Do you remember?

About 10 years ago OODBMS (Poet, Gemstone, Versant, ...) seemed to be starting to replace RDBMS; The idea for using OODBMS was simple - if the programming model is OOP why not persist Objects with an OODBMS directly instead of populating it's properties and class hierarchy into a couple of tables? It was the reason Oracle 8 came with object relational features; But they (OODBMS) failed for following reason:
