Storing and Retrieving the Initialization and Configuration Data for Applications

  • Article

All developers hit the problem of how and where to store and set their configuration, profile, or initial data. A long time ago, it was generally decided that simple text files containing key/values were best, stored with the application. After all, you are relying on being able to entice busy people to get the permanent settings right for their requirements, folks who are generally not interested in your elegant computer science constructs. Not only that, but the settings must be parsed very quickly and efficiently, otherwise a process that uses the tool will slow to a crawl.

Bad Data and Dirty Databases

  • Article

Many years ago, my wife and I wrote an article for Datamation, a major trade publication at the time, under the title, “Don’t Warehouse Dirty Data!” It’s been referenced quite a few times over the decades but is nowhere to be found using Google these days. The point is, if you have written a report using data, you have no doubt felt the pain of dirty data and it is nothing new.

Mathematicians and SQL

  • Article

Georg Ferdinand Ludwig Philipp Cantor is considered the creator of set theory, and his theories are the basis for the naïve set theory you learned in school. But there are lots of other mathematicians you should know, such as Hilbert, Frege, Russell, Zermelo and Dedekind. They made a lot of contributions, too. Hilbert Hilbert is […]

Data Element Names and Scoping Rules in SQL

  • Article

How you name data elements in databases and applications programs has often been a matter of personal taste. Decades ago, when I worked for state government, there is a COBOL programmer who would pick a theme for his programs. The paragraphs and variables would be named based on the current theme. One of his programs […]

Question of the Day

Restoring On Top II

I have a database, DNRTest, that has a number of tables and other objects in it. The other day, I was trying to mock up a test and ran this code on the same server: 

-- run yesterday
CREATE DATABASE DNRTest2
GO
USE DNRTest2
GO
CREATE TABLE NewTable (id INT)
GO
Today, I realize that I need a copy of DNRTest for another mockup, and I run this: 
-- run today
USE Master
BACKUP DATABASE DNRTest TO DISK = 'dnrtest.bak'
GO
RESTORE DATABASE DNRTest2 FROM DISK = 'dnrtest.bak' WITH REPLACE
What happens?
