Follow-up on “Accounting in 2016”

Leider ist der Eintrag nur auf English verfügbar.Two months ago, I wrote an article on how accounting in 2016 still is a manual and tedious process. What made me write this article in the first place was the problem that I couldn't automatically get the bank account statements for my business account into my accounting software because my bank's online banking service and my accounting software have incompatible import / export file formats and neither exposes a public API for facilitating ...

Why motion matters in UI design

Leider ist der Eintrag nur auf English verfügbar.UI designer Craig Dehner wrote this interesting article about why he thinks motion design is the future. I wouldn't necessarily use such grandiose terms but essentially I agree: Motion design might not be THE future but it'll certainly play a vital role in current and future user interfaces.

Although dropdown menus accommodate most list-based use cases using them often doesn't take the specifics of the use case at hand into consideration. As pointed out by ...

I really appreciate the idea of promoting and sharing best practices for database systems. While object-oriented software design ...

Hands-on SQL Tips: Sentinels And Window Functions

Leider ist der Eintrag nur auf English verfügbar.Sometimes when displaying data in an application you want the amount of data (rows, individual data points etc.) to be limited for the app to stay responsive and to allow the user to more easily scan and browse the data set. In SQL this is commonly done using a LIMIT statement: [crayon-697513b08d2f6972518447/] Now, what if you want to not only display the data but also inform the user in case the total number of rows in ...
