An enterprise portal is the converged "hub" of multiple, complementary information management solutions, including document and content management, information search and retrieval, knowledge management, team collaboration, workflow, and business intelligence. In this article, we describe what an enterprise portal is and give you a brief overview of Sybase Enterprise Portal. Then we take a closer look at the portal and go over some of the installation requirements and steps for the Information Edition of the portal. We also delve into how to use a portal and build components (called portlets) for the portal using PowerBuilder. Finally, we include a section on portal security, an extremely important aspect of having a portal. Whether you write your own portal software, are thinking about using portal software, or are already using the Sybase Enterprise Portal, this ... (more)

LDAP with EAServer and PB 8.0

In Part 1 (PBDJ, Vol. 9, issue 6) I discussed directory services and how they provide authentication, access control, and finder services for our application. In Part 2, I explain how the JNDI API lets us easily use LDAP.

In this article I'll show you how to play MP3 files with your own "sound machine" written in PowerBuilder. But before we start to implement it, you should first understand what MP3 is. MPEG-1 Layer III, MPEG Audio Layer III, or MP3; it's all the same. I'll use the name MP3 from now on.

The original name was EUREKA project EU147, Digital Audio Broadcasting. Dieter Seitzer, a professor at the University of Erlangen,... (more)

I've seen a lot of shops or individuals start working with PowerBuilder on their own, without leaving the office or house and traveling to a certified Sybase trainer or education center. Well, what can I say? I don't recommend this type of "learning by doing." The "Fast Track to PowerBuilder," the advanced class in "Mastering DataWindows," and the second part the "Advanced PowerBuilde... (more)
