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)
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.
The Java Naming and Directory Interface (JNDI) is an application programming
interface (API) that provides naming and directory functionality to Java
applications. It's independent of any specific directory service
implementation, thus a variety of directories - new, emerging, and already
deployed - can be accessed the same way.
One of the biggest problems in an enterprise is deploying the application.
Usually you have to deliver a new release of your application to several
hundred workstations. This may be a time-consuming and very cost-intensive
Think of rolling out the newest and coolest version of the order application
of your enterprise: this superior version has so many new functionalities
that your users will love it.
When we think about rolling out a new version, we must keep a few things in
mind: The cool new version has to be packed for distribution. Database
conversion scripts have to ... (more)
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. Fraunhofer
Gesellschaft (FhG) situated in Germany was the original company/founder in
the development of the MP3 standard and received patent protection for it in
1989. The original name was EUREKA project EU147, Digital Audio Broadcasting.

I've heard it many times: training in general (not only Sybase classes) is so
expensive. I agree, but believe me, it's worth every cent (I'll just be
discussing the Sybase classes in this article).
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
