ADF DVT: Visualizing valid periods using Project and Scheduling Gantt Charts

0

by Lucas Jellema in , ,

In a recent article – Advanced SQL to find valid periods – juggling with outer joins, running totals and analytical functions – I discussed how to use Analytical Functions in SQL to cleverly (!) derive the valid periods from a database table that contains periods of inclusion and exclusion. A valid period is a period for which there is at least one inclusion and for which there is no exclusion. I used several powerpoint based graphics to illustrate the business case. For example:

to depict the periods of inclusion and exclusion and this figure to demonstrate how to derive the valid periods (the blue bars):

After completing this article – and fiddling around in Powerpoint quite a bit – I realized that for visualizing data in a table, I have a perfect tool at my fingertips: the Data Visualization Tags (DVT) in ADF 11g are created for this very purpose: turning data into information through visualization. And this rich library of DVTs components contains – in addition to fairly straightforward visualizations such as bar charts, pie charts and line graphs – also more complex visualization components such as the Bubble Chart, Thematic Map and Gantt Chart.  The Gantt Chart has three More >

During the AMIS ADF Masterclass I showed how to take a picture from within an ADF Mobile application, attach it to an Email and send that email out to several recipients. To top it of, I even added the GPS coordinates to the subject, so you know where the picture was taken. And all of that with the push of one single button. Sounds complicated ? Well actually it is very simple. (more…)

Als sluitstuk van de jaarlijkse Oracle OpenWorld conferentie brengt AMIS een whitepaper uit. Een handzaam document waarin het volledige verhaal van Oracle OpenWorld 2012 is gebundeld.

Een team van AMIS was tijdens de conferentie in oktober nadrukkelijk aanwezig; als sponsor, deelnemer, netwerker en spreker – en als aandachtig luisteraar en analist.

Zeven Oracle-specialisten van AMIS hebben deze whitepaper samengesteld waarin de visie, plannen en aankondigingen van Oracle zijn gebundeld. In het maar liefst 47 pagina’s dik document wordt niet alleen het verhaal van Oracle samengevat, maar geeft AMIS ook haar eigen duiding en waardering van het verhaal.

De whitepaper is hier gratis te downloaden.

Deploy ADF essentials app on Tomcat 6.x

by Daljit Singh in , , ,

Recently I gotinvolved in a project where the customer requirement was to deploy an ADF application on Apache Tomcat 6.x. This ADF application would be rolled out with ADF Essentials.  Which OTN describes as following: “Oracle ADF Essentials is a free packaging of key technologies from the Oracle Application Development Framework that can  be used to develop and deploy applications without licensing costs”.  Thus tremendously decreasing operational costs.

The plan of action  was to install and configure Tomcat on a test environment and verify that the application would be successfully deployed and work as designed. The following steps were taken to install Tomcat:

  1. Download and configure Tomcat
  2. Application specific configuration
Tomcat download and configuration

Download the stable version of Tomcat 6.x In our case this was Tomcat 6.0.36. (zip file). Unzip the downloaded zip file to a folder. We chose to unpack the files in  ”/u01/app/apache/apache-tomcat-6.0.36″.

Create a script to set environment variables $CATALINA_HOME and $CATALINA_BASE  pointing to “/u01/app/apache/apache-tomcat-6.0.36″ . The two environment variables have the same value because this is a single instance More >

AMIS Masterclass Advanced SQL – scherp je SQL skills in een pittige en praktijkgerichte dag – maandag 10 december

by Lucas Jellema in , , , , , ,

Of je nu ‘klassieke’ Oracle applicaties ontwikkelt, met APEX bezig bent, een SOA landschap inricht of een Java/JEE (bijvoorbeeld ADF) applicatie bouwt: het fundament van veel van wat je doet is de database. En de crux van optimaal gebruik van de database is en blijft SQL. Dit bepaalt performance en schaalbaarheid en ook ontwikkel-productiviteit en zelfs pure functionaliteit. SQL kan veel meer in de Oracle Database dan de meeste – ook heel ervaren ontwikkelaars – weten. Tussen Oracle7 en Oracle 11gR2 is er met eigenlijk iedere release enorm veel kracht bijgekomen in de handen van “SQL componisten”. En je doet jezelf tekort als je niet regelmatig je SQL vaardigheden aanscherpt tot de nieuwste technische mogelijkheden en vooral de praktijkbewezen evolutie.

Op maandag 10 december verzorgt AMIS – Oracle specialist in Nieuwegein, sinds 1991 – een Masterclass Advanced SQL. Waarin voor ervaren SQL ontwikkelaars een overzicht wordt gegeven van de evolutie van de database – tot en met 11g Release 2 en met hier en daar al een vooruitblik naar 12c.
