OOW2011 - Announcing Oracle NoSQL


NoSQL databases have already been around for a long time. Even Oracle owns one: Berkeley DB. Other well known databases are Voldemort, MongoDB and Cassandra.
A NoSQL database contains only key-value pairs and targets on only simple operations: store and retrieve data. Any relationships and other rules should be enforced by the application itself. A NoSQL databases has a small footprint, is embeddable, (very) fast, scalable and easy to use and usually runs on a lot of operating systems.
Therefore the sweet spot of NoSQL databases is processing loads of simple and unstructured data, like messaging, queueing and user web clicks. Not surprising that the big social networks, like LinkedIn, Facebook, Google and Amazon are heavy users of NoSQL databases. For some more advanced use some NoSQL databases have options for concurrency, transactional processing and high availability. Of course you can store this kind of data in a relational database, like the "regular" Oracle database as well, but that comes with a much higher price tag. An Oracle database can do so much more than just store data, but even if you don`t need those features, you still have to pay for them...
This Monday Oracle announced their knew Big Data Appliance in order to acquire, organize and analyze large volumes of simple, unstructured data in ann easy way. Part of this appliance is the new Oracle NoSQL database, which is - surprise, surprise - based on Berkeley DB. But, unlike most competitors, an Oracle NoSQL has, next to a C++ and Java API, also a SQL API! So NoSQL doesn`t mean no SQL at all, but Not Only SQL...
Oracle NoSQL will be available in two versions: a Community Edition which is free and open source and an Enterprise Edition. The functionality is the same, there is only a difference in the licensing... I am very curious how this will land in the, usually very independent and open source minded, NoSQL world!

Showing a success message after closing a modal dialog

APEX 5 comes with Modal Dialogs out of the box. Very neat. Especially for adding and changing data. And to minimise the number of time a user has to click, it could be useful to add a "Close Dialog" process after the actual data processing. When the data processing fails, the Dialog stays on top showing the error. When data processing runs fine, the Dialog is closed ... without any confirmation. And this might be scary for a shaky user.

So how can we provide the user some feedback? On Page 4 of the Sample Dialog Application you can see one solution: up on a Dialog Closed Event on the parent page it does a redirect to refresh the parent page appending the success message of the "Close Dialog" process. This has two drawbacks. First, it probably refreshes more than necessary. And second, if you're using multiple layers of dialogs (dialogs that open other dialogs) the message appears in the "parent dialog".
As an alternative you could follow these steps: 1…

It's happening again ... running for the ODTUG Board of Directors 😉

For the third time in a row I'll be running for ODTUG's Board of Directors. But after ending as a runner up twice, I am sure I'm going to make it this time! But not without your help!

My campaign statement this year is:
I have been attending and presenting at Kscope conferences since 2007. This not only resulted in a vast amount of knowledge, but also - and even more important - a huge number of friends from all over the globe.  I want to see ODTUG grow and spread this community feeling even more! 
My experience as an attendee, presenter and content lead has provided the basic foundation to be a director. Next to that, my personality and (global) network will be beneficial to the whole board and organization. 
Since March I have served on the Board of Directors in a limited term for a Director who stepped down due to a career change. This has allowed me to have unique insight of all the things that are going on in and around the ODTUG organization. As the train was already ro…

APEX 5 New Static File Features

In APEX 4 you could upload files - like CSS files, JavaScript files, Images and whatever else you like - into the APEX Repository. When you navigate to Shared Components, there is a Files section that offers three different options:
CSS Files are always uploaded (and changed !) for the whole Workspace. For Images and Static Files (usually JavaScript) you could choose whether they should be available for the whole Workspace or for a specific Application only. And if you had a lot of files - e.g. a lot of images - then you had to go through the upload process one-by-one. But that's usually a one time only thing. If you make changes to the CSS and JavaScript files - and that's a continuous process in development - then you had to delete the existing file and upload the new one. Over and over again. And meanwhile fighting the cache of the webserver and your browser.  And another irritating issue: You couldn't use relative references in your CSS or JavaScript files as they just…
