Presentations

Many moons ago when I first started as an Oracle Developer, I worked on a project with Penny. I wasn't under her employ then, but we were playing with materialized views in an 8.1.7 database. Fairly cutting edge at the time she suggested I do a presentation on it for the conference. Green as I was straight out of university I graciously declined, but ever since I searched for a topic I'd be confident in presenting. One day on a blog I stumbled on someone's response to a simple query that suggested using the Model Clause and for some reason this peaked (not piqued) my interest. I've never looked back since and ideas just keep coming.

So to those contemplating it, just go for it. It's like riding a bike. And you learn so much about Oracle when you're essentially forced to tinker & play.

Below is a list of presentations I've done so far.
(And yes, it turns out I'm a fan of alliteration)

Updated November 2011 - Added link for my Oracle Apex Security presentation

Oracle Apex 4.1 Security  ( prezi | bookmark )

There have always been many options for securing Oracle Apex applications, and many of them don't require much effort - just a little understanding.

This presentation will cover all things Apex Security. Scott covers discussions and examples of many of Apex's security features, including changes to Authentication & Authorisation in 4.1 towards using plug-ins.

Oracle Apex Performance  ( pdfprezi | bookmark )

Over the years there have been countless technical and social presentations doting on 5, 10, 12 ways to improve this, that and the other.

I will go through various performance tweaks (not tweets) for Application Express without limiting myself to a golden number.

These improvements will vary from simple PL/SQL refactoring; to monitoring for bottlenecks in your application; to cutting down maintenance time - which relates to the performance of you as an Oracle developer with only 24 hours in a day.

We may even visit a little Apex instrumentation on the way.

Apex with Oracle Text ( pdfinline | bookmark )

Oracle Text is a facility within the database that provides more advanced indexing & search techniques - including the ability to index documents stored in your database; on your server; or even the web!

Now you can incorporate this functionality into your web application using Application Express.

This presentation will demonstrate how easy it is to combine the two, and give you a platform for further expansion and exploration within a very powerful product.

Trials & Tribulations of an Oracle Forms -> Apex Conversion ( pdf | bookmark )

Abstract: One of the hot topics these days questions how long you should keep hold of your long standing, hard working Forms application. Oracle support timeframes for Forms has been quite fluid over recent years and ultimately you may need to make a move..

Depending on the size and complexity of your application, a number of options present themselves.
Application Express is one such option. The question remains, however, is there some black box tool we can use to plug our Forms in and have it pump out Apex pages? And how much assistance does this tool need before and after the conversion process?

This presentation will cover some of the considerations you may need to make when contemplating this event. We'll show what happens when you convert a form with various types of components and reveal the gaps, if any, you'll find at the other end.

Let's not forget the other components of our Forms application. What about PL/SQL libraries, reports, menus? Is it worth tackling some of these items manually? We shall see...

Oracle Documentation ( inline | bookmark )

Abstract: If you're a database developer, regardless of whether you have 6 months or 6 years experience, you need a good reference manual.
By good, I mean one that you can locate what you need within seconds. I know you know what I mean...

I'd like to show you how easy the free Oracle supplied documentation really is to use. And if for some reason it still doesn't cater to your needs, I'll show you some other methods and destinations that might save you a few headaches.

In this short presentation, I'll show you how to find most day to day documentation requirements in 2 clicks, maybe 3 if you're unlucky - without connecting to the net.
You might also hear some other new words such as Ubiquity & Bookmarklets.

11g New Features ( inline | ppt | bookmark )

Abstract: There are a wealth of new features available in the 11g database release. This presentation touches on SQL & PL/SQL features I found of interest, and concentrates particularly on virtual columns.
Relevant scripts are available here.

Creative Conditional Compilation ( inline | ppt | bookmark )
Abstract: Oracle released a feature in 10g Release 2 they thought worthy of facilitating in previous versions via patch sets - so I thought it was worthy enough for a closer look.

Conditional compilation isn't a foreign concept in the programming world, and for the developer aficionado it's a wonderful paradigm to explore.

Conditional compilation was designed with the main intention of being able to create database version specific code. With the recent advent of 11g, developers can actually start adding 11g features to their 10g code today!

However it provides the savvy PL/SQL developer to enhance their code in more ways than just gearing up for the next release… Dust of your software engineering hats and discover how to utilise conditional compilation to explore concepts such as latent self tracing code; latent assertions; and enhanced prototyping for your unit tests.

This seminar will illustrate several examples of conditional compilation that will open your mind; ultimately benefit your users; and can be implemented as far back as 9.2!

Be a Bulk Binding Baron ( inline | pdf | bookmark )

Abstract: Developers - If you are not using Bulk Binds you are not writing PL/SQL efficiently!

Bulk binding has been around for a long time, yet there are sites out there that don't utilise this feature to its full extent, if at all. Every release of Oracle improves on this functionality so obviously it's a topic worthy of consistent awareness.

In PL/SQL and SQL, there are a few nifty features related to bulk binding you may not have seen - it's not all about BULK COLLECT. Whether you're on 8i, 11g or anything in between, you'll benefit from the concepts described in this seminar and become a Bulk Binding Baron!

The Model Clause ( inline | bookmark )

Abstract: The session will breakdown the Model clause into its fundamental components and provides some basic real-world examples to demonstrate its greater potential.

Though most developers have heard of the SQL Model clause in 10g, many may baulk at the idea of using it - daunted by seemingly foreign syntax that might well have come out of a FORTRAN program.

Look a little closer and you'll find it's just like building a spreadsheet. Concise, easy to read syntax that provides the functionality for demanding calculations that would normally require elaborate joins, unions, analytics or PL/SQL. In addition to the development and maintenance burden, we are also faced with the all too familiar problem of business customers duplicating data to an Excel spreadsheet that is shared and erroneously modified around the workplace.

This session uses the Model clause as a high performance tool that can simplify approaches to every day problems. It demonstrates that Model is an extension to SQL that forms multi-dimensional arrays with inter-row & inter-array calculations that automatically resolves formula dependencies.
