APEX Presentations ~ Through the Years

I was recently asked to summarize my APEX Presentations. I realized I had them in several places, but not in one consolidated space. So here it is – a summary of my APEX Presentations through the years:

APEX 5 Interactive Reports

Updated for the APEX 5 release, these links contain the presentations from KScope 15, and white papers as published in RMOUG’s SQL>UPDATE magazine.

For APEX 5, Interactive Reports have been reengineered from the inside out. Any developer who uses IRs, has made customizations for appearance or features or performance outside of the standard API’s, even pagination plugins, needs to be aware of the new CSS and JavaScript engine.  APEX 4 and earlier customizations will likely not work in APEX 5 without some refactoring. Be prepared!

Migrating Critical Business Application to APEX – Successfully

Presentation: Migrate Business Applications to APEX, Successfully – Presentation 

I had a blast at COLLABORATE14 in Las Vegas, NV, April 6-11, 2014.  I had a chance to catch up on Oracle 12c skills, learn more about ADF Mobile with APEX for hybrid mobile applications, XQuery and XML DB and of course refresh friendships with all those at IOUG.  My Friday presentation was on Migrating Critical Business Applications to APEX, covering tips and tools for migrating any legacy app to APEX.

APEX Data Load Options, or, How Do I Load Data, Let Me Count the Ways …

Presentations: APEX Data Loading Options

There are many many ways to load data into an Oracle application. This presentation discusses data load methods specific to APEX – the data load wizard, external files, custom methods and using the APEX Listener for a true MS Excel file upload. This is practical what works, what doesn’t information to help one decide the best approach for data loading problems.

Meaningful Maps, Gantts and Charts

Presentations: Meaningful Maps, Gantts and Charts

APEX 4.0 introduces improved charts and maps, but how to make sense of them? This presentation covers all the basics for understanding APEX 4.0 Charts, Maps and Gantt Charts.  Plenty of information to get one building meaningful charts and maps in APEX applications.

Tight Tabular Forms

Presentations: Tight Tabular Forms

APEX tabular forms are handy, but kind of loose, if you use them out of the box. This presentation covers the improvements in APEX 4.0 for tabular form validations, plus some tips on adding validations using the APEX_APPLICATION arrays, and building manual tabular forms using the APEX_ITEM API.

Migrate BI to APEX: What Works, What Doesn’t, and Lessons Learned Along the Way

Presentation: Migrate BI to APEX – What Works, What Doesn’t, and Lessons Learned Along the Way

This presentation covers a real migration from a major-vendor BI tool to APEX Interactive Reports for end-user information needs. Covers feature considerations such as drills, pivots, output; dynamic crosstab options and construction, including use of 11g PIVOT and AMIS PIVOT object type solution.  Careful crosstab query construction makes APEX Interactive Reports more powerful than one may think. APEX 4.0 new features address the needs for user-defined grouping, shared reports, scheduled report delivery, multiple views of the same data set and improved charting.  Check it out!

Note:  I am working on an APEX 5 version of this presentation – improvements in APEX 5 interactive reports, including the PIVOT feature, may tip the scales and make a switch from an expensive, underutilized BI tool to APEX a better use of resources.

Oracle Application Express: Tactics to Tackle APEX Bugs

Paper:               Tactics to Tackle_APEX Bugs,  Paper

Presentation: Tactics to Tackle_APEX Bugs, Powerpoint

Know your application, know your tools, have a plan, and always remember that you know some stuff. You can debug Application Express apps and stay sane.

APEX development is a breeze, until something goes wrong and there’s no obvious clue of what happened or how to fix it, and there’s no UNDO. Or is there? This session presents tactics to tackle common APEX problems such as MRU internal error, Browser errors, SQL and PL/SQL issues, HTML, and JavaScript problems. We cover triage, debug tool options, and debug tactics, and then demonstrate applying those strategies to tackle common APEX problems.

This paper and presentation were written for APEX 4.0 (or earilier?) ~ APEX debugging techniques are much improved now! However, the strategies and tactics for addressing bugs: knowing your app, knowing your tool, instrumenting, researching first and using the forums still apply.

Oracle Application Express Interactive Reports: The Good, The Bad, The Ugly

Presentation: APEX Interactive Reports: The Good, The Bad & The Ugly

Paper:               APEX Interactive Reports: The Good, The Bad, The Ugly

I had fun writing this paper, mainly because the movie (old western, Clint, of course) theme song played in my head, and our house is defnitely a Clint-John Wayne-Sam Elliot-Any Old Western neighborhood.

Oracle APEX Interactive Reports have many Good points, but one-size does not fit all, so we developers still have some cleverness to apply to meet end user requirements in all cases. This paper outlines the Good, the Bad, the limitations, and shows some easy CSS edits to address the Ugly, the default appearance. Have fun!

APEX Interactive Reports offer amazing functionality out-of-the box, but this wealth of features comes with limitations. This session presents the Good, the Bad and the Ugly of APEX IR, then details and demonstrates workarounds to address the Bad (the limitations) and the Ugly (the appearance). Learn how to limit Search and Activity features for different user roles, how to eliminate part or all of the Search and Activity Bars and how to customize the look-and-feel to fit your corporate template.

(As with all my papers, I will keep this post up to date with the latest version of the paper.)

APEX Cheat Sheet

Download the APEX Cheat Sheet paper from here: APEX Cheat Sheet

When starting out with Application Express, it can be a bit confusing in terms of what syntax to use where, how to effect the item alignment needed, how to customize the look-and-feel… in general, how to get productive. Tha APEX Cheat Sheet paper is a collection of tips, how-to’s, syntax conventions and tricks to accelerate a developer’s APEX learning curve. The APEX Cheat Sheet paper has grown to be much longer than a “cheat sheet” but it does provide a solid quick-start to APEX development.

Note: While written for erly APEX versions – APEX 3! – some of the basics still apply, like the f?p syntax.  Someday I will do another Cheat Shet- the problem is there are so many new features, I will have to do multipe cheat sheets for each major feature.

APEX Under the Covers

Paper: APEX Under the Covers

In working with Oracle Application Express I have found the best way to learn “how they did that” is to look “under the covers” at the APEX code … The way to do that is to download an application, install it in my builder, and view how the author implemented the features of interest.

The white paper and presentation APEX Under the Covers walks the reader / viewer through the learning process of looking under the covers at some not-so-standard features implemented in APEX. The examples are not rocket science; they are intended only to get the brain thinking along lines where the reader may not yet have ventured, suggesting a few different approaches to achieving an end within APEX.

Note: This presentation was written for APEX 4, but the approach is the same with APEX 5 and beyond – learn from how they wrote APEX. For APEX 5, use and LOOK AT how they wrote the packaged applications. This is free training at its best!

APEX Debug Options

Paper: APEX Debug Options

Debugging Oracle Application Express can be a conundrum.   It’s PL/SQL, but I cannot see it, and I cannot step through it. PL/SQL generates the page, but I do not have access to the APEX page generator. There is JavaScript and CSS and HTML … Where to start?  The truth is there are many avenues for debugging APEX; some APEX-supplied, some external to APEX. The paper and presentation APEX Debug Options describes both APEX-supplied utilities and tools external to APEX for debugging APEX applications.

~ Keeping it Fresh: Cost-Effective Training

Layoffs, economizing, more for less, and oh-by-the-way keep up with the latest in Web development, languages, data modeling, coding techniques, testing, quality, the latest App Servers and find time to relax a bit and network with your peers. The temptation is to postpone or skip all training. I suggest however that this is the time we need training all the more. I maintain the most cost-effective training can be found at our user group conferences. Attend! Volunteer – get involved! IT is the most efficient, cost-effective way to stay current and learn new technologies, and you might have some fun along the way.
