Saving Current Values with Cascading LOVs - 0 views
-
"Saving Current Values with Cascading LOVs A friend, Monty Latiolais, recently asked an interesting question regarding cascading LOVs: Say you've got two LOVs...STATES and CITIES. They both default to 'ALL' and 'ALL'. Since CITIES is dependent on STATES, as soon as STATES is changed, CITIES is blanked out. What should happen is that CITIES gets re-evaluated as in the following example... let's say STATES is ALL and CITIES is "Houston". If one then changes STATES to "Texas", CITIES should remain "Houston" as that is a valid value for CITIES. So basically, is it possible to maintain the selected value of an item if that same value exists in the list of values after refreshing? That's a great question! Thanks to new events in the APEX framework and Dynamic Actions the solution is far easier than it would have been in the past! Click here to see the demo but continue reading to learn how it all works… There are a three main events you need to be concerned with when it comes to cascading selects: change apexbeforerefresh apexafterrefresh The change event is a standard part of JavaScript and the DOM. This event fires when the user manually changes the value of the select list but can also be triggered programmatically via JavaScript. The apexbeforerefresh and apexafterrefresh events are custom events in the APEX framework. They fire just before and just after AJAX requests refresh something on the page. The events work with many items and regions that utilize this technology. In this example we have two select lists: parent and child. If you change the value of the child select list then the change event will fire and that's it. But if you change the value of the parent select list a lot more happens to the child select. Here are some of the highlights: The current LOV values are cleared out The apexbeforerefresh event is triggered An AJAX request brings back new values. This only happens if optimize refresh is set to false optimize refresh is set to true and

Schema on write This is the traditional approach for Business Intelligence. A model, often dimensional, is built as part of the design process. This model is an abstraction of the complexity of the underlying systems, put in business terms. The purpose of the model is to allow the business users to interrogate the data in a way they understand.
-
The model is instantiated through physical database tables and the date is loaded through an ETL (extract, transform and load) process that takes data from one or more source systems and transforms it to fit the model, then loads it into the model.
-
The key thing is that the model is determined before the data is finally written and the users are very much guided or driven by the model in how they query the data and what results they can get from the system. The designer must anticipate the queries and requests in advance of the user asking the questions.

You Probably Need Parallel Except When You Don't - 0 views

f you are running a large Oracle data warehouse you should be using parallel
-
Like all tools you have to use parallel correctly; no more would we think of using a wrench to hammer a nail then should you think parallel is the answer to all performance problems. Sometimes parallel will make things worse, sometimes parallel will make performance less predictable.
-
Parallel introduces additional work to a query, simplistically we need to: split the query into multiple parallel processes, execute them, wait for the processes to complete and finally coordinate the results. This all takes time to do. Our time saving comes from being able to process multiple smaller chunks of data simultaneously. If the time to execute the step in parallel is not significantly faster than doing it without parallel then the additional overhead may make parallel processing a slower option; this is typically the case with small tables where a full tablescan or an indexed access is fast. Use too few parallel processes and we will not gain much in performance, too many and we risk starving the database of resource for other work or even slow our own process as it waits for resource. If you have implemented some form of CPU resource management on your system you may find that you experience delays as your parallel slaves ‘wait their turn’

Summary: Check Search whole cells and uncheck Regular expressions
-
"Very important: Two of the options (OpenOffice.org > Preferences on a Mac, Tools > Options on other platforms) affect several functions, including VLOOKUP. Both of these options are in the Calc > Calculate section: Search criteria = and <> must apply to whole cells - If you uncheck this option text searches in VLOOKUP can match a substring of the values in the table so in the example a search for B will find B+. You almost certainly want to enable this option so that an exact match must occur. Enabling the option also makes your VLOOKUP formulas compatible with Excel. Enable regular expressions in formulas - Unless you understand what "regular expressions" are (see Help) and unless you specifically want to use them in your spreadsheet, you will want to uncheck Enable regular expressions in formulas because this option can make VLOOKUP difficult to use. Unchecking the option also makes your VLOOKUP formulas compatible with Excel. The questions below address what happens if you enable this option. Summary: Check Search whole cells and uncheck Regular expressions"

Why BI projects fail -- and how to succeed instead | InfoWorld - 0 views
-
A successful initiative starts with a good strategy, and a good strategy starts with identifying the business need.
-
The balanced scorecard is one popular methodology for linking strategy, technology, and performance management. Other methodologies, such as applied information economics, combine statistical analysis, portfolio theory, and decision science in order to help firms calculate the economic value of better information. Whether you use a published methodology or develop your own approach in-house, the important point is to make sure your BI activities are keyed to generating real business value, not merely creating pretty, but useless, dashboards and reports.

Next, ask: What data do we wish we had and how would that lead to different decisions? The answers to these questions form top-level requirements for any BI project.
