OLAP Datagrid

Hi All
This is quite a general question but I was wondering if
anyone was using the OLAP Datagrid in Flex 3.
Also, I was wondering if the OLAP calculations (data) within
the datagrid could be used to produce charts.
Any experiences would be worth hearing.
Best regards
Versie

How can I implement a datagrid like this

I would like to implement a datagid as the attached picture. This datagrid will have some money columns and I would like to summary of money at the last row. Just only the last row.
Thank you very much

Getting NaN in Olap Datagrid

Hi,
I am using the olapdatagrid and am using a date field as a
column axis. For the other axis I have an account hierarchy. For
the measure I am using a sum aggregator.
When aggregated the data contains 5 different dates. The
problem is that where an account contains values for only some of
the dates, the olapdatagrid displays NaN which looks as though
there is an error.
I would prefer it displayed 0 but a blank (as per the Excel
Pivot Control) would suffice.
Any suggestions.

OK, actually the answer is in the documentation. You can
apply a defaultCellString property to the datagrid. In this case I
am choosing the value "" to have the grid show a blank.

Suppressing the total row and column in OLAP datagrid

I have created an OLAPDatagrid and everything looks fine
except that I don't want to show the '(All)' row and column in the
grid. Is there a way to suppress them?
Thanks,
Fred

Instead of using members() in the query use children() for
the attribute/hierarchy.

Best way to implement DataGrid in JSP

Hi,
Can anyone please guide me as to what is the best way to implement a DataGrid in JSP ?
Thanks in advance.
-Sharada

Thanks James.
I guess I can use the JSP Datagrid taglib as well.
My main purpose is to have the functionality of updating the cells, resetting cells, ability to perform aggregate of rows and columns.
Also, I have another table which will have rows that are an aggregate of all the rows in above datagrid.
Please let me know if you have any other ideas.
Thanks,

Smooth scrolling in mx:Datagrid

Hi All,
I am implementing a datagrid in my extension for Illustrator CS5, 6. I want to have smooth scrolling in it as there are images that are displayed in the grid. I am using an ItemRenderer for displaying images. It has one column. I searched the net and came across this blog by Alex Harui.
This example is for List. I wanted it for datagrid. I overrode my datagrid scrollhandler and placed the code from the above example. Everything works fine except the up scroll. If I drag the scroll bar up/down, it works fine. If I scroll down by mouse clicks, it works fine. But, if I scroll up by mouse clicks, the scroll bar scrolls fine, but the grid view isn't updated. The grid view just repeats the images like in a loop. I am unable to understand.
Can anyone guide me?
Thanks!

I changed the item renderer to just include label. But still no change, the up scroll is just not working. Can anyone guide me here? I am stuck.
Thanks!

Item renderer in datagrid with actionscript

Hi
I want to implement a datagrid similar to the one given int
the starting flex examples but in actionscript. I am having a
problem with the itemRenderer. I can't figure it out how I cam
create a imagerender in a datagridcolumn.
My code is:
var dataG:DataGrid = new DataGrid();
dataG.dataProvider = xmlList;
var coluna:DataGridColumn = new DataGridColumn();
coluna.dataField="nome";
coluna.headerText="Title";
var coluna2:DataGridColumn = new DataGridColumn();
coluna2.dataField="thumbnail";
coluna2.headerText="Title";
var imagem:Image = new Image();
imagem.height = 75;
imagem.source = "../tb/"+instrumentos.thumbnail+".jpg";
//HERE RELIES MY PROBLEM -HOW TO ASSOCIATE AN IMAGE TO THE
ITEM RENDERER
coluna2.itemRenderer = new ClassFactory(imagem);
var lalala:Array = new Array();
lalala.push(coluna);
lalala.push(coluna2);
dataG.columns = lalala;
thanks in advance

ClassFactory takes a class, not an instance.
Try something like:
foo:ClassFactory = new ClassFactory(Image)
foo.properties= {height=75,
source:"../tb/"+instrumentos.thumbnail+".jpg"};
coluna2.itemRenderer = foo;
Note that using a ClassFactory this way will give you the
same image in
every renderer to start out with. However, I believe that
image
itemRenderers by default will take their source from the data
property when
that gets set.

In my jsp , I have implemented struts-datagrid and showing many rows at a time.
While scrolling the page , the column-names/header of the datagrid also scroll up and down and do not remain visible to the user.
Is there any way to fix the column-name/header on the top of datagrid?
Kindly suggest any solution.

Copy/paste full row, full column, a cell on datagrid using MVVM?

What is the best way to implement on datagrid? As I am new on this, I had some researches but I am confused because there are some complicated implementations and easy ones? I try to understand the best way.
Adding simply selection mode and selection Unit doesnt help. Because it only copies the row but I cant paste it simply as a new row.
SelectionMode="Extended" SelectionUnit="FullRow" >
this approach in the article looks old to me. Not sure if there is anything new and much easier with newest framework. I am using MVVM light in my project.
Attached is the sample project similar to my original project. can you please recommend me the best way for the following?
- Full Row(s) copy-paste
-1 or multiple columns copy-paste (optional)
- cell copy-paste

Datagrid with a datadriven combox

Hi,
I would like to implement a datagrid with a datadriven combox.
The database should store "only" values, but should show a different labeltext in the grid.
When the users load this Grid the stores values should be uses to set the comboboxes.
That sounds easy but I haven't found a easy way to implement that!
1.) I need to overrite the "save column" function of the generated code from FB4b1, so that the shown labeltext is not saved, but its db-values.
How can I do this?
2.) I need to build the combox in the datagrid, but there is nnothing like"combox.value="myValID" ( that would be all in vb.net)
Do I have to loop manually over the selectedIndex until I found my savedValue?
Like

Is there an easier way to do this?
Thanks for any pointers!

Hi Martin,
Couple of questions
Are you using LCDS as your backend?
Are you using the Adobe data modeler and deploying your model on to your LCDS server?
If so, then you could try something called derived properties, which actually do not require a database column and you could compute its value based on the value of a existing column.
You can find more info about this on

Each item in comobobox has a label and a data value associated with it.
The following should work if you were to access data of a selected combo box item, without looping through the items. If it is a string value then
mylabel.text = myCombo.selectedItem.data.toString() would show / store the associated data with the combobox item for the label text, you can replace mylabel with the datagrid's dataprovider for your requirements.
Hope this helps

OLAP Cache for Query Performance

Hi Experts,
I have below 2 Questions before we implement OLAP Cache for our Queries:
1) We have 15 imporatant queries - which do NOT have any variable/selection screen.
(question here is will it work for those kind of queries which dont have any selection screen/ variant ? ) --> client wants to prime the cache for few queries which dont have variable screen.
In this case, say if data is later filtered on any CHAR , will it take the data from Cache?
2) I have a query which initially will have few characteristics in the drill down when we first execute and users would be drilling down on many other characteristics after that. So if I want to fill OLAP cache for this query then what is the best way so that each drilldown in the query gets data from cache.
Thank you,
-Su

Hi Raghavendra,
Thanks for your response.
For first Question, Do you mean , even if we do not have any Selection varaibale on Query--we still can fill OLAP cache for it for its all values (i.e. No selection means "*") ?
If this is the case, then what we need to defile in General Precalculation (Variable assignment) while creating a new setting for the query.
Thanks,
-Su

Using Oracle OLAP

Our BI database is a pure star-schema (no snow-flake) and we use OWB to define it and load (ETL) from the source systems. We also define hand-coded materialized views for data aggregation.
Now we are thinking of using Oracle OLAP for:
- pre-aggregation
- forecasting analysis
- performance
Our db is small right now but we expect it to grow into terabytes.
- Would OLAP server system sit on top of our current BI or would we have to build it one time from the data in BI db and discard the contents of BI database later?
- From docs, it seems ROLAP is more suited for large dbs than MOLAP. With our db, would it be feasible for us to use MOLAP?
- Does ROLAP requires definining materialized view? If yes, how is it different than our current BI database?
- Can OLAP sit on our source database (OLTP db)? or does the source data come from a star schema?
As you can see, I am unable to understand what is the best way to implement OLAP server in our situation. Is there a "best practice" or "definitive guide" that I can refer to?
Any related info. is more than welcome.
Prashant.

Prashant, DW environments are generally organized into multiple areas, some of which you've identified:
1. Source systems which provide data for the data warehouse
2. The "data warehouse" itself - a central repository for all the transactions, etc. collected from the source systems. Main function is to STORE all of the data in a clean, consistent manner
3. Possibly multiple datamarts that organize the base DW data into specific subsets that are meaningful to the end users. Can be ROLAP, MOLAP, HOLAP, etc.
Each of these tiers has different goals, which usually means they need separate architectures and/or hardware:
1. Don't put BI systems on top of your OLTP system...if a user writes a run-away query, it can bring down your transaction processing systems.....
2. DW can either be in 3nf or dimensional form, but its main job is to capture the low level transactions and make sure they conform to standards (including data quality, etc.) Users SOMETIMES run queries directly against DW tables, but once the DW starts getting big (i.e. terabytes) you probably don't want users hitting directly against it
3. OLAP datamarts are almost always in dimensional form, but only contain subsets of data from the DW. These are designed to hit very specific business problems, and typically are at a much higher level of detail than the DW.
Hope this helps. DON'T PUT YOUR DW or BI cubes on the OLTP system!!!
