Mapviewer WMS and "dimension" data

Hi,
I have been using various WMS servers lately, and noticed that some of them support service metadata responses which include a "time" dimension. Does MapViewer support getting the available time values via a WMS getCapabilities?
Thanks
MH

Hi,
Current version of MapViewer doesn't support Time and SLD.

The Difference between "Cell Data" and "Dimension Data"?

What is the difference between the tab "Cell Data" and "Dimension Data" in SSAS?

Article quote: " SSAS provides the way to secure analysis services database/cube data from unauthorized access. Analysis services provides secure access by creating object called "roles". After creation of role, user's windows login credential can be used
to enroll into particular role because analysis services identifies user from their windows login credentials . You can protect your data in roles at two levels:
1) Dimension level
2) Cell level
If user has been assigned more than one role, analysis services loop through all assigned roles after login. Analysis services finds all permission level for the particular user and union all the permission levels.
If two roles has contradictory access for user then particular access will be allowed. Suppose role1 says Australia data access and role2 denies Australia data access then access to Australia data will be allowed. "

Mapviewer WMS and GetCapabilities

Hi,
We have a Mapviewer WMS server running well, but have noticed that when we use a WMS client to query the data (e.g. Quantum GIS, NASA WW) the WMS service returns the entire extent, not the extent of the data. This is really annoying and is an important part of WMS.
All the georasters we have are built correctly etc. (i.e. tested system known to work).
How do provide extents for just the data in the GetCapabilities?
Thanks,

I cannot find the user_sdo_view_metadata view. I do have:
user_sdo_geom_metadata
user_sdo_geor_sysdata
Yes, I would not expect the GetCapabilities spatial extent for all the images in the table, not just 1 image.
I used this query to check the spatial extents of each image and they are all there:
SELECT t.image.spatialextent FROM oblique t
Looking at the view in user_sdo_geom_metadata shows:
3 | oblique | image.spatialextent | <points showing diminfo> | 41103
which all looks good.
I noticed though for the user_sdo_geor_sysdata view, there is an entry for each image, for example:
9 | oblique | image | (null) | oblique_rdt | 1 | (null)
which means that for the meta_data_column_name it is set to null. Is that bad?

Can't view my Cube and Dimension Data with the Cube Viewer

I'm new in using OWB, i'm using Oracle 10g release1 with OWB R2 also Oracle WorkFlow 2.6.3.
When studying with the steps from the OTN pages (start01, flat-file02, relational-wh-03, etl-mappings, deployingobjects, loading-warehouse and bi-modeling)
the loading was success, i guess...
But when I want to see the data in the cube and dimension, an error occurs.
It says

How to get DIMENSION and CUBE data into JDeveloper???

i have build cube and dimension using oracle analytical workspace manager (AWM),
how i can get the cube and dimension data using jdeveloper 11gR2??
does anybody know?
any extension? or what??

The simplest thing is to use JDBC (java.sql package) to access the cube and dimension views through SQL. Something like this (with appropriate error handling).
String sql = "SELECT dim_key FROM product_view";
Statement statement = connection.createStatement();
ResultSet rs = statement.executeQuery(sql);
while (rs.next())
// Process row here
rs.close();
statement.close(); If your requirements are more complicated or you feel adventurous, then you can use the Java OLAP API. This is the code used by the data viewer in AWM. (Look for olap_api.jar in your database installation -- olap\api\lib\olap_api.jar my windows instance.)

Table as fact and dimension

Hi,
Can one table act as a fact in one subject area and act as a dimension in another subject area? Thanks.

Hi
I confirm Stijn Gabriels' post.
You don't have to do an alias in your physical table, otherwise the request will generate an alias in SQL for nothing ! However, in your logical layer, you will create 2 logical table : one for the fact, one for dimension. Both of them will have the same source : your unique physical table.
Let's take an example : suppose you have only 2 table in your datawarehouse : 1 fact table with degenerate dimension attributes (so a table with fact and dimension data), we'll call it "revenue", and 1 dimension table for... "Time", for example. We'll call it"Time"
Your conceptual (on paper) is a star schema with 1 fact table (revenue_fact), and 2 dimension table (time, and revenue_carac).
In your OBIEE physical layer :
- you import the 2 tables "revenue" and "time" from your database.
- you link "revenue" with "time"
In your OBIEE logical layer :
- you create a logical table called "Dim Time", based on the "Time" physical table and you do what you want with it (hierarchy...)
- you create a logical table called "Dim Revenue Carac", based on the "revenue" physical table, and you do what you want with attributes
- you create a logical table called "Fact revenue", based on the "revenue" physical table, and you do you what you want with measures and aggregation
- you link the 2 logical dimension table with the logical fact table
And that's all. Now, let's see which kind of SQL OBIEE will generate if you want to display the measure "revenue" with the attribute "revenue_carac" and the attribute "year".
Select Sum(R.revenue_measure) , R.revenue_carac , T.year
From revenue R , time T
Where R.time_id = T.id
Group by R.revenue_carac , T.year
If you set alias in your physical layer, the request will be that (and you don't want it) :
Select Sum(R1.revenue_measure) , R2.revenue_carac , T.year
From revenue R1, revenue R2 , time T
Where R1.time_id = T.id
And R1.id = R2.id
Group by R2.revenue_carac , T.year
same results, but useless join between the same physical table

Reg: Fact table and Dimension table in Data Warehousing -

Hi Experts,
I'm not exactly getting the difference between the criteria which decide how to create a Fact table and Dimension table.
This link http://stackoverflow.com/questions/9362854/database-fact-table-and-dimension-table states :
Fact table contains data that can be aggregate.
Measures are aggregated data expressions (e. Sum of costs, Count of calls, ...)
Dimension contains data that is use to generate groups and filters.
This's fine but how does one decide which columns to consider for Fact table and which columns for Dimension table?
Any help is much appreciated.
Pardon me if this's not the correct place for this question. My first question in the new forum.
Thanks and Regards,
Ranit Biswas

But my main doubt was - what is the criteria to differentiate between columns for Fact tables and Dimension tables? How can one decide upon the design?
Columns of a fact table will often be 'scalar' attributes of the 'fact' data item. A dimension table will often be 'compound' attributes of a 'fact'.
Consider employee information. The EMPLOYEE table can be a fact table. It might have scalar attribute columns such as: DATE_HIRED, STATUS, EMPLOYEE_ID, and so on.
Other related information that can't be specified as a single attribute value would often be stored in a 'dimension' table: ADDRESS, PHONE_NUMBER.
Each address requires several columns to define it: ADDRESS1, ADDRESS2, CITY, STATE, ZIP, COUNTRY. And an employee might have several addresses: WORK_ADDRESS, HOME_ADDRESS. That address info would be stored in a 'dimension' table and only the primary key value of the address record would be stored in the EMPLOYEE 'fact' table.
Same with PHONE_NUMBER. Several columns are required to define a phone number and each employee might have several of them. The dimension tables are used to help 'normalize' the data in the employee 'fact' table.
And that EMPLOYEE table might also be a DIMENSION table for other FACT tables. A DEVELOPER table might have an EMPLOYEE_ID column with a value that points to a 'dimension' row in the EMPLOYEE dimension table.

Percentage based on the Date and Dimension - WEBI

Hello,
I have to calculate percentage based on the Dates and a Dimension.
I have BEX Query as source and reporting is done on BOXI - WEBI
Here is the table structure in the report.
List# , Process01, Process02.
List# is unique and Process01-Has 4 operations, Process02 has 3 operations (and these Operations can change from 3 to 7 or 2).
Operations will have a 'Date' only when it is completed.
and when all the operations in a 'Process' have 'Date' then i need to get the 'Latest Date'. If few of the operations are not confirmed, then i need to get the percentage like when 2 of 4 operations have date it will be 50% and when no operation is confirmed then 0% and so on .
Example Cube data:
List#,ProcessCategory,Operation,Date
100,Process01,456,11/11/2010.
100,Process01,457,11/12/2010.
100,Process01,489,
100,Process01,490,
100,Process02,890,11/13/2010.
100,Process02,891,11/14/2010.
100,Proceess02,892,11/15/2010
Result:
List#, Process01, Process02
100,50%,11/15/2010.
Please help me in this, i tryed different logics but it is giving ERROR at percentage.
Your help would be appreciated!
Thanks in advance.

I applied this:
If([Process Category] InList("Process01") And IsNull([Date]);[Percentage];Max(Date)))
[Percentage] = (Count([Date])/Count([Operation]))*100.
but, this is not becoming true - even when Operation has one Date
Showing result as:
List#,Process01,Process02
100, 11/12/2010, 11/15/2010
But result should be
100,50%,11/15/2010
Can anyone help me achieve the right result!
Thanks in advance.

Difference between Data staging and Dimension Table ?

Difference between Data staging and Dimension Table ?

Data Staging:
Data extraction and transformation is done here.
Meaning that, if we have source data in flat file, we extract it and load into staging tables, we take care of nulls, we change datetime format etc.. and after such cleansing/transformation at then end, load it to Dim/Fact tables
Pros: Makes process simpler and easy and also we can keep track of data as we have data in staging
Cons: Staging tables need space hence need memory space
Dimension Table:
tables which describes/stores the attribute about specific objects
Below is star schema which has dimension storing information related to Product, Customer etc..

Modelling Time Dimension with Fact Table containing Start Date and End Date

Hi Gurus,
I have a time dimension with Year till Date. I have a fact table which consists of Start Date, End Date, Person ID, Department ID.
How do i design Time dimension with fact table the below scenario
In the dashboard i have start Month and End month as prompts.
In the report i need to display Count(Person ID) > Start Date and < End Date along the trend.
For instance, i have selected Jan-2009 as start date and Apr-2009 as End Date, then i need to display Count(Person ID) of Jan-2009, Feb2009, Mar-2009 andApr-2009.
I Can not connect Time dimension with only Start Date or only with End Date to get the trend along the months.
Please advice on the issue which i am having.

Hi,
Thanks for the response, Infact i tried using Complex join in physical layer. I have considered Time table joined with Fact table, and used >= and took and alias of the Time table and joined fact table using <=. When coming to BMM, i am not knowing how do i design this as if i merge the both the time dimensiona and its alias into single table, values will not be correct and if i make them as seperate columns. i can not show the trend as both are different columns.
Can you please let know where i am going wrong.
Thanks

Oracle Data Compression on SID tables and Dimension Tables

Hello Community,
We have had great success with Oracle compression on ODS tables that are no longer loaded.
We'd now like to move on to other types of BW tables that are very large.
OSS Note 701235 provides answers to questions concerning the possible use of Oracle compression together with SAP BW.
But the Note does not give suggestions for (or against) Oracle compression on SID tables or Dimension tables.
I believe both table types would exhibit the same behaviour : mostly inserts of new SID IDs and new DIM IDs, but few updates to existing SID or Dimension records. If this is true, then both are good candidates for oracle compression.
Do you also agree that this is the typical behaviour for SID tables and dimension tables ? And that these types of tables are good candidates for Oracle compression in a large BW system ?
Thanks kindly!

Hi all,
Although this is an old thread I stumbled on during my own investigations I can provide some answers to your questions.
Table candidates for compression are found by these criteria
       - Table size big enough?
       - Long lifetime of object planned ?
      - No or only rare structural changes for the table   ?
      - u201EUpdateu201C rate low : is your data mostly kind of u201Cread onlyu201D ?
--               for the wideley used rolling window partition techniques of
                  tables in BW this is not a problem: mostly INSERTu2019s in the
                 current partition not affecting other partitions
BW tables that can benefit from compression (see SAP notes 105047,701235)
       - PSA tables with data that must be saved for a longer time
       - ODS change log (no Updates of old data, only Inserts of new data)
       - u201Ehistoricalu201C cubes wich get no changes in table structure anymore
Limitations
         - normal Insert or Update statements are stored ALWAYS in uncompressed
                format and must be compressed separately ( <= Oracle10g )
         - Slight CPU overhead of compression, butu2026
         --      CPU consumption is more than compensated by doing less I/O as
               for Bulk loads or parallel processing
         --      SAP BW transformations took a significant amount of CPU for
                   overall load-time into cubes caused by the application server not
                   the database
          - Table must have not more than 255 fields
          - Adding columns with an initial value or dropping columns require
               uncompression of the complete table (strongest limitation)
Consider all this above and you can decide that tables that going through UPDATE's are
not good candidates for compression or tables that can change it's structure (like
Fact- or DIM tables) .
Now, my questions to you:
Wich Oracle version do you use?
Wich tool do you use for Oracle compression?
BRspace (can you give an example ?)
ALTER ... MOVE COMPRESS

Creating scenario dimension and loading data

Hi all,
We have two fact tables. The first one is sales that include quantity and subtotal columns. The other one is budget that include quantity and subtotal. We are working with hyperion essbase 9.3. First of all we are creating two model. For sales model we create 7 dimensions (product, chanell, time, company, currency, customer, account) and 3 attribute dimension and for budget model we create 4 dimensions (account,company,customer,product) in metaoutline. And we create 2 application for each metaoutline. We plan to report sales vs budget but we don't know how to join sales and budget data. Everybody recommends scenario dimension. we don't know how to create sceneraio dimension and in which application Essbase integration or Essbase administration services.
thank you.

I agree with Cameron. The best way is to put them into one cube. Since you are using a SQL source you can manulate it to have your budget load to the same time level as your actuals. For example suppose you load actuals daily and Budget is Monthly. for consistancy, you could load the budget data into the 15th day of the month. At the Monthly level where you would compare budget to actual, the numbers will be correct. Loading into dummy members for the dimensions that don't exist for budget is a common practice when trying to sync up data. If you really want to make it easy, you could union a view to make it look like you have a single fact table (based on the combo of budget and actual) and have a single metadata outline to load everything. I prefer having two because of different load requirements, but this is an option.
If you don't want to go this way, the next option is to partition your budget data into the actuals cube. this would keep them seperate but allow you to see them togeter. Between the two option, I prefer the single cube approach better

Can we connect Mapview to multidimensional database and retrieve data

I have zero knowledge on MapViewer and hence I am curious to know, if we can connect MapViewer to multidimensional database(Like Essbase etc...) and retrieve data from them ???

Currently, MapViewer needs a conection to an Oracle Database where MapViewer metadata is stored. You may be able to access external spatial data if there is a java implementation of an interface to access external native data. MapViewer provides a spatial provider implementation for shapefiles. For other data, including from external databases, you may be able to access them if a java class implements the spatial provider interface class. Mapviewer Users Guide has some notes about implementing a external spatial provider.

Mapviewer caching on WMS and WFS

Does the tile cache do any good for WMS?
e.g.: only same result for same parameters like simple HTTP caching?
or can it do nice things like assembling cached tiles as required?
What about WFS caching? I assume every requests hits the database. Since moving the query window 5m to the left ... :-)
---

Just to be clear then, if someone is accessing my MapViewer instance using WMS i.e they are sending requests such as
http://host:7001/mapviewer/wms?REQUEST=GetMap&LAYERS=...
MapViewer does not cache these and will generate the map each time (even for identical consecutive requests). Is this correct?
