OLTP Vs OLAP (Data Warehouse) As A DataSource In Analysis Services 2005
Jul 3, 2007
Hello,
Can I import an OLTP (Reltional DB) as a Data Source into SQL Server
Analysis Services 2005 and then use the Cube Wizard and the new Data
Source View feature to create the OLAP model ?
Or do I have to first design an OLAP Data Warehouse with a Star Schema
and then import this DW as a Data Source into my Analysis Services
Project.
With SQL Server 2000 , OLAP would be the way to go..but with SQL
Server 2005 , it seems as though the wizard and data source view
features do half the work for you.
I have an OLTP DB and am not sure which route I should take ! Any
suggestions / input would be much appreciated.
We have a live OLTP database for which we create full backups every week and differential backups every day. Recently we added an OLAP database, which we need to update daily with changes from the live database.
This is the process we are planning to use. 1. Restore last full OLTP backup. 2. Apply the last differential OLTP backup. At this point we should have a replica of the live OLTP database. 3. Update OLAP database based on the OLTP replica database. 4. Delete the OLTP replica database.
Two questions. 1. If different from the process above, how is this OLTP-to-OLAP transformation typically done in the industry? 2. What is the best way to implement this process with SQL Server 2005?
hi I am new at MSSQL 2000 DBA thing. and trying to learn more about analysis service/data warehouse/data mining. so is any expert out there can Recommend some good books or web link article to read? Thanks
I have created database and OLAP cube in Analysis services using SSAS.In SSAS I have used a datasource which is using SQL tables to populate OLAP cube.Now when I added some more data to my SQL tables and trying to deploy cube,the newly added is not getting populated in the cube.So i want run SSIS package which will import data from SQL tables to this OLAP cube.
Can you please help me how to write this SSIS package to import data from SQL tables to OLAP cube.(Very urgent issue)
How must I change the mdx that is generated for the available values for a user parameter in order to get the content sorted?
Regards,
Henk
BTW the exact mdx query is given below (and the label field of the parameter is set to 'ParameterCaption'), but I would already appreciate an example of a simple mdx.
MEMBER [Measures].[ParameterCaption] AS '[Organisatie].[Level 5 naam].CURRENTMEMBER.MEMBER_CAPTION'
MEMBER [Measures].[Nummer en Naam] AS '[Organisatie].[Kosten Nummer].CURRENTMEMBER.MEMBER_CAPTION +": "+ [Organisatie].[Level 5 naam].CURRENTMEMBER.MEMBER_CAPTION'
--MEMBER [Measures].[ParameterValue] AS '[Organisatie].[Level 5 naam].CURRENTMEMBER.UNIQUENAME'
MEMBER [Measures].[ParameterLevel] AS '[Organisatie].[Level 5 naam].CURRENTMEMBER.LEVEL.ORDINAL'
SELECT {[Measures].[ParameterCaption],
[Measures].[Nummer en Naam]
, [Measures].[ParameterValue], [Measures].[ParameterLevel]} ON COLUMNS
, filter ([Organisatie].[Level 5 naam].MEMBERS,[Measures]) ON 1 ,
[Organisatie].[Kosten Nummer] on 2
FROM ( SELECT ( STRTOSET(@OrganisatieLevelnaam, CONSTRAINED) ) ON COLUMNS FROM ( SELECT ( STRTOSET(@KalenderFactuurPeriode, CONSTRAINED) ) ON COLUMNS FROM ( SELECT ( STRTOSET(@KalenderFactuurJaarNummerLang, CONSTRAINED) ) ON COLUMNS FROM [FMR DWH Afgenomen Dienst])))
Can somebody on the SSRS product team double check me that I've written that up right? That seems like a pretty important change and I can't see it mentioned in BOL anywhere.
1. SQL Server Data Warehouse 2. OLAP CUBE in Analysis Services
My question is - If my SQL Server Data Warehouse is changed (Having Append Data) - Is that My OLAP Cube will have the Append Data?
It's possible, my OLAP Cube always having Append Data if my Data Warehouse is changed? If yes, how to do it without re-deploy and re-process my Analysis Services Project.
1. As per my current development SQL Sever Analysis Database consists of two Cube (Cube A and Cube B). Cube A and Cube B share the same data source view (DSV1). The source for both these cubes has the same data source (DS1).
2. As per the requirement I need to create third Cube i.e. Cube C. Is it possible to create a second Data Source View (DSV2). The Source of second Data Source View (DSV2) will be the same data source(DS1).
I am thinking to create second Data Source View (DSV2) for Cube C because existing layout of the DSV1 has become complex. I wanted to know the pros and cons of creating a multiple data source view with same data source
A rather dumb question but I've installed an evaluation copy of SQL 2005 on my machine and a colleague would like the Analysis Services Data Mining capability on his machine (without the eval SQL Server).
Is there a license associated with such an installation when we buy 2005 or does it fall under client components which can be installed on any number of users machines?
I have some questions about SQL Servers 2000 and 2005 compatibility. In my configuration I have to use both servers. The cubes are stocked in 2005 server. May I transfer from 2005 to 2000 Analysis Services the cubes?
If yes, what is the procedure? The result of migration is the same in the two different versions?
I am using sql server 2005 standard edition and i have installed MSXML core services 6 and also ADOMD.net for analysis services. i am using visual studio 2005 version of 8.0.5072742 and the problem that i am facing is when i use to develop reports using Analysis services as a data source , the error message pops up and VS 2005 gets crashed.
i could define the dataset , layout part and when i prees the preview , it gets crashed. could any one help me on this problem to sort out.
I have been looking at implementing a tabular model based on an OLTP database that's not dimensional. I know that this is possible but during my proof of concept I have encountered numerous problems ...
The things that I have run into are: After setting up the relationships I have found that measures filter context don't propagate along the relationships as I would expect. if the measure is coming from a target table and not a source then an ALL member is returned ( as in multi dimensional when a dimension isn't related to a measure group). Given the lay out of an OLTP database this will be hard to avoid.
One thing I have done to try an mitigate the above problem is to combine the tables used for measures in a view and using that in the source to connect to the rest of the tables. however due to the tables being of different grains this has then created duplication in some of the keys and measures. so the keys cant be used in relationships and the measures aren't accurate.
Are these things other people have come across? or should I give up the ghost and just recommend using dimensional models for the source? is tabular just geared towards a DW the same as multidimensional?
Our OLAP environment involves an ETL/Data Warehouse/Data Mart server and a cube publisher server. We would like to learn how to automate the Archival/Restore of OLAP databases. We are currently doing it manually though OLAP Manager. Any help would be appreciated. Thanks. James.

I would like to know if Reporting Services 2005 is a good tool for making reporting activities on SQL Server 2005 DW and also using OLAP (Analysis Services 2005).
I am new to both Reporting Services and Webservices implementation so I am just trying to use a simple example. I found a Webservice on the internet that returns movie information:
Hello, I have a problem when trying to fully process an SSAS database using Integration Services "Analysis Services Processing Task" task. I have 2 of these tasks which are responsible for processing the Dimensions then the Cubes. When I run the package either via the BIDS environment or on the local server from the Integration Services engine, I will get an error after about 20 minutes stating:
"Error: Memory Error: Allocation failure. Not enough storage is available to process this command""Error: Errors in the metadata manager. An error occurred when loading the <cube name> cube from the file \?D:Program FilesMicrosoft SQL ServerMSSQL.2OLAPDataMyWarehouse<cube file>.xml"
The cube name is not specific, it will fail and any of my cubes could be in the error log
If I fully process the AS database using the AS engine (logon to local AS server, right-click AS database and click Process), I get no errors at all, it processes and completes fine. The processing options are identical when I run in AS or via the SSIS "Analysis Services Processing Task" task.
I've searched quite a lot online but no joy, the information I have gleaned from various sites does not directly link SSIS with SSAS processing problems.
When either the AS processing starts via SSAS or SSIS the memory usage of MSMDSRV.exe increases to around 1.4 / 1.5 GB but never goes to 2GB ever, even when the error appears.
I've done the following with no effect.
" Have run via AS and works fine " No specific cube it fails on " Have created a Dimension only package, same problem " Changed the maxmemorylimit " Changed the connections to localhost " Memory DOES NOT max out on server
Server Specs: Windows Server 2003 Standard + Service Pack 2 4GM ram, 2GB paging file
I'm trying to create reports in RS2005 using AS2000 as my data source. I understand that if I use RS2005 on AS2000, I wont be able to enjoy the OLAP based parameters as in using AS2005. Does anyone know an easy way to easily use Parameters in RS2005 while still using AS2000?
i have a small problem with the data sources in the reporting services, maybe you can clarify the situation... I have a MS CRM 3 solution with the reporting services 2005 installed. From an other vendor we have a arcplan solution on the 2000 analysis services. I would like to get access from the 2005 reporting services to the 2000 cube. Is this possible? Ive read that the SSMS cant connect to the 2000 cubes. Can i connect from the reporting services??
I have a .rdl file that was exported out of ProClarity's Desktop Professional 6.1 using their RS plug-in. I uploaded the file into Report Manager and when I execute it, I get the following error:
An error has occurred during report processing.
Query execution failed for data set 'Three_Month_Funding_Trend'. Unable to recognize the requested property ID 'ReturnCellProperties'.
Does anyone have any idea what this is referring to? Does it have something to do with my configuration, connection or the report definition? Other reports such as DBMS based reports work fine.
I am new to SQL Server and not quite understand the difference between OLAP server or SQL Analysis Service. Are they referring to the same thing?? An user asked me to confirm that the OLAP server is active on a server running SQL Server 2005, what do I need to check. The Analysis service is up and running, does it mean it is OK??
I want to connect MS SQL 2000 Server with Crystal Analysis via OLAP.
I have installed SQL with Windows authentication mode and installed crystal Analysis 9.0
I have configured Crystal OLAP connection setup.
When I am trying to open or create new application through CA I am not getting through OLAP connection with SQL and I am receiving the error as the following.
Error 1
" Unknown User name and bad password."
Error 2
Failes to initialize.( Cannot connect to the server 'XXXX." the server is not started or too busy)
I have SQL 2005 SP1 already installed and I am trying simply to add Analysis Services in without screwing anything up.
I re-run setup from the original CD, but then I receive the following warning:
To change an existing instance of Microsoft SQL Server 2005 to a different edition of SQL Server 2005, you must run SQL Server 2005 Setup from the command prompt and include the SKUUPGRADE=1 parameter.
Can I safely continue with the installation and just check Analysis Services since it is just a warning? And after the install re-run SQL 2005 SP1 or is there a way to add this from the SP1 installation files, please help.
I have been geting an error every once in a while shown below:
OLE DB error: OLE DB or ODBC error: [DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.; 08S01.
I look at other messages here and found people that say it is a network communication problem, but I am runing Analysis Services and SQL 2005 on the same box. Can anyone help with this?
