Does Microsoft plan to extend the number of Data Mining algorithms in AS in the future releases? The question is motivated by the task of so called "link analysis" where one should determine how data attributes are related to each other or how and in what extent they influence each other in probabilistic terms. A good solution would be to build a Bayesian Network which gives an insight to how data attributes are related by means of directed acyclic graph. But this approach is not yet implemented in AS2005.
Existing algorithms such as association rules or decision trees might be used but they are far from being ideal for this task (association rules are designed for determining frequent boolean sets in data like Name=Attribute, decision trees work good for classification tasks but perform poor by design for the tasks of revealing attributes direct and inderect influence).
It would be interesting to know what algorithms and approaches Microsoft plans to develop in the future.
I have created an Access2003 project (existing data) that links to external data. First I connected to a SQL Server 2000 database. Success. Then I tried to set up a Transact SQL data connection to a legacy MDW-secured Access97 database. (A third-party VB6 application goes against it, and we don't have the source code, so we cannot upgrade it.)
The Transact SQL link tests OK but I cannot select any of the tables or queries from the list presented. However, with the same credentials, I can use these same objects in Excel 2003.
When setting up the link in Access2003, I specify JET 4.0 OLE DB Provider, I enter the MDW file on the All tab, a username and a password on the Connection tab where I browse to the MDB file, and specify Shared Deny None on the Advanced tab. When I test the connection, it tests OK ("Test connection succeeded"). Yet on the "Select the Database and Table/Cube which contains the data you want" dialog, "(Default)" appears in the grayed-out dropdown. Then, beneath that dropdown, there is a grid with Name and Description columns. The grid contains query names but the grid is not enabled. The list of queries is this table is grayed out. Neither of the scrollbars works.
BUT... if I use the SAME username and password in Excel2003, and specify the same MDW, there is no problem working with these same database objects in the legacy Access97 database. WHAT IS DIFFERENT ABOUT THE WIZARD IN EXCEL THAT ALLOWS IT TO SUCCEED AND THE WIZARD IN ACCESS THAT CAUSES IT TO FAIL HERE? In Excel, the list of available providers says Microsoft Access Driver, not JET 4.0 OLE DB Provider.
When trying to link to an SQL table in Access 2003, the software appears to be malfunctioning.
The sequence of events is File - Get External Data - Link Tables - Files of Type: ODBC Databases().
The Problem: On two of my computers, the select data source window does not pop up, preventing me from linking to any ODBC data source.
Observations: This function has worked normally in the recent past and works on other computers running Access 2003. One difference between the computers working and non-working computers is Norton Antivirus 2006 (recent upgrade).
Has anyone experienced anything like this? What's going on?
I have, a SSAS 2012 tabular instance with SP2, there is a database on the instance with a read role with everyone assigned permissions. When configuring the Power BI analysis services connector, at the point where you enter Friendly Name, Description and Friendly error message, when you click next I receive the error "The remote server returned an error (403)." I've tested connecting to the database from Excel on a desktop and connect fine.I don't use a "onmicrosoft" account so don't have that problem to deal with.
We use Power BI Pro with our Office 365. As far as I can tell that part is working ok as I pass that stage of the configuration with a message saying connected to Power BI.The connector is installed on the same server as tabular services, its a Win2012 Standard server. The tabular instance is running a domain account that is the admin account for the instance (this is a dev environment) that account is what I've used in the connector configuration. It's also a local admin account. There is no gateway installed on the server.
I have a cube that we are processing nightly via an Analysis Service Processing Task in SSIS. In order to increase the performance of the processing time, we elected to use a lot of rigid dimension attributes, and do a full process of everything in the SSIS task. The issue that I am having is that after that task completes, I need to go into Visual Studio to deploy the cube becuase we are unable to browse or use the cube. This issue seemed to start once we changed the SSIS Analysis Service Processing Task to do a full process on the dimensions, rather than an incremental.
I would expect that once development is done, and it is processed and deployed, that is it. My thinking is that the SSIS task should just update the already deployed cube,
How to right choose key column in"Mining Structure" for Microsoft Analysis Services?
I have table:
"Incoming goods"
Create table Income ( ID int not null identity(1, 1) [Date] datetime not null, GoodID int not null, PriceDeliver decimal(18, 2) not null, PriceSalse decimal(18, 2) not null, CONSTRAINT PK_ Income PRIMARY KEY CLUSTERED (ID), CONSTRAINT FK_IncomeGood foreign key (GoodID) references dbo.Goods ( ID ) )
I'm trying to build a relationship(regression) between “Price Sale” from Good and “Price Deliver”.But I do not know what column better choose as “key column”: ID or GoodID ?
I am connecting to SSAS cube from Excel and I have date dimension with 4 fields (I have others but I don't use it for this case). I created 4 fields in order to test all possible scenarios that I could think of:
DateKey: - Type: System.Integer - Value: yyyyMMdd Date: - Type: System.DateTime DateStr0: - Type: System.String - Value: dd/MM/yyyy (note: I am not using US culture) - Example: 01/11/2015 DateStr1: - Type: System.String - Value: %d/%M/yyyy (note: I am not using US culture) - Example: 1/11/2015
Filtering on date is working fine:
Initially, in excel, filtering on date was not working. But after changing dimensional type to time, and setting DataType to Date, as mentioned in [URL] filter is working fine as you can see in the picture.Grouping on date is not working:
I have hierarchy in my Date dimension and I can group based on hierarchy, no problem. But user is used to pre-build grouping function of excel, and he wants to use that. Pre-build functions of Excel, Group and ungroup seems to be available as you can see in following picture:
But when user clicks 'Group', excel groups it as if it is a string, and that is the problem. User wants to group using pre-build grouping function available in Pivot table. I also find out that Power Pivot Table does not support this excel grouping functionality. And if I understood well, this pre-build grouping functionality of excel, needs to do calculation at run time, and that is not viable solution if you have millions of rows. So Power pivot table does not support pre-build grouping functionality of excel and hence we need to use dimension hierarchy to do the grouping. But I am not using Power Pivot table, I am using simple Pivot Table. So I expect grouping functionality to be working fine. Then I tried to do simple test. I created a simple data source in excel itself. And use it as source of my Pivot table. Then grouping is working fine. The only difference that I can see is (When double click the Measure value in Excel),For date values of my simple test, excel consider them as 'Date'.
For date values of my data coming from cube, excel consider them as 'General'
2.1. But value here is same as it was in simple test.
2.2. 'Date Filter' works just fine.
2.3. If I just select this cell and unselect it, then excel change type to 'Date' though for that cell.
2.4. I have created 4 different types of fields in my date dimension thinking that values of attribute of my dimension might be the problem, but excel consider 'General' for all of them.
2.5 This value (that can be seen when double clicking on measure) comes from 'Name Column' of the attribute. And the DataType defined is WChar. And I thought that might be the reason of issue. And I changed it to 'Date'. But SSAS does not allow it to change to 'Date' giving error : The 'Date' data type is not allowed for the 'NameColumn' property; 'WChar' should be used.
So, I don't know, what is the puzzle piece that I am missing.
1. Date filter works, group does not work
2. Excel consider it as 'General' string.
3. SSAS does not allow to change 'NameColumn' to Date.
I would like to know the best practice for running analysis service in terms of port usage. Is it better to run on a specific port or have dynamic ports ? We have clustered servers that run default on 2383 but not sure with non clustered what's the best way to get performance.
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?
Hi all,I'd like to know what the best means available is to enable distributedqueries from a SQL Server 2000, on tables in BOTH SQL Server 2000 and aremote DB2 server (the latter is not yet available for testing).So, I would be wanting to write queries or SP's like:select t1.field1, t1.field5, t1.field6, t2.field55, t2.field22from MySQLServer.mydb.dbowner.tableXXX as t1inner join ThatDB2Server.thatdb.thatowner.tableYYY as t2 on t2.field11= t1.field99where t1.field44 = @foobarI'm aware of at least two ways to go here:1) in SQL Server 2000, create a linked server to the remote DB2server, either using the wizard or sp_addlinkedserver, and using eitheran OLEDB or ODBC connection;2) using MS Host Integration Server (HIS).Since I've only just today learnt about HIS, I don't know very muchabout it.Questions:(a) are options (1) and (2) mutually exclusive, or does one depend onthe other?(b) can I do (1) without having to bother with (2)? If this, wherewould I get hold of the required OLEDB/ODBC Provider?(c) Is there another way(s) to go about this task?HYCH,Rob
There is a way to create a link from a SQL Server database to a table located on a MSAccess database? I mean like creating links from MSAccess to other databases. The requested table is updated many times/day, and I dont want to import the table each time an update happens. Thanks, Richard
hello all I have a web application(asp.net) and Database(sql server 2005) . we have installed them on several servers. now we want to have a connection between apllication on one server to a database on another server . for example we have Server(A) and Server(B) the DataBases and Web apllications on two server are the same. sometimes the Apllication on server(A) must connect to database on server(B). whats the solution plz? note that the number of servers can be inceased in the future this mean the number of servers are not fixed. thanks
Can any one tell me what I did wrong? Tried to set up link server from SQL 7.0 to Oracle.I did it as it was instruct in BOL. When I tried to click on the table, I got this message "error 7399: OLE DB provider "MSDAORA" reported error. Thanks.
I have created a linked server using an userid that have access to 2 different databases. The linked was created successfully but I am only able to see tables in 1 database but not both. The tables of the databases that I can access is the default database of that userid. Is there a way to see all the tables from more than 1 database that the user is authorized to? Thanks.
I am working from within an SQL database trying to get data from an MS Access Database as a linked server. I can "successfully" add the linked server, but when I try to open it from SQL EM I get "Error 7399. . . " from Microsoft Jet. When I try to query it from QA I get "Could not initialize data source object of OLE DB provider 'Microsoft.Jet.OLEDB.4.0'. [OLE/DB provider returned message: Not a valid account name or password.]"
I tried both Access 2000 databases and '97. Same results for each. Big project pending . . . any help is appreciated!
Is it possible to use database links on MS SQL-Server 2000, like on Oracle? If its possibe, what is the syntax and can i create a database link from Microsoft SQL Server 2000 to Oracle?
I have 2 servers A and B DB1 is the database in A and DB2 is the database in B
want to fetch the records from the server B in DB2. My query is
select * from B.DB2.dbo.table1
when i issued this statement in server A from database DB1 got the following error... OLE DB provider "SQLNCLI" for linked server "B" returned message "Communication link failure". Msg 10054, Level 16, State 1, Line 0 TCP Provider: An existing connection was forcibly closed by the remote host. Msg 18456, Level 14, State 1, Line 0 Login failed for user 'sa'.
How to solve this issue.
(Note - login for SERVER A - sa/<nopassword> login for SERVER B - sa/master)
I just reinstalled SQLExpress and all the dbs that I created are no more linked. The files still exist in the folder where the current version stores dbs (...Microsoft SQL ServerMSSQL.1MSSQLData) but they are not "linked" (don't know the right term).
Is there anybody who could help me how to "relink" these dbs to the actual .SQLExpress instance?
Hi all, I am having a problem in sql2000. I am having two databases.One is having all the tables. Another one is having the stored procedures. I ve to use the tables in first one in my stored procedure with out using fully qualified Name.
I work extensively with Access; I have a new project with very large tables (as many as 15 million records). Is it worth my while to link Access to SQL Express if both are on the same machine?
I've downloaded SQL Express and installed it, but it won't let me link to Access 2003. Is there an update or patch to Access 2003 that will make this work?
If I do make the link successfully, will it be transparent - that is, can I work in Access as I always have, or would I have to learn how to create databases and queries in SQL? (I do know that I can make tables in Access and migrate them to SQL Server).
Where would I find simple step-by-step instructions to do this - my interest is more in the substance of my data analysis than in programming per se.
Hi All may be my post sounds stupid but i have on idea about it.
can some one there please clear what is relationship between MDAC and SQL Server. id MDAC part of SQL Server or it is optional tool for some thing else. what it is excatly and links to useful tutorial etc.
Hi, Im using SQL server.I need to get a table from a database in oracle server from my friend. She sent me the database by exporting. But the contents in the database will not be updated if she updated her databse right. What to do if I want the database that she sent me to be updated each time she updates her database? Help me.
I am working on a databse on my local box, my source data is onanother. How can I link the database and table from one server toanother? Currently I am using DTS to just transfer the records!
If I bring up a report in the report server (http://reportserver/Reports/Pages/.... and I set the parameters to see the information I want to see and say to myself, hey, my boss would really like to see this, how would I go about sending him the link to the report with the parameters already set. Ideally when I view the report, the parameters would show in the URL automatically as other reporting products do, however, SSRS does not provide this. I do not even see a function in the report designer to display the link on the report itself so I can cut and paste from it. Anyone know how to do this without having to custom craft a URL or set a one time subscription?
