Replication :: Data Belonging To Specific Warehouse Replicated To Its Corresponding DB
Jul 10, 2015
We have a master database (SQL 2014 Std) from which data are imported from XML files (send by en ERP system) using SSIS. Â There is about 12 other servers (SQL 2014 Express) located in remote warehouses. People will uses PocketPC to scan barcode of products in the warehouses and all operations must be forwarded to the master DB to be exported in a XML file for the ERP system.Now, each warehouses are independant. How can I setup the replication so only data belonging to a specific warehouse is replicated to its corresponding DB? I thought about creating views, one for each warehouses, and setup a replication for each warehouse, so there would be 12 merge replications configured. Is it fine?

Hi all,we are developing an internal application that involves "Timesheets","Support" and "Project Management".Imagine that there are 3 different databases for the above scenario,under SQL Server 2000.My task is to create one or a few table triggers forINSERT/UPDATE/DELETE operations. For example:- if a row is added in Table A of "Timesheets" database, then Table Bof "Project Management" needs to be updated.The concept is clear i think. The question is how we do the above.Note that I am a new progremmer to SQL Server (I have been dealingwith Oracle so far), and I don't know how we programmatically connectto different database within a trigger, how do we check thepriviledges etc.Can someone help me?ThanksChristos Andronicou

Using SQL 2005 SP2. I have a publication that contains indexed views, and some other objects that query the indexed view using WITH (NOEXPAND). Currently replication fails because the CLUSTERED INDEX on the view is NOT replicated. I've experimented with various schema options but nothing changes. The view is replicated but not the clustered index on that view. I've seen some discussion on replicating indexed views to a table, but I would like to replicate indexed view schema fully. (Including the clustered index on that view). Is there a way to make this work?

I'm a novice with replication and am in need of direction on how to restore replicated databases. Server A replicates 5 databases to server B using transactional replication. Server A also contains the distribution database. I'm perfoming PUSH replication.
The development area asked me to restore Server A with a copy of production data located on server C. After I restored the data from C to A, I noticed that server A was no longer published. Is this normal?
I re-published the 5 databases, but noticed that the Log Reader Agent has now been running for 2 hours. I'm trying to give myself a crash course in replication, but am coming up empty regarding (1) the prefered method for restoring replicated databases and (2) determining why the Log Reader Agent is taking so long.
Any suggestions?
Thanks, Dave

For SQL 2005 transactional replication I have 1400 articles (tables, views, functions, sp) that are all replicated.
Will SQL 2005 allow me to drop a table from from the publication and drop it from the publication database that is referenced by exising views or sps that are replicated or does it somehow check that?

I have 1 sql server 2005 database in Server A that is publishing a table to another database in Server B using the transactional method.
It is possible for me to delete all the rows in the database located at the publisher at the same time the subscriber pulls them?
Thanks.

I have Snapshot set up as a schedule task between server A and server B.
If I make changes to the db schema on server A - the changes are not replicated to server B.
Is this normal?
Do I have to restart the Sanapshot agent each time there is a schema change?
Thanks,
Bianca

We had an issue recently where a (transactional) replicated table was replicating data as expected.
Then about 30 or so rows in the source table were not in the destination table, but other rows created after those 30 rows were replicated.
We have pretty much confirmed that users did not delete those rows.
Unfortunately we had to resolve the issue quickly and so blew away & recreated the subscription so a lot of evidence is probably gone from the crime scene.
We cant figure out what could cause 30 rows not to be replicated, yet leave replication operational.

I have a requirement to implement CDC for 50+ tables to implement incremental data changes warehouse/reporting rather than exporting the whole table data. The largest table is having more than half a billion records.
The warehouse use a daily copy of OLTP db (daily DB refresh). How can I accomplish this. Is there a downside in implementing CDC just for the sake of taking incremental changes on the tables?
Is there any performance impact if we enable CDC on OLTP db?
Can we make use of the CDC tables on the environment we do daily db refresh so that the queries don't hit OLTP database?
What is the best way to implement CDC to take incremental changes for reporting.

Hi Dear All!
I am Crystal Reports Developer and I am new in SSIS environment. I have started to read Professional SQL Server 2005 IS book. I am really confused by many tasks to choose.
I need to develop reports from data warehouse. But before I have to send the data from operational database (SQL Server 2000) to warehouse (SQL Server 2005) monthly - I have a script for retrieving the data. For my package, I chose Data Flow Task, Execute SQL Task, and OLE DB Destination, and it does not work.
Please help me if I can look similar packages performing?
Thank you!!

We have a "main" SQL 2014 server who imports XML files using SSIS in a datacenter. In remote sites (which are warehouses), there is an instance of SQL 2014 Express. A merge replication is setup, as every operations done on each site must be "forwared" to the main database, as some XML files are generated as output for an ERP system.
Now, the merge replication replicate all the data to the server on each sites. But a specific site don't need the data of every other sites, only the data relevant to itself (which is the warehouse code). Is there a way to replicate only the data relevant to each individual sites to the subscribers? Or is there a better way than replication to accomplish this?

I need a recommendation on a data modeling tool that can be used with a data warehouse. My warehouse is running SQL 2012.
Here is my challenge: Most of the tables in the warehouse do not have primary keys and none of the tables have foreign keys on them. However, there are indexes and unique keys/indexes on the tables. I am looking for a tool that I can create virtual relationships on how the data is related, so it is visually easier for the ETL developers to write the code.
I have looked at both ER/Studio 11 and ERwin 9.6. Neither of them do it exactly the way I want it too. However, ER/Studio is pretty close.

I am working on to create a data warehouse. I have made a database which will be the data warehouse and will consist of dimension and fact tables. I know that other than dimension and fact table a data warehouse should also consist of a meta data, now my question is what should be the structure of metadata and all the information it should have?

I am going to use Microsoft SQL Server to develop my data warehouse, but one thing makes me confused. Since Analysis Service can create a Star schema database, do I have to pre-set up a Star schema database for ETLed data? Basically, I am wondering what's the relationship between an ETLed database and the one created through the Analysis Services.
Can any one give me an explanation from the implementation perspective?
Many thanks!

Hi all,
I am trying to restore my data warehouse from a January 2008 backup under a new name to recover a table that I accidentally deleted. It is taking a long time for the restore to get done. Here is the command I am running as sa in QA
---
RESTORE DATABASE Warehouse_new FROM DISK = 'H:MSSQLDataMSSQLBACKUPDBBackupsWarehouseWa rehouse_db_200801050600.BAK'
WITH
MOVE 'Warehouse_Data' TO 'G:MSSQLDataMSSQLDataWarehouse_New_Data.MDF',
MOVE 'Warehouse_Log' TO 'H:MSSQLDataMSSQLLogsWarehouse_New_Log.ldf'
----
There Warehouse_New_Data.MDF is 375 GB and the log is 12 GB.
There is still 169 GB of free space on the drive I am restoring to after the presence of Warehouse_Data.MDF and Warehouse_New_Data.MDF (each 375 GB).
Its been 4.5 hrs and the restore is still running. Backups take about 3.5 hrs to complete. Can I do any checks on the restore to see what point it is at? I stopped the restore using EM earlier after it took 8 hours and still no progress.
Please advise.
Thanks.

Destination: Sql server 2005
ETL tool: SSIS
Problems:
How to refresh or load the current data to data warehouse.(now i'm using truncate sql task for deleting old/entire data for each packages, i really dont want to use in the production) . For example: The patient admissions data is adding everyday so i want to load the current data into my warehouse.
Could you pls suggest me good solution for this?
Refresh Cycle timings: is there any task available in SSIS?
current status:
First Time load completed, i set one Execute Sql statement ctrl flow task for Truncate the existing loaded data in the sql server 2005. and then again i process one data flow task for loading the data from oracle to sql server.

Is SSIS a tool for extracting realtime data from staging to data warehouse? Realtime in my case can be loading every 15 minutes but no more than 30 minutes. I've a data warehouse which data refresh once a day and it worked fine. The data that I extract into the warehouse is from a Staging database which is realtime replication of multiple production databases. Once a day, I've to have replication pauses on staging for a couple hours to refresh the data warehouse. That's the only way so SSIS can pull the data correctly; if I've replication on while SSIS pull data, it will always copy less rows than it supposed to.
I cannot afford to have replication pauses every 15 minutes just so I can refresh data warehouse. Does anyone every have this problem? or any best practice how to do this?
Thanks,
-Ash

At my office, we've been slowly working on putting together a data warehouse.
We're a financial services company and one of the services that we offer is debt collection. As far as reports go, our clients are interested in knowing how much money we collect over time. In particular, they want to know how many payments we've gotten 5, 10, and 15 months (and so on) after we receive a case. (Obviously, the 5-month payments are also included in the 10 and 15-month calculations).
When I wrote this report using our transactional database, I was completely new to SQL and the ever-resourceful Patron Saint took pity on me, so you can see a good description of the details at http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=78510
Now that I'm no longer a total newbie at SQL, and having been through a relatively extensive seminar on data warehousing, I've been entrusted with researching certain aspects of data warehouse development (rest easy, though, folks - the real DWH work is not being done by the very inexperienced me, but by an actual professional :) ).
My question:
how would you model this kind of "relative time" in a data warehouse? How would you display the 5-month, 10-month, and 15-month payments in a DWH? I can't really imagine that the kinds of joins necessary to do this in a transactional database would be desirable in a data warehouse.
We have the following:
1.) FACT_Payment: A fact table showing each each payment to the most detailed granularity. One attribute of this table is the payment date. Another attribute is a foreign key to the case dimension described below.
2.) DIM_Case: A dimension table showing information on each case, including the case start date. DIM_Case
3.) DIM_Date: A date dimension table.
(For added clarification: The FACT_Payment payment date has to be 5, 10, 15 months etc... after the DIM_Case start date.)
Any ideas, comments, experience with something like this?
Thank you.

Hi all,
I'm working on my first data warehouse and I'm not sure how I should name the columns in the database.
The first phase of the data warehouse is to store a bunch of data from one third party source. The source contains over 100 pieces of data and the business user doesn't even know what some of the fields are but he wants to store everything. The third party refers to the each field with a somewhat cryptic short name and a longer description. The short name isn't always cryptic.
My question is am I better off naming my columns the same as the source system's short name so that I can easily debug problems later? Should I instead try to shorten their definition into something meaningful? On a side note, I'm 100% positive that we'll never populate the tables in questions with data from an additional source.
Thanks!

I need someone to give me a small briefieng on how a enterprise data warehouse (EDW)differs from a regular database?
Currently we have an appplication that accesses a database with about 18 tables. We also have a Data Warehouse. For some reason I was thinking that it would be possibly to migrate thedatabase into the data warehouse. The reason is that in looking at the schematic design forthe data warehouse there are some data tables that could also be used by our application that uses the DB.
I guess I am confused because I am not sure if a data warehouse is used in the same wayas a database?

I am very early on in developing a website to track issues with projects which is tied to a SQL database. I have my Projects Table, my Users Table, and am creating a third table to track issues. I'm wondering what is the best way to assign specific users to specific data/projects. The user should only be able to view & update the projects assigned to him. He should not be able to see other projects. What is the best way to assign projects/data to the users to make sure they are only viewing their data?
