Whether the Data output from Alteryx can be mapped to Tableau Reports directly or do we need to store the Data output in an intermediate Database (like SQL Server).
Altyryx can generate a Tableau data extract or write to a relational database. Tableau can read from either format. Your choice.
Yes you can publish from Alteryx to Tableau go to Connector and then select "Publish to Tableau Server Tool" if you don't to have the tool. download it from here:

We have developed a model in Tabular Object Model(TOM), <= 3.5 GB in size., and built few Tableau Dashboard(s) on top of this model.
Each dashboard is built by dragging multiple sheets into one dashboard. All the sheets (dragged in one dashboard) fetch data from one fact table (of course it has relationships with Date and other related dimensions) in TOM.
Now, when we interact with Tableau dashboard, we see a performance degradation. When we checked the SQL profiler, Tableau is generating a huge query for almost every interaction that we have with the dashboard.
We checked the huge query and observed that it includes the DAX/query for almost all the measures in fact tables, irrespective of whether the fact table is used in the said dashboard or not.
We have verified the filter settings in the dashboard, the settings are applicable only for the sheets dragged in our dashboard, so there is no question of visualizations getting changed in other dashboards.
Ironically, we still see that Tableau is creating a huge query and incorporating all the DAX/queries and this results into performance impact.
Is there any way we can restrict this behavior?
In case anyone else is having this issue, this is tied into Tableau not actually supporting SSAS Tabular, the connector you using is for SSAS Multidimensional so Tableau generates MDX queries against the DAX-based Tabular model.
This is also evident from Tableau's own techspecs site:
https://www.tableau.com/products/techspecs
"Microsoft SQL Server Analysis Services 2008 SP4 or later, multi-dimensional mode only*
"
Tableau's website at https://www.tableau.com/products/techspecs clearly states support for
"Microsoft SQL Server Analysis Services 2005 or later, non-tabular mode only*(incl. support for Kerberos)"
I want to connect two database and establish a relationship between them in tableau. One from sql sever and another from Microsoft excel sheet. How to do that?
I have goggled a lot for that but could not get a suitable answer.
You are speaking about Data Blending -
And for connecting cross database data
Cross Database Querying is a Flagship Upgrade to Tableau 10.0
However, you cannot use cross-database joins with these below connection types:
Tableau Server
Firebird
Google Analytics
Microsoft Analysis Services
Microsoft PowerPivot
Odata
Oracle Essbase
Salesforce
SAP BW
Splunk
Teradata OLAP Connector
You just need to connect to each database separately and make sure they have the same column names. When creating a sheet when you switch between datasources you will see a chain on the linked fields.
Do note that this is not properly joined but is just blended data, it would be best to create another table in your sql database for the excel sheet.
Currently we have a workbook developed in Tableau using Oracle server as the data store where we have all our tables and views. Now we are migrating to Redshift fora better performance. We have the same table structure as in the Oracle with the same table names and the field names in the Redshift. We already have the Tableau workbook developed and we need to point to Redshift tables and views now. How do we point the developed workbook to Redshift now, kindly help.
Also let me know any other inputs in this regard.
Thanks,

Use the Replace Data Source functionality of Tableau Desktop
You can bypass Replace Data Source and move data directly from Oracle to Redshift using bulk loaders.
Simple combo of SQL*Plus + Python + boto + psycopg2 will do the job.
It should:
Open read pipe from Oracle SQL*Plus
Compress data stream
Upload compressed stream to S3
Bulk append data from S3 to Redshift table.
You can check example of how to extract table or query data from Oracle and then load it to Redshift using COPY command from S3.
I am very new to using Talend, could some body tell me how to load a excel sheet to SQL-Server 2012?
I tried searching in Google but no help..
I can easily do it using ssis tasks, but much needed using Talend, I took an input as excel and tried making a DB connection but i dont know the connection string or I dont understand what to put as port, Database, schema, Additional parameters.
I tried following these links:
see here
to solve your problem you need 3 components :
-Your Excel input
-A tmap
-A toutput
Join the excel input to the tmap and then the tmap to the dboutput.
Port, Database, Schema, Additional params refers to your database informations
What Talend Open Studio is ?
Talend Open Studio for Data Integration is an open source graphical development
environment for creating and deploying custom integrations between systems. It
comes with over 600 pre-built connectors that make it quick and easy to connect
databases, transform files, load data, move, copy and rename files, and connect
individual components in order to define complex integration processes.
and to answer to the question.
a raw file(excel,csv,xml,etc) put in a tfileInputdelimited then connected to tMSSQLoutput
the connection looks as shown in figure.
then to confiqure the sql server, goto to metadata,db connections-->right click -->create connection-->DB type-->sql server--> it works on sql server authentication so you need to create a user say user1 with some password-->then login-->password-->server_name-->port(1433 default in sql server)-->others left null(is ok)
file is successfully executed
This is something to be understood when trying Talend for the first time :D
I want to transfer some tables of DB2 to oracle daily for accessing them from web page,
But I don't know commands of DB2. How to do this?
I want this action should perform on database daily on particular time, so is there any tool is available to do this operation. And for writing the program for operating above query which programming language should I use? I am using windows XP.
I think Change Data Capture is used to replicate DML from one database to other databases continuously.
However, what you need is to transfer some data at a particular time each day, thus CDC could be too heavy for that.
You could do a simply "db2 export", and then you could import the generated file from Oracle.
There should be an option to create an adapter in Oracle that permits to query DB2 tables. The opposite is called federation in DB2 (InfoSphere Information Server) that permits to query Oracle tables.

In 11.2 releases, Change Data Capture (CDC) can be done by code template mapping. This allows users to capture the data changes from heterogeneous data source, and load into the target across different platforms.
