Tableau Self-Service Tool for Visualization, new features

[Data in Tableau ]
[Data in Tableau ]
Tableau is moving into the data-wrangling business, announcing plans for visual data-preparation software code-named Project Maestro.
The idea is to bring the same sort of "self-service" visualization to the prepping and cleaning of data as they've built for data analysis.
Visual ways of inspecting, joining and editing data. Results could then be piped into Tableau for analysis.
The other features
  • Speedier data import and analysis. Tableau's new data engine in the works, based on Hyper technology it acquired earlier this year, should make it significantly faster to import and analyze large data sets with Tableau. A conference demo showed hundreds of thousands of records being imported per second, as well as being visualized in real time as the import process continued. The engine is in part a response to customer feedback that building large data extracts took too long.

  • Natural-language queries. Tableau is aiming for true natural speech, not merely being able to type in questions that require using exact field names and functions. The demo included queries such as "show houses near Ballard," which brought up a map of such homes and their selling prices as well as a slider to alter the radius definition of "near." The system would be able to understand a query such as "Show me the most expensive houses near Ballard last summer" without having to explicitly define "most expensive" as the maximim of price field or "last summer" as a particular date range. Next, a user would be able to simply type "show me the cheapest houses" and the system would understand this was similar to the prior query, without needing to repeat "near Ballard last summer."
  • Data governance that allows organizations to certify trusted content and calculations and share useful calculations created in one workbook with all users on the company's Tableau Server.
  • Recommended analyses so Tableau would suggest visualizations and other analysis based on your data set.
  • Pre-built recommended dashboards from cloud services, including combining data from multiple services. This will start next year with four services: Salesforce, Marketo, Eloqua and Quickbooks

Four Tableau products a quick review and explanation

I want to share you what are the Products most popular.

Total four products. Read the details below.

Tableau desktop-(Business analytics anyone can use) - Tableau  Desktop  is  based  on  breakthrough technology  from  Stanford  University  that  lets  you drag & drop to analyze data. You can connect to  data in a few clicks, then visualize and create interactive dashboards with a few more.

We’ve done years of research to build a system that supports people’s natural  ability  to  think visually. Shift fluidly between views, following your natural train of thought. You’re not stuck in wizards or bogged down writing scripts. You just create beautiful, rich data visualizations.  It's so easy to use that any Excel user can learn it. Get more results for less effort. And it’s 10 –100x faster than existing solutions.

The Sqoop in Hadoop story to process structural data

Why Sqoop you need while working on Hadoop-The Sqoop and its primary reason is to import data from structural data sources such as Oracle/DB2 into HDFS(also called Hadoop file system).
To our readers, I have collected a good video from Edureka which helps you to understand the functionality of Sqoop.

The comparison between Sqoop and Flume

The Sqoop the word came from SQL+Hadoop Sqoop word came from SQL+HADOOP=SQOOP. And Sqoop is a data transfer tool. The main use of Sqoop is to import and export the large amount of data from RDBMS to HDFS and vice versa.

The best 5 differences of AWS EMR and Hadoop

With Amazon Elastic MapReduce (Amazon EMR) you can analyze and process vast amounts of data. It does this by distributing the computational work across a cluster of virtual servers running in the Amazon cloud. The cluster is managed using an open-source framework called Hadoop.

Amazon EMR has made enhancements to Hadoop and other open-source applications to work seamlessly with AWS. For example, Hadoop clusters running on Amazon EMR use EC2 instances as virtual Linux servers for the master and slave nodes, Amazon S3 for bulk storage of input and output data, and CloudWatch to monitor cluster performance and raise alarms.

You can also move data into and out of DynamoDB using Amazon EMR and Hive. All of this is orchestrated by Amazon EMR control software that launches and manages the Hadoop cluster. This process is called an Amazon EMR cluster.
