Big Data Still Requires Humans To Make Meaningful Connections

This is great article as many of us think that technology is everything. No matter the rich technology we have, still human interventaion is needed for meaningfull connections.

“Perhaps it’s because we put so much faith into technology to solve our problems. We have been led to believe big data is going to help businesses make smarter and more informed decisions.”

“We tend to believe that technology is the answer when it’s just a tool in the hands of humans. As anyone who has watched an episode of Law and Order can attest, you can have the DNA evidence at the scene of the crime, but the detectives still have to do the hard work of finding the person connected to that bit of data. The data is useless without the human element to connect the dots.”

Tutorial: Data Science with SQL Server R Services

You may have heard that R and the big-data RevoScaleR package have been integrated with with SQL Server 2016 as SQL Server R Services. If you've been wanting to try out R with SQL Server but haven't been sure where to start, a new MSDN tutorial will take you through all the steps of creating a predictive model: from obtaining data for analysis, to building a statistical model, to creating a stored prodedure to make predictions from the model. To work through the tutorial, you'll need a suitable Windows server on which to install the SQL Server 2016 Community Technology Preview, and make sure you have SQL Server R Services installed. You'll also need a separate Windows machine (say a desktop or laptop) where you'll install Revolution R Open and Revolution R Enterprise. Most of the computations will be happening in SQL Server, though, so this "data science client machine" doesn't need to be as powerful.

ETL FRAMEWORK DESIGN FOR NOSQL DATABASES IN DATAWARE HOUSING

With the development of Web 2.0 significantly semi-structured, unstructured data has been generated. Typical RDBMS are lack of scaling and inefficient of handling Big data So the NoSQL Databases have the capabilities of handling those kind of data. Even though NoSQL databases are there, RDBMS are still remaining in the industry since some of features are not yet supported by the NoSQL databases, such as ACID properties. The typical Data warehouse consists of repository of data and those are non-volatile and extracting from different heterogeneous data sources. Since the central repository of data allows make strategic decisions of an organization. ETL is the process which used in extracting data, transform data to suit to data warehouse environment and load the data to the targeted data warehouse database. There were similar researches on for extracting data from NoSQL databases. However, those have limitations such as specific only for one vendor and only extraction is considered and transformation and loading to data warehouses with ETL characteristics are not addressed. Aim of this research on NoSQL ETL will be vital since currently data warehouses are consists of structured data and this will leads to store unstructured data in data warehouse and allows making strategic decisions, data analysis on top of it.

This article focuses Time Series Algorithms which are a forecasting technique. One of the most common algorithms used in industry are time series algorithms which can be used to answer questions on the future values such sales volume for the next season, or petrol prices in winter. Most of the cases, time series algorithms are limited to prices and quantities. However, using the same theories and techniques, they have the capabilities of predicting trajectory or a moving object and next video frame.

Microsoft Readies Big Data Service That Includes New U-SQL Language

Earlier this year, Microsoft revealed plans to offer a new HDFS-compatible Hadoop File System data store that could run large analytics workloads called Azure Data Lake. So far, the technical preview hasn't appeared but the company today reiterated that the service, which it will actually call Azure Data Lake Store, will be available later this year and also announced some new services planned for its Azure-based Big Data portfolio.

Dealing with an Inherited SQL Server

If you work with SQL Server you’ve most likely been there at one time or another. Maybe you’ve just started a new job, or you might be a Windows administrator who has been tasked to manage SQL Server, or you might be a consultant who has been brought in to deal with a specific problem.  The end result is that you wind up working with a SQL Server instance and one or more databases that you know nothing about.

SQL Server 2016: Live Query Statistics

A database query times out and you don’t know why. The estimated query plan is revealing the problem, so you remove the timeout entirely. An hour later it is still running and you are no closer to getting the actual execution plan. If only there was a way to find out what is actually happening inside the server.

With Live Query Statistics in SQL Server 2016 you can now answer that question. This new feature offers the DBA a live version of the execution plan with annotations detailing which steps are currently being performed.

Ex-Microsoft chief rolls elastic-SQL challenge to Amazon Redshift

SQL Server, with Windows and Office, helped make Microsoft. The database sits in a $13bn business unit and while Microsoft’s server products grew 11 per cent – $1.7bn last year – that was driven primarily by sales of SQL Server.

The man who paved the path was Bob Muglia. A 24-year Redmond veteran, he was SQL Server’s first product manager and led the server and tools business.

That was until 2011, when he was elbowed out by ex-CEO Steve Ballmer in a disagreement over strategy for the server and tools business.

Also, the 2008 DATAllegro acquisition, to build a Netezza-like appliance, had proved to little and too late for Microsoft as the market had moved.

SQL Server 2016: Dynamic Data Masking

Row-level security is great for all or nothing decisions, but there are times when users need access to a subset of the data. For example, the last four digits of a credit card or social security number. This can be done at the application level, but that leaves room for error. You only need to forget the mask one time to leak sensitive data.

SQL Server 2016 attempts to address this with a feature called Dynamic Data Masking. When a column is created with a mask, it defaults to returning only the data exposed through the mask. There are three types of masks currently available:

Who is a DBA

WHO IS A DBA? A database administrator (DBA) directs or performs all activities related to maintaining a successful database environment. Responsibilities include designing, implementing, and maintaining the database system; establishing policies and procedures pertaining to the management, security, maintenance, and use of the database management system. To make long story short A DBA is the backbone of  any mission critical system.

check whether the list is correct.

http://sqlindia.com/who-is-a-dba/

SQL Server 2016: Row-Level Security

A common criticism for SQL Server’s security model is that it only understands tables and columns. If you want to apply security rules on a row-by-row basis, you have to simulate it using stored procedures or table value functions, and then find a way to make sure there is no way to bypass them. With SQL Server 2016, that is no longer a problem.

We Need Only Three Hadoops, And Maybe Three Systems

Enterprises like choices, they abhor vendor lock in, and they like the options that open source gives. But at the same time, too many choices fragments markets and doesn’t allow for the cultivation of larger vendors that can afford to take on the big problems. You need a balance between large enough to scale and so large as to be too overbearing, or sometimes, in the antitrust sense, to be abusive.

With the Hadoop Summit sponsored by Hortonworks going on this week and some tectonic changes in the systems market that have been going on for some months now, we are pondering how this all fits together given the current state of both Hadoop and the systems markets.

SQL Server 2016 : Getting tempdb a Little More Right

 has written a nice blog post about tempdb improvements in SQL Server 2016. You can read more from http://blogs.sqlsentry.com/aaronbertrand/sql-server-2016-tempdb-fixes/.

The most important feature for me is ability to configure multiple files to tempdb during the installation. Currently, you need to do this manually and restart the server which will not be required with SQL Server 2016. In the configuration it also check the number of cores and provide the guide line as well.


What is the SQL Server 2016 Query Data Store?

Query Data Store in SQL Server 2016 is intended as a service that monitors and optimizes query plans with full history of query execution. Query Data Store can help diagnose performance problems that are related to plan changes.
What it does:
  1. Stores the history of query plans
  2. Captures performance data for each query plan
  3. Identifies the most expensive queries and earmarks those queries that have degraded or gotten slower over time
  4. Gives you the ability to force old plans, should a new plan cause performance issues (almost like a system restore for Windows computers)
  5. Easily fixes plan regressions
  6. Analyzes workload patterns
  7. De-risks SQL Server upgrades with restart and failover

Support for SQL Server 2005 Ends April 12, 2016

oduct expiration is a fact of life. And, no matter how much we love a product or no matter how long we cling to its familiar interface, we eventually have to give up on it.

Such is the case with SQL Server 2005. SQL Server 2005 is the next in a running lot of product expirations, with the end of support date being April 12, 2016.  Released 10 years ago, this version of Microsoft's database product is still in use in a huge number of implementations. So, it goes without saying that, just like we've seen with Windows XP and Windows Server 2003, some organizations will have a tough time letting go.

MSSQL Server 2016 coming with JSON Support

With over a thousand votes on the Microsoft Connect site, JSON support is the most requested feature for SQL Server 2016. This month, Microsoft announced that the upcoming release of SQL Server 2016 will fulfill that request. Sort of.

Microsoft will certainly be touting this feature as an additional reason to upgrade when the time comes. Natively supporting JSON helps bridge the gap between the desirable aspects of a NoSQL database and a relational database like SQL Server. The trouble is that with this current implementation, you're not really gaining anything over what's currently available. It's nothing like the native XML data type that became available starting with SQL Server 2005.

Changing the SSRS Subscription Owner

When subscriptions are created, owner of that subscription will be the user who creates it. However, when that user account is disabled, subscriptions will be failed and there is no way from the user interface to change it. However these subscriptions are stored in subscriptions table of ReportServer database (default database of the SSRS. This may be different if you have changed it from the SSRS configuration manager). In the subscription table, user id is stored as a unique identifier which you should get from the users table. Update query is shown below.

USE ReportServer

GO

DECLARE @OldUserID uniqueidentifier

DECLARE @NewUserID uniqueidentifier

SELECT @OldUserID = UserID FROM dbo.Users WHERE UserName = 'DOMAIN\previous_user'

SELECT @NewUserID = UserID FROM dbo.Users WHERE UserName = 'DOMAIN \ new_user’

UPDATE dbo.Subscriptions SET OwnerID = @NewUserID WHERE OwnerID = @OldUserID

No restart is of SSRS or SQL Server services are required. Soon after you update the userids subscriptions will start to work.

The World According to DBAs

Database administrators (DBAs) are at the frontline of data management in most enterprises, identifying and often choosing to adopt new technologies. According to a new survey of DBAs, "While Hadoop and NoSQL are exciting new technologies," primarily large companies use them now and they "do not factor into many companies' plans over the next few years." Furthermore, traditional database management systems remain the foundation for information management infrastructure in most organizations, with Oracle and Microsoft SQL Server the dominant platforms for supporting mission-critical data. To examine the database infrastructure, understand the roles of DBAs today and how their roles are changing, Dell commissioned Unisphere Research, a division of Information Today, to survey database administrators and others charged with managing corporate data. There were 300 respondents from a wide range of companies representing a dozen industries. Two-thirds came from organizations with more than 1,000 employees. One-quarter of respondents' organizations run more than 500 databases. - See more at: http://www.cioinsight.com/it-strategy/big-data/slideshows/the-world-according-to-dbas.html#sthash.9u6JjSqn.dpuf
