Team Foundation Server (commonly abbreviated to TFS) is a Microsoft product that provides source code management (either with Team Foundation Version Control or Git), reporting, requirements management, project management (for both agile software development and waterfall teams), automated builds, lab management, testing and release management capabilities. It covers the entire application lifecycle, and enables DevOps capabilities. TFS can be used as a back-end to numerous integrated development environments (IDEs) but is tailored for Microsoft Visual Studio and Eclipse on all platforms.

Business intelligence and business analytics… aren’t they the same thing?

Or are they describing opposite processes?

There are a lot of big words that get thrown around in the world of BI, and it’s easy to get lost in a whirlwind of interpretation

In this article we will explore more about the difference

There is a lot of buzz around SQL Server 2016.  Microsoft announced the release of SQL Server 2016 at the Microsoft Ignite Conference during the first week of May 2015. Since that time a number of Community Technical Previews (CTPs) have come out. We can review some of the new features. In this article we are exploring, at a very high level, 10 of those new features.

The promise of data-­-driven decision-­-making is now being recognized broadly, and there is growing enthusiasm for the notion of ``Big Data.’’
We are awash in a flood of data today. In a broad range of  application areas, data is being collected
at unprecedented scale. Decisions that previously were based on guesswork, or on painstakingly constructed models of reality, can now be made based on the data itself. Such Big Data analysis now drives nearly every  aspect of our modern society, including mobile services, retail, manufacturing, financial services, life sciences, and physical sciences.

The term "Cloud Computing" has been mentioned for just under two years in relation to services or infrastructural resources, which can be contracted over a network. Thus, the idea of renting instead of buying IT is nothing new. And so, Cloud Computing has many antecedents and equally as many attempts to define it. The players in the large world of clouds are Software as a Service providers, outsourcing and hosting providers, network and IT infrastructure providers and, above all, the companies whose names are closely linked with the Internet's commercial boom. But, all these services in combination outline the complete package known as Cloud Computing – depending on the source with the appropriate focus.

The application flow in ODBC is similar to the application flow in OLE DB. In both cases, the application:

• Initializes the environment.

• Connects to a data source.

• Creates and executes a command.

• Processes results, if any.

• Cleans up.

There are 4 High Availability options in SQL Server 2008 that we will cover; Failover Clustering, Database Mirroring, Log Shipping and Replication. Each one has its own features and benefits.  As you may know, the Recovery Time Objective (RTO) which is the tolerable maximum length of time that a system can be unavailable and Recovery Point Objective (RPO) which is how much data can be lost, need to be considered to meet the organizational objectives for each application that is critical to the business. Any desired High Availability option should satisfy

these objectives.

Data is growing everywhere, and the amplification of data affects every imaginable device, application, and process as our world rapidly evolves into digital and virtual transactions and experiences. It is no longer the case that organizations serve customers during standard business hours in single time zone or geography. Today, services are continually available to customers through a range of operational measures, from Internet presence at the very minimum to tracking complex operations globally for the highest efficiencies and customer satisfaction.

There are several high availability solutions that can be used with SQL Server, like AlwaysOn, Fail-over clustering, or Database mirroring. While these high availability solutions ensure maximum uptime for your databases, you need to setup backup and restore strategies to recover the data or minimize the risk of data loss in case a failure happens.

It is quite common to have an OLTP database that must store large amounts of data which pile up into hundreds of millions, even billions, of rows. What do we do in such cases? In this article I will describe a way to deal with constant flows of OLTP data into production systems, and how to offload this data, describing the process from beginning to end.

This guide to building the infrastructure for hosting Microsoft® SQL Server® Database as a Service (DBaaS) is not limited to a particular type of hardware. By using the features of SQL Server 2014 and Hyper-V® virtual machines with Microsoft System Center 2012, a hosting service provider can start with very small tenant databases and scale out or scale up to meet the needs of the largest and busiest SQL Server applications. This reference architecture includes hardware, software, system design, and component configuration.

Below are my observations on some of the differences between CR/CE and SSRS. These

observations are based on the use of these software packages for ad hoc report design and web delivery of the reports. I don’t do any standalone application development and can’t speak to their capabilities in these areas. This list is by no means complete and some things are completely a matter of opinion. I hope this can help you in your decision.

In this section, we discuss the primary changes made to the CE component for SQL Server 2014. The legacy CE’s default behavior has remained relatively static since SQL Server 7.0. The SQL Server 2014 changes address performance issues for key scenarios based on benchmark and customer workload testing. The new CE design also lays the groundwork for future improvements.

This migration guide provides guidance for customers who have deployed database mirroring for local high availability and log shipping for disaster recovery based on SQL Server 2008 R2 or earlier and now want to upgrade to use SQL Server 2012 AlwaysOn Availability Groups. The migration sequence presented here is a best-practice approach that preserves the high availability and disaster recovery capabilities of your databases during most of the migration process.

Single Version of the Truth: MicroStrategy’s single metadata ensures consistent KPI definitions across the entire enterprise.

Multiple Versions of the Truth: Tableau deployments typically have a number of small metadata models (a.k.a. Tableau Data Source). The lack of a centralized metadata model results in creation of multiple disconnected analytical silos and promotes multiple versions of the truth. There is limited/no reusability of analytical definitions across the multiple Tableau metadata models.

SQL Server was originally designed at a time when it could be assumed that main memory was very expensive, so data needed to reside on disk except when it was actually needed for processing. This assumption is no longer valid as memory prices have dropped enormously over the last 30 years
