microsoft sql server PowerPivot for Excel, or PowerPivot for short, is an in-memory business intelligence (BI) engine that enables Excel users to interactively create pivot tables over large data sets imported from sources such as relational databases, text files and web data feeds. Unlike traditional pivot tables in Excel that are defined on a single table, PowerPivot allows analysis over multiple tables connected via foreign-key joins. In many cases however, these foreign-key relationships are not known a priori, and information workers are often not be sophisticated enough to define these relationships. Therefore, the ability to automatically discover foreign-key relationships in PowerPivot is valuable, if not essential. The key challenge is to perform this detection interactively and with high precision even when data sets scale to hundreds of millions of rows and the schema contains tens of tables and hundreds of columns. In this paper, we describe techniques for fast foreign-key detection in PowerPivot and experimentally evaluate its accuracy, performance and scale on both synthetic benchmarks and real-world data sets. These techniques have been incorporated into PowerPivot for Excel.

Cloud sqlserver is a relational database system designed to scale-out to cloud computing workloads. It uses microsoft sql server as its core. To scale out, it uses a partitioned database on a shared-nothing system architecture. Transactions are constrained to execute on one partition, to avoid the need for two-phase commit. The database is replicated for high availability using a custom primary-copy replication scheme. It currently serves as the storage engine for microsoft's Exchange Hosted Archive and sql Azure.

In this paper we present a system intended for content-based image retrieval tightly integrated with a relational database management system. Users can send query images over the appropriate web service channel or construct database queries locally. The presented framework analyses the query image based on descriptors which are generated by the bag-of-features algorithm and local interest points. The system returns the sequence of similar images with a similarity level to the query image. The software was implemented in. NET technology and microsoft sql server 2012. The modular construction allows to customize the system functionality to client needs but it is especially dedicated to business applications. Important advantage of the presented approach is the support by SOA (Service-Oriented Architecture), which allows to use the system in a remote way. It is possible to build software which uses functions of the presented system by communicating over the web service API with the WCF technology.

This study evaluates mechanisms to secure relational databases against security vulnerabilities and utilized Postgresql and microsoft sql server due to data breach incidences reported across the world. Emulation experiments with documentary review were employed to collect necessary study data. Identification of security features and vulnerabilities that are found to affect the data tier of the web applications were examined. The findings from the study have shown that microsoft sql server is more security feature-rich in terms of Confidentiality, Integrity, and Availability compared to Postgresql and microsoft sql server is more resilient to security attacks in its default behavior compared to Postgresql.

Testing of newly programmed components is an integral part of software development. Data Generator for microsoft sql server is a tool for simple populating database tables with testing data which allows efficient database component testing for programmers, administrators and other database developers. Generated data can be structured using the parameters which are set in a simple user interface. Generated data correspond with database schema and constraints defined on columns. In following text we are going to describe the architecture and implementation details together with the necessary theoretical knowledge.
