One of the critical deficiencies of SQL is the lack of support for array and spreadsheet like calculations which are frequent in OLAP and Business Modeling applications. Applications relying on SQL have to emulate these calculations using joins, UNION operations, Window Functions and complex CASE expressions. The designated place in SQL for algebraic calculations is the SELECT clause, which is ...

Monitoring a large number of SQL Servers in an enterprise is a difficult task. The SQL Server administrators have to deal with a large amount of very dynamic and diverse information, and many other complicating factors. We found that the age-old principle of management by exception provides an effective framework in organizing our monitoring efforts. This paper describes our experience in using...

Completely handling SQL injection consists of two activities: properly protecting the system from malicious input, and preventing any resultant error messages caused by SQL injection from revealing sensitive information. The goal of this research is to assess the relative effectiveness of unit and system level testing of web applications to reveal both error message information leak and SQL inj...

In this review, the authors study how a hybrid optomechanical system (OMS), in which quantum micro- or nano-mechanical oscillator is coupled to electromagnetic radiation pressure, consisting of an ensemble ultracold atoms atomic Bose–Einstein condensate, can be used as ultraprecision sensor for measuring very weak signals. As well-known any precise measurement, competition between shot noise an...

Comparing two databases that were upgraded from Sql Server 2008 R2 to Sql Schema & Data Comparison work well when Sql Client is 2012 SP1, but not. Diffing Your Microsoft SQL Server Database Structures It was lightning-fast, taking less than 8 seconds to compare two databases on different servers. SQL server database project creation using Visual Studio 2013, Author: The work is tougher when we ...

We demonstrate a full-fledged implementation of first-class functions for the widely used PL/SQL database programming language. Functions are treated as regular data items that may be (1) constructed at query runtime, (2) stored in and retrieved from tables, (3) assigned to variables, and (4) passed to and from other (higher-order) functions. The resulting PL/SQL dialect concisely and elegantly...

We describe FACTORBASE , a new framework that leverages a relational database management system (RDBMS) to support multi-relational graphical model learning. The basic insight behind our approach is that an RDBMS can be leveraged to manage not only big data, but also to manage big models [1, 2]: First, model structure and model parameters can be managed efficiently without having to be stored i...

Future users of large, interconnected databases and data warehouses will increasingly require schematic transparency of data manipulation systems, in that (i) data from heterogeneous sources must be compared and interrelated and (ii) data must be queried and extracted by distant users having minimal knowledge of its logical structure. A query language that abstracts over meta-data as well as or...

SQL injection attacks are one of the highest dangers for applications composed for the Web. These attacks are dispatched through uncommonly made client information on web applications that utilization low level string operations to build SQL queries.SQL injection weakness permits an assailant to stream summons straightforwardly to a web application's hidden database and annihilate usefulness or...
