Assertion Support for Manipulating Constrained Data-Centric XML

XML is used for different purposes. They are interested in data-centric applications of XML where it is used to handle structured data in loosely coupled, distributed systems. In many such scenarios, it is important that the XML data complies to structural and integrity constraints, in particular to value-based constraints. This...

Addressing Budget Constraints Through Testing

The increasing unrest of the economic climate is influencing business decision makers to take precautionary measures. Controlling the finances of the business has always been important but the shift in confidence means that those in charge now want more for their money. Financial prudence is forcing budgetary review. Departments are...

IDX Variable Constraint System for AutoCAD 2007 1.0 (Windows)

The Variable Constraint System provides variational sketching functionality within AutoCAD. It enables geometric or dimensional constraints to be applied that control relationships between drawn objects. Constraints may be applied to unbound lines, circles, ellipses, arcs, splines, points, and specific geometries in two dimensions, or a two-dimensional subspace of three dimensions....

Semantic Query Optimization for Processing XML Streams With Minimized Memory Footprint

XQuery evaluation over XML streams requires the temporary buffering of XML elements. This paper presents a semantic query optimization solution to minimize memory footprint during XQuery evaluation by exploiting schema knowledge. The focus is on one particular class of constraints, namely, the Pattern Non-Occurrence PNO constraints for XML streams conforming...

Resource Allocation in CDMA Packet Systems With Maximum Rate Constraint

Scheduling algorithms in CDMA packet systems need to allocate codes and power based on channel state information and queue information. For finite queue sizes, the allocated rate should be less than or equal to the maximum rate required to clear the whole queue. This ensures that resources are not under-utilized....

Revisiting Probabilistic Models for Clustering With Pair-Wise Constraints

This paper revisits recently proposed algorithms for probabilistic clustering with pair-wise constraints between data points. Existing techniques are evaluated and compared in terms of robustness to misspecified constraints. It is shown that the technique that strictly enforces the given constraints, namely the chunklet model, produces poor results even under a...

Refactoring Using Type Constraints

Type constraints express subtype-relationships between the types of program expressions that are required for type-correctness, and were originally proposed as a convenient framework for solving type checking and type inference problems. This paper shows how type constraints can be used as the basis for practical refactoring tools. In one's approach,...

Enforce Business Rules for All Your Data With Constraints

Of the several ways to enforce business rules in the database, only constraints can guarantee that the business rules are always enforced for all the data. This paper teaches how to apply foreign key constraints with the ON UPDATE CASCADE clause to implement waterproof solutions for several common real world...

How do I... Enforce domain integrity for SQL Server data using CHECK constraints?

Even simple errors in data can result in huge problems. Luckily, you can eliminate at least some of those errors by using CHECK constraints to force users to enter data that meets specific conditions. Database expert Susan Harkins explains this approach and then walks through an example demonstrating how...

Cross-Layer Congestion Control, Routing and Scheduling Design in Ad Hoc Wireless Networks

This paper considers jointly optimal design of cross-layer congestion control, routing and scheduling for ad hoc wireless networks. The paper first formulates the rate constraint and scheduling constraint using multicommodity flow variables, and formulates resource allocation in networks with fixed wireless channels (or single-rate wireless devices that can mask channel...

TranslateSQL 1.0 (Windows)

TranslateSQL is a utility for converting an Oracle schema into an SQL build script for SQL-Server. Unlike the import wizard that comes with SQL-Server, it actually converts all the indexes, primary keys, foreign constraints, and check constraints. However, it does not copy the data in each of the tables, nor...

XML Constraints: Specification, Analysis, and Applications

To make effective use of XML constraints it is often necessary to reason about them, both at compile-time for consistency and implication analyses and at run-time for incremental constraint checking. Since XML constraints are more complicated than relational dependencies, the static analyses of XML constraints are more intriguing than their...

Constraint-Based Routing in the Internet: Basic Principles and Recent Research

Novel routing paradigms based on policies, Quality of Service QoS requirements, and packet content has been proposed for the Internet over the last decade. Constraint-based routing algorithms select a routing path satisfying constraints which are either administrative-oriented policy routing, or service-oriented QoS routing. The routes, in addition to satisfying constraints,...
