Data engineering is the modeling and structuring of data in its design, development and use. An ultimate goal of data engineering is to put quality data in the hands of users. Specifying and ensuring the quality of data, however, is an area in data engineering that has received little attention. In this paper we: (1) establish a set of premises, terms, and definitions for data quality managemen...

This paper presents common weaknesses of requirements documents from commercial software projects that frequently cause problems in practice. Many documents contain extensive, unstructured or even superfluous descriptions of details. At the same time, they lack a thorough description of the aim of the software system or one of its features. Such documents are difficult to read and to work with ...

Quality of service (QoS) has been a feature of voice communication networks almost since their inception. The extension of traditional voice QoS methods to data communication networks and the Internet has been a longstanding research topic, although for many years it was not considered a critical issue due to the inherent differences between data and voice traffic and the relatively low cost of...

INVITED GUEST Time and Place TOPIC Prof. Dr. Maritta Heisel University of Duisburg – Essen (Germany) Monday, 30th June 2014, 09:15 Room 001 Albert-Einstein-Straße 22, 18059 Rostock I will give an introduction to problem frames as proposed by Michael Jackson. Problem Frames are patterns for simple software development problems. Then, I will show how the problem frames notation can be carried ove...

Several surveys have shown that about 80% of data in local governments and utility companies are geographical and 1.5% to 2% of the annual budget of such sectors is spent on collecting geographic information. Therefore, such reliance on geographic information has necessitated the development of high quality Geographic Information Systems (GIS) with system qualities such as performance, availabi...

A process is a set of activities which produces an output -product or servicevaluable for the customer. Ensuring quality of products and services requires high amounts of cooperation between the different actors in an organization. This suggests the use of workflow techniques in order to implement quality. Workflow management systems allow the control of flow of work and guarantee that a job sh...

The clinical significance of estrogen receptor (ER) levels determined in breast cancer tissue depends on the quality of the ER assay procedure itself as well as on several critical factors beyond the direct responsibility of the receptor laboratory. A novel immunobiochemical assay (ER-EIA) has been made available by Abbott Laboratories. In comparison to the classical radioligand binding assay, ...

We recognize the need for deening a quality model of linguistic properties of natural language requirements. We are convinced that the deenition of a thorough linguistic quality model can be obtained as a meeting point between the specialization of high level quality frameworks for requirements engineering on one hand, and a systematic collection and classiication of the diierent Natural Langua...

In order to develop a software product for a critical system, specifying quality requirements is vitally important. Quality requirements should be defined based on various stakeholders’ needs. Software quality impacts the information system’s behavior, and the behavior impacts the behavior of the External-System that contains the information system. Safety is an issue of the External-System. A ...
