PAPER ONE

Semi-Automatic Composition of Situational Methods

Anat Aharoni, Kinneret College, Israel
Iris Reinhartz-Berger, University of Haifa, Israel

Situational methods are approaches to the development of software systems 
that are designed and constructed to fit particular circumstances that 
often refer to project characteristics. One common way to create 
situational methods is to reuse method components, which are the building 
blocks of development methods. For this purpose, method components must be 
stored in a method base, and then retrieved and composed specifically for 
the situation in hand. Most approaches in the field of situational method 
engineering require the expertise of method engineers to support the 
retrieval and composition of method components. Furthermore, this is 
usually done in an ad-hoc manner and for pre-defined situations. In this 
paper, the authors propose an approach, supported by a tool that creates 
situational methods semi-automatically. This approach refers to structural 
and behavioral considerations and a wide variety of characteristics when 
comparing method components and composing them into situational methods. 
The resultant situational methods are stored in the method base for future 
usage and composition. Based on an experimental study of the approach, the 
authors show that it provides correct and suitable draft situational 
methods, which human evaluators have assessed as relevant for the given 
situations.

PAPER TWO

DocBase: Design, Implementation and Evaluation of a Document Database for 
XML

Arijit Sengupta, Wright State University, USA
Ramesh Venkataraman, Indiana University, USA

This article introduces a complete storage and retrieval architecture for 
a database environment for XML documents. DocBase, a prototype system 
based on this architecture, uses a flexible storage and indexing technique 
to allow highly expressive queries without the necessity of mapping 
documents to other database formats. DocBase is an integration of several 
techniques that include (i) a formal model called Heterogeneous Nested 
Relations (HNR), (ii) a conceptual model XER (Extensible Entity 
Relationship), (ii) formal query languages (Document Algebra and 
Calculus), (iii) a practical query language (Document SQL or DSQL), (iv) a 
visual query formulation method with QBT (Query By Templates), and (v) the 
DocBase query processing architecture. This paper focuses on the overall 
architecture of DocBase including implementation details, describes the 
details of the query-processing framework, and presents results from 
various performance tests. The paper summarizes experimental and usability 
analyses to demonstrate its feasibility as a general architecture for 
native as well as embedded document manipulation methods.

PAPER THREE

A Meta-Analysis Comparing Relational and Semantic Models

Keng Siau, University of Nebraska – Lincoln, USA

Qing Cao, Texas Tech University, USA

Data modeling is the sine quo non of systems development and one of the 
most widely researched topics in the database literature. In the past 
three decades, semantic data modeling has emerged as an alternative to 
traditional relational modeling. The majority of the research in data 
modeling suggests that the use of semantic data models leads to better 
performance; however, the findings are not conclusive and are sometimes 
inconsistent. The discrepancies that exist in the data modeling literature 
and the relatively low statistical power in the studies make meta-analysis 
a viable choice in analyzing and integrating the findings of these 
studies.

RESEARCH NOTE

Extending Agile Principles to Larger, Dynamic Software Projects: A 
Theoretical Assessment

Dinesh Batra, Florida International University, USA
Debra VanderMeer, Florida International University, USA
Kaushik Dutta, National University of Singapore, Singapore

The article evaluates the feasibility of extending agile principles to 
larger, dynamic, and possibly distributed software development projects by 
uncovering the theoretical basis for agile values and principles for 
achieving agility. The extant literature focuses mainly on one theory – 
complex adaptive systems – to support agile methods, although recent 
research indicates that the control theory and the adaptive structuration 
theory are also applicable. This article proposes that at least three 
other theories exist that are highly relevant: transaction cost economics, 
social exchange theory, and expectancy theory. By employing these 
theories, a rigorous analysis of the Agile Manifesto is conducted. Certain 
agile values and principles find theoretical support and can be applied to 
enhance agility dynamic projects regardless of size; some agile principles 
find no theoretical support while others find limited support. Based on 
the analysis and the ensuing discussion, the authors propose a framework 
with five dimensions of agility: process, design, people, outcomes, and 
adaptation.

CALL FOR PAPERS

Mission of JDM:

The Journal of Database Management (JDM) publishes original research on 
all aspects of database management, systems analysis and design, and 
software engineering. The primary mission of JDM is to be instrumental in 
the improvement and development of theory and practice related to 
information technology and management of information resources. The 
journal is targeted at both academic researchers and practicing IT 
professionals.

Coverage of JDM:

The Journal of Database Management (JDM) publishes three types of rigorous 
and high quality articles: research articles, research notes, and research 
reviews. Research articles are full innovative findings that make 
substantial theoretical and empirical contributions to knowledge in the 
field by using various theoretical and methodological approaches. Research 
notes are novel and complete but not as comprehensive as full research 
articles; they include exploratory studies and methodological articles. 
Research reviews are insightful and carefully crafted articles that 
conceptualize research areas, synthesize previous innovative findings, 
advance the understanding of the field, and identify and develop future 
research directions. Authors are welcome to submit manuscripts that 
qualify for any of the three categories.

Topics of interest to the journal include, but are not limited to, the 
following areas:

·       Agile systems development
·       Bio-informatics
