Abstract. Geographic information (geo-data; i.e., data with a spatial component.) is being used for civil, political, and commercial applications. Modeling geo-data can be involved due to its often very complex structure, hence placing high demands on the modeling language employed. Many geo-applications would greatly benefit from the possibility of integrating existing geo-databases. Data integration is a notoriously hard problem, and integrating geo-databases in practice often adds the extra requirement that the integration should result in a real-time system.

This paper provides a case study and a design method for real-time integration of geo-databases based on the ORM modeling language. We will show that the use of ORM is superior to competing approaches, and that the so-called ORM federation procedure will yield correct design of integrated geo-databases.

Towards Using Semantic Decision Tables for Organizing Data Semantics

Yan Tang, Vrije Universiteit Brussel (Belgium)

Abstract. In the ITEA2 Do-It-Yourself Smart Experiences project (DIY-SE), we are required to design an ontology-based ambient computing environment to support users to DIY their personalized solutions. In this paper, we illustrate how to manage data semantics using Semantic Decision Table (SDT). We use a simple rule writing language called Decision Commitment Language (DECOL) to store the SDT commitments. Semantic Decision Rule Language (SDRule-L), which is an extension to Object Role Modelling (ORM), is used to graphically represent DECOL. In this paper, we will demonstrate how SDT, together with SDRule-L and DECOL, are used by both technical and non-technical end users.

A Basic Characterization of Relation Migration

C. Maria Keet, Free University of Bozen-Bolzano (Italy)
Alessandro Artale, Free University of Bozen-Bolzano (Italy)

Abstract. Representing and reasoning over evolving objects has been investigated widely. Less attention has been devoted to the similar notion of relation migration, i.e., how tuples of a relation (ORM facts) can evolve along time. We identify different ways how a relation can change over time and give a logicbased semantics to the notion of relation migration to capture its behaviour. We also introduce the notion of lifespan of a relation and clarify the interactions between object migration and relation migration. Its use in graphical conceptual data modelling is illustrated with a minor extension to ORM2 so as to more easily communicate such constraints with domain experts.

P:14 A proposal for Folding in ORM tool diagrams

A Proposal for Folding in ORM Diagrams

Tony Morgan, INTI International University (Malaysia)

Abstract. Object Role Modeling (ORM) can be used to produce conceptual models of any scale. Although small examples are often used to illustrate specific points, it is equally possible to produce large models covering extensive business domains. To help users navigate around a large model, the ORM diagram is typically split over several virtual pages. This gives a fairly coarse granularity and it is difficult for users to change the page structure to meet some temporary viewing need.

This paper describes an alternative approach that allows objects of lesser interest to be temporarily 'folded' away and 'unfolded' when required. The folding and unfolding can be dynamically controlled by the user, but operates under the control of specific algorithms. Some possible algorithms are discussed and illustrated with examples, and a number of usability issues are raised.

Subtyping and Derivation Rules in Fact-Based Modeling

Peter Bollen, Maastricht University (The Netherlands)

Abstract. In this paper we will reflect on the derivation rule modeling concept and we will investigate how the definition of derivation rules is related to the subtypes and the subtype defining fact types in a conceptual schema.

We propose the concept of ‘derivation-logic induced' classifying fact types and what advantages this can have in terms of the creation and maintainability of conceptual schemas.

Abstract. Optimization of modern businesses is becoming increasingly dependent on business intelligence and rule-based software to perform predictive analytics over massive data sets and enforce complex business rules. This has led to a resurgence of interest in datalog, because of its powerful capability for processing complex rules, especially those involving recursion, and the exploitation of novel data structures that provide performance advantages over relational database systems.

ORM 2 is a conceptual approach for fact oriented modeling that provides a high level graphical and textual syntax to facilitate validation of data models and complex rules with nontechnical domain experts. Datalog^LB is an extended form of typed datalog that exploits fact-oriented data structures to provide deep and highly performant support for complex rules with guaranteed decidability. This paper provides an overview of recent research and development efforts to extend the Natural ORM Architect (NORMA) software tool to map ORM models to Datalog^LB.

Abstract: The integration of a number of facets of reference data, metadata, data models, governance, and services continues to grow and become more important and pragmatic to businesses. Since 2004 a growing number of companies have heavily invested many resources into pulling together related components into more and more unified approaches that attempt to help solve the problem of managing data. More specifically, Master Data Management and closely related components to MDM such as metadata management systems (MMS) and business glossaries are critical to delivering a complete organically grown product with a single, clean architecture.

This paper will describe a scenario of how Object Role Modeling could be leveraged to provide the enterprise with a fact based conceptual model that is integrated with an MDM's business glossary.

The ultimate goal is to provide a common understanding of the business at a conceptual level and at the same time deliver on the capability of providing a comprehensive and deep ‘where used' capability for the delivery of a variety of common functions desperately need by companies today. This scenario is based on the evaluation of three major MDM vendors during the past year by Boston Scientific Corporation.

Literacy and Data Modeling

Ron McFadyen, University of Winnipeg (Canada)
Susan Birdwise, University of Manitoba (Canada)

Abstract. Reading and assimilating information in documents is a necessity of modern life. Literacy was once considered to be just the ability to read and write; but the term has evolved today to mean the ability to understand and employ printed information in daily activities, at home, at work and in the community. As used today, literacy involves many scales including prose, document, and quantitative; literacy testing involves the completion of several tasks designed for each scale.

What is of interest to us here is the concept of document literacy and how that fits into the development of an information model. When developing an information system the data analyst designs a conceptual schema using a process such as the Conceptual Schema Development Process. In this paper we focus on non-continuous matrix documents as known for document literacy and their counterparts in Object-Role Modeling's conceptual model.

Abstract. The use of patterns in a design process, including data modeling, is an attempt to create a better solution to a problem. We propose the use of data model patterns, organized in a pattern language, and based on Fully Communication Oriented Information Modeling (FCO-IM) as the modeling approach, as a standard to produce high quality data models. We introduce the concept of Information Grammar for Pattern (IGP) which works as a kind of template to generate FCOIM's Information Grammar (IG). IGP is also used to define the relations among patterns. Based on how they are abstracted, we also define 3 types of IGP. The IGP provides the basic idea for the pattern language of data model patterns based on the relations among patterns.

A Fact-Based Meta Model for Standardization Documents

Peter Bollen, Maastricht University (The Netherlands)

Abstract. Recently, the OMG has been working on developing a new standard for a Business Process Model and Notation (BPMN). This standard development has resulted in documents that contain the latest approved version of a standard or a standard proposal that can be amended. Such a standard document also serves as a specification for BPMN modeling tool. In this paper we show how a fact-based approach can improve the completeness and maintenance of such a specification.

A Metamodel for Master Data

Baba Piprani, MetaGlobal Systems (Canada)
Suneil Dham, Office of the Superintendent of Financial Institutions (Canada)

Abstract. The term ‘Master Data' brings up different interpretations and connotations, especially with vendors espousing the "single version of the truth". Is there a single version of the truth? Practical realities suggest that we need to continue to live with existing versions - at least until the "single version" is reached. So how do we handle the co-existence of "multiple versions" of the truth? This paper examines a metamodel that defines what master data is, the types of master data, and criteria for determining master data.

The metamodel visits master data administration, privileges and master data services including change management, metadata migration and data migration for master data is also reviewed. The impact of changes to an enterprise going the master data route, along with the emphasis to influence future management direction is also examined. Several administration aspects make use of established ISO standards in metadata IS:11179-3 and IS:19763.

P:02 Using Object Role Modeling in a Service-oriented Data Integration Project

Using Object Role Modeling in a Service-oriented Data Integration Project
Presentation of a paper by: Ilkka Melleri, Aalto University School of Science and Technology (Finland)

Abstract. Communication between business and IT experts is challenging, because business requirements are often specified in subjective and vague terms compared to the formality needed for technical implementation. In the service-oriented architectures (SOA) context this issue is especially important, because the value proposition of SOA is based on a business awareness of the systems. In this paper we address this challenge by using the Object Role Modeling (ORM) method in a case study focusing on a service-oriented data integration project. The results of this study indicate that the automatic verbalizations combined with the automatic XML Schema generation of the ORM models could be useful in SOA integration projects to support the collaboration between the business and IT experts. The main concerns that were identified relate to the change management of the ORM models, managing the high level of detail in the models and the workload if no adequate automation is provided.
