  • ENTITY-RELATIONSHIP MODELING of SPATIAL DATA for GEOGRAPHIC INFORMATION SYSTEMS Hugh W
    ENTITY-RELATIONSHIP MODELING OF SPATIAL DATA FOR GEOGRAPHIC INFORMATION SYSTEMS Hugh W. Calkins Department of Geography and National Center for Geographic Information and Analysis, State University of New York at Buffalo Amherst, NY 14261-0023 Abstract This article presents an extension to the basic Entity-Relationship (E-R) database modeling approach for use in designing geographic databases. This extension handles the standard spatial objects found in geographic information systems, multiple representations of the spatial objects, temporal representations, and the traditional coordinate and topological attributes associated with spatial objects and relationships. Spatial operations are also included in this extended E-R modeling approach to represent the instances where relationships between spatial data objects are only implicit in the database but are made explicit through spatial operations. The extended E-R modeling methodology maps directly into a detailed database design and a set of GIS function. 1. Introduction GIS design (planning, design and implementing a geographic information system) consists of several activities: feasibility analysis, requirements determination, conceptual and detailed database design, and hardware and software selection. Over the past several years, GIS analysts have been interested in, and have used, system design techniques adopted from software engineering, including the software life-cycle model which defines the above mentioned system design tasks (Boehm, 1981, 36). Specific GIS life-cycle models have been developed for GIS by Calkins (1982) and Tomlinson (1994). Figure 1 is an example of a typical life-cycle model. GIS design models, which describe the implementation procedures for the life-cycle model, outline the basic steps of the design process at a fairly abstract level (Calkins, 1972; Calkins, 1982).

  • Metamodeling the Enhanced Entity-Relationship Model
    Metamodeling the Enhanced Entity-Relationship Model Robson N. Fidalgo1, Edson Alves1, Sergio España2, Jaelson Castro1, Oscar Pastor2 1 Center for Informatics, Federal University of Pernambuco, Recife(PE), Brazil {rdnf, eas4, jbc}@cin.ufpe.br 2 Centro de Investigación ProS, Universitat Politècnica de València, València, España {sergio.espana,opastor}@pros.upv.es Abstract. A metamodel provides an abstract syntax to distinguish between valid and invalid models. That is, a metamodel is as useful for a modeling language as a grammar is for a programming language. In this context, although the Enhanced Entity-Relationship (EER) Model is the ”de facto” standard modeling language for database conceptual design, to the best of our knowledge, there are only two proposals of EER metamodels, which do not provide a full support to Chen’s notation. Furthermore, neither a discussion about the engineering used for specifying these metamodels is presented nor a comparative analysis among them is made. With the aim at overcoming these drawbacks, we show a detailed and practical view of how to formalize the EER Model by means of a metamodel that (i) covers all elements of the Chen’s notation, (ii) defines well-formedness rules needed for creating syntactically correct EER schemas, and (iii) can be used as a starting point to create Computer Aided Software Engineering (CASE) tools for EER modeling, interchange metadata among these tools, perform automatic SQL/DDL code generation, and/or extend (or reuse part of) the EER Model. In order to show the feasibility, expressiveness, and usefulness of our metamodel (named EERMM), we have developed a CASE tool (named EERCASE), which has been tested with a practical example that covers all EER constructors, confirming that our metamodel is feasible, useful, more expressive than related ones and correctly defined.

  • A Logical Design Methodology for Relational Databases Using the Extended Entity-Relationship Model
    A Logical Design Methodology for Relational Databases Using the Extended Entity-Relationship Model TOBY J. TEOREY Computing Research Laboratory, Electrical Engineering and Computer Science, The University of Michigan, Ann Arbor, Michigan 48109-2122 DONGQING YANG Computer Science and Technology, Peking Uniuersity, Beijing, The People’s Republic of China JAMES P. FRY Computer and Information Systems, Graduate School of Business Administration, The University of Michigan, Ann Arbor, Michigan 48109-1234 A database design methodology is defined for the design of large relational databases. First, the data requirements are conceptualized using an extended entity-relationship model, with the extensions being additional semantics such as ternary relationships, optional relationships, and the generalization abstraction. The extended entity- relationship model is then decomposed according to a set of basic entity-relationship constructs, and these are transformed into candidate relations. A set of basic transformations has been developed for the three types of relations: entity relations, extended entity relations, and relationship relations. Candidate relations are further analyzed and modified to attain the highest degree of normalization desired. The methodology produces database designs that are not only accurate representations of reality, but flexible enough to accommodate future processing requirements. It also reduces the number of data dependencies that must be analyzed, using the extended ER model conceptualization, and maintains data

  • Gis Data Models
    GIS DATA MODELS CONCEPTUAL MODEL OF SPATIAL INFORMATION 1. Introduction GIS does not store a map in any conventional sense, nor it stores a particular image or view of geographic area. Instead, a GIS stores the data from which we can draw a desired view to suit a particular purpose known as geographic data. There are two types of data in GIS; spatial data and non-spatial data (Attribute data). Non-spatial data include information about the features. For example, name of roads, schools, forests etc., population or census data for the region concerned etc. Non-spatial or attribute data is that qualifies the spatial data. It describes some aspects of the spatial data, not specified by its geometry alone. A geographical information system essentially integrates the above two types of data and allows user to derive new data for planning. Spatial models are important in that way in which information is represented affects the type of analysis that can be performed and the type of graphic display that can be performed and the type of analysis that can be obtained. In GIS systems there is a major distinction between what are usually referred to as vector GIS and raster GIS. These two approaches to spatial data processing, often to be found in the same GIS package, reflect two different methods of spatial modeling: the former focusing on discrete objects that are to be described, and the latter concerned primarily with recording what is to be found at a predetermined set of locations that may be grid cells or points.

  • The Layman's Guide to Reading Data Models
    Data Architecture & Engineering Services The Layman’s Guide to Reading Data Models A data model shows a data asset’s structure, including the relationships and constraints that determine how data will be stored and accessed. 1. Common Types of Data Models Conceptual Data Model A conceptual data model defines high-level relationships between real-world entities in a particular domain. Entities are typically depicted in boxes, while lines or arrows map the relationships between entities (as shown in Figure 1). Figure 1: Conceptual Data Model Logical Data Model A logical data model defines how a data model should be implemented, with as much detail as possible, without regard for its physical implementation in a database. Within a logical data model, an entity’s box contains a list of the entity’s attributes. One or more attributes is designated as a primary key, whose value uniquely specifies an instance of that entity. A primary key may be referred to in another entity as a foreign key. In the Figure 2 example, each Employee works for only one Employer. Each Employer may have zero or more Employees. This is indicated via the model’s line notation (refer to the Describing Relationships section). Figure 2: Logical Data Model Last Updated: 03/30/2021 OIT|EADG|DEA|DAES 1 The Layman’s Guide to Reading Data Models Physical Data Model A physical data model describes the implementation of a data model in a database (as shown in Figure 3).

  • Database Reverse Engineering Tools
    7th WSEAS Int. Conf. on SOFTWARE ENGINEERING, PARALLEL and DISTRIBUTED SYSTEMS (SEPADS '08), University of Cambridge, UK, Feb 20-22, 2008 Database Reverse Engineering Tools NATASH ALI MIAN TAUQEER HUSSAIN Faculty of Information Technology University of Central Punjab, Lahore, Pakistan Abstract: - Almost every information system processes and manages huge data stored in a database system. For improvement and maintenance of legacy systems, the conceptual models of such systems are required. With the growing complexity of information systems and the information processing requirements, the need for database reverse engineering is increasing every day. Different Computer Assisted Software Engineering (CASE) tools have been developed as research projects or as commercial products which reverse engineer a given database to its conceptual schema. This paper explores the capabilities of existing CASE tools and evaluates to which extent these tools can successfully reverse engineer a given database system. It also identifies the constructs of a conceptual model which are not yet supported by the database reverse engineering tools. This research provides motivation for software engineers to develop CASE tools which can reverse engineer the identified constructs and can therefore improve the productivity of reverse engineers. Key-Words: - Database reverse engineering, CASE tools, Conceptual schema, ER model, EER model 1 Introduction (OMT), and Entity-Relationship (ER) Database Reverse Engineering (DBRE) is a model. ER model is widely used as a data process of extracting database requirements modeling tool for database applications due from an implemented system. Traditionally, to its ease of use and representation.
