  • 26. Relational Databases and Beyond
    26 Relational databases and beyond M F WORBOYS This chapter introduces the database perspective on geospatial information handling. It begins by summarising the major challenges for database technology. In particular, it notes the need for data models of sufficient complexity, appropriate and flexible human-database interfaces, and satisfactory response times. The most prevalent current database paradigm, the relational model, is introduced and its ability to handle spatial data is considered. The object-oriented approach is described, along with the fusion of relational and object- oriented ideas. The applications of object-oriented constructs to GIS are considered. The chapter concludes with two recent challenges for database technology in this field: uncertainty and spatio-temporal data handling. 1 INTRODUCTION TO DATABASE SYSTEMS variation in their requirements. Data should be retrieved as effectively as possible. It should be 1.1 The database approach possible for users to link pieces of information Database systems provide the engines for GIS.

Keywords: Clustering, unsupervised learning, factor graphs, kernel density estimation Abstract This thesis addresses two challenges in extracting patterns from social data generated by modern sensor systems and electronic mechanisms. First, that such data often combine spatial, temporal, and relational evidence, requiring models that properly utilize the regularities of each domain. Sec- ond, that data from open-ended systems often contain a mixture between entities and relationships that are known a priori, others that are explicitly detected, and still others that are latent but significant in interpreting the data.

  • A Solution to the Object-Relational Mismatch
    Universidade do Minho Escola de Engenharia Miguel Esteves CazDataProvider: A solution to the object-relational mismatch Outubro de 2012 Universidade do Minho Escola de Engenharia Departamento de Informática Miguel Esteves CazDataProvider: A solution to the object-relational mismatch Dissertação de Mestrado Mestrado em Engenharia Informática Trabalho realizado sob orientação de Professor José Creissac Campos Outubro de 2012 To my parents... \Each pattern describes a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice." Christopher Alexander Abstract Today, most software applications require mechanisms to store information persistently. For decades, Relational Database Management Systems (RDBMSs) have been the most common technology to provide efficient and reliable persistence. Due to the object-relational paradigm mismatch, object oriented applications that store data in relational databases have to deal with Object Relational Mapping (ORM) problems. Since the emerging of new ORM frameworks, there has been an attempt to lure developers for a radical paradigm shift. However, they still often have troubles finding the best persistence mechanism for their applications, especially when they have to bear with legacy database systems. The aim of this dissertation is to discuss the persistence problem on object oriented applications and find the best solutions. The main focus lies on the ORM limitations, patterns, technologies and alternatives. The project supporting this dissertation was implemented at Cachapuz under the Project Global Weighting Solutions (GWS). Essentially, the objectives of GWS were centred on finding the optimal persistence layer for CazFramework, mostly providing database interoperability with close-to-Structured Query Language (SQL) querying.

  • Files Versus Database Systems - Architecture - E-R
    UNIT I Introduction - Historical perspective - Files versus database systems - Architecture - E-R model- Security and Integrity - Data models. INTRODUCTION Data : • Data is stored facts • Data may be numerical data which may be integers or floating point numbers, and non-numerical data such as characters, date and etc., Example: The above numbers may be anything: It may be distance in kms or amount in rupees or no of days or marks in each subject etc., Information : • Information is data that have been organized and communicated in a coherent and meaningful manner. • Data is converted into information, and information is converted into knowledge. • Knowledge; information evaluated and organized so that it can be used purposefully. Example: The data ( information) which is used by an organization – a college, a library, a bank, a manufacturing company – is one of its most valuable resources. Database : • Database is a collection of information organized in such a way that a computer program can quickly select desired pieces of data. 1 Database Management System (DBMS) : • A collection of programs that enables you to store, modify, and extract information from a database. • A collection of interrelated data and a set of programs to access those data. • The primary goal of a DBMS is to provide an environment that is both convenient and efficient to use in retrieving and storing database information. HISTORY OF DATABASE SYSTEMS : Techniques for data storage and processing have evolved over the years. 1950’s and early 1960’s : - Magnetic tapes were developed for data storage. - Processing of data consisted of reading from one or more tapes and writing data to a new tape.

  • 2.5.- the Standard Language SQL
    2.5.- The standard language SQL •SQL (Structured Query Language) is a standard language for defining and manipulating (and selecting) a relational database. • SQL includes: • Features from Relational Algebra (Algebraic Approach). • Features from Tuple Relational Calculus (Logical Approach). • The most extended version nowadays is SQL2 (also called SQL’92). – Almost all RDBMSs are SQL2 compliant. – Some features from SQL3 (and some of the upcoming SQL4) are being included in many RDBMSs. 1 2.5.1.- SQL as a data definition language (DDL) SQL commands for defining relational schemas: • create schema: gives name to a relational schema and declares the user who is the owner of the schema. • create domain: defines a new data domain. ORACLE • create table: defines a table, its schema and its associated constraints. ORACLE • create view: defines a view or derived relation in the relational schema. • create assertion: defines general integrity constraints. ORACLE • grant: defines user authorisations for the operations over the DB objects. All these commands have the opposite operation (DROP / REVOKE) and modification (ALTER). 2 2.5.1.1.- Schema Definition (SQL) create schema [schema] [authorization user] [list_of_schema_elements]; A schema element can be any of the following: • Domain definition. • Table definition. • View definition. • Constraint definition. • Authorisation definition. Removal of a relational schema definition: drop schema schema {restrict | cascade}; 3 2.5.1.2.- Domain Definition (SQL) create domain domain [as] datatype [default

  • Ict: Computer Programming April 27
    LA IMMACULADA CONCEPCION SCHOOL SENIOR HIGH SCHOOL GRADE 12 – ICT: COMPUTER PROGRAMMING APRIL 27 – 30, 2020 Topic: Relational Data Model and Relational Database Constraints Data models that preceded the relational Model include the hierarchical and network models. They were proposed in the 1960s and were implemented in early DBMSs during the late 1960s and early 1970s. Because of their historical importance and existing user base for these DBMS. Relational Model Concepts The relational model represents the database as a collection of relations. Informally, each relation resembles a table of values or, to some extent, a flat file of records. It is called a flat file because each record has a simple linear or flat structure. For example, the database of files is similar to the basic relational model representation. However, there are important differences between relations and files. When a relation is thought of as a table of values, each row in the table represents a collection of related data values, a row represents a fact that typically corresponds to a real-world entity or relationship. Table name and column names are used to help to interpret the meaning of the values in each row. For example, the first table is called STUDENT because each row represents facts about a particular student entity. The column names- Name, Student_Number, Class and Major-specify how to interpret the data values in each row, based on the column each value is in. all values in a column are of the same data type. In the formal relational model terminology, a row is called a tuple, a column header is called an attribute, and the table is called a relation.
