Reasoning is about how we go about the act of thinking using this knowledge. System based object-oriented languages, like C++, Java and C#, have data definitions called classes for describing the composition and behaviour of modeled entities.

An object-oriented logic-based language for queries and updates by Dimitra Vista Download PDF EPUB FB2

In most object-oriented databases, as opposed to value-oriented databases, data are accessed by a programming language instead of a declarative query language. End users do not have a simple tool to perform their queries.

This paper is concerned with the definition of. Query Language Approach Based on the Deductive Object-Oriented Database Paradigm Article in Information and Software Technology 42(11) August. The architecture of the federation taken here contains two local data models: an object-oriented data model (e.g., O 2 [17]) and a logic-based model (e.g., Logres [6]).

A canonical data model which combines the concepts used in object and logic-based models is needed to achieve such interoperability. XPathLog is a logic-based language for manipulating and integrating XML data.

It extends the XPath query language with Prolog-style variables. Due to the close relationship with XPath, the Author: Wolfgang May. Abstract. We present a language Noodle in which to specify declarative queries in an object-oriented database system. The language models object-identity, classes, relations, views, inheritance, complex objects, and methods, in addition to logical rules, and Cited by: Abstract.

We report on our experience in designing and prototyping ROLL, a logical query language under which object-oriented databases conforming to the model defined in [14, 15] can be seen as deductive object-oriented main contribution of ROLL is to demonstrate the possibility of pursuing for the object-oriented case the same research strategy used in the last decade to extend Cited by: 5.

In my experience, most people without a programming background find different paradigms more or less difficult in approximately the order: * Procedural (Lisp, Perl, etc) * Object Oriented (Lisp, Perl, Ruby, etc) * Functional (Haskell, Lisp, etc) *.

F-logic (frame logic) is a knowledge representation and ontology language.F-logic combines the advantages of conceptual modeling with object-oriented, frame-based languages and offers a declarative, compact and simple syntax, as well as the well-defined semantics of a logic-based language. The power of lazy evaluation will make the program run faster because it only provides what we really required for the queries result.

Suppose we have a large amount of data and want to filter it by a specific condition, such as showing only the data that contains the word Name. ROL (Rule-based Object Language) [Liu ; a] is a recently proposed object-oriented deductive language implemented at the University of Regina [Liu et al.

It is based on F-logic and solves some of the problems of F-logic discussed above. This volume is the proceedings of the Second International Conference on Deductive and Object-Oriented Databases (DOOD).

During the last decade, deductive and object-oriented systems have received a great deal of attention, but for the most part these two fields were evolving independently of.

Data oriented programming is simply a programming language with database, you can create tables and queries, and program to manipulate the stored data on it, example of data oriented language are SQL, DBase and Visual Foxpro. Chapter 12 is an overview of research prototypes for integrating relational databases and logic programming.

The book also contains an extensive bibliography and an index. The book contains a large number of examples and exercises. It is suitable as a textbook at the advanced An object-oriented logic-based language for queries and updates book or beginning graduate level.

Logic programming is a programming paradigm which is largely based on formal program written in a logic programming language is a set of sentences in logical form, expressing facts and rules about some problem domain.

Major logic programming language families include Prolog, answer set programming (ASP) and all of these languages, rules are written in the form of clauses. The Representation Language. Regarding formalization, the first aspect is to choose a suitable logic-based language, which ought to be the optimal choice based on the required language features and automated reasoning requirements (if any), that, in turn, ought to follow from the overall purpose of the ontology (due to computational limitations), if there is a purpose at all [Kee10a].

We use conjunctive queries as a vehicle to introduce many of the main issues in query languages, which will recur throughout the book. More powerful languages are then obtained by gradually enriching the conjunctive queries by adding negation, recursion, and finally, negation and recursion : $ providing a user interface enabling a user to define rules against the predicate logic facts in the corpus, and further enabling the user to execute queries against the corpus and any result set in the corpus, the queries being written in at least one of a natural language or a predicate logic notation, wherein the predicate logic notation includes an artificial intelligence language notation;Cited by: Developing distributed database applications using TSL.- Prints of the 17th Century in a distributed digital library system.- OASIS v2: A class definition language.- Design and implementation of object-oriented views.- A visual object-oriented query language for geographic information systems.-Price: $ FLORA-2 is a logic-based object-oriented language for building knowledge-intensive applications.

In the remainder of the article, I focus on some of the more significant aspects contributed by logic in databases: (1) a formalization of what constitutes a database, a query, and an answer to a query; (2) a realization that logic programming extends relational databases; (3) a clear understanding of the semantics of large classes of databases that include alternative forms of negation as.

Includes a graphical client that builds upon the logic-based features of the server. The data model is O-Telos. relational, and object oriented. These include primarily a data definition language (DDL) for specifying the structural aspects of the data and a data manipulation language (DML) for accessing and updating it.

The separation of the logical from the physical has resulted in an extraordinary increase in database usability and programmer. A multilevel secure object-oriented data model (using the ORION data model) is proposed for which mandatory security issues in the context of a database system is discussed.

In particular the following issues are dealt with: (1) the security policy for the system, (2) handling polyinstantiation, and (3) handling the inference problem. A set of security properties that has been established in. This document contains information relevant to 'XML and Query Languages' and is part of the Cover Pages resource.

For example, the separation between logical and physical means that the system must compile queries and updates directed to the logical representation into “real” programs. Indeed, the use of the relational model became widespread only when query optimization techniques made it feasible.

The Datalog package contains a lightweight deductive database system. Queries and database updates are expressed using Datalog—a declarative logic language in which each formula is a function-free Horn clause, and every variable in the head of a clause must appear in the body of the clause. The use of Datalog syntax and an implementation based on tabling intermediate results, ensures that.

The core idea of this book is that object-oriented technology is a generic technology whose various technical aspects could be presented in a unified and consistent framework. This applies to both practical and formal aspects of object-oriented technology.

The approach in the book is based on typed technologies. The core notions. 9 OO base language, extended with logical constructs, 9 two base languages (OO and logic), interfaced, 9 logic base language, extended with OO constructs.
