Functional programming in a basic database course [chapter]

Pieter Koopman, Vincent Zweije
1995 Lecture Notes in Computer Science  
We used a functional language for its high level of abstraction and the automatic memory management which make writing a simple database management system considerably easier.  ...  This paper describes why and how a functional programming language was used in an introductory database course.  ...  After writing a preliminary program in a functional language the students make four exercises related to databases: an ad-hoc database, an interpreter for relational algebra, an implementation of a sub-set  ...

Simple and safe SQL queries with c++ templates

Joseph (Yossi) Gil, Keren Lenz
2007 Proceedings of the 6th international conference on Generative programming and component engineering - GPCE '07  
Interaction with such a database is often done by letting the program construct strings with valid SQL statements, which are then sent for execution to the database engine.  ...  A library of templates and preprocessor directives effectively extends C++ with a little language representing an augmented relational algebra formalism.  ...  ARARAT, the system presented here, employs C++ templates mechanism to address the common problem of integrating a database language into a programming language.  ...

A Modal System of Algebras for Database Specification and Query/Update Language Support

Forouzan Golshani, T. S. E. Maibaum, M. R. Sadler
1983 Very Large Data Bases Conference  
Rather than iormaliaing general properties or database systems and derining abstract languages ror databases, in this paper we provide a formal system for reasoning about spdric properties  ...  We regard a database as a dynamic! object and use a system of modal logia similar to Hoare-style program logic ror its specification.  ...  These general operators, first order logic and the modal system, are a fixed specifioation language for database applications.  ...

Polymorphic type inference for the relational algebra in the functional database programming language neon

Lajos Nagy, Ryan Stansifer
2006 Proceedings of the 44th annual southeast regional conference on - ACM-SE 44  
A database programming language is a programming language extended with database operations.  ...  We present the functional database programming language Neon along with a polymorphic type inference algorithm that can infer a 'type formula', that is, a type together with type constraints, for any valid  ...  The functional nature of relational algebra makes it appealing to attempt to define a functional database programming language that synthesizes functional programming and relational algebra.  ...

PySBQL - Python-like query language constructed using stack base approach

Marta Roginska, Piotr Wisniewski
2007 Annales UMCS Informatica  
As a query language it is similar to SBQL proposed by Subieta [1, 2] . The PySBQL language is implemented in Monad -Object Oriented Database Management System.  ...  Contrary to the classical approach in query languages, semantics is defined using a common structure for programming languages -the Environment Stack (ENVS).  ...  It is taken directly form the Python language. Monad project Monad is an object oriented database management system based on the PySBQL language. Monad is a fully scalable programing platform.  ...

Hybrid applications over XML

Paolo Manghi, Fabio Simeoni, David Lievens, Richard Connor
2002 Proceedings of the fourth international workshop on Web information and data management - WIDM '02  
We discuss the design of a quasi-statically typed language for XML in which data may be associated with different structures and different algebras in different scopes, whilst preserving identity.  ...  For its original form of structural polymorphism, the language offers integrated support for the development of hybrid applications over XML, where data change form to reflect programming expectations  ...  In fact, the view of XML as a universal format for the exchange of data suggests that large part of that data will originate in standard programming languages and database systems.  ...

Abstract object types for databases [chapter]

H. -D. Ehrich, A. Sernadas, C. Sernadas
1988 Lecture Notes in Computer Science  
~ -There is a need for exploring the theoretical and methodological foundations of database design and development with the intention to achieve provably correct systems and higher levels of reusability  ...  In analogy to algebraic data type theory, we propose mathematical models for the basic notions of object, object type and abstract object type.  ...  An algebraic semantics for this language is outlined. As a byproduct, the Kripke interpretation structure for the invisaged logic of object behaviour is established.  ...
