multi-lingual database system to a multi-model database system is to provide true sharing of databases--an ample motivation for the effort. As a first step, in this thesis we investigate the methods which allow a CODASYL-DML user to access a functional database. B. SOME BACKGROUND MATERIAL In this section, some background material for the. Coming at this from the perspective of a database person, I find that front end developers try too hard to find ways to make databases fit their model rather than consider the most effective ways to use database which are not object oriented or functional but relational and using set-theory.
TM1 takes the concept of Excel and applies it at a robust database level – leveraging Manny Perez’s technological advancement known as the functional database. An easy way to think about a Functional Database is to imagine it as millions and millions of neatly ordered, compact spreadsheets. Traditionally, the design and implementation of a conventional database system begins and ends with the choice of a data model followed by the specification of a model-based data language.
Abstract. In this paper we present the design of an optimiser for the object-oriented database P/FDM. We explore the approach of using a navigational query language, based on Shipman's original Daplex language [Sh 81] for the optimisation. The advantage of this is that it fits the navigational style of querying very well, but it is also inspirationdayevents.com by: Proceedings of the Third International Conference on Data and Knowledge Bases Improving Usability and Responsiveness.

You keep us going and growing – with your support we will do even more. It is imperative that the interface maintain the look, feel and characteristics of the Functional data model.
The result is a set of programs, written in C, which implement a Functional/DAPLEX interface, thus a sixth interface, for the inspirationdayevents.com: William Aime. Demers and Jon Mark. Rogelstad.
The design and implementation of a functional interface for the attribute-based multi-lingual database system. By Sybil B. Mack Download PDF (4 MB)Author: Sybil B. Mack. DAPLEX is a data definition and manipulation language for database systems, grounded in a concept of data representation called the functional data model.
DAPLEX may be considered to be a syntactic embodiment of the functional data model. A fundamental goal of DAPLEX is to provide a conceptually natural database interface inspirationdayevents.com by: The functional model is also distinct from other similarly named concepts, including the DAPLEX functional database model, and functional language databases.
The functional model comprises multidimensional hierarchical consolidation, as is commonly found in. Publisher Summary This chapter presents the DAPLEX language and the underlying data model on which it is based. DAPLEX is a data definition and manipulation language for database systems, grounded in a concept of data representation called the functional data model.
My book is now out of print, but it is available here in its entirety in PDF form. Errata Sectionp We need an extra rule match us  E = E This accounts for the possibility that in the constructor rule (Section ) there may be some non-nullary constructors for which there are [ ]Cited by: Abstract.
Conventional database languages rely on the user specifying what relations are to be used when evaluating a query. Consequently they preclude queries which involve searching for unspecified connections or associations in the database. In this paper we present Hydra, a functional language with all the facilities to define, Cited by: 4.
Databases and Natural Language Interfaces. and can be used with any database system supporting SQL. Masque/sql is efficient, and can be easily configured using the built-in domaineditor. This book gives a practical approach to understanding implementations of non-strict functional languages using lazy graph reduction.
The book is intended to be a source of practical labwork material, to help make functional-language implementations `come alive’, by helping the reader to develop, modify and experiment with some non-trivial compilers.

Implementing databases. A functional language is used to construct a database manager that allows efficient and concurrent access to sbared data. In contrast to the locking mechanism found in conventional databases, the functional database niles data dependency to provide exdUl'iion.

Apr 11, · Functional Strategies: Functional Strategies Deals with a relatively restricted plan designed to achieve objectives in a specific functional area, allocation of resources among different operations within that functional area and coordination among different functional areas for optimal contribution to the achievement of the business and corporate level objectives.

It is shown how this language can be used in the role of data definition and, when combined with interface classes, in the definition of database interfaces.

Kilgour and Ghassan al-Qaimari The object-oriented paradigm has a number of widely recognised strengths when applied to data management, but the increased com- plexity of actual systems compared with their relational predecessors often means Cited by: DAPLEX may be considered to be a syntactic embodiment of the functional data model.
A fundamental goal of DAPLEX is to provide a conceptually natural database interface language. each functional area. The number of such functional areas depend on the type of business carried out by the organization. For determining this number, criticality of an area should be taken into account, that is, what kind of contribution a particular functional area makes in achieving organizational objectives.3/5(4).
Functional database model. The functional database model is used to support analytics applications such as financial planning and performance management. The functional database model, or the functional model for short, is different from but complementary to the relational model.
Abstract. Approved for public release; distribution is unlimitedConventional approaches to the design and implementation of database systems have been based upon the premise of a single data model with its model-based data language, thus restricting the database system to transactions based solely on a specific model and written in a specific data inspirationdayevents.com: Harry Jr.
