The first issue is whether records in a database correspond to records in a programming language or to a distinct type such as tuple. The second issue is what facilities are provided to define the interface between an application program and a database.\u0000 The discussion below is based on our research on the RIGEL database programming language [Rowe 79, 80a]. RIGEL is a block-structured language with constructs for accessing relational databases, a module construct for data abstraction, and an exception-handling mechanism. The first implementation of the language has recently been completed and is being distributed.","PeriodicalId":347815,"journal":{"name":"Workshop on Data Abstraction, Databases and Conceptual Modelling","volume":"9 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120857233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first one is that of the user, who is interested in the external properties of a certain structure, more precisely, its noticeable behavior in response to outside effects (queries, requests for modifications, etc.). The second viewpoint is that of the language designer, who is in search of a small number of basic objects and building mechanisms which will allow for the description of complex objects in terms of simpler ones. The last view is that of the implementor, who must find efficient representations for the constructs thus described.\u0000 Based on this remark, a three-level description of data structures has been used by the author in previous work [6, 7, 8].

PIE is a subsystem that extends Smalltalk's descriptive power by supporting the creation, storage, retrieval and manipulation of network structures (GoldsteinBobrow80a,b,c; BobrowGoldstein80). These networks have been employed to represent software, documentation, electronic mail, calendars, people, addresses, bibliographic references and other items that together comprise the personal information space of a user of an office information system. By employing a common network representation, PIE supports an integrated environment for software development and office-related tasks. PIE has been developed collaboratively with Dan Bobrow, and is presently being used on an experimental basis by a small community at Xerox PARC.\u0000 Smalltalk represents entities in the external world as objects. An object has a state—i.e. an assignment of values to a set of state variables—and a class. The class of an object defines the behavior of the object in terms of a set of methods. Thus the class is a generic description of a collection of objects, while the objects associated with a class provide a particular description of the state of individual instances.","PeriodicalId":347815,"journal":{"name":"Workshop on Data Abstraction, Databases and Conceptual Modelling","volume":"609 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116396539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We assume that the workshop is dedicated to removing the boundaries between these three fields in order to shape research and development of common interest. While enthusiastically supporting this objective, we believe that each area has a unique perspective and emphasis worth preserving. The three fields can truly benefit from each other only if each one appreciates the diversity of these research viewpoints. In this spirit we describe a research project on Abstract Data Models conducted by the Institute for Computer Sciences and Technology (ICST) of the National Bureau of Standards (NBS). Before doing so, however, we wish to discuss from our perspective both some problems that database management shares with the areas of artificial intelligence and programming languages, and some possible mathematical solutions to these problems.","PeriodicalId":347815,"journal":{"name":"Workshop on Data Abstraction, Databases and Conceptual Modelling","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114397430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resulting description is a set of axioms in a FOPC. If the world is dynamic, one usually augments the description with the notion of time or state, in which case axioms can be divided naturally into “general laws” (heretofore constraints) holding in all states, and state-specific “facts”. Given states, one then also has the ability to describe state transitions (events) as predicates on pairs of states or, as shown below, as objects in their own right.","PeriodicalId":347815,"journal":{"name":"Workshop on Data Abstraction, Databases and Conceptual Modelling","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121554595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each of the fields has contributed four major concepts to our modeling approach.\u0000 From the Data Base field, we have adopted the idea of a single global model (data base) which defines the state of the system. Fully associative relations among typed atomic objects (no internal structure) constitute the entire state description. An information model (query language) is defined for extracting information from the state (such as one or all objects satisfying some description, or the truthfulness of some proposition). Finally, the model is updated via transactions, so that either the entire operation is completed successfully, or the state is unchanged.","PeriodicalId":347815,"journal":{"name":"Workshop on Data Abstraction, Databases and Conceptual Modelling","volume":"6 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120981967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
