Lotus Domino/Notes is the chief choice of OAS developing and running platform with its powerful and flexible compound document database, abundant application development environment, complete email system, the integration without gap of Internet/Intranet and other trait.
The paper discusses the single organization more domain model,work mode,copy and routestructure,mail integration and the integration technology with which the OAS with C/S and B/S mode is set up,and puts forward the idea to integration the different database sourses,such as document databases and relational databases.
Also in the paper,the data object model which supports both document databases and relational databases is given,as the data transfer among Heterogeneous Datasource is one of the main problems in the OA system development.
Lotus Domino/Notes is a programming language with many merits. There are complex document databases, an abundant application development environment, a self contained E mail system , an integration about Internet/Intranet in Lotus Domino/Notes. But it is no more straight in designing IHC (Interface Between Human and Computer) than VB and Delphi programming languages.
This paper firstly introduces how to use the distributed object oriented technology to build an integrated platform model, which is used to integrate many kinds of relational databases and document databases. Secondly it takes Digital Archive Retrieval System (DARS) as an example to describe how these technologies have been used into the implement of the heterogeneous information integration platform. This paper also shows the general application framework, which is deployed in DARS.
The algorithm has been tested on the UW English Document Database I of the University of Washington and its performance has been evaluated by a suitable measure of segmentation accuracy.
Search operations and browsing facilities over an XML document database require special support at the physical level.
In this paper, which treats Swedish full text retrieval, the problem of morphological variation of query terms in the document database is studied.
These six combinations were compared to each other and to a baseline combination, where no attempt was made to counteract the problem of morphological variation of query terms in the document database.
