摘要

DataLens是一种编程接口规范，它使1-2-3等应用程序能够通过客户机-服务器模型访问外部数据源。DataLens由Lotus开发，旨在支持从决策支持和面向事务的应用程序到广泛的后端服务器和数据源的访问。访问协议的差异对应用程序及其最终用户都是透明的。该规范允许DataLens应用程序在需要时利用高级数据库服务器特性，而不要求所有数据源都提供这些特性。本文介绍了DataLens体系结构，它如何处理服务器功能的差异，以及它与其他异构数据访问方法的比较。

The Lotus DataLens approach to heterogeneous database connectivity

DataLens is a specification for a programming interface that enables applications such as 1-2-3 to access external data sources through the client-server model. Developed at Lotus, DataLens was designed to support access from both decision support and transaction-oriented applications to a broad spectrum of backend servers and data sources. Differences in access protocols are transparent to both the application and its end user. The specification permits DataLens applications to leverage advanced database server features if desired, without requiring that all data sources supply these features. This paper covers the DataLens architecture, how it copes with differences in server capabilities, and how it compares with other approaches to heterogeneous data access.<>
