工程预算数据库TYD－1．0系统的设计与开发

DEVELOPMENT OF TYD-1. 0 DATA BASE SYSTEM FOR BUDGET QUOTA

煤矿建设三大工程（矿、工、安）预算软件达到通用性、互换性和可移植性的关键在于抓住定额本结构、特征和用户要求等对定额进行分项和独立建库，为调用和减少冗余，用树型结构、链式存贮。

To achieve generalization, exchangeability and transplantability of budget software for mine construction, building and installation, it is important to set up a separate and independent data on the basis of structure, characteristics of quota book and requirements of the user. For the ease of call and decrease redundancy, a tree-structure and chain -storage method are introduced.
