seamless database
解釋
無縫數據庫-
The system realizes multiple serial port communication and management by way of multi - port serial board ( 2 ) use the database technology to manage and manipulate the physics information data of nc tool. the basic information management system, the nc program auto - create system, the simulation of cutter working and dnc communication program are integrated to one system. it realizes the offline programming and controls of no - punched tape, helps to cut short the supplementary cutting time and improves the efficiency of to program and machine tools and realizes the separation and seamless connection of program and manufacture
本課題以硬體為輔助手段，以軟體為主要手段實現了以下功能：以串口擴展卡來實現網路中多臺數控機床的通信和管理；使用數據庫技術對數控機床的物理信息進行管理和操作，將數控機床基礎信息管理系統、 nc程序自動生成模塊、刀具加工軌跡模擬模塊和dnc通信介面模塊集成為一體，實現了數控加工的離線編程和數控系統的無帶控制，提高了編程效率、質量，縮短加工輔助時間，提高了機床的效率，既實現了編程和加工的分離，又達到它們之間的無縫連接。 -
According the customer ' s needing, the author makes a general design of the cadastral information system ' s function and makes full use of spatial database workflow and gis, then gives us a new different method based on component technology, which uses vb language and inserts map - objects in notes so that makes full use of the objects - attribute and method to realize the seamless integration designing of oa and gis. this method remedies the defect of traditional integration and reduces the develop construction cycle and cost, making gis as an important part participating in the daily cadastral oa system
利用vb編程技術，在notes環境下嵌入mapobjects組件，利用mapobjects組件提供的對象屬性、操作進行開發，以實現gis與oa的無縫集成設計，彌補了傳統gis與oa集成方案的缺陷，真正地做到界面功能和數據的無縫集成和圖文一體化，縮短了開發周期，降低了開發成本，使gis技術作為一個重要的組成部分，真正參與到日常的地籍辦公自動化系統中。 -
The paper researches data property, principle standard and step of spatial database and discusses framework management of spatial database and analyses key technology that are seamless integration of spatial database, metadata structure, spatial database copy and spatial data update adopting spatial database basic theory combination instance about establishing of beijing land source and house management information system
摘要採用空間數據庫的基本理論，結合北京市國土資源與房屋管理信息系統中建庫的實例，研究了空間數據建庫的數據性質，空間數據建庫的原則、標準和步驟；探討了空間數據庫的組織管理；分析了空間數據建庫數據的無縫集成、元數據的組織、空間數據庫增量備份和增量更新等關鍵技術。 -
As we known, there is a big performance gap of data access among each layer in three layer storage system. so in order to integrate them into a seamless storage system and support database system well, we must design a query processing method which fit the hardware characteristic of three layer storage system
由於三級存儲系統各存儲層次在數據存取性能方面存在巨大差異，為了使三級存儲系統各存儲層次「無縫」地連接在一起並很好地融入到數據庫系統中，就必須研究設計出符合三級存儲系統硬體特點的高效的查詢處理方法。 -
The author also put forward the construction of ugis seamless database based on administrative district about how to construct the database of big - scale ugis. this method breaks the traditional method of construction of spatial data, makes the users put their attention to the query based on administrative and expresses the real world better
基於行政單元的數據組織打破了圖幅的界限，把數據按行政單元進行存儲，將用戶的注意力轉移到行政單元的查詢、檢索和分析上，無縫數據庫的實現更好地模擬了現實世界，提高了查詢、檢索的質量和速度。
