隨著資料庫軟體與通訊工業的蓬勃發展,很多系統已經可以透過網路將資訊無遠弗屆地傳送給眾多的使用者。但是,目前的技術,並未考慮到資料庫間模式與查詢語言的差異性,使得他們之間沒有辦法達到完全的資源共享。本計畫設計一個詢問句處理器,有效地擴充關聯式資料庫與物件導向資料庫間的互通能力。 Recent advances in database technologies and communication technologies have led to the demand for interoperability of different information servers. In this project, we have developed techniques for producing interoperable queries with object and relational databases. A user poses a local query in a local query language, against a local object or relational schema. We transparently produce appropriate queries with respect to remote target object or relational databases, which contain data that are relevant to the user, so that data can be shared. A set of heterogeneous transformation algorithms define the appropriate transformations from the local queries to the remote queries.
