Here, we construct an OODB schema that recognizes subset relationships between a query and a view, through which we can gain the object of query optimization.
This paper first introduces the design idea of OODB language OSQL.
本文首先介绍了数据库语言osql的设计思想。
They preferred an OODB (object-oriented database) for the data store.
他们首选OODB(面向对象的数据库)作为数据的存储。
When ASDI「s technical lead started pushing for an OODB solution, we were concerned by this introduction of a new technology.
当asdi的技术领导开始力推一个面向对象的数据库方案时,我们对这个新技术的引入表示担心。
Schema evolution is a key problem in object-oriented systems because the dynamic nature of typical OODB applications calls for frequent changes in the schema.
模式演化是OO系统中一个很关键的问题。由于OODB的应用具有动态特征,因而模式要经常改动。
In this paper, based on a schema translation from Object-Oriented Database (OODB) to Relational Database (RDB), it proposes an algorithm for translating OODB query to RDB query.
With the analysis of correspondence and translation for heterogeneous data, this paper presents heterogeneous data exchanging rules based on XML and OODB logic data model.
Since ASDI had agreed that an OODB wouldn」t be prudent for this project, we no longer had that technical risk to manage.
因为ASDI同意对于这个项目OODB 是不合适的,我们因此不再有技术上的风险要管理。
Can effectively solve a lot of problems in the area of OODB with the realizing technology of relation database system (RDBS), which likely make OODB, from either the apparent meaning or the...
