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。
You may be wondering what happened to the OODB option that ASDI had preferred.
你也许正想知道对于ASDI首选的OODB的选择发生了什么。
Query processing is one of the important parts of object-oriented database (OODB).
在面向对象数据库(OODB)中,查询处理是其中重要的部分。
OODB, as the third generation database management system, is required new theories, methods and techniques.
作为第三代数据库的OODB,要求是新的理论方法和技术。
In most OODB, data can only be got access by programming language, the end users have no simple tool to execute query.
在大多数面向对象数据库中,数据只能通过程序设计语言来存取,终端用户没有一个简单的工具执行查询。
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。
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。
It changes the user query models into the identity query models in the database, and has accomplished the browsing of OODB.
通过标识映射把用户的查询转换为库中基于标识的查询,实现了OODB的浏览。
In this paper, a new query method which is based on generalization hierarchy in Object Oriented Database (OODB) is proposed.
针对面向对象的数据库(OODB)的概括继承结构提出一种新的查询途径,它建立在一种对象表示的基础上。
If we chose an OODB solution, we'd be a bit out of our depth, so it would force training and uncertainty into the engineering team's schedule.
假如我们选择OODB方案,我们必须扩展我们的深度,因此这会产生强迫的培训和对工程团队的时间进度产生不确定性。
The data store would require more thought, however, because the IT manager was pushing very hard for an object-oriented database (OODB) solution.
数据的存储应该被更多的考虑,然而,因为IT经理极力的推崇面向对象的数据库(OODB)方案。
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.
本文构造了一种OODB模式,并建立相应的视图及查询模型,确定它们之间的子包含关系,以达到查询优化的目的。
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。
On this basis, it raises a query optimization model for OQL by introducing some query theories of RDB into the query process of OODB, and gives its implement strategy.
在此基础上,将RDB的一些查询理论应用于OODB的查询中,提出了一种OQL的查询优化模型,并给出其实现策略。
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.
文章在研究与分析异构数据对应规则和异构数据转换规则的基础上,提出了建立在XML和面向对象数据库逻辑数据模型之上的异构数据交换规则。
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.
文章基于从面向对象数据库(OODB)到关系数据库(rdb)的模式转换,提出了一种从面向对象数据库查询到关系数据库查询的转换算法。
