Eclipse的EMF项目也正在遵循实体关系建模技术来捕获DSL。
Eclipse's EMF project is also following the entity-relationship modeling technique to capture DSLs.
还存在其他方法和形式,但是本文将集中于实体关系建模技术,因为此项技术与稍后将描述的技术更密切相关。
There are other approaches and forms, but this article focuses on the entity-relationship modeling technique because it is more closely related to the technologies described later.
对于其他数据源(比如非关系数据)或是其他的数据库访问技术(比如LINQ toSQL)来说,ADO.NET Data Services又提供了一种机制将这些数据源建模为实体和关系(比如通过EDMschema描述)并将其暴露为数据服务。
LINQ to SQL a mechanism is provided which enables any data source to be modeled as entities and associations ie. described using an EDM schema and exposed as a data service.
对于传统的建模技术,例如实体关系图或数据流程图,没有可用的特定测试技术会过时。
For traditional modeling techniques, such as entity relationship diagram or data flow diagram, no specific test techniques are available to date.
技术性数据质量维(technical data quality dimension)定义数据质量标准。数据质量标准常常可以在逻辑数据建模中的实体完整性和引用完整性关系规则中找到。
The technical data quality dimension defines the data quality criteria often found in both the entity integrity and referential integrity relational rules found in logical data modeling.
