摘要

软件即服务(SaaS)业务中的服务提供商向多个租户提供相同或类似的服务。表示、业务逻辑和持久层由所有租户共享。然而,在许多情况下,租户非常需要定制他们的应用程序。在本文中,我们研究了实体-属性-值(EAV)数据库在多租户应用程序中的使用。在EAV设计中,属性不记录为表中的列,而是记录为行。由于数据库是为更改表中的行数而不是列数而设计的,因此可以提高自定义过程的性能。

The Entity-Attribute-Value Data Model in a Multi-tenant Shared Data Environment
Service providers in the Software as a Service (SaaS) Business offer the same or similar services to multiple tenants. Presentation, business logic and persistence layer are shared by all tenants. However, in many cases tenants have a great need to customize their application. In this paper we investigate the use of Entity-Attribute-Value (EAV) databases for multi tenant applications. In the EAV design attributes are not recorded as columns in a table but in rows. Since databases are designed for changing the number of rows rather than columns in tables this improves the performance of the customization process.
