In literatures, a hierarchical database structure is proposed in which the location information of mobile clients within a cell is managed by the location database responsible for the cell.

Business applications are enabled by performant data management systems: CICS, an application and transaction server, and IMS, a transaction and hierarchical database management system.

业务应用程序受到两个性能数据管理系统的支持：CICS，应用程序和事务服务器；IMS，事务和层级数据库管理系统。

A good algorithm to design such a hierarchical database consists of two steps, first, to describe real world in E-R model and then, convert it to the model supported by the DBMS.

在设计层次型数据库时，一个较好的设计方法是分二步走：首先利用实体联系方法抽象出现实世界的实体联系模型，然后将实体联系模型变换到具体DBMS所支持的层次型模型。
