Database systems are valued today on account of their ability to manage complex information and efficiently process queries on large data sets. However, they are difficult to use, requiring careful design of database structure, and precise specification of queries to match this structure. In consequence, there is a large barrier to adoption. This project seeks to remove these burdens from the user through the notion of organic, rather than engineered, creation of both database and queries.This project is developing databases that can be used even before the complete structure is specified. In the beginning, before much information is added, there may even be no structure at all. Over time, the user will be able to grow and evolve the structure organically as data is added and needs change. This project is also developing querying techniques for databases that reduce the burden on the user to specify a query exactly, and to know both the structure of the database being queried and the desired structure of the query result. This project, in contrast, will allow users to state an information need incrementally. Rather than structuring the result at the time of query specification, the user will be able to manipulate and structure the result set. These benefits are accomplished through the use of a presentation data model, which is implemented in the database system as a full-fledged layer above the logical and physical data model layers. Biomedical database applications are employed to test and refine the developed system. The research results are expected to greatly improve the way databases are used by both technical and non-technical users and to influence a generation of research in data management.

由于其管理复杂信息并有效地处理大型数据集的查询的能力，今天对数据库系统进行了重视。但是，它们很难使用，需要仔细设计数据库结构，以及查询的精确规范以匹配此结构。因此，采用了很大的障碍。该项目旨在通过有机的概念而不是工程性的数据库和查询来从用户那里偿还这些负担。此项目正在开发数据库，​​这些数据库甚至在指定完整的结构之前就可以使用。 一开始，在添加大量信息之前，甚至可能根本没有结构。 随着时间的流逝，用户将能够在添加数据并需要更改时有机地生长和发展结构。该项目还为数据库开发了查询技术，以减轻用户的负担以准确指定查询，并知道要查询的数据库的结构以及查询结果的所需结构。 相比之下，该项目将允许用户逐步陈述信息需求。 用户将能够操纵和构建结果集，而不是在查询规范时构造结果。这些好处是通过使用演示数据模型来实现的，该模型在数据库系统中作为逻辑和物理数据模型层上方的成熟层实现。 使用生物医学数据库应用程序来测试和完善开发系统。 预计研究结果将大大改善技术和非技术用户使用数据库的方式，并影响数据管理方面的一系列研究。 有关该项目的其他信息，请访问http://www.eecs.umich.edu/db/usable/。
