Abstract

Understanding the links between application programs and their database is useful in various contexts such as migrating information systems towards a new database platform, evolving the database schema, or assessing the overall system quality. However, data-intensive applications nowadays tend to access their underlying database in an increasingly dynamic way. The queries that they send to the database server are usually built at runtime, through String concatenation, or Object-Relational-Mapping (ORM) frameworks. This level of dynamicity significantly complicates the task of adapting programs to an evolving database schema. In this paper, we present DAHLIA 2.0, an interactive visualization tool that allows developers to analyze the database usage in order to support data-intensive software evolution and more precisely, program-database co-evolution.
DAHLIA 2.0:动态异构系统中数据库使用的可视化分析器
理解应用程序和它们的数据库之间的联系在各种上下文中都很有用,例如将信息系统迁移到新的数据库平台、发展数据库模式或评估整体系统质量。然而,如今的数据密集型应用程序倾向于以一种越来越动态的方式访问其底层数据库。它们发送给数据库服务器的查询通常是在运行时通过字符串连接或对象关系映射(ORM)框架构建的。这种级别的动态性大大增加了使程序适应不断变化的数据库模式的任务的复杂性。在本文中,我们提出了DAHLIA 2.0,这是一个交互式可视化工具,允许开发人员分析数据库使用情况,以支持数据密集型软件进化,更准确地说,是程序-数据库协同进化。
