Performance based object storage selection

摘要

The selection of a database system upon which to build applications is a complex process where diverse and sometimes competing set of business and technology criteria must be satisfied. Making the right choice is ultimately a strategic business decision that has a profound effect on the near and long-term success of a software project. Implementing a robust persistent architecture is one of the most challenging tasks in designing a component-based application. Not only does persistence have a pervasive impact on the overall system structure, it also has a significant effect on development schedules and runtime performance of the resulting applications. In the article we focus on performance issues when storing objects in various types of databases. We explore the impact of inheritance, internal complexity, and inter object relations. We also focus on the impact of transaction size and number of concurrent users and identify advantages and disadvantages of various approaches to the implementation of persistence systems.
