创建该池项目是为了实现LHC计算网格(LCG)应用领域的通用持久性框架。池的任务是以分布式和网格启用的方式将实验数据和元数据存储在多PB区域中。新框架的第一次生产使用预计将于2003年夏季开始。该项目采用混合方法，将C++对象流技术(如批量数据的根I/O)与事务安全的关系数据库(RDBMS)存储(如MySQL)相结合。Pool基于严格的组件方法-如LCG Perstency和蓝图rtag文档中所述-提供对分布式数据的导航访问，而不会暴露特定存储技术的细节。这份报告描述了将项目细分为工作包、主要池组件之间的高级别相互作用，并概述了当前的状况和计划。
The POOL project has been created to implement a common persistency framework for the LHC Computing Grid (LCG) application area. POOL is tasked to store experimen t data and meta data in the multi Petabyte area in a distributed and grid enabled way. First production use of new framework is expected for summer 2003. The project follows a hybrid approach combining C++ Object streaming technology such as ROOT I/O for the bulk data with a transactionally sa fe relational database (RDBMS) store such as MySQL. POOL is based a strict component approach - as laid down in the LCG persi stency and blue print RTAG documents - providing navigational access to distributed data without exposing details of t he particular storage technology. This contribution describes the project breakdown into work packages, the high level inter action between the main pool components and summarizes current status and plans.
