Software Architecture of the OLA Observatory Information System for Lake Environmental Research

OLA Information system (©SOERE OLA-IS, AnaEE-France, INRA Thonon-les-Bains, developed by Eco-Informatics ORE INRA Team) has been developed to meet data management needs of lake environmental research observatories in order to make data available for scientific communities. Software architecture of this IS is structured around (i) a shared central component dedicated to generic functions and (ii) modular components specific to lake thematics. The creation of the IS is done by inheriting the core component and using the appropriate modular components. SI is developed with the Java language (version 8). The components are Java projects that follow the structuring of a "multi-module" Maven project. The web interfaces are developed by using the framework JSF with Primefaces user interface component library. Spring and Hibernate frameworks complete the development tools. PostgreSQL is the relational database management system used. (2019-01-18). This information system makes it possible to store and make available physico-chemical data, biodiversity data (phytoplankton, zooplankton, fishes), data from multiparameter probes, chlorophyll, primary production, etc.

OLA信息系统（OLA Information System）由法国国家农业研究院（INRA）生态信息学ORE团队开发，版权归属于SOERE OLA-IS、AnaEE-France以及INRA蒂永河畔布洛涅分部，其开发旨在满足湖泊环境研究观测站的数据管理需求，为科研社群提供可共享的观测数据。
该信息系统的软件架构围绕两大核心模块构建：(i) 承载通用功能的共享中央组件，(ii) 适配湖泊研究主题的专属模块化组件。该系统通过继承核心组件并调用适配的模块化组件完成搭建。
该系统采用Java语言（版本8）开发，所有组件均为遵循“多模块”Maven项目规范的Java工程。Web界面基于JSF框架结合Primefaces用户界面组件库开发，配套使用Spring与Hibernate框架作为开发工具。系统采用PostgreSQL作为关系型数据库管理系统。（2019年1月18日）
该信息系统可存储并对外共享物理化学数据、生物多样性数据（包括浮游植物、浮游动物、鱼类数据）、多参数探针监测数据、叶绿素数据以及初级生产力数据等。
