With the development and progress of social informatization, OA office automation software has broken the traditional and complex office methods, enabling various industries to achieve efficient paperless office. As a result, OA has rapidly grown into the third largest management software after financial software and ERP software. With the continuous increase of enterprise information systems and the development of SOA integration technology, enterprises need an application framework that integrates various application systems, data resources and Internet resources into an information management platform, and realizes single sign-on to achieve a unified The user interface is provided to the user, and the Portal portal platform is widely used.
At present, the OA system also realizes single sign-on to other systems. Users can log in to the OA system to access or directly operate other business systems/reports/BI, etc. The functions of the OA system are gradually converging with those of the Portal platform, but to a certain extent, the two There is still a big difference between the systems, and the following is a detailed analysis of the difference between the two.
1 System Definition
1.1 OA office system
The full English name of OA system is Office Automation System, that is, office automation system. OA is the daily management and operation of an organization, and is the most frequently used application system by employees and managers. It combines corporate office and computer network technology. Since the first domestic office automation planning meeting was held in 1985, OA has been widely used in The depth and breadth of content and the application of IT technology have undergone new changes and developments, and have become an indispensable core application system for organizations. OA mainly implements a paperless office model.
1.2 Portal Portal Platform
Portal is a kind of platform web application, which is usually used to provide personalization, single sign-on, aggregate content of various information sources, and serve as the host of the presentation layer of the information system. Portal integrates the content from various information sources into a Web page through the built-in Mashup aggregation mechanism, and integrates various application system resources, data resources, and information resources in a unified and seamless manner. The application interface is simplified, and the user is organically linked through the processing and transmission of events and messages.
2 Function introduction
Different manufacturers' OA office systems and different manufacturers' Portal portal platforms have their own advantages and disadvantages in functions. Here, some common functions will be selected for explanation.
2.1 OA office system
1. Collaborative work
It mainly manages the daily work communication and collaboration process. Users can understand the progress of work tasks in real time in this module, and perform operations such as modification, approval, and rollback according to specific conditions. Satisfy the daily process processing of the enterprise, and quickly realize the accurate adjustment of the process.
2. knowledge management
In the form of knowledge center or knowledge community, enterprises can establish a knowledge catalog system in the knowledge center, and managers can publish internal knowledge documents, management experience, etc., and employees can view or share knowledge documents on this basis.
3. Administration
It mainly manages the attendance, leave, business trip, files, etc. of the internal personnel of the enterprise, including the employee's birthday reminder.
4. Resource management
It mainly manages the company's asset information, asset depreciation, vehicles, books, and office supplies. In addition to resource management, it also includes common meeting management functions, such as meeting room management, meeting records, and conference convening.
5. information Center
It is mainly used for enterprises to release some internal news in a unified manner, and can comment on the news. The published notices can be sent to employees through OA text messages or mobile phone text messages.
6. Graphical report
Managers can view the enterprise status in multiple dimensions in the form of graphs or reports, so that management can be based on evidence.
7. System Management
The system management of OA includes organization management, job management, position management, authority setting, role management, etc., that is, to define the organizational structure of the corporate headquarters and each department, and to set up and manage the positions of different roles in a unified manner. There are many built-in systems in the system. Permission definition, enterprises can define freely.
8. system integration
Mature OA systems usually also have system integration interfaces and extended development mechanisms. In the process of project implementation, the related systems are usually connected with the OA system itself through secondary development.
2.2 Portal Portal Platform
1. sign in
The single sign-on function of the Portal portal means that only one CAS authentication is required to access all other applications, which means that employees no longer need to log in to each system separately to complete work tasks. For example, after an employee enters a user name and password to log in to an enterprise-specific application center, he or she can freely access the human resources system, customer management system and other applications.
2. Access control
There is a strict permission control system in the Portal portal, which is mainly used to control the access rights of different levels of personnel. By authorizing roles, users, and groups, users, groups, and roles are managed in a unified manner.
3. Application integration
应用整合主要把企业各个应用系统的功能整合到统一的界面上展现，同时实现跨应用系统间的工作流程整合、应用间的数据共享，使应用间、用户间可以更好的协作。
4．数据分析
Portal门户平台可以收集不用应用系统间的业务数据，并把这些数据进行统一的分析整理，最终以各种文档、图形、图表的形式展现给管理层，使他们掌握公司业务运营情况。
5．多种门户
使用Portal门户平台可以搭建属于企业自己的应用门户（企业应用中心）、数据门户（企业各个应用数据统计分析看板）、信息门户（企业官方网站、企业外部交流论坛、企业官方博客、企业内部交流知识门户等）。
6．通讯管理
门户中的通信管理包括两部分，一种是基于门户实现的站内通讯，用户可以在此发送站内消息，收件人在登录应用中心的时候，右下角会弹出消息提醒，另一种是接入第三方邮件，在此可以接收来自外部邮件系统的邮件，并进行消息提醒。
7．个性化
Portal门户平台的个性化体现在两个方面，分别为页面的个性化和内容的个性化，页面的个性化是用户可以根据自身的爱好决定页面的布局和颜色；内容的个性化是用户可以根据自身的工作需要来决定界面上显示哪些内容。
8．定制开发
Portal门户产品具有的技术架构与规范的代码，为用户之后的Portlet组件、主题、功能的快速扩展提供了便利条件，可以根据客户需求灵活定制开发。
3 对比分析
因为这两款产品在不同的领域有不同的作用，笔者主要对两者功能相近的地方进行区别。
3.1 业务层面
OA办公系统主要是实现企业流程与人之间的协作，用于满足于企事业单位内部信息交流、共享、流转处理；内置多种提高工作效率的信息化设备和应用软件（HR人力管理、商务管理、资源管理、会议管理等），意在打造办公自动化，实现企业无纸化办公。
Portal门户平台主要实现系统间的整合，它可以将企业的所有应用系统集成在统一的界面上，这些系统包括：OA办公系统、财务系统、CRM客户管理系统、HR人力管理系统、进销存系统等，Portal更多的是一种前端界面层集成平台的概念，帮助企业系统的集成架构更标准化、统一化。
在流程处理方面，Portal门户平台不预置协同办公功能，但是Portal门户平台可以将其它应用系统（包括OA系统）的待办流程集成在一起。
3.2 功能层面
OA办公系统和Portal门户平台一样，内置多种门户功能，但是它们之间是存在差别的。
3.3 集成层面
OA系统的集成主要是实现其它系统跟OA系统的对接，是OA产品演进出来的高级特性；而Portal就是为界面层面集成而产生的，专门就是为了解决所有系统无缝对接，形成一个统一的门户平台，通常做为企业信息化的入口，OA系统也通常被集成于Portal门户平台中。
从技术层面来说OA办公系统是在UI页面基础上对用户需要的内容进行扩展，在集成方面稍弱一些，因为OA系统缺少标准接口，如果采用完全定制开发的集成模式，可能会给升级、系统性能带来一些风险和隐患。
Portal门户平台是专业应用于SOA集成领域的集成产品，无论是在解决方案中还是在案例上都更具有优势，而产品本身也遵循jsr168、286等标准规范，无论是企业现有的遗留系统，还是后续新增的信息化系统，都可以在构建的可平滑升级的架构平台上进行快速集成。
笔者一直接触Portal门户平台产品，近期发现OA产品功能有些地方与Portal门户平台产品相似，所以进行了一些研究对比，本文来自于个人见解，如果大家对这两款产品有什么看法或是更好的研究，可以加入技术交流群进行讨论299719834。
