## Content Management System (CMS)

- NAI Central has developed a Content Management System (CMS) for efficiently managing website content
- Key Features
- Allows website content to be added, updated and maintained using a secure web interface.
- Allows content owners to manage their own content which reduces bottlenecks and allows the web developer(s) to focus on other projects.
- Because website content is stored in a database, the look, feel, and organization of the website can be changed without having to reprogram content.

## Web Statistics Capability Overview 

**Who are our Visitors?**
- Using web log analysis, visitors can be categorized as USA public (.com, .net domains), USA government (.gov) USA educational (.edu) USA non-profit (.org) and international. Knowing the proportion of visitors from these categories provides data useful in determining if the target audience of the website is being reached.
- The list of visitors can be filtered to determine the number of visitors from a particular host or institution. The NAI has found this useful in determining the webpage usage of its members. The operating system, browser, and screen resolution of visitors is also collected.
