Content Management System (CMS)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.

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.
