Argos comprises several major components; some components run on your servers, others on your desktops. Understanding these components will help you plan your Argos installation.
The Argos database houses all the data Argos collects, all the lists Argos maintains (billing codes, devices, users, etc.), and all your settings and policies. You should maintain one Argos database for your company, even if you have multiple locations.
The Argos database runs on Microsoft SQL Server. If you already have SQL Server installed and licensed and want to use it, the Argos database installer will present you with the opportunity to do so. If you don't have SQL Server or would prefer to use the dedicated Argos SQL instance, Argos includes Microsoft SQL Server 2008 Express.
Argos installs two server components:
Argos Manager is where you configure your Argos system and work with the data that Argos collects. From Argos Manager you can run reports, export data, change policies, and more. Argos Manager is typically installed on only a handful of computers for accounting, finance, and I.T. staff. Read more about working with Argos Manager here .
The Argos Desktop Client (DtC) prompts users to allocate their activity to billing codes. The DtC should be installed on each workstation where you wish to prompt users. Users whom you wish to track silently do not need the DtC.
