Principles of site administration in SAPID. In a common way, at a top of a screen you can see main administrative panel, which contains links to system interfaces. Right below it secondary administrative panel is situated. It contains links to secondary services. Pay your attention to a right top corner of a screen. There's a status panel with “edit”, “view”, “logout” or “save”, “cancel” and “logout” buttons. A set of this buttons depend on current mode of a document. SAPID uses “direct editing” principle, so this mean that you edit all your documents directly by browsing a site. At any time you can press “view” button to view current document, then you may use “edit” button to edit its content. “Save” button save all changes made to document content. “Logout” button finishes administrative session.
