It describes the model/view split of the calendar - into a personal calendar server, or PCS, and the GUI clients - that appear inside the Evolution shell. - </para> - - <!-- Model/View Separation --> - - <sect1 id="calendar-model-view"> - <title>Model/View Separation</title> - - <para> - Like other base components in Evolution, the calendar - separates the data model from the views or clients. This is - done so that multiple clients can access the same calendar - data in an orderly fashion and without clashes. For example, - the user may be running a graphical calendar client. If he - then wants to synchronize his calendar with a handheld device, - then the corresponding synchronization program (e.g. a conduit - for the <application>gnome-pilot</application> package) will - also need to access the calendar storage. It is important - that both the GUI client and the synchronization program keep - a consistent view of the calendar at all times, otherwise one - of them will be left in an inconsistent state if the - calendar's data changes unexpectedly. - </para> - - <para> - Evolution puts the calendar storage in a daemon called the - Wombat and completely separates it from clients who wants to - access calendar data. This part of the Wombat is called the - personal calendar server, or &PCS;. Clients must contact the - &PCS; and ask it to open an existing calendar or create a new - one. When a calendar component object (e.g. an appointment or - to-do item) changes in the &PCS; it will notify all the - clients that are using the component's parent calendar. - </para> - </sect1> - - <!-- Personal Calendar Server --> - - <sect1> - <title>Personal Calendar Server</title> - - <para> - The personal calendar server, or &PCS;, provides centralized - management and storage of a user's personal calendar. - Multiple clients can connect to the &PCS; simultaneously to - query and modify the user's calendar in a synchronized - fashion. The main features of the &PCS; are as follows: - </para> - - <formalpara> - <title>Storage</title> - - <para> - The &PCS; is responsible for loading and saving calendars. - Centralizing the loading and saving functionality allows - multiple clients to use the same calendar at the same time - without having to worry about each other. - </para> - </formalpara> - - <formalpara> - <title>Basic Queries</title> - - <para> - The &PCS; provides functions to do basic queries on a - calendar, for example, a client can ask the server for a - list of all the appointments in the calendar, or for all the - data for a specific appointment. - </para> - </formalpara> - - <formalpara> - <title>Recurrence and Alarm Queries</title> - - <para> - - </para> - </formalpara> - </sect1> - </chapter> - -<!-- -Local variables: -mode: sgml -sgml-parent-document: ("../evolution-devel-guide.sgml" "book" "part" "") -End: ---> |
