-A Proto defines some type of [[protogrid:card|Card]] in your Application. A proto can be seen as a template for Cards. Every proto has a name and a plural name for the [[protogrid:overview_proto|overview Proto]]. The Proto defines the [[protogrid:field|fields]] and [[protogrid:widget|widgets]] on the card. Also one can specify [[protogrid:access_rights|access rights]] for all Cards based on this Proto and which [[protogrid:script_library|Server Script Library]] belongs to this Proto.+A Proto defines some type of [[protogrid:card|Card]] in your Application.

-== Find the Proto Key == +===== Comparison with relational databases ===== 
-To get the Protokey of a Card, first open the relative Proto by clicking onto "This Card --> Open Proto" in the bottom left corner:+In relational databases, the data model is represented by the table schema. A table for "books" may define the attributes "ID", "name", "author", such that each data entry has to define a value for each of these attributes. In Protogrid, a Proto takes the role of the table in such a way that it defines the data schema for all cards which are based on this Proto.

 +==== Overview Proto ====
 +An Overview Proto is automatically created on the creation of a new Proto. The Overview Proto only contains a [[protogrid:tableview|Tableview]], containing all the Cards of the created Proto.
 +
 +==== Data Proto ====
 +Every Proto containing more than a TableView is called a Data Proto, since it also contains some information stored in the Card and not only an overview of all the Cards.
