The Links page is used to create relationship between entities; links are translated into database links (foreign keys). For example you may create a Link from entity "Person" to entity "Address" and define how many different addresses a person can have.
|Link name||Name of the link (e.g. PersonAddress). The name must be unique.|
|Entity from||Name of the entity from which the link is defined (e.g. Person)|
|Entity to||Name of the entity to which the link is defined (e.g. Address)|
|Cardinality||Cardinality of this link (e.g. how many different addresses a person can have). If there is no limit, set the cardinality as 0.|
|Exclusive||Define if the link is exclusive (activate this option if an Address can be associated to 1 and only 1 person). Note: if the link is NOT exclusive, the cardinality must be set to 1.|
|Field name (optional)||Database field name used for the foreign key. If not provided, a default name is created by Opadeez.|
