Naming Conventions for Custom Objects 

Your Salesforce chairman characterizes a related name field for every custom item during the arrangement. Custom items must include special names inside your association. 

In the API, the names of custom items incorporate a postfix of two underscores followed by a lowercase "c" . For instance, a custom article marked "Issue" in the Salesforce UI is Issue__c in that association's WSDL. 

Connections change the naming show. See Relationships Among Custom Objects for more data. 

For a custom article record to show up in the Salesforce UI, its name field must be populated. In the event that you utilize the API to make a custom article record that doesn't have a name, the record's ID is utilized as its name. 

Connections Among Custom Objects 

Custom items carry on and identify with different articles simply like standard items do, as portrayed in Relationships Among Objects. For instance, falling erases are upheld in custom items in a Master-Detail relationship. 

Custom articles can likewise have many-to-numerous associations with other custom items or standard items. A many-to-numerous relationship permits each record of one item to be connected to different records from another article and the other way around. For more data, see Relationships Among Objects. 

Custom articles require uncommon treatment with the goal that they can partake in Relationship Queries. For the relationship field name of a custom item, __r is affixed to the name to make the ID. Likewise, __c is affixed to the name to make the parent object pointer. For instance, if the relationship field name is MyRel, the name of the ID becomes MyRelId__r, the parent object pointer becomes MyRel__c, and the relationship name is MyRel__r. For more data, see Understanding Relationship Names, Custom Objects, and Custom Fields in the Salesforce SOQL and SOSL Reference Guide. 

This table sums up whether a standard item can be: 

• The ace in an ace detail relationship with a custom article. Ace detail connections include falling erases and sharing standards that the parent controls. 
• The query in a query relationship on a custom item. As such, regardless of whether a custom article can have a query to the standard item.
