custom objects and fields what naming conventions

1. Custom Objects

Rules for Naming
Custom object names should be unique, beginning with an uppercase letter. Whole words should be used and use of acronyms and abbreviations should be limited. The object name should be singular (e.g. Review vs. Reviews, or OrderItem vs. Order Items) and should not include any underscores "_". The object label when at all possible should be similar to that of the object name since giving the label a different name than the object will make the object hard to find in some place within Salesforce.

Exceptions
Widely used and commonly understood acronyms and abbreviations can be used instead of the long form. For example HTTP or URL or ACMA. Added an underscore is acceptable if you are prefixing the object name to denote it is part of an application. For example: OrderApplication_Order and OrderApplication_OrderItem. Notice that OrderItem does not have any underscores.

2. Custom Fields

Rules for Naming
Custom object names should be unique, beginning with an uppercase letter. Whole words should be used and use of acronyms and abbreviations should be limited. Similar to custom object naming, custom fields should not contain any underscores "_". When creating custom fields always complete the “Description” field unless the field name would be completely obvious to someone not familiar to the application as to what is the purpose of the field.

Exceptions
Widely used and commonly understood acronyms and abbreviations can be used instead of the long form. For example HTTP or URL or ACMA.
