SDMN: A Powerful Tool for Salesforce Developers, Architects, and Administrators


SDMN: A Powerful Tool for Salesforce Developers, Architects, and Administrators

Salesforce Data Model Notation (SDMN) is a graphical notation used to represent the data model of a Salesforce organization. It is a standard notation that is used by Salesforce developers, architects, and administrators.


SDMN is based on the Entity Relationship Diagram (ERD) notation, which is a well-established notation for representing data models. SDMN extends ERD notation to include additional features that are specific to Salesforce, such as:

  • The ability to represent custom objects and fields

  • The ability to represent relationships between objects

  • The ability to represent cardinality and optionality of relationships

  • The ability to represent lookup relationships

  • The ability to represent master-detail relationships


SDMN is a valuable tool for understanding and communicating the data model of a Salesforce organization. It can be used to:

  • Document the data model of a Salesforce organization

  • Communicate the data model to stakeholders

  • Identify potential problems with the data model

  • Plan changes to the data model

  • Test the data model


Elements of SDMN

The basic elements of SDMN are:

  • Objects: Objects are the basic units of data in Salesforce. They represent entities such as customers, accounts, and opportunities. Objects are represented by boxes in SDMN diagrams.

  • Fields: Fields are the data elements that are stored in objects. They can be of different data types, such as text, number, and date. Fields are represented by ovals in SDMN diagrams.

  • Relationships: Relationships are the connections between objects. They represent the way that data in one object is related to data in another object. Relationships are represented by lines in SDMN diagrams.

  • Cardinality: Cardinality refers to the number of records in one object that can be related to a record in another object. There are three types of cardinality:

  • One-to-one: A record in one object can be related to only one record in another object.

  • One-to-many: A record in one object can be related to multiple records in another object.

  • Many-to-many: A record in one object can be related to multiple records in another object, and a record in the other object can be related to multiple records in the first object.

  • Optionality: Optionality refers to whether or not a relationship is required. A required relationship means that a record in one object must be related to a record in another object. An optional relationship means that a record in one object can be related to a record in another object, but it does not have to be.

  • Lookup relationships: Lookup relationships are a type of relationship where a record in one object can point to a record in another object. Lookup relationships are represented by a line with an arrow in SDMN diagrams. The arrow points from the object that is doing the pointing to the object that is being pointed to.

  • Master-detail relationships: Master-detail relationships are a type of relationship where a record in one object (the master object) can have multiple child records in another object (the detail object). Master-detail relationships are represented by a line with a diamond in SDMN diagrams. The diamond is located on the side of the object that is the master object.


Diagramming Tools

  • Salesforce Architect: This is a free tool that is provided by Salesforce. It can be used to create and edit SDMN diagrams, as well as other types of diagrams. Salesforce Architect is a good choice for users who are familiar with Salesforce and who want to use a tool that is specifically designed for Salesforce data models.

  • Lucidchart: This is a paid tool that can be used to create and edit a variety of diagrams, including SDMN diagrams. Lucidchart is a good choice for users who need a more powerful and versatile diagramming tool. Lucidchart also offers a number of features that are not available in Salesforce Architect, such as the ability to collaborate on diagrams and the ability to export diagrams to a variety of formats.

  • Gliffy: This is a free tool that can be used to create and edit a variety of diagrams, including SDMN diagrams. Gliffy is a good choice for users who are looking for a free and easy-to-use diagramming tool. Gliffy does not offer as many features as Lucidchart, but it is a good option for users who only need to create basic SDMN diagrams.


Here are some other popular diagramming tools that can be used to create SDMN diagrams:

  • Dia: This is a free and open-source diagramming tool that can be used to create a variety of diagrams, including SDMN diagrams. Dia is a good choice for users who are looking for a powerful and customizable diagramming tool.
