Data modeling is the process of designing the structure of data in a software application. In Salesforce, data modeling is an essential part of building custom applications on the platform. It involves creating objects, fields, and relationships between objects to define the structure of the data.
In this post, we will explore data modeling in Salesforce in detail and discuss some best practices to follow while designing a data model.
Identify the Business Requirements in Data Modeling
Before starting to design a data model, it is important to understand the business requirements and how data will be used in the application. This will help ensure that the data model is designed to meet the needs of the business. Some important questions to consider during this stage include:
- What data needs to be stored in the application?
- How will the data be used by the users?
- What are the data security requirements?
By answering these questions, you can identify the objects and fields that will be needed to store and manage data in the application.
Once the business requirements have been identified, the next step is to create objects. In Salesforce, objects represent entities or concepts in the business organization, such as customers, products, or orders.

Objects represent entities or concepts in the business domain. For example, customers, products, or orders can be represented as objects in Salesforce. An object is made up of a set of fields that represent the individual pieces of data associated with that object. Salesforce provides standard objects, such as Accounts, Contacts, Opportunities, and Cases, that are commonly used in business applications.
In addition to standard objects, Salesforce allows developers to create custom objects to store data that does not fit into standard objects. Custom objects can be created using the Object Manager in Salesforce. When creating custom objects, it is important to keep the data model simple and avoid creating too many custom objects, as this can make the data model complex and difficult to maintain.
To create a custom object in Salesforce, follow these steps:
- Click on the Setup icon in the top-right corner of the screen and select Object Manager.
- Click the Create button and select Custom Object.
- Enter a label and a plural label for the object, as well as an object name.
- Define the object’s properties, such as the record name format and the object’s visibility.
- Click Save to create the object.
Once the object has been created, you can add fields to it to store data.
Fields represent individual pieces of data that are associated with an object, such as the name, address, or email of a customer. Salesforce provides a set of standard fields that can be used to store common types of data, such as text, numbers, and dates. In addition to standard fields, developers can create custom fields to store additional data that is specific to their business requirements.
When creating custom fields, it is important to choose the appropriate data type for the field. For example, if the field will store a date, the Date data type should be used. Using the appropriate data type ensures that data is stored efficiently and can be easily queried and analyzed.
To add fields to an object in Salesforce, follow these steps:
- Navigate to the object in the Object Manager.
- Click the Fields & Relationships tab and click the New button.
- Select the type of field you want to create and enter a label for the field.
- Define the field’s properties, such as the field length and the picklist values.
- Click Save to create the field.
Relationships between objects are an important aspect of data modeling in Salesforce. They define how data is related between objects and how it can be accessed in the application. There are three types of relationships in Salesforce: one-to-one, one-to-many, and many-to-many.
Objects can be related to each other in various ways, such as one-to-one, one-to-many, or many-to-many relationships. Defining relationships between objects is an important part of data modeling in Salesforce, as it determines how data will be organized and accessed in the application.
There are two types of relationships in Salesforce: standard relationships and custom relationships. Standard relationships are predefined relationships between standard objects, such as the relationship between Accounts and Contacts. Custom relationships are relationships between custom objects or between a custom object and a standard object.
One-to-One Relationship Data Modeling:
A one-to-one relationship is a relationship where each record in one object is associated with one record in another object. For example, an Employee object might be related to a Manager object in a one-to-one relationship. In this case, each employee is associated with one manager.

To create a one-to-one relationship between two objects in Salesforce, a Lookup relationship can be created. A Lookup relationship allows one object to reference another object. For example, an Employee object can have a Lookup field that references a Manager object.
A one-to-many relationship is a relationship where each record in one object is associated with many records in another object. For example, an Account object might be related to many Contact objects in a one-to-many relationship. In this case, each account is associated with many contacts.
To create a one-to-many relationship between two objects in Salesforce, a Master-Detail relationship can be created. A Master-Detail relationship allows one object to be the master, or parent, of another object. For example, the Account object can be the master of the Contact object, with each contact record being related to one account record.
A many-to-many relationship is a relationship where each record in one object is associated with many records in another object, and vice versa. For example, a Campaign object might be related to many Contact objects, and each Contact object might be related to many Campaign objects. In this case
To create a relationship between two objects in Salesforce, follow these steps:
- Navigate to the object in the Object Manager that will be the child in the relationship.
- Click the Fields & Relationships tab and click the New button.
- Select the type of relationship you want to create and select the parent object.
- Define the relationship’s properties, such as the relationship name and the relationship fields.
- Click Save to create the relationship.
Once the relationship has been created, you can use it to access data from the parent object in the child object’s records.
Use Standard Objects and Fields When Possible
Salesforce provides a set of standard objects and fields that can be used to store common types of data, such as accounts, contacts, and opportunities. Whenever possible, it is best to use these standard objects and fields, as they are already optimized for performance and provide built-in functionality.
Using standard objects and fields also makes it easier to integrate with other Salesforce applications and third-party applications that use the same data model.
