If you are new to Salesforce, one of the very first concepts you will encounter is objects in Salesforce. Simply put, a Salesforce object is a database table that stores specific data related to your organization. Think of it like a spreadsheet tab — each object is a table with rows (called records) and columns (called fields).
For example, when a sales representative logs information about a new client, that data is stored inside the Account object. When a potential deal is being tracked, it lives inside the Opportunity object. Every meaningful piece of business data in Salesforce has a home — and that home is an object.
Simple Definition: A Salesforce object is a container that holds related business data. It is the equivalent of a database table, made up of fields (columns) and records (rows).
Objects in Salesforce are not just passive storage containers. They come packed with capabilities — you can build relationships between objects, create custom user interface tabs, define page layouts, set up validation rules, and configure powerful automation on top of them. This flexibility is precisely what makes Salesforce the world’s leading CRM platform.
Why Objects Are the Backbone of Salesforce
Understanding objects in Salesforce is essential because the entire platform is built on top of them. Every app, workflow, report, and automation in Salesforce ultimately traces back to data stored in objects. When you configure Salesforce for a business — whether for sales, customer service, marketing, or operations — you are largely deciding which objects to use, how to customize them, and how they should relate to each other.
From a Salesforce Admin’s perspective, objects are the very first building block of any implementation. Getting a solid grasp on objects sets the foundation for mastering everything else — automation, reporting, security models, and more.
Pro Tip: Salesforce objects and fields have API names that developers and integrations use to access data programmatically. Familiarity with object API names is essential for anyone pursuing a Salesforce Admin or Developer role.
Types of Objects in Salesforce
Salesforce organizes its objects into three primary categories. Each serves a different purpose and comes with its own set of rules and capabilities:
| Type | Created By | API Name Suffix | Purpose |
|---|---|---|---|
| Standard Objects | Salesforce (built-in) | No suffix (e.g., Account) | Common business processes |
| Custom Objects | Admin or Developer | __c (e.g., Property__c) | Unique business requirements |
| External Objects | Admin via Salesforce Connect | __x (e.g., OrderHistory__x) | Data stored outside Salesforce |
Beyond these three, Salesforce also offers Big Objects (for archiving massive data volumes) and Platform Events (for real-time event-driven integrations) — but Standard, Custom, and External objects are the core trio every Salesforce Admin must understand thoroughly.
Salesforce Standard Objects (with Examples
Standard objects are built directly into the Salesforce platform by Salesforce.com. They are available in every Salesforce org by default and are designed to support common sales, service, and marketing workflows. You cannot delete standard objects, but you can customize them by adding fields, creating page layouts, and configuring automation.
Most Widely Used Standard Objects
- Account
- Contact
- Lead
- Opportunity
- Case
- Campaign
- Product (PricebookEntry)
- Contract
- Task
- Event
- Report
- Dashboard
- User
Key Standard Object Descriptions
Account Represents a company or organization that you do business with. An Account stores the company name, industry, phone number, billing address, and much more. Every interaction — from support cases to deals — can be linked back to an Account.
Contact Represents an individual person associated with an Account. Contacts store details like name, title, email, and phone number. A single Account can have multiple Contacts associated with it.
Lead Represents a prospect — someone who has shown interest in your products or services but has not yet been qualified. Once a Lead is qualified, Salesforce allows you to convert it into an Account, Contact, and Opportunity in a single streamlined action.
Opportunity Tracks a potential sale or deal in progress. Opportunities have stages (such as Prospecting, Proposal, Negotiation, and Closed Won) that reflect where the deal stands in your sales pipeline. This is one of the most important objects for any sales team using Salesforce.
Case Used by support and service teams to track customer issues, complaints, or requests. Cases can be associated with Accounts and Contacts, and can be routed, escalated, and resolved using powerful automation tools.
Pro Tip: The relationship between Accounts, Contacts, Leads, and Opportunities is often called the core sales objects in Salesforce. Understanding how these four work together is critical for the Salesforce Admin Certification exam.
Salesforce Custom Objects
While standard objects cover common business needs, every organization has unique data requirements that do not fit the standard model. That is where custom objects in Salesforce come in. Custom objects are created by admins or developers to store data specific to their organization’s business processes.
For example, a real estate company might create a custom object called Property to track listings. A hospital might build a Patient Visit object. A school district might create a Student Enrollment object. The possibilities are limitless.
What You Can Build on a Custom Object
- Custom Fields — Add fields of any type: text, number, date, picklist, checkbox, formula, lookup, and more.
- Relationships — Relate the custom object to standard or other custom objects using Lookup or Master-Detail relationships.
- Page Layouts — Design the user interface for how records are displayed and edited.
- Custom Tabs — Create a navigation tab so users can easily access and manage records.
- Automation — Build Flows, Validation Rules, and Apex Triggers, just like on standard objects.
- Reports & Dashboards — Report on custom object data to gain actionable business insights.
Custom objects are identified in Salesforce by the __c suffix on their API name. For example, a custom object named “Invoice” will have the API name Invoice__c. This naming convention is something every Salesforce Admin must remember.
Â
Remember: All custom objects and custom fields in Salesforce end in
__cin their API name. This is how you distinguish them from standard objects and fields.
Salesforce External Objects
External objects in Salesforce allow users to interact with data that lives outside of the Salesforce database — without ever moving or duplicating it. Instead of importing external data, external objects create a real-time virtual link to that data using Salesforce Connect, which leverages the OData (Open Data Protocol) standard.
For example, if your company stores order history in a legacy ERP system, you could use an external object to surface that data directly inside Salesforce — so sales reps can view a customer’s full order history right on the Account page without switching applications.
External objects are identified by the __x suffix in their API names (for example, OrderHistory__x). They support many features of standard and custom objects — relationships, page layouts, and some reporting — but because the data is stored externally, certain automation types and triggers have limitations.
Pro Tip: External objects are an advanced topic typically covered in Salesforce Integration and Architecture certifications. However, understanding the concept and knowing when external objects are the right solution is valuable knowledge for any Salesforce Admin.
Standard vs. Custom Objects: Key Differences
| Feature | Standard Objects | Custom Objects |
|---|---|---|
| Created By | Salesforce (built-in) | Admin or Developer |
| API Name Suffix | No suffix (e.g., Account) | __c suffix (e.g., Property__c) |
| Can Be Deleted? | No | Yes |
| Customizable Fields | Yes (add custom fields) | Yes (fully customizable) |
| Tabs & UI | Included by default | Must be created manually |
| Automation Support | Full support | Full support |
| Reports & Dashboards | Supported | Supported |
| Use Case | Common business processes | Unique business requirements |
Object Relationships in Salesforce
One of the most powerful features of objects in Salesforce is the ability to create relationships between them. Just like in a relational database, these relationships let records in one object link to records in another, enabling you to model complex real-world business processes.
Lookup Relationship
A Lookup relationship creates a loose link between two objects. The child record can exist independently of the parent. For example, a Contact can be related to an Account via a Lookup, but a Contact can also exist without being tied to any Account.
Master-Detail Relationship
A Master-Detail relationship is a tighter, more controlled link. The child record (the “detail”) is bound to the parent record (the “master”). If the master record is deleted, all related detail records are automatically deleted as well. This relationship also enables rollup summary fields on the parent object — a powerful feature for aggregating data.
Many-to-Many Relationship (Junction Object)
When two objects need to relate to each other in a many-to-many fashion, Salesforce uses a junction object — a custom object with two Master-Detail relationships, one pointing to each of the two objects being connected.
Exam Note: The difference between Lookup and Master-Detail relationships is a frequently tested topic on the Salesforce Admin Certification exam. Be sure you understand cascade delete behavior in Master-Detail and the independence of Lookup relationships.
Fields on Salesforce Objects
Every object in Salesforce is made up of fields, which are the individual columns that store data within each record. Fields are the attributes of an object. For example, the Contact object has fields for First Name, Last Name, Email, Phone, and Title, among many others.
Common Salesforce Field Types
| Field Type | Description |
|---|---|
| Text | Stores alphanumeric characters |
| Number / Currency | Stores numeric or monetary values |
| Date / Date-Time | Stores date or timestamp values |
| Picklist | A dropdown list of predefined values |
| Checkbox | A true/false toggle |
| Formula | A calculated field based on other field values |
| Lookup | Creates a relationship to another object |
| Master-Detail | Creates a tight parent-child relationship |
| Auto Number | Automatically generates a sequential number |
Fields can be standard (provided by Salesforce) or custom (created by admins). Like custom objects, custom fields carry the __c suffix in their API names. Creating and configuring fields is one of the most frequent day-to-day tasks for a Salesforce Admin.
Frequently Asked Questions
What is the difference between an object and a record in Salesforce?
An object is the structure or template (like a spreadsheet tab), while a record is an individual entry within that object (like a row in the spreadsheet). For example, “Account” is the object, and “Acme Corporation” is a specific record within the Account object.
How many custom objects can you create in Salesforce?
The number of custom objects depends on your Salesforce edition. Salesforce Professional Edition allows up to 50 custom objects, Enterprise Edition allows up to 200, and Unlimited Edition allows up to 2,000. Always check the latest Salesforce documentation for current limits.
Can you delete standard objects in Salesforce?
No. Standard objects are permanently built into the Salesforce platform and cannot be deleted. However, you can hide them from users by removing their tabs from App configurations and restricting access through profiles and permission sets.
Are objects in Salesforce the same as tables in a database?
Conceptually, yes. Salesforce objects function very similarly to relational database tables — each has fields (columns) and records (rows), and you can create relationships between objects. The key difference is that Salesforce abstracts away the underlying database complexity through point-and-click configuration tools.
What is the __c suffix in Salesforce?
The __c suffix stands for “custom” and is automatically appended to the API names of all custom objects and custom fields. For example, a custom object named “Project” will have the API name Project__c. This convention helps distinguish custom components from standard ones throughout the platform.
Â
Do I need to know about objects for the Salesforce Admin exam?
Absolutely. Objects in Salesforce are a foundational topic in the Salesforce Administrator Certification exam. You need to understand object types, relationships (Lookup vs. Master-Detail), field types, and data organization. A strong grasp of this topic is non-negotiable for passing the exam.
Conclusion
Objects in Salesforce are the fundamental building blocks of the entire platform. Whether you are a business analyst evaluating Salesforce, a new admin configuring your first org, or an experienced developer building custom apps understanding Salesforce objects is always step one.
To recap what we covered:
- Standard objects come pre-built with Salesforce and cover common business needs like accounts, contacts, and opportunities.
- Custom objects let you model data unique to your organization and are fully configurable with the
__csuffix. - External objects bridge Salesforce with data stored in outside systems via Salesforce Connect.
- All objects are made up of fields and can be connected through powerful relationship types Lookup, Master-Detail, and Junction objects.
