CRM Database:
What It Is and How It Works

A CRM database stores and organizes customer information inside a customer relationship management system. It brings together contact details, communication history, purchases, service requests, and preferences, as explained in Salesforce’s CRM database guide.

In HubSpot’s CRM model, an object defines a record type, a record represents an individual entity, properties hold its information, and associations connect it to other records. These terms describe the database’s structure.

What does a CRM database store?#

The following record types appear in the cited products. Their names and available fields should be checked in the documentation for the CRM being used.

How contacts, companies, and deals stay linked#

In Microsoft’s Dataverse model, relationships connect records through two types of association:

• One-to-many: multiple related records connect to one parent record.
• Many-to-many: records on both sides can have multiple connections to records on the other side.

These definitions explain the number of links a model permits. Dataverse also documents relationship behavior for assignment and deletion. Inspect those settings alongside the links themselves before changing related records.

Salesforce’s opportunity contact roles record deal participation by identifying the contact, their role in that opportunity, and whether they are designated as primary. Store deal participation against the relevant opportunity and keep the person’s general contact details on the contact record.

Salesforce’s administrator-enabled Contacts to Multiple Accounts feature connects one contact to several accounts without duplicate contact records, distinguishing the direct account relationship from additional indirect relationships.

For a database review, inspect company membership and deal participation separately. Confirm that the database preserves both the relevant contact and the meaning of each relationship. The Salesforce features above provide documented ways to represent those links.

Record IDs and ownership#

HubSpot’s Record IDs are unique within each object, so a contact and a company can share the same numerical identifier. Retain both the identifier and the record type when matching records across objects.

Ownership is a separate attribute. Microsoft’s Dynamics 365 Sales assignment documentation covers record owners, reassignment to sellers or teams, and status and error details for records needing attention.

For setup, define who maintains contacts, updates opportunities, and reviews assignment failures. Record identifiers establish which entry is being handled; ownership establishes who is responsible for it. Both belong in the import and maintenance checks.

How to populate a CRM database#

HubSpot’s import tool can create, update, and associate records by mapping spreadsheet columns to CRM properties.

Use this sequence to prepare an import:

1. Map the record types and fields. In HubSpot’s multi-object column mapping, each column needs the correct target object and property. Document that mapping before uploading.
2. Prepare the file format and values. HubSpot’s file requirements accept CSV, XLSX, and XLS files with one sheet and a header row. Check the required formats for dates, numbers, and predefined field options before uploading.
3. Specify record identifiers. HubSpot’s import identifiers include Record ID, contact email, company domain, and eligible unique-value properties; a mapped Record ID takes precedence over other identifiers.
4. Import the relationships. HubSpot’s multi-object imports can associate records using one file or two files with a shared column. Review the relationship mapping alongside the fields.
5. Validate the result. Salesforce’s migration guidance recommends checking accuracy, completeness, and consistency after loading data. Compare the imported records with the source and inspect the links between contacts, companies, and deals.

Update behavior also matters. Under HubSpot’s blank-cell rules, an empty cell in an import does not erase an existing property value. Review how the importer handles missing values and overwrites before using it to update existing records.

Managing duplicates, access, and exports#

Duplicate detection and duplicate handling are separate operations. In Salesforce, matching rules identify potential duplicates and duplicate rules determine the response, including warnings or blocking record creation. The documentation describes candidate matches rather than treating every match as a confirmed duplicate.

Use those candidates as a review queue. Before merging records, compare their identifying information, field values, and linked history. Keep identifying the entry to update separate from deciding whether two entries represent the same customer.

Access controls determine who can work with the stored information. HubSpot’s permissions documentation describes permissions for viewing, creating, editing, and deleting records. Define access according to the work each user needs to perform and check it with the relevant user accounts.

Check export coverage before using exported data for a migration or recovery process. HubSpot’s record export documentation covers current property values and configurable associations; contact activities use separate export methods, activity reports, or an API. Verify that the export includes the identifiers and relationships needed to reconstruct the intended records.
