Adding a store attribute to a field in Odoo 16 allows the field's value to be stored in the database rather than computed on-the-fly, improving performance by optimizing searches, filters, calculations and data retrieval from large datasets. Common uses of the store attribute include search/filter optimization, aggregated computations, faster report generation, and simplifying data exchange with external systems. The store attribute specifies whether a field is kept in the database or computed, with related and computed fields not stored by default but requiring store=True to be defined.

1. How to Add a Store
Attribute to a Field in
Odoo 16

2. In Odoo 16, adding a store attribute to a field allows you to
optimize the performance of your application by controlling how
data is stored and retrieved from the database. The store
attribute specifies whether the field's value should be stored in
the database or computed on-the-fly when accessed.

3. Here are some common use cases of store attribute:
• Search and filter optimization: Storing a field enables faster searching and filtering operations in Odoo, improving
query performance.
• Aggregated computations: Storing a field allows for efficient calculations and aggregations, saving processing time
when retrieving total values or performing calculations.
• Reports and analytics: Storing frequently used fields speeds up report generation and data analysis by eliminating
the need for on-the-fly computations.
• Data synchronization with external systems: Storing fields simplifies data exchange with external applications,
facilitating synchronization tasks.
• Performance optimization for large datasets: Storing certain fields enhances performance by minimizing on-the-
fly calculations, resulting in faster data retrieval and manipulation operations.

4. Let’s discuss how the store attribute works:
The image above shows the two fields we defined for the user and their login information.Because we designated it
as a related field, the login field is immediately filled when we select a user. In Odoo, related fields and computed
fields are not kept in the database; to do so, we must define store=True in a field.

5. Let’s take a look how we can store a field via XML,
The image above illustrates that we can define force_save="1" in a field to allow for the storage of a field in a
database using XML. This way we can store fields in database.
