CRUD – an acronym standing for Create, Read, Update, and Delete. These four operations are the building blocks for storing data for systems and applications:
Create: The insertion of new data records into a storage system. This might be adding a document, user account, uploading a photo, or placing an order.
Read: The retrieval of existing data from a system as we, for example, search for a product, access a PDF, view a profile, or generate a report.
Update: Modifying existing data without creating a new record. Examples include editing profile information, changing a password, or updating inventory counts.
Delete: Removing unwanted data from the system. This might involve deleting old files, removing a social media post, canceling an order, or archiving old records. But archiving records means creating new records in the archival system.
These four operations provide a complete model for managing data throughout its lifecycle. Read more here.
