Historical records are preserved. Hard Delete in SQL: Definition: Hard delete involves the permanent removal of a record from the database. Implementation: Typically accomplished using the SQL DELETE statement. Advantages: Frees up storage space. Improves query performance. Deletion in Informatica PowerCenter: Soft Delete in Informatica PowerCenter: Usage: Implemented through the use of mapping logic. Example: Utilizing a filter transformation to exclude records marked for deletion. Advantages: Retains data integrity. Allows for auditing and tracking changes. Hard Delete in Informatica PowerCenter: Usage: Employing the DELETE command in SQL within a mapping. Example: Using a SQL transformation to execute the DELETE statement. Advantages: Efficient for large-scale data purges. Reduces storage overhead. Deletion in Informatica Cloud: Soft Delete in Informatica Cloud: Implementation: Similar to Informatica PowerCenter, achieved through mapping logic. Example: Applying filter transformations to exclude soft-deleted records during data integration. Advantages: Enables data governance. Supports compliance requirements.
