+# Delete & Cleanup Procedure
+
+The `sp_dr_cleanup` systematically cleans up data across related tables in the database, based on the data retention rules. This procedure is integral to maintaining the integrity and performance of the system by removing outdated records, and helps remain compliant with data protection and retention legislation.
+
+### Key Steps in the Cleanup Process
+
+1. **Initialization:**
+    - The procedure starts by checking system parameters to ensure that data deletion is not disabled. It sets some system parameters necessary for the run, including disabling foreign key checks and triggers for the remainder of the run.
+
+2. **Transaction Management:**
+    - A transaction is started to ensure that all changes are atomic and can be rolled back in case of any errors during the execution process. This is planned to be removed soon, to allow the DR process to run while the system remains online (albeit at a v.quiet time)
+
+3. **Temporary Tables Creation:**
+    - Temporary tables are created to manage the data that needs to be processed. These tables help isolate and track which records are to be deleted without affecting the live data during the cleanup process.
+
+4. **Deletion Criteria Setup:**
+    - Records eligible for deletion are identified based on the rules specified in the `data_retention` table and related `data_retention_rule`. This includes checking fields like `action_confirmation` and `deleted_date`.
+
+5. **Dependency Management:**
+    - The script handles dependencies carefully by ensuring that related records in dependent tables are also considered for deletion. This includes cascading effects where deleting a record in one table may affect records in multiple related tables.
+
+6. **Record Deletion:**
+    - Actual deletion of records occurs from various tables, based on the dependencies and relationships defined.
+
+7. **Verification and Cleanup:**
+    - After deletion, the script verifies the number of records deleted and ensures that the counts match the expected numbers. Temporary tables are used to compare pre and post-deletion record counts.
+
+8. **Transaction Completion:**
+    - If the `dry_run` parameter is set to `FALSE`, the changes are committed to the database. If `dry_run` is `TRUE`, all changes are rolled back, allowing the operation to be tested without affecting actual data.
+
+9. **Finalization:**
+    - The environment is reset by re-enabling foreign key checks and triggers. Temporary tables are dropped to clean up the session.
+
+### Error Handling
+
+- The procedure includes robust error handling mechanisms that catch SQL exceptions during execution. These exceptions trigger a rollback of the transaction, ensuring that the database state remains consistent and no partial updates are committed.
+- The above mechanism will not be possible when running without transactions, some consideration should be given to the impact of this change.
+
+### Usage
+
+- This procedure can be executed with parameters to specify the user ID performing the cleanup, the limit on the number of records to process, and whether the operation should be a dry run.

+# Data Retention System Overview
+
+The Data Retention system is designed to manage the lifecycle of records in compliance with regulatory and internal data management policies. This system uses a set of "populate rules" to determine when records are eligible for deletion, ensuring data is handled securely and efficiently.
+
+### Key Components
+
+#### Data Retention Rules
+
+- **Table:** `data_retention_rule`
+- **Description:** Stores the rules that define how data retention is handled for different types of entity. Each rule specifies the retention period, the maximum dataset size for consideration in a single run, and whether the rule is currently enabled.
+- **Key Fields:**
+    - `id`: Unique identifier for the rule.
+    - `description`: A brief description of what the rule does.
+    - `retention_period`: How long (in months) to keep the data after record closure.
+    - `max_data_set`: Limits the number of rows affected in a single operation.
+    - `is_enabled`: Indicates if the rule is active.
+    - `action_type`: Defines the type of action (e.g., automatic deletion, manual review).
+    - `populate_procedure`: The stored procedure associated with populating data for this rule.
+
+#### Data Retention Control Table
+
+- **Table:** `data_retention`
+- **Description:** Records information about data eligible for retention actions. It is populated by the stored procedures indexed in the  `data_retention_rule` table,
+- **Key Fields:**
+    - `entity_name`, `entity_pk`: Identify the database record to delete.
+    - `data_retention_rule_id`: Links to the applicable retention rule that populated the record.
+    - `action_confirmation`: Indicates whether the deletion action is confirmed by an admin user.
+    - `assigned_to`: User ID for accountability.
+    - `next_review_date`: When the record should next be reviewed.
+    - `actioned_date`: When the deletion took place for this record.
+
+### Process Flow
+
+1. **Rule Execution:**
+    - Stored procedures defined per rule in `populate_procedure` are executed regularly. These procedures evaluate records against their respective retention rules and populate the `data_retention` table with records eligible for deletion or review.
+
+2. **Admin UI Interaction:**
+    - An administrative UI in the `olcs-internal` web app allows users to manage retention rules and review records flagged for manual action.
+
+3. **Automated and Manual Deletion:**
+    - Records flagged for automatic deletion are processed in scheduled runs of the `sp_dr_cleanup` stored procedure, which handles the deletion of data and cleanup of any dependent records.
+    - Records requiring manual approval are not deleted in these runs until manually reviewed and confirmed through the admin UI, then deleted in subsequent cleanup runs.
+
+### Security and Compliance
+
+- The system is designed to ensure compliance with data protection regulations by allowing records to be deleted after per-entity retention periods have expired, and allows for review and manual intervention when necessary.
+
+### Conclusion
+
+The Data Retention system provides a framework for managing the lifecycle of data within the organisation. By automating data cleanup the system helps maintain data hygiene and regulatory compliance efficiently.
