| ACID Compliance | May or may not be ACID compliant. | Must be ACID compliant to ensure data consistency and reliability. |
| Scalability | May have limitations on scalability. | Scalable to support large and complex data sets. |
| Normalization | May or may not follow normalization rules. | Must follow normalization rules to avoid data redundancy and improve data integrity. |
| Transactions | May not support transactions or may have limited support for transactions. | Supports transactions to ensure data consistency and reliability. |
