How can you maintain data integrity as a DBMS administrator?

As a DBMS admin, make sure data is correct. Set rules like primary keys, foreign keys, and unique values. Use checks, triggers for accuracy and regularly check and clean data

To maintain data integrity, defining rules and constraints is crucial. This involves specifying data types, formats, ranges, and relationships to ensure accuracy and consistency. Utilize primary keys for uniqueness, foreign keys for relational integrity, unique constraints to prevent duplicates, check constraints for value validation, and triggers for automated rule enforcement. Employ data dictionaries and docs for clear data insights. Regularly scheduled backups, stored securely, protect against data loss/corruption. It’s critical to test + verify these backups to ensure they can be effectively restored when needed. This comprehensive approach ensures data integrity and availability, safeguarding your organization’s informational assets.

Estabelecer e aplicar políticas de controle de acesso para garantir que apenas usuários autorizados tenham permiss?o para acessar, modificar ou excluir dados sensíveis, no caso do Oracle podemos utilizar do Oracle Virtual Private Database (VPD).

Data Validation Rules: Establish and enforce data validation rules to prevent entry of inaccurate or inconsistent data. Referential Integrity: Define and enforce foreign key constraints to maintain consistency between related tables. Transaction Management: Implement proper transaction management to ensure atomicity, consistency, isolation, and durability (ACID properties) during data operations. Regular Backups: Schedule and perform regular backups to safeguard against data loss or corruption, allowing for swift recovery. Access Controls: Enforce strict access controls and permissions to prevent unauthorized access, modification, or deletion of data. Data Quality Checks: Conduct regular data quality checks

Regularly back up the entire database with automated jobs, using a combination of full and incremental backups. Store copies in the cloud, test recovery procedures, and monitor backups for reliability.

Detalhe as diferentes estratégias de backup, como backup completo, incremental, diferencial, archivelog e a importancia de escolher a estratégia certa com base nos requisitos do sistema, hardware etc. Descreva procedimentos eficientes de recupera??o de dados após incidentes, sempre documente com riqueza de detalhes e evidencias afim de evitar o mesmos erros e falhas.

Introduza ferramentas e tecnologias específicas para monitoramento e auditoria, como logs de transa??es, triggers, e sistemas de gerenciamento de auditoria. Destaque casos práticos em que a monitoriza??o eficiente evitou ou identificou problemas.

Explique os métodos de valida??o de dados, incluindo restri??es de domínio, regras de verifica??o e procedimentos de limpeza. Demonstre como a limpeza de dados contribui para a precis?o e confiabilidade das informa??es.

Aborde a importancia da conscientiza??o sobre seguran?a de dados e as práticas recomendadas. Inclua exemplos de programas de treinamento bem-sucedidos e seu impacto na integridade dos dados.

Discuta a necessidade de revis?es regulares para se adaptar a mudan?as nos requisitos do sistema e regulamenta??es. Destaque casos em que a falta de atualiza??o de políticas levou a problemas de integridade.
