DLM focuses on managing the entire lifecycle of data, including its creation, storage, use, and eventual disposal, with a key emphasis on defining and enforcing data retention policies.

Data Archiving is not a typical phase in the DLM process. Instead, it is a specific storage strategy used to manage inactive data.

ILM focuses on managing the entire lifecycle of information, including its creation, storage, use, and eventual disposal, with a focus on managing the flow of information within an organization.

Information Archiving is not a typical phase in the ILM process. Instead, it is a specific storage strategy used to manage inactive information.

The primary difference between DLM and ILM is that DLM focuses on managing the lifecycle of data, while ILM focuses on managing the lifecycle of information. Data is a raw collection of facts, while information is data that has been processed and organized into a meaningful context.

Data Retention Policies are a key component of both DLM and ILM, as they define the rules for how long data and information should be retained before being destroyed.

Data classification is used in DLM and ILM to identify and categorize data based on its sensitivity and importance, which helps in determining the appropriate storage and retention policies, as well as the level of security required.

Tertiary Storage is not a common data storage strategy used in DLM and ILM. It refers to long-term, offline storage that is typically used for archival purposes.

Metadata plays a crucial role in DLM and ILM by providing information about the data, its lifecycle stages, and its characteristics, which helps in managing and tracking the data throughout its lifecycle.

Rapidly changing technology landscape is not a common challenge in implementing DLM and ILM. While technology advancements can impact data management practices, they are typically addressed through regular updates and enhancements to DLM and ILM strategies.

The primary goal of data migration in DLM and ILM is to move data from one storage system to another, often to improve data accessibility, performance, or to comply with regulatory requirements.

Increased data accessibility and usability is not a typical benefit of implementing DLM and ILM. While DLM and ILM can improve data management practices, they primarily focus on data governance, compliance, security, and cost reduction.

Data governance plays a crucial role in DLM and ILM by establishing policies and procedures for managing data, ensuring data quality and integrity, facilitating data sharing and collaboration, and protecting data from unauthorized access.

PCI DSS (Payment Card Industry Data Security Standard) is not a common industry standard or regulation directly related to DLM and ILM. It is primarily focused on protecting payment card data.

Data retention policies are used in DLM and ILM to define how long data should be retained before being destroyed, based on legal, regulatory, or business requirements.
