Metadata
The invisible architecture that turns raw data into meaningful knowledge
30 hours ago
0
Why is metadata considered infinite even when the data asset it describes is finite?
Because metadata can continuously expand with new descriptive elements and context.
Because the data asset itself keeps growing over time.
Because metadata is just a fixed set of labels attached to data.

Backup Systems
Backup systems quietly prevent countless data disasters every day worldwide
5 days ago
0
What is a key trade-off when choosing between full and incremental backup strategies?
Incremental backups always provide faster restoration than full backups.
Full backups take longer and use more storage but simplify restoration, while incremental backups are faster and smaller but complicate recovery.
Full backups are unnecessary if incremental backups are performed regularly.

Personal Backup
Personal backups are the silent guardians against digital catastrophes few anticipate
5 days ago
0
What is a critical trade-off when choosing between local and cloud personal backups?
Local backups offer faster recovery but are vulnerable to physical damage, while cloud backups provide offsite safety but depend on internet access.
Cloud backups are always faster and more secure than local backups.
Backing up files on the same device as the originals is sufficient protection against data loss.

Data Source
Data sources shape the battle between static storage and real-time information flow
8 Feb 2026
0
What is a key trade-off when choosing between a database and a data stream as a data source?
Databases and data streams are identical in how they handle data and system requirements.
Databases offer structured, stable storage but lack real-time data flow, while data streams provide immediate updates but require complex processing.
Data streams are always superior to databases because they store more data permanently.
