OCI 1Z0-1195-25 glossary of ingestion, cataloging, storage, pipelines, and governance terms.
On this page
Use this glossary to clean up high-confusion Oracle data-platform terms before you go back into mixed sets. On this exam, vocabulary mistakes usually hide a lifecycle-stage mistake.
High-value terms
Term
What it means here
Why it matters on the exam
Analytics
the consumption layer where prepared data supports reporting or decisions
questions often hinge on where consumption begins
Catalog
the metadata and discovery layer used to describe and find data assets
catalog is a governance surface, not a processing engine
CDC
tracked row-level inserts, updates, and deletes moved incrementally
this is a common tie-break against generic streaming
Data lineage
the record of where data came from, how it changed, and where it goes next
lineage is a common governance and trust signal
GoldenGate
Oracle technology used for replication and movement-style scenarios
often shows up when low-latency change propagation matters
Ingestion
bringing data into the platform from source systems or streams
strong answers classify ingestion before anything else
Metadata
descriptive information about data such as structure, owner, or usage
metadata is not the payload itself
Streaming
continuous event-oriented movement or processing
not every low-latency need is generic streaming
Transformation
cleaning, reshaping, validating, or enriching raw data
transformation is a separate responsibility from ingest
Warehouse-style analytics
structured query and BI consumption on prepared datasets
analytics tools are not movement or integration tools
Common confusion pairs
Pair
Clean separation
Catalog vs warehouse
the catalog describes and organizes data assets, the warehouse supports analytic use of prepared data
Ingestion vs transformation
ingestion brings data in, transformation changes its shape or meaning
Streaming vs CDC
streaming is ongoing event flow, CDC is tracked row-level change propagation
Metadata vs data payload
metadata describes the asset, the payload is the actual data
Movement tool vs analytics service
movement tools transport or replicate, analytics services help consume and analyze
Lineage vs retention
lineage shows history and flow, retention defines how long data is kept
