01 / Time series
Turn a missing reading into a useful next step.
Request missing evidence, wait for late data, or recognize an interval when no reading was expected.

What are you trying
to make possible?
A question rarely stops at one data model.
Explore how several models contribute to a useful result.

From a native operation to a useful decision
Choose what the data should help you do.
Storing a structure is the beginning. Its operations determine which questions your application can answer.
02 / BioTwin / Lineage
When the evidence changes, know which answers to revisit.
An answer can keep the same number while its justification changes. Find the dependent work that needs review.
Trace changed evidence →03 / BioTwin / Order lattices
Keep the strongest alternatives visible.
A candidate may offer more benefit at more cost. Preserve the alternatives instead of hiding that choice inside one score.
Compare meaningful alternatives →Distinct implementation examples, with their scope explained at each destination. See the evidence and scope →

02 / From input to useful answer
The interesting part
is where models meet.
A familiar question often needs several kinds of data. Follow the work from its source to the answer.
Personal media / Illustrative workflow
“Find the photo from that evening by the lake.”
Similarity finds candidates. Time and place narrow the answer.

Native graph + typed time series + spatial composition
SurrealDB332.5
3.2.4 · tuned record-range layout
Same-host synthetic shipping fixture; same four logical CPUs per server; 20 timed requests each, including HTTP and decoded JSON. Exact ships and timestamps checked. Custom Rust composition versus SurrealQL. Preparation excluded; resident-memory paths without durable completion or authentication. This measures the combination, not an isolated graph, spatial or time-series operation.
Read the results, comparison and methods →Observed process memory: 213 MiB vs. 831 MiB
8DB used about 74% less resident memory at the recorded post-query checkpoint. Client and OS cache excluded; this is not a minimum device requirement. Energy and SSD wear were not measured.
Include memory, storage, energy and hardware writes
Record build-time and serving memory separately, original and derived stored bytes, measured joules per completed job, and physical writes including indexing, compaction and recovery. A smaller representation does not by itself prove lower energy or longer device life.
Match correctness, freshness, durability and protection across alternatives. Encryption, authorization, adapters, network setup and output delivery belong in the complete-job comparison wherever required. No universal zero-overhead claim follows from these results.
03 / The buying decision
A model list
is the beginning.
Multi-model databases such as SurrealDB already combine familiar representations. Compare what you can actually do with them, what information survives and what your team still has to assemble.
