Database Query for Patient Records
Dominic Drake's estate sued Valley Regional Hospital after his death. The estate served a request for production seeking electronic health records and medication logs stored in the hospital's combined multipatient database. The hospital objected that the data required custom queries and redactions. The court ordered production because the integrated database qualified as a data compilation that the hospital could translate into a usable electronic format.
Market Data Report in Contract Dispute
Dawson Steel sued Desert Oil for breach of a supply agreement. Dawson offered a subscription analytics report compiling average commodity prices from comparable transactions. A broker testified that industry participants routinely rely on the report. The court admitted the report over hearsay objection because it constituted a data compilation generally relied upon by professionals in the field.

Common questions
Frequently Asked
4
Does a data compilation lose discoverability if it resides in a combined database rather than separate files?+
No. The rule expressly includes data compilations stored in any medium. A responding party must produce responsive information even when it requires queries or redactions to isolate the relevant portions from a multipatient or multiuser system.
Supporting sources
Must a party produce data compilations in a form usable by the requesting party?+
Yes. When the information cannot be used as maintained, the responding party must translate it into a reasonably usable form such as spreadsheets or readable logs rather than raw machine code or limited screenshots.
Supporting sources
Can dynamic dashboards qualify as discoverable data compilations?+
Yes. Electronically stored information includes data compilations in any medium from which information can be obtained. A party cannot avoid production merely because the data exists only in dynamic systems rather than static or printable files.
Supporting sources
Does the hearsay rule bar admission of a data compilation used by professionals in a trade?+
No. Market quotations, lists, directories, and similar compilations are admissible under a hearsay exception when a knowledgeable witness establishes that persons in the relevant occupation generally rely on them.
