SystemTechniques · 25Primitives · 99 pharmacy-management Deterministic simulation testingdistributed · medium: Run the whole system in one thread under a seeded scheduler with simulated network, disk and clock, so every failure replays from its seed.›Durable workflow executiondistributed · medium: Ordinary code made crash-proof by logging every side-effect result and replaying the code from that log; activities run at least once, workflow logic must be deterministic.›Primary-backup replicationdistributed · medium: One node orders all writes and ships them to standbys; the acknowledgement rule (none, one, all) sets what a crash loses, and an external arbiter decides who takes over.›Inventory reservationfinance · medium: Reserving stock with TTL holds, release on timeout and no overselling under contentionOrder lifecycle state machinefinance · medium: Order states (new, partial fill, cancel/replace, rejected, expired) with strict transitions and idempotent eventsTerminology code systemsnetworking · medium: Code systems, value sets and concept maps (SNOMED CT, LOINC, ICD) with subsumption queriesInventory policies safety stockoptimization · medium: (s,S), base-stock, EOQ and newsvendor policies with safety stock from demand uncertaintyIdempotency keysfinance · low: Client-chosen unique key per logical operation, stored with a request fingerprint and the final response, so retries replay the first result instead of acting twice.›Fhir resource modelnetworking · low: FHIR resources, references, search parameters and REST interactions for health data exchangeBarcode symbologiesdata-structures · low: Encode/decode 1D and 2D barcodes (Code 128, DataMatrix, QR) with their error correctionHdr histogramdata-structures · low: Log-linear bucketed histograms with bounded relative error for latency percentilesSoft hard limitsembedded · low: Pump drug library with per-drug soft and hard limits on dose rate and concentration, by care area, checked before infusion startsReconciliationfinance · low: Match internal ledger records against bank and processor statements by reference, then amount and date window; every unmatched or mismatched item becomes an exception.›Process supervisionhardware-os · low: A parent process starts services, reaps their exits and restarts them under a delay and burst-limit policy, then stops them with SIGTERM before SIGKILL.›Hl7v2 message parsingnetworking · low: HL7 v2 pipe-delimited segments, escaping, ACKs and MLLP framing for clinical interfacesNcpdp telecommunication claimsnetworking · low: NCPDP Telecommunication claim, reversal and response messages between pharmacy and payer with reject codesX12 edi messagingnetworking · low: ANSI X12 and EDIFACT interchanges: segment/element delimiters, ISA/GS/ST envelopes, control numbers and 997/CONTRL acknowledgementsDual control approvalsecurity · low: Four-eyes / maker-checker approval with quorum policies for sensitive operationsMutual TLSsecurity · low: TLS where the client also proves a certificate key, so every connection carries a verified, rotatable machine identity.›Row-level security (multi-tenant is…security · low: Append a policy predicate to every query inside the database, so a forgotten WHERE tenant_id = ? in application code cannot leak another tenant's rows.›Graceful drainingsystems · low: On a termination signal, stop taking new work, finish in-flight work until a deadline, tell clients to reconnect elsewhere, then exit; clients resume from a token.›Cooperative schedulingconcurrency · low: Green threads/coroutines yielding at await points on a user-space schedulerRecord replaydistributed · low: Record every nondeterministic input (time, randomness, I/O, model and tool outputs, per-tick player input) and re-execute deterministically for debugging, replays and state rebuild+ 18 more techniques+ 83 more primitives
