RELATED CONCEPT
Double-Entry Ledger
A double-entry ledger is an accounting system where every financial transaction requires at least two balanced entries: a debit to one or more accounts and an equal credit to one or more accounts.
FINANCIAL INFRASTRUCTURE CONCEPT
Core Banking
Core banking refers to the centralized back-end software suite and authoritative database systems that manage an institution critical banking operations, customer accounts, interest, and ledgers.
Architectural context & analysis
The core acts as the single source of truth for account balances, loan servicing, deposit accounting, transaction processing, and regulatory reporting.
Next-generation core systems feature modular, API-first microservice architectures that decouple continuous real-time posting engines from legacy batch-processing cycles.
Worked operational scenario
A digital bank deploys a high-throughput core banking engine capable of processing 10,000 balanced ledger updates per second with zero downtime deployments.
Implementation considerations & controls
Prioritize strict ACID transactional boundaries over distributed eventual consistency when designing core accounting tables and balances.
