1C:Enterprise is a development platform and runtime environment for creating and deploying business applications. Developed by 1C Company, it is widely used in Russia and the Commonwealth of Independent States for enterprise resource planning (ERP), accounting, retail, manufacturing, and other business domains. The platform combines a proprietary programming language, a metadata-driven development environment, and a server-based runtime that stores data in an Infobase database.

Applications are built as configurations, which define objects such as catalogs, documents, and registers, and include logic, reports, and user interfaces. The runtime supports multiple access modes: a thick Windows client, a web client using HTML5, and mobile clients, enabling deployment on-premises or in the cloud.

Programming language and development tools: The 1C:Enterprise language is a domain-specific language used to implement business logic and data processing within configurations. Development is performed in the 1C:Developer tools IDE, with a visual designer for configuration metadata, forms, and reports.

Data storage and integration: The platform uses the Infobase DBMS, a built-in database engine designed for business data and transactional workloads. Configurations can integrate with external systems through web services and common data exchange formats.

Market and usage: The platform is widely adopted in Russia and the CIS for ERP, accounting, retail chains, and public sector solutions. It has a large ecosystem of official configurations and partner-made solutions, with a licensing model based on users, devices, or subscriptions, and options for on-premises or cloud deployment.
