A lightweight database-management system (DBMS) is based on a dynamic microservices architecture that implements each granular DBMS feature or function as a distinct, independently executable microservice. The DBMS's Parser front-end responds to each incoming query by selecting the first bind-time database feature needed to process the query. The Parser forwards its selection through a Channel-Binding subsystem to an Event Services Activation subsystem that activates a corresponding microservice to perform the selected feature. The first feature then selects the next required bind-time feature for activation, and this process continues sequentially until all required bind-time microservices have been identified, activated, and run. Runtime query-processing features are then sequentially selected in a similar manner. However, each selected runtime microservice is preloaded but not run.

For this purpose, the internal-combustion engine control device includes a physical quantity detection unit that detects a physical quantity that fluctuates output of the internal-combustion engine, an output fluctuation value calculation unit that calculates an output fluctuation value for each cylinder based on a detection result of the physical quantity detection unit, and a state determination unit that determines a transient operation state or a steady operation state based on a difference or a ratio between a first output fluctuation value of a predetermined first cylinder and a second output fluctuation value of a predetermined second cylinder calculated by the output fluctuation value calculation unit. Since combustion failure determination is performed in a section determined as the steady state, it is possible to accurately determine a combustion failure state of an air-fuel mixture of a cylinder even in a case where operation is switched between the steady operation state and the transient operation state.
