This article explains the core concepts of low‑code platforms, emphasizing visual editing as a mandatory feature, comparing declarative and imperative approaches, detailing front‑end JSON‑to‑React rendering, reviewing five back‑end storage strategies, discussing business‑logic implementation, workflow engines, and predicting the future evolution of low‑code solutions.
The article explains that Kubernetes’ core value is its universal, extensible declarative API framework rather than containers, walks through API types, CRD extensions, and uses a fruit‑CRD example to show how CRUD operations map to database concepts, concluding that the API is the true engine of Kubernetes.
This article explains the core concepts of low‑code platforms, emphasizing visual editing as a mandatory feature, comparing declarative and imperative approaches, and detailing various front‑end (JSON‑to‑React via amis) and back‑end storage and logic implementations along with future trends.
This article explains the core principles of low‑code platforms, showing how visual (declarative) editing distinguishes low‑code from traditional code, and reviews various frontend and backend implementation schemes—including JSON‑to‑React rendering, storage strategies, JavaScript logic, and workflow engines—while highlighting their advantages and limitations.
This article explains the fundamentals of database transactions, the ACID properties, and how Spring provides both declarative and programmatic transaction support through three core interfaces, detailed configuration examples in XML and Java, and a deep dive into transaction attributes such as isolation, propagation, rollback rules, read‑only mode, and timeout.
This article explains the core principles of Spring transactions, how they rely on database support, demonstrates JDBC transaction steps, introduces Spring's declarative transaction management, compares JDK and CGLIB proxies, and details propagation attributes, isolation levels, and read‑only transaction usage with practical code examples.
This article explains core programming paradigms—imperative, declarative, functional, and object‑oriented—illustrating their concepts, differences, and practical JavaScript examples, while discussing features like first‑class functions, currying, composition, and OOP principles such as encapsulation, inheritance, and polymorphism.
