Mantle is a framework for mapping raw data structures and JSON into typed model objects for Cocoa and Cocoa Touch applications. It serves as a data serialization engine and JSON data mapper that transforms dictionaries and arrays into structured model objects. The framework distinguishes itself through an Objective-C persistence layer that manages model disk archiving via keyed archivers. It includes specialized logic for model version management, allowing outdated archived data structures to be upgraded to match current schemas during deserialization. The project covers a broad range of dat

RestKit is an iOS REST API integration framework used to connect Apple platform applications to web services. It centers on RESTful resource modeling, transforming remote API data structures into typed local objects and database entities. The framework provides capabilities for remote data persistence by caching web service resources in a local database to enable offline access. It also handles network data serialization, using pluggable parsers to convert JSON or XML responses into application data models. Additional functionality includes multipart file uploading for sending binary data an

This project is a Spring Cloud microservices boilerplate and distributed system infrastructure designed to accelerate the development of enterprise Java applications. It provides a reference architecture that combines a Java backend with a decoupled Vue.js frontend framework. The system includes a complete e-commerce reference implementation, featuring a digital storefront with a full shopping workflow and a backend operations platform for business management. It also integrates OAuth 2.0 for identity management, supporting stateless authentication and third-party login services. The infrast

This project is a Spring Boot API starter kit and RESTful project skeleton designed for building backend services. It provides a foundational codebase that implements a layered service architecture and standardized directory structures to organize controllers, services, and data mappers. The project features a MyBatis CRUD boilerplate generator that automates the creation of models and controllers from database tables using customizable templates. It includes a security framework for protecting endpoints via interface signature authentication to verify user identity and request authorization.

Mapper is a MyBatis-specific library that provides annotation-driven object-relational mapping, enabling single-table CRUD operations without writing SQL or XML. It uses Java reflection and field-level annotations to map entity fields to database columns, configure primary key generation strategies, and generate mapper interfaces and model classes from database schemas. The library distinguishes itself through several practical capabilities. It includes a safe operation guard that blocks delete and update calls lacking query conditions, preventing accidental full-table modifications. Its exam

dplyr is an R data manipulation library that provides a grammar for transforming tabular data frames. It functions as an in-memory data frame processor and a relational data algebra tool, using a consistent set of verbs to filter, select, and summarize data. The project includes a SQL translation engine that converts high-level data manipulation expressions into optimized queries. This allows users to perform transformations directly on remote relational databases and cloud storage without pulling data locally. The library covers a broad range of tabular operations, including column mutation

Dieses Projekt ist eine Bibliothek für Objektpersistenz und eine Abstraktionsschicht für Data-Mapper. Es bietet eine Reihe gemeinsamer Schnittstellen und Basisklassen, die darauf ausgelegt sind, die Domänenlogik von spezifischen Object-Mapper-Implementierungen zu entkoppeln und die Geschäftslogik von der zugrunde liegenden Datenzugriffsschicht zu trennen. Die Bibliothek enthält ein Tool zur Verwaltung und Migration von Datenbankschemata für das Definieren, Versionieren und Bereitstellen inkrementeller Updates von Datenbankstrukturen in verschiedenen Umgebungen. Sie fungiert zudem als Dokumentendatenbank-Mapper, der Objektzustände für Speicherung und Abruf in strukturierte Dokumentformate übersetzt. Das System deckt ein breites Spektrum an Persistenzfunktionen ab, einschließlich der Verwaltung von Objektsammlungen und der Möglichkeit, Objekte ohne Aufruf von Konstruktoren zu instanziieren, um den Zustand wiederherzustellen. Zudem bietet es Dienstprogramme für die Versionierung von Datenbankschemata und das Dispatching benutzerdefinierter Ereignisse, damit entkoppelte Komponenten auf Persistenzänderungen reagieren können.
