sqlx is a set of extensions for the Go database/sql package that reduces boilerplate code by automating the mapping of database query results directly into structs and slices. It provides a wrapper around standard database types to eliminate manual row scanning and repetitive error handling. The project distinguishes itself through named parameter binding and query placeholder rebinding, which translate generic markers into driver-specific symbols. It also enables dynamic SQL execution by allowing the application to read and execute SQL statements directly from the filesystem. The library co

Presto is a distributed SQL query engine designed for high-performance analytical processing across heterogeneous data sources. It functions as a data federation platform and massively parallel processing engine, allowing users to execute interactive queries against diverse storage systems without requiring data migration. By mapping remote metadata and structures to a unified relational namespace, it enables seamless cross-platform analysis through a standard SQL interface. The engine distinguishes itself through a pluggable connector architecture and a shared-nothing distributed processing

RoboMongo is a cross-platform database manager and graphical interface for administering MongoDB databases. It serves as a shell integrated development environment and query tool for managing NoSQL data stores and exploring collections across multiple server instances. The application provides a visual environment for writing and executing modern JavaScript scripts and native shell commands. It includes capabilities for running aggregate queries with paginated results and supports side-by-side views for comparing data outputs. The tool covers remote database connectivity through SSH tunnelin

Any-rule is a multi-platform regular expression tool that provides a curated catalog of over 70 ready-to-use patterns for validating and extracting common data formats. The project separates its static regex collection from editor-specific plugins, allowing the same pattern library to be accessed through VS Code, IntelliJ IDEA, Alfred Workflow, and a web interface. The tool enables keyword-based pattern retrieval, letting users search for the correct regex by typing descriptive terms rather than remembering exact syntax. It covers a broad range of validation needs including email addresses, U

This is an arbitrary-precision decimal library and fixed-point math implementation used to eliminate floating-point rounding errors. It provides tools for high-precision arithmetic, a numerical analysis toolkit, and a database decimal mapper to ensure numerical accuracy in financial and scientific calculations. The library includes specialized serialization tools to transform high-precision numbers into SQL database types, JSON, and XML formats without losing precision. It also implements a variety of rounding strategies, including banker and cash rounding, and provides mechanisms for decimal
