Mapper

XML Mapper is the Swiss knife for transforming and mapping XML files. This is an updated version of the XML Mapper that ships with RAD Studio. At design time, it defines the mappings between generic XML documents and the data packets that client datasets use. Each mapping describes the correspondences between the nodes of an XML document and the fields in a data packet. You can define mappings from an existing XML schema (or document) to a client dataset that you define, from an existing data packet to a new XML schema you define, or between an existing XML schema and an existing data packet.

Trysil is an Object-Relational Mapper (ORM) for Delphi, open-source (on GitHub), that simplifies database management, allowing you to define entity classes and map them to DB tables (Firebird, PostgreSQL, SQLite, SQL Server), handling queries, inserts, and updates through a TTContext, also supporting lazy loading and events. To use it, you need to download it from GitHub (search for the davidlastrucci/Trysil repository) and integrate the code into your Delphi applications to map your classes to the data.
