massive-js - A data mapper for Node.js and PostgreSQL.

•    Javascript

---

Massive.js is a data mapper for Node.js that goes all in on PostgreSQL and fully embraces the power and flexibility of the SQL language and relational metaphors. Providing minimal abstractions for the interfaces and tools you already use, its goal is to do just enough to make working with your data as easy and intuitive as possible, then get out of your way. Massive is not an object-relational mapper (ORM)! It doesn't use models, it doesn't track state, and it doesn't limit you to a single entity-based metaphor for accessing and persisting data. Massive connects to your database and introspects its schemas to build an API for the data model you already have: your tables, views, functions, and easily-modified SQL scripts.

datamappify - Compose, decouple and manage domain logic and data persistence separately

•    Ruby

---

Datamappify is no longer being maintained. It started off with a noble goal, unfortunately due to it being on the critical path of our project, we have decided not to continue developing it given the lack of development time from me. Feel free to read the README and browse the code, I still believe in the solutions for this particular domain.

With Cortex you can create generic apps, that work with any DB of the users choice, no matter if it's Postgre, MongoDB or even none. You can also mash-up multiple engines, use them simultaneous or link models of different DB engines together (in development). It's great for fast and easy data abstraction and offers a bunch of useful filter possibilities.

derivejs - DeriveJS is a reactive ODM - Object Document Mapper - framework, a "wrapper" around a database, that removes all the hassle of data-persistence by handling it transparently in the background, in a DRY manner

•    Javascript

---

DeriveJS lets you manipulate and create Javascript data objects, while automatically and transparently persisting and updating them on a database (such as MongoDB), in the background, without any additional hassle or code. It wraps your data classes and objects with Javascript Proxies, "tapping-in" to native operations such as creating instances (using the normal new operator), and updating property values (using the normal assignment operator =), and then handling passing database calls and operations to the database in the background, while leveraging MongoDB's bulk operations capabilities, orchestrating them in a smart, efficient way, to save unnecessary calls to the DB engine, and running bulk operations in fixed (settable) intervals. The background engine is mostly handled transparently by a module called SyncManager.
