LittleD: A relational database for embedded devices and sensors nodes

LittleD is a relational database for microprocessor devices, using as little as 1kB of RAM for most queries. LittleD supports SELECT-FROM-WHERE syntax, including inner joins, projections, and selections over arbitrary expressions. LittleD also has support for CREATE TABLE and INSERT statements.Share on Twitter ∙ Share on Facebook

IonDB: A key-value datastore for resource constrained systems

Currently in the Arduino world, there doesn’t exist an associative array or map implementation that is both easy to use and performance competitive. There also is little support for disk based storage options that don’t involve writing it yourself. IonDB is fast, functional, and offers disk based storage out of the box.Share on Twitter ∙ Share on Facebook
