cproto generates function prototypes for functions defined in the specified C source files to the standard output. The function definitions may be in K&R or ANSI C style, or in the lint library form. cproto can also convert function definitions in the specified files from the K&R style to the ANSI C style.
JaxMe is a Java/XML binding framework based on SAX2. It consists of a set of code generators that read an XML schema and generate code for parsing conformant XML documents into corresponding Java objects, saving those objects into a database or, vice versa, reading such Java objects from a database and converting them into XML. JaxMe supports namespaces, relational databases, and Tamino. JaxMe comes with an integrated application framework and a generator for EJB entity beans with BMP (bean managed persistence).

GNU Lightning is a library that generates assembly language code at run time. It is very fast, making it ideal for Just-In-Time compilers, and it abstracts over the target CPU, as it exposes to the clients a standardized RISC instruction set (inspired by the MIPS and SPARC chips).
DbDesigner is a useful tool for constructing databases in an intuitive and easy-to-use environment, where you have a visual representation of the tables and relations contained in your project. You can quickly see the fields in a table or how each table relates to the others. After you are finished, it can export the schema of the database into an .sql script, or directly connect to a database backend and build it there. It can also import already existing databases from .sql scripts or db backends. It can save your project into its native format (XML) so all information is kept, and it has a plugin architecture to be easily extensible to work with many database servers (it comes with 2 plugins for PostgreSQL and MySQL).
