Libgda is a (relatively small) database access library. It provides a wrapper like ODBC but with more features for accessing several database engines, a general data model for use with CSV or XML files, a metadata extractor that retrieves information about database objects in a common way, and a SQL console application (like mysql, psql or sqlite3 consoles).
Capstone is a disassembly framework with the target of becoming the ultimate disasm engine for binary analysis and reversing in the security community. Running on Windows, Mac OS X, Linux, FreeBSD, OpenBSD, and Solaris, it can disassemble ARM, ARM64 (ARMv8), MIPS, PPC, and x86 architectures. Capstone provides rich details about disassembled instructions along with useful semantic information.
