DataDraw is an ultra-fast persistent database for high performance programs
written in C. It's so fast that many programs keep all their data in a
DataDraw database, even while being manipulated in inner loops of compute
intensive applications. DataDraw databases are compiled, and directly link
into your C programs. DataDraw databases are resident in memory, making data
manipulation even faster than if they were stored in native C data structures
(really).
DataDraw databases can be persistent. Modifications to persistent data are
written to disk as they are made, which of course dramatically slows write
times. However, DataDraw databases can also be volatile. Volatile databases
exist only in memory, and only for the duration that your program needs it.
Volatile databases can be directly manipulated faster than C structures, since
data is better organized in memory to optimize cache performance
DataDraw supports modular design. An application can have one or more common
persistent databases, and multiple volatile databases to support various tools'
data structures. Classes in a tool's database can extend classes in the common
database.
DataDraw is also 64-bit optimized, allowing programs to run much faster and in
less memory than standard C programs using 64-bit pointers. This is because
DataDraw databases supports over 4 billion objects of a given class with 32-bit
object references.
