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. Unlike slow SQL databases, 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). Further, they can automatically
|
|
support infinite undo/redo, greatly simplifying many applications.
|
|
|
|
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 support over 4 billion objects
|
|
of a given class with 32-bit object references.
