Distributed Data Management Architecture (DDM) is IBM's open, published software architecture for creating, managing and accessing data on a remote computer. DDM was initially designed to support record-oriented files; it was extended to support hierarchical directories, stream-oriented files, queues, and system command processing; it was further extended to be the base of IBM's Distributed ...
In financial economics, the dividend discount model (DDM) is a method of valuing the price of a company's capital stock or business value based on the assertion that intrinsic value is determined by the sum of future cash flows from dividend payments to shareholders, discounted back to their present value.
Drift Diffusion Model, a method used in psychological choice testing Maltosides (n-Dodecyl β-D-Maltopyranoside), a detergent used when purifying membrane proteins Transport, vehicular, engines, motors
Data diffusion machine (DDM) is a historical virtual shared memory architecture where data is free to migrate through the machine. Shared memory machines are convenient for programming but do not scale beyond tens of processors. The DDM overcomes this problem by providing a virtual memory abstraction on top of a distributed memory machine. A ...
The drift-diffusion model (DDM) is a well defined [19] model, that is proposed to implement an optimal decision policy for 2AFC. [20] It is the continuous analog of a random walk model. [ 7 ] The DDM assumes that in a 2AFC task, the subject is accumulating evidence for one or other of the alternatives at each time step, and integrating that ...
The system file is an Adabas file reserved for use by Natural, which contains, but is not limited to, the following: All Natural programs, both in source format (programs) and in object format (compiled), grouped in libraries;
The difference between a distributed file system and a distributed data store is that a distributed file system allows files to be accessed using the same interfaces and semantics as local files – for example, mounting/unmounting, listing directories, read/write at byte boundaries, system's native permission model. Distributed data stores, by ...
With DDM (Dynamic Device Mapping) Technology, the communication between shared peripherals and all connected systems are maintained 100% of the time, even as a user switches between the KVM ports. This makes generic device emulation unnecessary as the DDM allows each connected computer system to believe all connected I/O devices are remaining ...
