DDL – Database Definition Language.

Deadlock – a scenario by which resources (for example. hair) take place by several connections which can be each required by one other connections so they are stuck in a wait loop that is infinite. For instance, connection 1 has a lock on table1 and it is asking for a lock on table2 this is certainly presently held by connection 2, that is also requesting a lock on table1. Development practices could be used to avoid deadlocks from occurring.

Debugger – something utilized to evaluate and debug computer pc software. An average remote debugger operates on a bunch computer and links towards the target through a serial port or higher a community. Utilising the debugger, you escort services in Alexandria can download software towards the target for instant execution. You may also set breakpoints within the rule and examine the articles of particular memory areas and registers.

Deterministic – a feature of a element of rule whereby the limitation in the time necessary to execute the rule is famous, or determined, in advance. This is certainly commonly related to real-time computer computer software.

Distributed Database – A database for which information is distributed among multiple computer systems or products (nodes), permitting numerous computer systems to simultaneously access data living on separate nodes. The world wide web of Things (IoT) is often considered a huge grid of information collection products, needing distributed database functionality to handle.

DLL – Dynamic Link Library. A library of associated functions that aren’t packed into memory until the application calls them program. All RDM APIs are contained in DLLs on those systems that help them ( ag e.g., MS-Windows). They are often called provided libraries on some systems.

Fog Computing – An architecture that distributes computing, storage, and networking nearer to users, and anywhere across the Cloud-to-Thing continuum. Fog computing is essential to perform IoT, IIoT, 5G and AI applications.

Foreign Key – more than one columns in a table meant to contain only values that match the associated primary/unique key column(s) when you look at the referenced table.
