ATM uses a connection-oriented model in which a virtual circuit must be established between two endpoints before the actual data exchange begins. ATM still plays a role in the last mile , which is the connection between an Internet service provider and the home user.
In the field of programming a data transfer object (DTO [1] [2]) is an object that carries data between processes. The motivation for its use is that communication between processes is usually done resorting to remote interfaces (e.g., web services), where each call is an expensive operation. [ 2 ]
A relational database (RDB [1]) is a database based on the relational model of data, as proposed by E. F. Codd in 1970. [2] A database management system used to maintain relational databases is a relational database management system ( RDBMS ).
This kind of model could be implemented by creating a class of data access methods that directly reference a corresponding set of database stored procedures. Another implementation could potentially retrieve or write records to or from a file system. The DAL hides this complexity of the underlying data store from the external world.
Java Database Connectivity (JDBC) is an application programming interface (API) for the Java programming language which defines how a client may access a database.It is a Java-based data access technology used for Java database connectivity.
An approach to connections which makes direct use of the notion of transport of "data" (whatever that may be) is the Ehresmann connection. The most abstract approach may be that suggested by Alexander Grothendieck , where a Grothendieck connection is seen as descent data from infinitesimal neighbourhoods of the diagonal ; see ( Osserman 2004 ).
Formally, a "database" refers to a set of related data accessed through the use of a "database management system" (DBMS), which is an integrated set of computer software that allows users to interact with one or more databases and provides access to all of the data contained in the database (although restrictions may exist that limit access to particular data).
In computing, the USB human interface device class (USB HID class) is a part of the USB specification for computer peripherals: it specifies a device class (a type of computer hardware) for human interface devices such as keyboards, mice, game controllers and alphanumeric display devices.
