Formally, a “database” refers to a set of related data and the way it is structured or organized. Access to this data is usually provided by a “database management system” (DBMS) consisting of 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). The DBMS provides various functions that allow entry, storage and retrieval of large quantities of information as well as provide ways to manage how that information is organized.
Scripting Language :
A scripting language or script language is a programming language that supports scripts, programs written for a special run-time environment that can interpret (rather than compile) and automate the execution of tasks that could alternatively be executed one-by-one by a human operator.
Typically, a client is a computer application, such as a web browser, that runs on a user’s local computer or workstation and connects to a server as necessary. Operations may be performed client-side because they require access to information or functionality that is available on the client but not on the server, because the user needs to observe them or provide input, or because the server lacks the processing power to perform the operations in a timely manner for all of the clients it serves. Additionally, if operations can be performed by the client, without sending data over the network, they may take less time, use less bandwidth, and incur a lesser security risk.
The term platform-independent model is most frequently used in the context of the model-driven architecture approach.Platform independent is program running on different processors like intel, AMD, Sun Micro Systems etc.; This model-driven architecture approach corresponds to the Object Management Group vision of Model Driven Engineering.
The main idea is that it should be possible to use a Model Transformation Language to transform a Platform-independent model into a Platform-specific model. In order to achieve this transformation, one can use a language compliant to the newly defined QVT standard. Examples of such languages are VIATRA or ATLAS Transformation Language. It means execution of the program is not restricted by the type of o/s used.
