The primary business model for closed-source software involves the use of constraints on what can be done with the software and the restriction of access to the original source code. [6] This can result in a form of imposed artificial scarcity on a product that is otherwise very easy to copy and redistribute. The result is that an end-user is ...
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).
This is a list of free and open-source software (FOSS) packages, computer software licensed under free software licenses and open-source licenses.Software that fits the Free Software Definition may be more appropriately called free software; the GNU project in particular objects to their works being referred to as open-source.

Shareware is closed-source software whose owner encourages redistribution at no cost, but which the user sometimes must pay to use after a trial period. The fee usually allows use by a single user or computer. In some cases, software features are restricted during or after the trial period, a practice sometimes called crippleware.
Data exchange routines and automatisms are the most important reason to develop a CSDB, to ensure a process reliability. The import and export routines can be fully automated or be performed via CSDB operator. The components of a Data exchange package are for example: – one data dispatch note (DDN) – a certain amount of DataModules (DMs) and
Open architecture is a type of computer architecture or software architecture intended to make adding, upgrading, and swapping components with other computers easy. [1] For example, the IBM PC, [2] Amiga 2000 [3] and Apple IIe have an open architecture supporting plug-in cards, whereas the Apple IIc computer has a closed architecture.
Entity–relationship modeling is a relational schema database modeling method, used in software engineering to produce a type of conceptual data model (or semantic data model) of a system, often a relational database, and its requirements in a top-down fashion.
The name is commonly used when creating a query to the database. The Database Source Name (DSN) does not have to be the same as the filename for the database. For example, a database file named "friends.mdb" could be set up with a DSN of "school". Then DSN "school" would then be used to refer to the database when performing a query. Data Source ...
