R-Tree (Spatial Indexing) – R-trees are tree data structures used for spatial access methods, i.e., for indexing multi-dimensional information such as for example geographic coordinates, rectangles or polygons. The R-tree had been proposed by Antonin Guttman in 1984 and it has discovered use that is significant both theoretical and used contexts. A typical real-world use for an R-tree may be to keep spatial things such as for instance restaurant places or the polygons that typical maps are constructed of roads, structures, outlines of lakes, coastlines, etc. then find responses quickly to questions such as „Find all museums within 2 kilometer of my current location“, „retrieve all road portions within 2 kilometer of my location“ (to show them in a navigation system) or „find the nearest gasoline place“ (while not using roadways under consideration).
Runtime – a percentage of the DBMS that is included inside the https://datingmentor.org/escort/fairfield/ procedure space of a credit card applicatoin system.
Scalability – a computer computer pc software system is scalable whenever its performance and system that is overall continues to improve because more computing resources are created readily available becausage of its usage. This often will come in the form of the true range CPUs and cores obtainable in the pc by which the application system is run.
Scalar Function – Either a integral SQL function or a function that is user-defined returns an individual value computed only through the values of any necessary arguments at that time the event is known as.
Schema – A representation of this framework of the database. It may be graphical or textual. Graphical representations typically involve the usage bins that represent database tables and arrows that represent inter-table relationships. „RTOS – a typical abbreviation for real-time operating-system. Raima Database Manager runs of many RTOS, like VxWorks, Integrity, Embedded Linux and QNX.“ weiterlesen
