RTOS – a abbreviation that is common real-time operating-system. Raima Database Manager operates of many RTOS, like VxWorks, Integrity, Embedded Linux and QNX.

R-Tree (Spatial Indexing) – R-trees are tree data structures used for spatial access methods, for example., for indexing multi-dimensional information such as for instance geographic coordinates, rectangles or polygons. The R-tree was proposed by Antonin Guttman in 1984 and has now discovered use that is significant both theoretical and used contexts. A typical real-world use for an R-tree could be to keep spatial items such as for example restaurant places or even the polygons that typical maps are constructed of roads, structures, outlines of lakes, coastlines, etc. then find answers quickly to inquiries such as „Find all museums within 2 kilometer of my current location”, „retrieve all road portions within 2 kilometer of my location” (to produce them in a navigation system) or „find the gas station that is nearest” (while not using roads into consideration).

Runtime – a percentage of the DBMS this is certainly included inside the process room of a credit card applicatoin system.

Scalability – a computer pc software system is scalable whenever its performance and general system throughput continues to improve because more computing resources are created designed because of its usage. This frequently will come in the type of the wide range of CPUs and cores available in the pc upon which the program system is run.

Scalar Function – Either a integral SQL function or a function that is user-defined returns an individual value computed just through the values of any necessary arguments at that time the function is named.

Schema – A representation of this framework of the database. It might be graphical or textual. Graphical representations typically include the employment of bins that represent database tables and arrows that represent inter-table relationships. Textual schema representations use Database Definition Language (DDL) statements to explain a database design.

Searched Update/Delete – An SQL up-date or delete statement in that the rows become updated/deleted are the ones for that the conditional phrase specified when you look at the WHEREIN clause holds true.

Seat – a duplicate of an item, or some of its elements, set up for a single device.

Semaphore – A primitive computing procedure that can be used to synchronize provided use of information. Often called a „mutex” meaning a „mutually exclusive area.” Semaphores control concurrent use of data by limiting usage of critical chapters of code that manipulate that information.

Server ( computer Software) – A Seat that resides for a solitary Server machine and is effective at accepting connections from 1 or higher Seats living on Client devices.

Set – a way used to implement the relationship that is one-to-many between two tables according to their international and primary key declarations. The term „set” originates from the CODASYL system Model meaning. A group can be utilized in a database that is relational an owner (main key) dining table and a part (foreign key) table where every one of the user dining table rows which can be pertaining to the exact same owner dining dining table line are linked along with a connected list. See Wikipedia

Snapshot Isolation – each time a snapshot regarding the database is taken, an example regarding the database is frozen and concurrent reads are permitted to take place on that snapshot. Database writes are permitted to continue while reads from the snapshot are occurring.

Source Code (Raima) – The English language source rule variation of something, and any comments that are accompanying other programmer Documentation, given by Raima to Licensee pursuant to your regards to an understanding.

See Wikipedia

SQL PL – A SQL based program coding language. This permits for the SQL programmer to make use of development constructs like factors, conditionals and loops solely with the use of SQL statements.

Stack – A stack is just a conceptual framework consisting of a set of homogeneous elements and it is on the basis of the concept of last in very very first www.datingmentor.org/escort/greensboro/ out (LIFO). It’s a commonly utilized data that are abstract with two major operations, particularly push and pop. Drive and pop music are executed in the topmost element, that will be the product of late put into the stack. The push procedure adds a component into the stack whilst the pop music procedure eliminates a component from the position that is top. The stack concept can be used in memory and programming company in computer systems. Stored Procedure – a known as and optionally parameterized put together collection of SQL database access statements which can be performed being a product via a call to your kept procedure.
