<title>RDM Server - Raima's client/server DBMS originally released in 1993, called RDS (Raima Database Server), Velocis, and lastly RDM Server. Nevertheless supported for current clients.</title>
<p>Read-only deal - A Multi-Version Concurrency Control (MVCC) feature that enables database information to be read by one procedure without blocking another procedure's modification of the data that are same. Often known as a "snapshot."</p>
<p>Real-time - a environment that is real-time one for which particular tasks needs to be going  to perform inside  a specified time period.<!--more--> For a DBMS to be viewed certainly real-time, it should  be in a position to perform certain database-related tasks in an occasion which can be deterministically demonstratedвЂ”i.e., the case execution time that is worst are demonstrated. Must be general-purpose DBMS relates to dynamic information when the sizes of tables differ as time passes, and since DBMS reaction times rely on the actual quantity of information become prepared they are unable to be looked at real-time. That is real additionally for RDM. It's real-time friendly, since it is fast, has a little footprint and contains features (such as for instance digital tables and in-memory storage space) that enable that it is utilized in useful means in a real-time application.</p>
<h2>Record Instance/Occurrence - One group of associated information industry values related to a record that is specific to an SQL row.</h2>

Just like a C struct, an archive kind is defined by a couple of closely associated information areas.</p>
<p>Referential Integrity - an ailment where the international key column values in most associated with the rows in a single    table have actually matching rows within the referenced primary key table. Referential integrity is maintained by SQL throughout the processing of a INSERT and DELETE statement and any UPDATE statement that modifies an international or primary value that is key.</p>
<p>Relational Model - A database by which inter-table relationships are arranged mainly through common data columns, which define a one-to-many relationship from  a line associated with the main key dining  dining table plus one or even more rows associated with the matching international key table. Equi-joins relate tables which have matching primary/foreign key values, but other comparisons (relationships) could be defined. As well as describing how a database tables are associated, the relational model additionally describes just just how the related data could be accessed and manipulated. SQL is considered the most widely used model database language that is relational. See Wikipedia </p>
<p>Remote Procedure Phone - a way of interprocess interaction the place where  a function living within another procedure is named as though it's a regional (in-process) function. The strategy is implemented through an area proxy function and a stub function that is remote. Parameter values are marshalled into  a block of information that may be sent through the proxy to your stub for demarshalling and calling the real function. Return values are prepared when you look at the way that is same input values.</p>
<h2>Replication - a procedure where chosen adjustments in a master database is replicated (re-played) into another database.</h2>

As an example, within the query choose * from book where bookid = 'austen013px' the relational phrase bookid = 'austen013px' has  a limitation element corresponding to .003 (only 1 away from 3213px rows will satisfy this phrase).</p>
<p>Result Set - the entire pair of rows this is certainly came back by way of  A select that is particular statement.</p>
<p>Rollback - a procedure, often done by  the SQL ROLLBACK statement, that discards all the noticeable modifications produced by all INSERT, MODIFY and DELETE statements which have been executed considering that the most recently started deal (  e.g., BEGIN DEAL statement).</p>
<p>Line - One group of associated values for several for the columns declared in a provided dining  dining table. Also referred to as a record event.</p>
