Information Type – the fundamental style of information that are stored in a column. The information kinds that are offered in RDM SQL are: char, wchar, varchar, wvarchar, binary, varbinary, boolean, tinyint, smallint, integer, bigint, genuine, float, double, date, time, timestamp, long varbinary, long varchar, and long wvarchar.
Database example – an unbiased database that shares the exact same schema as another database. Utilized only in RDM.
db_VISTA – initial name from 1984 when it comes to Raima DBMS product now called RDM.
DDL – Database Definition Language.
Deadlock – a predicament by which resources (i.e. hair) take place by a couple of connections which can be each required by the other connections in order that they are stuck in a endless hold off cycle. As an example, connection 1 has a lock on table1 and it is asking for a lock on table2 that is presently held by connection 2, that will be additionally asking for a lock on table1 . Development practices may be used to avoid deadlocks from occurring.
Debugger – something utilized to check and debug computer software. An average debugger that is remote on a number computer and links to the target through a serial port or higher a community. Utilising the debugger, you’ll download program to your target for instant execution. You may want to set breakpoints into the code and examine the articles of particular memory locations and registers.
Deterministic – a feature of a portion of rule whereby the limitation regarding the right time necessary to execute the rule is famous, or determined, in advance. This is certainly commonly related to real-time computer computer software.
Distributed Database – A database by which information is distributed among numerous computer systems or products (nodes), permitting numerous computer systems to simultaneously access data living on separate nodes. The world wide web of Things (IoT) is generally considered a grid that is vast of collection devices, needing distributed database functionality to control.
DLL – Dynamic Link Library. A library of associated functions that aren’t packed into memory until they have been called because of the application system. All RDM APIs are contained in DLLs on those systems that help them ( e.g., MS-Windows). They are often called provided libraries on some systems.
DML – Database Manipulation Language. In SQL, such statements as MODIFY, INSERT and DELETE are believed DML.
Documents – All materials that are product-related requirements, technical manuals, individual manuals, movement diagrams, file explanations, or other written information either added to items or perhaps. Raima’s documentation is online.
Domain – an alternative title for a base information kind this is certainly defined utilising the RDM SQL create domain statement.
Durability – The home of the deal where the DBMS guarantees that every committed deals will survive almost any system failure.
Dynamic DDL – the capability to replace the concept of a database (its schema) after information happens to be kept in the database and never have to simply take the database off-line or restructure its files.
Edge Computing – Advantage computing identifies the computing infrastructure in the side of the system, near to the types of information. Side computing reduces the communications bandwidth required between sensors and also the datacenter. Databases with tiny footprints e.g RDM are optimized for advantage computing.
Embedded Database – An embedded database could be the mix of a database in addition to database pc computer software which typically resides within a credit card applicatoin. The database holds information and also the computer pc pc software control the database to access or shop information. The program computer pc software, or the user-interface, then accesses the database and gift suggestions that information in a real means which will be possible for an individual to interpret and comprehend.
Encryption – The encoding of information such that it can not be recognized with a reader that is human. This frequently calls for making use of an encryption key. a typical encryption algorithm is named AES, which utilizes encryption secrets of 128, 192 or 256 bits. See Wikipedia
End-User – An entity that licenses a credit card applicatoin for the use that is own from or its extra Reseller.
Fog Computing – An architecture that distributes computing, storage space, and networking nearer to users, and anywhere across the Cloud-to-Thing continuum. Fog computing is essential to operate IoT, IIoT, 5G and AI applications.
Foreign Key – more than one columns in a dining dining dining table designed to contain only values that match the associated primary/unique key column(s) when you look at the table that is referenced. Foreign and main secrets explicitly determine the direct relationships between tables. Referential Integrity is maintained when every foreign key relates to one and just one current main key.
Geospatial datatypes – information kinds that are particularly optimized for storage space of geographical coordinate based data.
Grouped Lock Request – an individual procedure that demands hair on a lot more than one dining dining table or rows at any given time. Either all or none associated with the locks that are requested be provided. Issuing a grouped lock demand at the start of a deal that features every one of the tables/rows that may potentially be accessed by the deal guarantees that the deadlock will likely not happen.
GUI – Graphical Graphical User Interface.
Manage – A pc software recognition adjustable that can be used to recognize and handle the context connected with a specific computing procedure or thread. As an example, SQL makes use of handles for every single individual connection (connection handle) and SQL statement (statement handle) among other things.
