Cursor – an accumulation of rows grouped by typical requirements (key series, set membership, SELECT outcome set) which can be navigated and updated.
Information Type – the fundamental sorts of information that could be saved in a line. The information types that are offered in RDM SQL are: char, wchar, varchar, wvarchar, binary, varbinary, boolean, tinyint, smallint, integer, bigint, genuine, float, dual, date, time, timestamp, long varbinary, long varchar, and long wvarchar.
Database example – a completely independent database that stocks exactly the same schema as another database. Utilized only in RDM.
db_VISTA – Original title from 1984 when it comes to Raima DBMS item now called RDM.
DDL – Database Definition Language.
Deadlock – a scenario by which resources (for example. hair) take place by several connections which can be each required by one other connections so they are stuck in a wait loop that is infinite. For instance, connection 1 has a lock on table1 and it is asking for a lock on table2 this is certainly presently held by connection 2, that is also requesting a lock on table1. Development practices could be used to avoid deadlocks from occurring.
Debugger – something utilized to evaluate and debug computer pc software. An average remote debugger operates on a bunch computer and links towards the target through a serial port or higher a community. Utilising the debugger, you escort services in Alexandria can download software towards the target for instant execution. You may also set breakpoints within the rule and examine the articles of particular memory areas and registers.
Deterministic – a feature of a element of rule whereby the limitation in the 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 for which information is distributed among multiple 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 often considered a huge grid of information collection products, needing distributed database functionality to handle.
DLL – Dynamic Link Library. A library of associated functions that aren’t packed into memory until the application calls them program. All RDM APIs are contained in DLLs on those systems that help them ( ag e.g., MS-Windows). They are often called provided libraries on some systems.
DML – Database Manipulation Language. In SQL, such statements as IMPROVE, INSERT and DELETE are thought DML.
Paperwork – All product-related materials, specs, technical manuals, individual manuals, movement diagrams, file explanations, or other written information either incorporated with services and products or elsewhere. Raima’s paperwork is online.
Domain – an name that is alternate a base data kind that is defined utilizing the RDM SQL create domain statement.
Durability – The home of a deal where the DBMS guarantees that most transactions that are committed endure any type of system failure.
Dynamic DDL – the capacity to replace the concept of a database (its schema) after information was saved in the database and never have to make the database restructure or off-line its files.
Edge Computing – Advantage computing relates to the computing infrastructure in the side of the community, near to the sourced elements of information. Edge computing reduces the communications bandwidth needed between sensors plus the datacenter. Databases with tiny footprints RDM that is e.g are for advantage computing.
Embedded Database – An embedded database could be the mix of a database additionally the database pc software which typically resides within a credit card applicatoin. The database holds information therefore the pc computer software control the database to access or shop information. The application form pc pc software, or even the user-interface, then accesses the database and gift suggestions that information in method which can be possible for the consumer to interpret and comprehend.
Encryption – The encoding of information such that it may not be comprehended by way of a human being reader. This often calls for the utilization of an encryption key. a typical encryption algorithm is known as AES, which makes use of encryption secrets of 128, 192 or 256 bits. See Wikipedia
End-User – An entity that licenses a software for the use that is own from or its extra Reseller.
Fog Computing – An architecture that distributes computing, storage, and networking nearer to users, and anywhere across the Cloud-to-Thing continuum. Fog computing is essential to perform IoT, IIoT, 5G and AI applications.
Foreign Key – more than one columns in a table meant to contain only values that match the associated primary/unique key column(s) when you look at the referenced table. Foreign and main tips explicitly determine the direct relationships between tables. Referential Integrity is maintained whenever every foreign key describes one and just one existing key that is primary.
Geospatial datatypes – information kinds that are especially optimized for storage space of geographical coordinate based data.
Grouped Lock Request – just one procedure that demands hair on a lot more than one dining dining dining table or rows at the same time. Either all or none associated with requested locks will be given. Issuing a grouped lock request at the start of a transaction that features every one of the tables/rows that will be accessed by potentially the deal guarantees that the deadlock will maybe not take place.
GUI – Graphical Interface.
Handle – A computer software recognition adjustable that is employed to recognize and handle the context connected with a computing that is particular or thread. As an example, SQL makes use of handles for every single individual connection (connection handle) and SQL statement (statement handle) on top of other things.
