Perseus was a vacuum tube (valve) computer built by Ferranti Ltd of Great Britain. It was a development of the Ferranti Pegasus computer for large-scale data processing. [ 1 ] Perseus, which was one of Ferranti's computer systems that included Orion and Sirius , [ 2 ] was the company's first production machine marketed towards commercial users ...
Relational (SQL, ODBC, JDBC) in-memory database system originally developed for use in SCADA and embedded systems, but used in a variety of other applications including financial systems. Supports data durability via snapshots and journal logging, and high availability via a hot-standby. First released in 1993; version 8.7 released in March ...
Perseus has nowadays branched into other projects: the Scaife Viewer, which is the first phase of the work towards Perseus 5.0, [11] the Perseus Catalog, [1] [12] [13] which provides links to the digital editions not hosted by the Perseus Library, the Perseids Project, [1] which aims to support access to Classics scholarship by providing tools ...
The name is commonly used when creating a query to the database. The Database Source Name (DSN) does not have to be the same as the filename for the database. For example, a database file named "friends.mdb" could be set up with a DSN of "school". Then DSN "school" would then be used to refer to the database when performing a query. Data Source ...
Source Code Control System (SCCS) is a version control system designed to track changes in source code and other text files during the development of a piece of software. . This allows the user to retrieve any of the previous versions of the original source code and the changes which are st
A number of intrinsic functions were inserted by the compiler to ensure the program and database used the same definition of database structures. Originally, DMSII maintained a data dictionary that the application programmer referenced in its source code. The source for the data structures was maintained in an ordinary CANDE source file. That ...
The OS 2200 database managers are all part of the Universal Data System (UDS). UDS provides a common control structure for multiple different data models. Flat files (sequential, multi-keyed indexed sequential, MSAM, and fixed-block), [1] network, [2] and relational [3] data models all share a common locking, recovery, and clustering mechanism.
IBM VisualAge Java is an example of an integrated development environment implementing SCID features. A more recent example of Source Code in Database is CodeOntology, an open source tool and RDF database of Java source code that supports advanced SPARQL queries, such as Select recursive methods or Select methods that compute the cube root of a double.
