Object Database
An object database or object-oriented database is a database management system in which information is represented in the form of objects as used in object-oriented programming. Object databases are different from relational databases which are table-oriented. A third type, object–relational databases, is a hybrid of both approaches. Object databases have been considered since the early 1980s. Overview Object-oriented database management systems (OODBMSs) also called ODBMS (Object Database Management System) combine database capabilities with object-oriented programming language capabilities. OODBMSs allow object-oriented programmers to develop the product, store them as objects, and replicate or modify existing objects to make new objects within the OODBMS. Because the database is integrated with the programming language, the programmer can maintain consistency within one environment, in that both the OODBMS and the programming language will use the same model of representa ...

TScript
TScript is an object-oriented embeddable scripting language for C++ that supports hierarchical transient typed variables (TVariable). Its main design criterion is to create a scripting language that can interface with C++, transforming data and returning the result. This enables C++ applications to change their functionality after installation. Hello world example The basic "Hello World!" TScript example. CTScript ts; ts.SetParameter(CTScript::SOURCE_STRING,0,TEXT("main()")); ts.ExecuteStaticMethod(); TVariables The standard variable can be formed as fixed data such as a Boolean, Integer or Decimal and a variable length variable such as an ASCII string, wide character string or a binary string. The type of the data can be used to define variable or the type can be explicitly declared, so for example the code - will create a variable called and assign it the value of zero. An Integer type can also be declared as - and its default value will be set to zero. TVariable are hiera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtuoso Universal Server
Virtuoso Universal Server is a middleware and database engine hybrid that combines the functionality of a traditional relational database management system (RDBMS), object–relational database (ORDBMS), virtual database, RDF, XML, free-text, web application server and file server functionality in a single system. Rather than have dedicated servers for each of the aforementioned functionality realms, Virtuoso is a "universal server"; it enables a single multithreaded server process that implements multiple protocols. The free and open source edition of Virtuoso Universal Server is also known as OpenLink Virtuoso. The software has been developed by OpenLink Software with Kingsley Uyi Idehen and Orri Erling as the chief software architects. Database structure Core database engine Virtuoso provides an extended object–relational model, which combines the flexibility of relational access with inheritance, run time data typing, late binding, and identity-based access.

EDA Database
An EDA database is a database specialized for the purpose of electronic design automation. These application specific databases are required because general purpose databases have historically not provided enough performance for EDA applications. In examining EDA design databases, it is useful to look at EDA tool architecture, to determine which parts are to be considered part of the design database, and which parts are the application levels. In addition to the database itself, many other components are needed for a useful EDA application. Associated with a database are one or more language systems (which, although not directly part of the database, are used by EDA applications such as '' parameterized cells'' and user scripts). On top of the database are built the algorithmic engines within the tool (such as timing, placement, routing, or simulation engines ), and the highest level represents the applications built from these component blocks, such as floorplanning. The sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenAccess
OpenAccess is a proprietary API controlled by the OpenAccess Coalition that aims to facilitate Interoperability of electronic design automation software among the members of that coalition. OpenAccess Coalition OpenAccess Coalition is a coalition amongst integrated circuit manufacturers to provide a standard for designing integrated circuit chips. The OpenAccess Coalition is an organization of semiconductor industry companies claiming to be competition-neutral that are leading this effort operating under Silicon Integration Initiative bylaws. In 2005 the Cadence Berkeley Labs and the Silicon Integration Initiative launched the OpenAccesGear, a project to develop open source utilities on top of the OpenAccess database. Participants included University of California at Berkeley, UCLA The University of California, Los Angeles (UCLA) is a public university, public Land-grant university, land-grant research university in Los Angeles, California.

Terminology-oriented Database
A terminology-oriented database or terminology-oriented database management system is a conceptual extension of an object-oriented database. It implements concepts defined in a terminology model. Compared with object-oriented databases, the terminology-oriented database requires some minor conceptual extensions on the schema level as supporting set relations (super-set, subset, intersection etc.), weak-typed collections or shared inheritance. The data model of a terminology-oriented database is high-level; the terminology-oriented database provides facilities for transforming a terminology model provided by subject area experts completely into a database schema. The target schema might be the database schema for an object-oriented database as well as a relational database schema, or even an XML schema. Typically, terminology-oriented databases are not bound on a specific database type. Since the information content, which can be stored in object-oriented databases and in rela ...

GNU GPL
The GNU General Public License (GNU GPL or simply GPL) is a series of widely used free software licenses that guarantee end users the four freedoms to run, study, share, and modify the software. The license was the first copyleft for general use and was originally written by the founder of the Free Software Foundation (FSF), Richard Stallman, for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. These GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. It is more restrictive than the Lesser General Public License and even further distinct from the more widely used permissive software licenses BSD, MIT, and Apache. Historically, the GPL license family has been one of the most popular software licenses in the free and open-source software domain. Prominent free software programs licensed under the GPL include the Linux ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Objectstore
ObjectStore is a commercial object database, a specialized type of NoSQL database designed to handle data created by applications that use object-oriented programming techniques, avoiding the Object to Relational Mapping overhead required when using object-oriented data with a Relational Database. It is inspired by the Statice database originally developed at Symbolics. ObjectStore is innovative in its use of the C++ language to make database access transparent. Objects can be created in a database by overloading the operator new(). In this way, one can create new C++ objects directly in the database yet these persistent objects look and behave just like normal C++ objects. Data is mapped into memory as operating system pages. When data is referenced in a different page, by making use of signals, ObjectStore traps the pointer exception and transparently brings objects in from the database by bringing in the required page(s). In addition, by use of a technique called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Python (programming Language)
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is dynamically-typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language and first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000 and introduced new features such as list comprehensions, cycle-detecting garbage collection, reference counting, and Unicode support. Python 3.0, released in 2008, was a major revision that is not completely backward-compatible with earlier versions. Python 2 was discontinued with version 2.7.18 in 2020. Python consistently ran ...

Objectivity/DB
Objectivity/DB is a commercial object database produced by Objectivity, Inc. It allows applications to make standard C++, C#, Java, or Python objects persistent without having to convert the data objects into the rows and columns used by a relational database management system (RDBMS). Objectivity/DB supports the most popular object oriented languages plus SQL/ODBC and XML. It runs on Linux, Macintosh, UNIX and Windows platforms. All of the languages and platforms interoperate, with the Objectivity/DB kernel taking care of compiler and hardware platform differences. History Objectivity/DB was first sold in 1990. The C++ and Java interfaces for Objectivity/DB incorporate the features defined in the ODMG'93 standard. The C# and Python interfaces were added subsequently. Architectural features Objectivity/DB is a distributed database that provides a single logical view across a federation of databases distributed across the network. It uses a distributed computing model ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
