Pervasive PSQL
Actian Zen (named Pervasive PSQL before version 13) is an ACID-compliant database management system (DBMS) developed by Pervasive Software. It is optimized for embedding in applications and used in several different types of packaged software applications offered by independent software vendors (ISVs) and original equipment manufacturers (OEMs). It is available for software as a service (SaaS) deployment due to a file-based architecture enabling partitioning of data for multitenancy needs. Applications can store the data and the relationships in tables in a relational model (RDBMS) or store the data in a schema-less way with no fixed data model ( key-value store). Pervasive PSQL runs on system platforms that include Microsoft Windows, Linux, and Mac OS X. Both 32-bit and 64-bit editions of Pervasive PSQL are available. Editions are also specifically designed for different computer networking deployment needs, such as workgroup, client-server, and highly virtualized environments, ...

Data Model
A data model is an abstract model that organizes elements of data and standardizes how they relate to one another and to the properties of real-world entities. For instance, a data model may specify that the data element representing a car be composed of a number of other elements which, in turn, represent the color and size of the car and define its owner. The term data model can refer to two distinct but closely related concepts. Sometimes it refers to an abstract formalization of the objects and relationships found in a particular application domain: for example the customers, products, and orders found in a manufacturing organization. At other times it refers to the set of concepts used in defining such formalizations: for example concepts such as entities, attributes, relations, or tables. So the "data model" of a banking application may be defined using the entity-relationship "data model". This article uses the term in both senses. A data model explicitly determines the ...

Small And Medium Enterprises
Small and medium-sized enterprises (SMEs) or small and medium-sized businesses (SMBs) are businesses whose personnel and revenue numbers fall below certain limits. The abbreviation "SME" is used by international organizations such as the World Bank, the European Union, the United Nations, and the World Trade Organization (WTO). In any given national economy, SMEs sometimes outnumber large companies by a wide margin and also employ many more people. For example, Australian SMEs makeup 98% of all Australian businesses, produce one-third of the total GDP (gross domestic product) and employ 4.7 million people. In Chile, in the commercial year 2014, 98.5% of the firms were classified as SMEs. In Tunisia, the self-employed workers alone account for about 28% of the total non-farm employment, and firms with fewer than 100 employees account for about 62% of total employment. The United States' SMEs generate half of all U.S. jobs, but only 40% of GDP. Developing countries tend to have a lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Architecture Of Btrieve
Btrieve is a database developed by Pervasive Software. The architecture of Btrieve has been designed with record management in mind. This means that Btrieve only deals with the underlying record creation, data retrieval, record updating and data deletion primitives. Together with the MicroKernel Database Engine it uses ISAM, Indexed Sequential Access Method, as its underlying storage mechanism. Btrieve is essentially a database that uses keys and indexes to organise data. However, the file structure itself is largely built around smaller units of data, called "pages" in Btrieve. Though the structure has changed over the various versions of Btrieve, the file structure still revolves around a File Control Record (FCR) — which defines the configuration of pages — and pages in the Btrieve file that contain data. Historically, Btrieve used "physical pages", or pages that were located at fixed positions in the file. Beginning with version 6.0 "logical pages" started to be used, whi ...

Cloud Computing
Cloud computing is the on-demand availability of computer system resources, especially data storage ( cloud storage) and computing power, without direct active management by the user. Large clouds often have functions distributed over multiple locations, each of which is a data center. Cloud computing relies on sharing of resources to achieve coherence and typically uses a "pay as you go" model, which can help in reducing capital expenses but may also lead to unexpected operating expenses for users. Value proposition Advocates of public and hybrid clouds claim that cloud computing allows companies to avoid or minimize up-front IT infrastructure costs. Proponents also claim that cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and that it enables IT teams to more rapidly adjust resources to meet fluctuating and unpredictable demand, providing burst computing capability: high computing p ...

Workgroup (computer Networking)
In computer networking a work group is collection of computers connected on a LAN that share the common resources and responsibilities. Workgroup is Microsoft's term for a peer-to-peer local area network. Computers running Microsoft operating systems in the same work group may share files, printers, or Internet connection. Work group contrasts with a domain, in which computers rely on centralized authentication. See also * Windows for Workgroups – the earliest version of Windows to allow a work group * Windows HomeGroup – a feature introduced in Windows 7 and later removed in Windows 10 (Version 1803) that allows work groups to share contents more easily * Browser service – the service enabled 'browsing' all the resources in work groups * Peer Name Resolution Protocol Peer Name Resolution Protocol (PNRP) is a peer-to-peer protocol designed by Microsoft. PNRP enables dynamic name publication and resolution, and requires IPv6. PNRP was first mentioned during a presentation at ...

Software Deployment
Software deployment is all of the activities that make a software system available for use. The general deployment process consists of several interrelated activities with possible transitions between them. These activities can occur on the Software developer, producer side or on the User (computing), consumer side or both. Because every software system is unique, the precise Process (computing), processes or Algorithm, procedures within each activity can hardly be defined. Therefore, "deployment" should be interpreted as a ''general process'' that has to be customized according to specific requirements or characteristics. History When computers were extremely large, expensive, and bulky (mainframe computer, mainframes and minicomputers), the software was often bundled together with the hardware by manufacturers. If business software needed to be installed on an existing computer, this might require an expensive, time-consuming visit by a systems architect or a consultant. ...

64-bit
In computer architecture, 64-bit Integer (computer science), integers, memory addresses, or other Data (computing), data units are those that are 64 bits wide. Also, 64-bit central processing unit, CPUs and arithmetic logic unit, ALUs are those that are based on processor registers, address buses, or Bus (computing), data buses of that size. A computer that uses such a processor is a 64-bit computer. From the software perspective, 64-bit computing means the use of machine code with 64-bit virtual memory addresses. However, not all 64-bit instruction sets support full 64-bit virtual memory addresses; x86-64 and ARMv8, for example, support only 48 bits of virtual address, with the remaining 16 bits of the virtual address required to be all 0's or all 1's, and several 64-bit instruction sets support fewer than 64 bits of physical memory address. The term ''64-bit'' also describes a generation of computers in which 64-bit processors are the norm. 64 bits is a Word (computer archit ...

32-bit
In computer architecture, 32-bit computing refers to computer systems with a processor, memory, and other major system components that operate on data in 32-bit units. Compared to smaller bit widths, 32-bit computers can perform large calculations more efficiently and process more data per clock cycle. Typical 32-bit personal computers also have a 32-bit address bus, permitting up to 4 GB of RAM to be accessed; far more than previous generations of system architecture allowed. 32-bit designs have been used since the earliest days of electronic computing, in experimental systems and then in large mainframe and minicomputer systems. The first hybrid 16/32-bit microprocessor, the Motorola 68000, was introduced in the late 1970s and used in systems such as the original Apple Macintosh. Fully 32-bit microprocessors such as the Motorola 68020 and Intel 80386 were launched in the early to mid 1980s and became dominant by the early 1990s. This generation of personal computers coincided ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mac OS X
macOS (; previously OS X and originally Mac OS X) is a Unix operating system developed and marketed by Apple Inc. since 2001. It is the primary operating system for Apple's Mac (computer), Mac computers. Within the market of desktop and laptop computers it is the Usage share of operating systems#Desktop and laptop computers, second most widely used desktop OS, after Microsoft Windows and ahead of ChromeOS. macOS succeeded the classic Mac OS, a Mac operating system with nine releases from 1984 to 1999. During this time, Apple cofounder Steve Jobs had left Apple and started another company, NeXT Computer, NeXT, developing the NeXTSTEP platform that would later be acquired by Apple to form the basis of macOS. The first desktop version, Mac OS X 10.0, was released in March 2001, with its first update, 10.1, arriving later that year. All releases from Mac OS X Leopard, Mac OS X 10.5 Leopard and after are UNIX 03 certified, with an exception for OS X Lion, OS X 10. ...
