Back End (computing)
In software engineering, the terms frontend and backend (or sometimes referred to as back end or back-end) refer to the separation of concerns between the presentation layer (''frontend''), and the data access layer (''backend'') of a piece of software, or the physical infrastructure or hardware. In the client–server model, the client is usually considered the frontend and the server is usually considered the backend, even when some presentation work is actually done on the server itself. Introduction In software architecture, there may be many layers between the hardware and end user. The ''front'' is an abstraction, simplifying the underlying component by providing a user-friendly interface, while the ''back'' usually handles data storage and business logic. In telecommunication, the ''front'' can be considered a device or service, while the ''back'' is the infrastructure that supports provision of service. A rule of thumb is that the client-side (or "frontend") ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Back-end CASE
Computer-aided software engineering (CASE) is the domain of software tools used to design and implement applications. CASE tools are similar to and were partly inspired by Computer-Aided Design (CAD) tools used for designing hardware products. CASE tools were used for developing high-quality, defect-free, and maintainable software. CASE software is often associated with methods for the development of information systems together with automated tools that can be used in the software development process. History The Information System Design and Optimization System (ISDOS) project, started in 1968 at the University of Michigan, initiated a great deal of interest in the whole concept of using computer systems to help analysts in the very difficult process of analysing requirements and developing systems. Several papers by Daniel Teichroew fired a whole generation of enthusiasts with the potential of automated systems development. His Problem Statement Language / Problem Statement An ...

Back-end Database
{{No footnotes, date=December 2021 A back-end database is a database that is accessed by users indirectly through an external application rather than by application programming stored within the database itself or by low level manipulation of the data (e.g. through SQL commands). A back-end database stores data but does not include end-user application elements such as stored queries, forms, macros or reports. The back-end database concept was invented by Microsoft Microsoft Corporation is an American multinational technology corporation producing computer software, consumer electronics, personal computers, and related services headquartered at the Microsoft Redmond campus located in Redmond, Washing ... in 1989. Enterprise database systems The term back-end database is not widely used among developers using larger or enterprise database systems. This is because enterprise database systems enforce the use of the client–server model and do not have the option to in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Back-end Processor
A database machines or back end processor is a computer or special Computer hardware, hardware that stores and retrieves data from a database. It is specially designed for database access and is tightly coupled to the main (Front and back ends, front-end) computer(s) by a high-speed channel, whereas a database server is a general-purpose computer that holds a database and it's loosely coupled via a local area network to its Client (computing), clients. Database machines can retrieve large amount of data using Parallel computing, hundreds to thousands of microprocessor, microprocessors with DBMS, database software. The front end processor asks the back end (typically sending a query expressed in a query language) the data and further processes it. The back end processor on the other hand analyzes and stores the data from the front end processor. Back end processors result in higher performance, increasing host Computer memory, main memory, increasing Data recovery, database recovery a ...

Back-end Design
In integrated circuit design, physical design is a step in the standard design cycle which follows after the circuit design. At this step, circuit representations of the components (devices and interconnects) of the design are converted into geometric representations of shapes which, when manufactured in the corresponding layers of materials, will ensure the required functioning of the components. This geometric representation is called integrated circuit layout. This step is usually split into several sub-steps, which include both design and verification and validation of the layout. Modern day Integrated Circuit (IC) design is split up into ''Front-end Design using HDLs'' and ''Back-end Design'' or ''Physical Design''. The inputs to physical design are (i) a netlist, (ii) library information on the basic devices in the design, and (iii) a technology file containing the manufacturing constraints. Physical design is usually concluded by ''Layout Post Processing'', in which amendm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Back End Of Line
The back end of line (BEOL) is the second portion of IC fabrication where the individual devices (transistors, capacitors, resistors, etc.) get interconnected with wiring on the wafer, the metalization layer. Common metals are copper and aluminum. BEOL generally begins when the first layer of metal is deposited on the wafer. BEOL includes contacts, insulating layers (dielectrics), metal levels, and bonding sites for chip-to-package connections. After the last FEOL step, there is a wafer with isolated transistors (without any wires). In BEOL part of fabrication stage contacts (pads), interconnect wires, vias and dielectric structures are formed. For modern IC process, more than 10 metal layers can be added in the BEOL. Steps of the BEOL: # Silicidation of source and drain regions and the polysilicon region. # Adding a dielectric (first, lower layer is pre-metal dielectric (PMD) – to isolate metal from silicon and polysilicon), CMP processing it # Make holes in PMD, make a ...

Autumn
Autumn, also known as fall in American English and Canadian English, is one of the four temperate seasons on Earth. Outside the tropics, autumn marks the transition from summer to winter, in September ( Northern Hemisphere) or March ( Southern Hemisphere). Autumn is the season when the duration of daylight becomes noticeably shorter and the temperature cools considerably. Day length decreases and night length increases as the season progresses until the Winter Solstice in December (Northern Hemisphere) and June (Southern Hemisphere). One of its main features in temperate climates is the striking change in colour for the leaves of deciduous trees as they prepare to shed. Date definitions Some cultures regard the autumnal equinox as "mid-autumn", while others with a longer temperature lag treat the equinox as the start of autumn. In the English-speaking world of high latitude countries, autumn traditionally began with Lammas Day and ended around Hallowe'en, the approxima ...

Back End Load
Mutual fund fees and expenses are charges that may be incurred by investors who hold mutual funds. Operating a mutual fund involves costs, including shareholder transaction costs, investment advisory fees, and marketing and distribution expenses. Funds pass along these costs to investors in several ways. Some funds impose "shareholder fees" directly on investors whenever they buy or sell shares. In addition, every fund has regular, recurring, fund-wide "operating expenses". Funds typically pay their operating expenses out of fund assets—which means that investors indirectly pay these costs. Although they may seem negligible, fees and expenses can substantially reduce an investor's earnings when the investment is held for a long period of time. For the reasons cited above, it is important for a prospective investor to compare the fees of the various funds under consideration. Investors should also compare fees against industry benchmarks and averages. There are many different ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Buttocks
The buttocks (singular: buttock) are two rounded portions of the exterior anatomy of most mammals, located on the posterior of the pelvic region. In humans, the buttocks are located between the lower back and the perineum. They are composed of a layer of exterior skin and underlying subcutaneous fat superimposed on a left and right gluteus maximus and gluteus medius muscles. The two gluteus maximus muscles are the largest muscles in the human body. They are responsible for movements such as straightening the body into the upright (standing) posture when it is bent at the waist; maintaining the body in the upright posture by keeping the hip joints extended; and propelling the body forward via further leg (hip) extension when walking or running. In the seated position, the buttocks bear the weight of the upper body and take that weight off the feet. In many cultures, the buttocks play a role in sexual attraction. Many cultures have also used the buttocks as a primary target f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
