Scalability is the property of a system to handle a growing amount of work. One definition for software systems specifies that this may be done by adding resources to the system. [ 1] In an economic context, a scalable business model implies that a company can increase sales given increased resources. For example, a package delivery system is ...
Shard (database architecture) A database shard, or simply a shard, is a horizontal partition of data in a database or search engine. Each shard is held on a separate database server instance, to spread load. Some data within a database remains present in all shards, [ a] but some appear only in a single shard. Each shard (or server) acts as the ...
Database scalability has three basic dimensions: amount of data, volume of requests and size of requests. Requests come in many sizes: transactions generally affect small amounts of data, but may approach thousands per second; analytic queries are generally fewer, but may access more data. A related concept is elasticity, the ability of a ...
Atmospheric models calculate winds, heat transfer, radiation, relative humidity, and surface hydrologywithin each grid and evaluate interactions with neighboring points. [1] A general circulation model(GCM) is a type of climate model. It employs a mathematical modelof the general circulation of a planetary atmosphereor ocean.
The model of hierarchical complexity (MHC) is a formal theory and a mathematical psychology framework for scoring how complex a behavior is. [4] Developed by Michael Lamport Commons and colleagues, [3] it quantifies the order of hierarchical complexity of a task based on mathematical principles of how the information is organized, [5] in terms ...
A vertically exaggerated mountain. In reality, the terrain would appear much flatter. Vertical exaggeration ( VE) is a scale that is used in raised-relief maps, plans and technical drawings ( cross section perspectives), in order to emphasize vertical features, which might be too small to identify relative to the horizontal scale. [ 1]
Vertical scaling, also known as scaling up, is the process of replacing a component with a device that is generally more powerful or improved. For example, replacing a processor with a faster one. Horizontal scaling, also known as scaling out is setting up another server for example to run in parallel with the original so they share the workload.
Privilege escalation is the act of exploiting a bug, a design flaw, or a configuration oversight in an operating system or software application to gain elevated access to resources that are normally protected from an application or user. The result is that an application or user with more privileges than intended by the application developer or ...
