Entity–attribute–value model. An entity–attribute–value model ( EAV) is a data model optimized for the space-efficient storage of sparse—or ad-hoc —property or data values, intended for situations where runtime usage patterns are arbitrary, subject to user variation, or otherwise unforeseeable using a fixed design.
Major implementations. .NET languages ( C#, F#, VB.NET) Influenced by. SQL, Haskell. Language Integrated Query ( LINQ, pronounced "link") is a Microsoft .NET Framework component that adds native data querying capabilities to .NET languages, originally released as a major part of .NET Framework 3.5 in 2007.
Temporal database. A temporal database stores data relating to time instances. It offers temporal data types and stores information relating to past, present and future time. Temporal databases can be uni-temporal, bi-temporal or tri-temporal. More specifically the temporal aspects usually include valid time, transaction time and/or decision time .
The data rate can range from kilobits per second in case of ABSs-ground users link, so that the 4G frequency bandwidth can be adopted, up to gigabits per second in case of ABS-backhaul network or ABS-ABS communications. Since these latter are mainly dominated by LoS component, the utilization of millimeter-wave bandwidth is a prominent solution ...
List of tz database time zones. The tz database partitions the world into regions where local clocks all show the same time. This map was made by combining version 2023d with OpenStreetMap data, using open source software. [1] This is a list of time zones from release 2024a of the tz database. [2]
A time series database is a software system that is optimized for storing and serving time series through associated pairs of time (s) and value (s). [1] In some fields, time series may be called profiles, curves, traces or trends. [2] Several early time series databases are associated with industrial applications which could efficiently store ...
Agent-based social simulation is a scientific discipline concerned with simulation of social phenomena, using computer-based multiagent models. In these simulations, persons or group of persons are represented by agents. MABSS is a combination of social science, multiagent simulation and computer simulation . ABSS models the different elements ...
The Timekeeper. The Timekeeper (also known as From Time to Time and Un Voyage à Travers le Temps) was a 1992 Circle-Vision 360° film that was presented at three Disney parks around the world. It was the first Circle-Vision show that was arranged and filmed with an actual plot and not just visions of landscapes, and the first to utilize Audio ...
