[1] Laravel 2 was released in September 2011, bringing various improvements from the author and community.
Therefore, compilers will attempt to transform the first form into the second; this type of optimization is known as map fusion and is the functional analog of loop fusion. [2] Map functions can be and often are defined in terms of a fold such as foldr, which means one can do a map-fold fusion: foldr f z . map g is equivalent to foldr (f .
MapReduce is a programming model and an associated implementation for processing and generating big data sets with a parallel and distributed algorithm on a cluster. [1] [2] [3]A MapReduce program is composed of a map procedure, which performs filtering and sorting (such as sorting students by first name into queues, one queue for each name), and a reduce method, which performs a summary ...
The program can create a complete text representation of any group of objects by calling these methods, which are almost always already implemented in the base associative array class. [23] For programs that use very large data sets, this sort of individual file storage is not appropriate, and a database management system (DB) is required. Some ...
Data collection system (DCS) is a computer application that facilitates the process of data collection, allowing specific, structured information to be gathered in a systematic fashion, subsequently enabling data analysis to be performed on the information.
For example, many web frameworks provide libraries for database access, templating frameworks, and session management, and they often promote code reuse. [1] Although they often target development of dynamic web sites , they are also applicable to static websites .
There are many practical examples of data whose valid values are restricted within a small range. A trivial hash function is a suitable choice when such data needs to act as a lookup key. Some examples include: month in the year (1–12) day in the month (1–31) day of the week (1–7)
Maps are stored as graphs, or two dimensional arrays of objects with attributes of location and category, where some common categories include parks, roads, cities, and the like. A map database represents a road network along with associated features. Map providers can choose various models of a road network as a basis to formulate a database.
