Power Query is built on what was then [when?] a new query language called M.It is a mashup language (hence the letter M) designed to create queries that mix together data. It is similar to the F Sharp programming language, and according to Microsoft it is a "mostly pure, higher-order, dynamically typed, partially lazy, functional language."
Once processed and organized, the data may be incomplete, contain duplicates, or contain errors. [21] [22] The need for data cleaning will arise from problems in the way that the datum are entered and stored. [21] Data cleaning is the process of preventing and correcting these errors.
In computing, data deduplication is a technique for eliminating duplicate copies of repeating data. Successful implementation of the technique can improve storage utilization, which may in turn lower capital expenditure by reducing the overall amount of storage media required to meet storage capacity needs.
powercfg (executable name powercfg.exe) is a command-line utility that is used from an elevated Windows Command Prompt to control all configurable power system settings, including hardware-specific configurations that are not configurable through the Control Panel, on a per-user basis.
LINQ by Microsoft provides a query language for the .NET Framework that is heavily influenced by functional programming concepts, including core operators for composing queries monadically. [ 16 ] ZipperFS is a simple, experimental file system that also uses the zipper structure primarily to implement its features.

The Z-ordering can be used to efficiently build a quadtree (2D) or octree (3D) for a set of points. [4] [5] The basic idea is to sort the input set according to Z-order.Once sorted, the points can either be stored in a binary search tree and used directly, which is called a linear quadtree, [6] or they can be used to build a pointer based quadtree.
Human-friendly forum URLs do not have a query string and instead contain only the path of the topic. A user- un friendly URL may contain cryptic parameters, numeric IDs, or file type extensions (e.g. .php ) that do not matter to the user and could change if the forum is reimplemented using a different programming language.
