Data cleansing may also involve harmonization (or normalization) of data, which is the process of bringing together data of "varying file formats, naming conventions, and columns", [2] and transforming it into one cohesive data set; a simple example is the expansion of abbreviations ("st, rd, etc." to "street, road, etcetera").
XSLT 2.0: after an abortive attempt to create a version 1.1 in 2001, [10] the XSL working group joined forces with the XQuery working group to create XPath 2.0, [11] with a richer data model and type system based on XML Schema.
Data sanitization involves the secure and permanent erasure of sensitive data from datasets and media to guarantee that no residual data can be recovered even through extensive forensic analysis. [1] Data sanitization has a wide range of applications but is mainly used for clearing out end-of-life electronic devices or for the sharing and use ...
Data type validation is customarily carried out on one or more simple data fields. The simplest kind of data type validation verifies that the individual characters provided through user input are consistent with the expected characters of one or more known primitive data types as defined in a programming language or data storage and retrieval ...
A proper validation process consists of at least two processes. Validation of a backup file is of little or no use unless it compares the backup file's data to the data of the source. Additionally, "validation" is an unknown unless it's known with certainty that the backup file can actually restore the source's data.
Cross-validation, [2] [3] [4] sometimes called rotation estimation [5] [6] [7] or out-of-sample testing, is any of various similar model validation techniques for assessing how the results of a statistical analysis will generalize to an independent data set. Cross-validation includes resampling and sample splitting methods that use different ...
Because change a cell from 0 to 1 needs to erase entire block, not just modify some pages, so modify the data of a block may need a read-erase-write process, and the new data is actually moved to another block. In addition, on a NVM Express Zoned Namespaces SSD, it usually uses flash block size as the zone size.
Sheet masks are a relatively new product that is becoming extremely popular in Asia. Sheet masks consist of a thin cotton or fiber sheet with holes cut out for the eyes and lips and cut to fit the contours of the face, onto which serums and skin treatments are brushed in a thin layer; the sheets may be soaked in the treatment.
