Property Graph; consisting of a set of objects or vertices, and a set of arrows or edges connecting the objects. Vertices and edges can have multiple properties, which are represented as key–value pairs. Includes PGQL, an SQL-like graph query language and an in-memory analytic engine (PGX) nearly 60 prebuilt parallel graph algorithms ...
Prior work by WG3 and SC32 mirror bodies, particularly in INCITS Data Management (formerly INCITS DM32), has helped to define a new planned Part 16 of the SQL Standard, which allows a read-only graph query to be called inside a SQL SELECT statement, matching a graph pattern using syntax which is very close to Cypher, PGQL and G-CORE, and ...
Overview of a data-modeling context: Data model is based on Data, Data relationship, Data semantic and Data constraint.

Some dimensions are used as filters (for slicing and dicing the data) while others are selected as the axes of a pivot table or pivot chart.
The software is able to plot latitude and longitude coordinates and connect to spatial files [24] like Esri Shapefiles, KML, and GeoJSON to display custom geography. [25] The built-in geo-coding allows for administrative places (country, state/province, county/district), postal codes, US Congressional Districts, US CBSA/MSA, Area Codes, Airports, and European Union statistical areas to be ...

Various plots of the multivariate data set Iris flower data set introduced by Ronald Fisher (1936). [1]A data set (or dataset) is a collection of data.In the case of tabular data, a data set corresponds to one or more database tables, where every column of a table represents a particular variable, and each row corresponds to a given record of the data set in question.
