Recursion in data structure is a process where a function calls itself directly or indirectly to solve a problem, breaking it into smaller instances of itself.
When advancing through the data lifecycle stages, data may change their model/structure and consequently metadata; this may also be a consequence of using different systems or platforms at different data processing stages. Linking data during the whole data lifecycle is a significant problem in Big ...

Another Scala lib for data visualization is Vegas. It is much more functional than Breeze-viz and allows to make some plotting specifications such as filtering, transformations, and aggregations. It is similar in structure to Python’s Bokeh and Plotly. ...

“ top-down style of management that organizations have tried to impose on data lakes has been a failure. The data mesh tries to re-imagine that ownership structure in a bottoms-up manner” Data Fabric是与WareHouse、DataLake、LakeHouse等技术类似的概念,可以认为是第X代的DataPlatform,一种新的...
In this example we defined the variable a to have the type Double, a double-precision floating-point number. And then, because it is a variable, we reassigned it to a different value. This has been a short introduction to using values, variables, types, and literals in Scala. In the re...
