[4]: 114 A DataFrame is a 2-dimensional data structure of rows and columns, similar to a spreadsheet, and analogous to a Python dictionary mapping column names (keys) to Series (values), with each Series sharing an index. [4]: 115 DataFrames can be concatenated together or "merged" on columns or indices in a manner similar to joins in SQL.
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").

Tabular data is two dimensional in nature - data is represented in rows and columns. However, modern operating systems logically represent data in a linear memory model , both in-disk and in-memory. [ 7 ] [ 8 ] [ 9 ] Therefore, a table in a linear memory model requires projecting its two-dimensional items in a one-dimensional space.
