In this section, we will understand the characteristic features of enterprise data. Each
of the listed characteristics describes a unique facet/behavior that would be elabor-
ated in the implementation perspective later in the Data Science life cycle section in
this chapter. Following are a few important characteristics of enterprise data:
Included :Enterprisedataisintegratedandusually,butnotmandatorily,cent-
ralized to all applications within an enterprise. Data from various sources and
varied formats is either aggregated or federated for this purpose. (Aggrega-
tion refers to physically combining data sets into a single structure and loca-
tion while federation is all about getting a centralized way to access a variety
of data sources to get the required data without physically combining/mer-
ging the data.)
Standards compliance : Data is represented/presented to the application in
context in a format that is either a standard to an enterprise/across enter-
Secure : Data is securely accessible through authorization.
Scalable : In a context where data is integrated from various sources, the
need to support larger volumes becomes critical, and thus the scalability,
both in terms of storage and processing.
Condensed/Cleansed/Consistent : Enterprise data can possibly be con-
densed and cleansed to ensure data quality against a given set of data
standards for an enterprise.
Varied sources and formats : Data is mostly combined from varied sources
and can continue to be stored in varied formats for optimized usage.
