Data quality in just 2 essentials

Data timeliness is a matter of the company's and its employees' work, while data accuracy can be managed by applications and is a matter of the IT field.
As far as data quality is concerned, you must distinguish two essential aspects:

1

data timeliness:

data timeliness:

the objective is to guarantee data compliance in relation to the reality of the facts it represents (e.g. the customers' addresses in a CRM), this necessitates organizational procedures within the company in order to guarantee correctness (role of the data stewart, for example)

2

data accuracy:

data accuracy:

within information systems it aims at guaranteeing that the recorded data respect the rules defined by the « business » and that they are not contradictory. This aspect of quality can be controled by tools. A couple of examples of incoherent or contradictory data: a nonexisting date (31 June or an impossible leap year) or the number of children of a customer which wouldn't be the same number from one database to another (Does Mrs. X have 2 or 3 children?)
