Data Governance

Data Governance

The key component of an enterprise information management strategy, data governance is the decision-making and an oversight procedure to create and maintain the quality and integrity of an enterprise data.

Data governance Institute state that  “Data Governance is a system of decision rights and accountability for information-related processes, executed according to agreed-upon models which describe who can take what actions with what information, and when, under what circumstances, using what methods.”



Reason for use of data governance

Uncover adulterated data from enterprise which is not just that of hackers but also by staffs and contractors having right of usage to sensitive areas, whilst the necessary safeguards are not sufficient.

Two examples of significant data slip in 2014

One of the largest bank in the state JP Morgan Chase, had a huge data breach which affected 76 million households and about 7 million small businesses. Hackers got hold of personal information of customer names, phone numbers, email addresses and addresses.

The other organisation is the world`s largest home improvement, Home Depot, it was confirmed that whopping 56 million credit and debit cards were affected by a data breach, and also 53 million email addresses.

The Irish media also reported various number of data governance issues in connection with government departments and private companies.

Data Protection Commissioner Annual Report for 2014, reports a record number of data breach notifications in 2014 (2,264).

A thriving data governance system must including the following:

  • Custodians and owners of data assets of an organisation must be clearly stated or define.
  • Responsibilities of the different section of data and the outline of level of responsibilities in relation to Accuracy, accessibility, consistency and completeness must be clearly written.
  • There must be written organisation policy regarding storing, archive, back up of data and protection from possible mishaps.
  • Controls and audit procedures must be put in place to ensure ongoing compliance’s with organisation and government regulations.
  • Rules protecting data access and levels of accessibility by personnel

Data governance is a vital component of any organisation as it addresses data quality and security requirements regardless of where the data is captured, utilized or stored. Its importance is being understood globally as evidenced by Rand worldwide survey in 2013 on data governance, which found that 96% of respondents shows that data governance is very  important within the organisation.

Customer demands, regulatory compliance, competitive pressures and mergers and acquisitions are motivating organizations to improve data quality and access to information. Leading organizations now realize that data governance is critical to their future viability actionable and intelligent data which gives an organisation a competitive advantage.

Database Approach

Organisation needs vital information to be successful in an agile world,this information is needed to gain a competitive advantage against it opponents. different levels in an organisation requires different data information’s.

Types of Database

Organisation choice of database will be totally dependent on the type of business engaged in ,the usage and the swiftly avail abilities of information gathered.


A sales retail organisation such as dealing in products and services will require an up to date information on sale,stocks,payments and supply purchases showing day to day operations.every transactions must be on record correctly and promptly.a database that is built mainly to help a business day to day operation is known as an operational database(on-line transaction processing(OLTP),TRANSACTION OR PRODUCTION DATABASE).

Data Governance Framework

Naturally,analytically databases consist of two key fundamental:a data warehouse and an online analytically processing(OLAP) front end.

Data warehouse

The data warehouse is a technical database which stores data in a configured optimized decision aid.


Try R

“R is a tool for statistics and data modeling. The R programming language is elegant, versatile, and has a highly expressive syntax designed around working with data. R is more than that, though — it also includes extremely powerful graphics capabilities” ( use in the manupulation of data and the presentation to making it compelling.





Fusion Table


1   Importing Data

The Raw Data used for the project was downloaded through the Irish population census 2011,CSO website.

2    Preparing files for analysis with the use of Excel

  •    The raw data from CSO was downloaded in to Excel sheet and filtered.
  •    The original data was inserted into 4 different columns and it was sorted to just 2 columns i.e. province and the total of each of the province     The raw data also contain North and South Tipperary population figures, these two were merge together into one single value for Tipperary and Dublin total number was used
  •        Instead of the areas under Dublin as shown in the raw data.


 3   The sorted data and kml file was then uploaded into fusion table through Google  drive.

 4 Visualizing

  • used the data to create map instantly and then filter for more selective visualizations


 5   used the data to create 2011 counties story in the data acquired

  • Achieved by Application of colors on selected data by making intensity map for the counties by the use of KML polygons.

6   Publish the visualization on



Data Quality and Data Governance

Data Quality examines various stages which must include the following:

  • Accuracy
  • Relevances
