Data Governance Manager

Data governance controls the management of the data lifecycle to ensure that quality data is available in a controlled, secure and timely fashion. Data governance helps ensure regulatory compliance, risk management and the establishment of data lineage.

In a Big Data environment, the variety characteristic coupled with unknown access scenarios can make data governance a challenging task. A data governance manager provides the means for performing various data governance tasks in a centralized manner (Figure 1).

A data governance manager provides information on:

  • serialization engine
  • compression engine
  • where the dataset resides
  • who the data owner/steward is
  • what the format of the data is
  • when the dataset was acquired
  • the source of the dataset
  • expiry date (if any)
  • schema information via metadata search
  • a lineage viewer for establishing provenance

In essence, a data governance manager supports data lifecycle management through:

  • the authoring of data retention and eviction policies
  • the establishment of security policies that specify the conditions under which encryption is applied to a dataset or specific fields of a dataset
  • the creation of policies that establish disaster recovery management procedures

Furthermore, a data governance manager can provide information on the level of trust and sensitivity of data. This information includes whether or not the data can be stored in a cloud environment, as well as any geographical limitations for data persistence.

To ensure enhanced data confidentiality and privacy within a cluster, an advanced data governance manager may further enable fine-grained control over data storage by specifying which nodes can store which types of datasets.

Data Governance Manager: Figure 1 - A database administrator needs to attach a data retention policy to a dataset. A data governance manager can be used to author the retention policy, which is then attached to the relevant dataset.
