Reference for DNS

This guide lists the predefined objects in OCI Resource Analytics for the DNS service. You can find information about views, entity relationships, subject areas, and sample queries.

Views

This section provides information about views within OCI Resource Analytics DNS and their columns, data types, keys, and the referred view and column names. The following views are available:

DNS Views
Name Description
DNS_RESOLVER_DIM_V This view stores information about an OCI DNS resolver. If the resolver has an attached VCN, the VCN attempts to answer queries based on the attached views in priority order.
DNS_STEERING_POLICY_DIM_V This view stores information about a DNS steering policy.
DNS_STEERING_POLICY_ATTACHMENT_DIM_V This view stores information about an attachment between a steering policy and a domain.
DNS_TSIG_KEY_DIM_V This view stores information about a TSIG key.
DNS_VIEW_DIM_V This view stores information about an OCI DNS view.
DNS_ZONE_DIM_V This view stores information about a DNS zone.
DNS_RESOLVER_FACT_V Fact table for DNS resolvers.
DNS_ZONE_FACT_V Fact table for DNS zones.

The suffixes in the view names designate the view type:

  • FACT_V: Fact
  • DIM_V: Dimension

The contents of each view and their relationships are listed in the following file: DNS views.

Each tab in the Excel spreadsheet contains the details of a view.

Relationship Diagram

This section provides diagrams that define the logical relationship of a fact table with different dimension tables.

This diagram shows the relationship of the DNS fact view with different dimension views.

DNS_RESOLVER_FACT_V
Relationship diagram showing the fact table, DNS_RESOLVER_FACT_V.

DNS_ZONE_FACT_V
Relationship diagram showing the fact table, DNS_ZONE_FACT_V.

Relationships exist among dimensions. Dimensions can be joined directly to each other. This diagram shows the relationship between dimension views.

DNS_STEERING_POLICY_ATTACHMENT_DIM_V
Relationship diagram showing the dimension table, DNS_STEERING_POLICY_ATTACHMENT_DIM_V.

DNS_TSIG_KEY_DIM_V
Relationship diagram showing the dimension table, DNS_TSIG_KEY_DIM_V.

Sample Queries

Sample queries for DNS.

List the number of resolvers associated with each attached VCN ID.
SELECT
    ATTACHED_VCN_ID,
    COUNT(RESOLVER_ID) AS RESOLVER_COUNT
FROM OCIRA.DNS_RESOLVER_FACT_V F
GROUP BY ATTACHED_VCN_ID;
List the number of zones associated with each view ID.
SELECT
    VIEW_ID,
    COUNT(ZONE_ID) AS ZONE_COUNT
FROM OCIRA.DNS_ZONE_FACT_V F
GROUP BY VIEW_ID;

Data Lineage

The Customer Experience Semantic Model Lineage spreadsheet and Metric Calculation Logic spreadsheet for DNS provides an end-to-end data lineage summary report for physical and logical relationships in your data.

For more information, see Data Lineage.

Subject Areas

This section provides information on the subject areas with data you maintain in DNS. These subject areas, with their corresponding data, are available for you to use when creating and editing analyses and reports. The information for each subject area includes:

  • Description of the subject area.

  • Business questions that can be answered by data in the subject area, with a link to more detailed information about each business question.

  • Job-specific groups and duty roles that can be used to secure access to the subject area, with a link to more detailed information about each job role and duty role.

  • Primary navigation to the work area that's represented by the subject area.

  • Time reporting considerations in using the subject area, such as whether the subject area reports historical data or only the current data. Historical reporting refers to reporting on historical transactional data in a subject area. With a few exceptions, all dimensional data are current as of the primary transaction dates or system date.

  • The lowest grain of transactional data in a subject area. The lowest transactional data grain decides how data are joined in a report.

  • Special considerations, tips, and things to look out for in using the subject area to create analyses and reports.

The subject area is:
