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

Views

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

OCI Database with PostgreSQL Views
NameDescription
POSTGRESQL_BACKUP_DIM_V This view stores information on database system backups.
POSTGRESQL_CONFIGURATION_DIM_V This view stores information on PostgreSQL configurations for database systems.
POSTGRESQL_DB_INSTANCE_DIM_V This view stores information on database instance nodes.
POSTGRESQL_DB_SYSTEM_DIM_V This view stores information on database systems.
POSTGRESQL_DEFAULT_CONFIGURATION_DIM_V This view stores information on default configurations for PostgreSQL database systems.
POSTGRESQL_BACKUP_FACT_V Fact table for PostgreSQL database backups.
POSTGRESQL_DB_INSTANCE_FACT_V Fact table for PostgreSQL database instances.
POSTGRESQL_DB_SYSTEM_FACT_V Fact table for PostgreSQL database systems.

The suffixes in the view names specify the view type:

  • FACT_V: Fact
  • DIM_V: Dimension

Relationship Diagram

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

The contents of each view and their relationships are listed in the following file: OCI Database with PostgreSQL views.

These diagrams show the relationship of the OCI Database with PostgreSQL fact views with different dimension views.

POSTGRESQL_BACKUP_FACT_V
Relationship diagram showing the fact table, POSTGRESQL_BACKUP_FACT_V.

POSTGRESQL_DB_INSTANCE_FACT_V
Relationship diagram showing the fact table, POSTGRESQL_DB_INSTANCE_FACT_V.

POSTGRESQL_DB_SYSTEM_FACT_V
Relationship diagram showing the fact table, POSTGRESQL_DB_SYSTEM_FACT_V.

Relationships exist among dimensions. Dimensions can be joined directly to each other. These diagrams show the relationship between dimension views.

POSTGRESQL_CONFIGURATION_DIM_V
Relationship diagram showing the dimension table, POSTGRESQL_CONFIGURATION_DIM_V.

POSTGRESQL_DEFAULT_CONFIGURATION_DIM_V
Relationship diagram showing the dimension table, POSTGRESQL_DEFAULT_CONFIGURATION_DIM_V.

Subject Areas

This section provides information on the subject areas with data you maintain in OCI Database with PostgreSQL. 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:
