Database Design and Management
This is the process of producing a detailed data model of a database, including tables, fields, and relationships.
What is database design?
These are overarching principles that outline an organization’s approach to specific issues, connecting vision, values, and operations.
What are policies?
This data model represents geographic features as points, lines, and polygons.
What is the vector data model?
This variable in symbolization refers to the shade of color, such as dark red or light red, and is used for quantitative data.
What is value?
This type of map has no elevation data.
What is a planimetric map?
This database object improves query performance by allowing faster data retrieval based on indexed columns.
What is an index?
These provide specific action plans for implementing policies and guide employees on how to handle various situations.
What are procedures?
This type of data is composed of a grid of cells, each with a value representing a specific attribute.
What is raster data?
This process involves using more than two sets of data on one map, such as showing population density and rainfall together.
What is multivariate display?
These are the four kinds of distortion introduced by projected coordinate systems.
What are area, shape, distance, and direction?
The full form of RDBMS is this.
What is Relational Database Management System?
This term refers to individuals, groups, or entities that have an interest, participation, or role in a project or program.
What are stakeholders?
The smallest resolvable piece of a scanned image in GIS is called this.
What is a pixel?
This symbol type is drawn proportional in size to the value being represented.
What is a proportional symbol?
A meridian is a line of this geographic measurement.
What is longitude?
This enforces data integrity by defining a set of permissible values for an attribute in a geodatabase.
What is a domain?
This systematic approach ensures the availability, quality, security, and proper utilization of an organization’s data.
What is data governance?
This database structure stores related information in a tree-like format, allowing records to be traced to parent records.
What is a hierarchical database?
Lines of equal value, such as contour lines, are used in this mapping technique.
What is isarithmic or isopleth mapping?
The equator is this many kilometers longer than the prime meridian.
What is 67 kilometers?
This type of procedural code is automatically executed in response to certain events on a particular table or view in a database.
What is a trigger?
This is the longest path through a project or to a defined milestone, made up of related linked tasks.
What is the critical path?
This calculation describes the difference between a measurement and its true value, often used in georectification.
What is Root Mean Squared Error (RMS)?
This mapping technique uses ancillary information to model the internal distribution of a phenomenon, as an alternative to choropleth mapping.
What is dasymetric mapping?
When georeferencing, this transformation preserves the shape of the original raster, allowing rotation and scaling but keeping straight lines straight.
What is a similarity transformation?
