Which is NOT a valid Geometry Column Data Type available for maps region?

A. Latitude/Longitude
B. JSON_OBJECT
C. SDO_GEOMETRY
D. GeoJSON

Answer: B

Explanation:
Explanation
The valid Geometry Column Data Types for maps region are Latitude/Longitude, GeoJSON, and SDO_GEOMETRY. These types represent different ways of storing spatial data in Oracle Database.
Latitude/Longitude uses two numeric columns for longitude and latitude values. GeoJSON uses a VARCHAR2 or CLOB column that contains geometry information in GeoJSON format. SDO_GEOMETRY uses an object type that stores spatial data using Oracle Spatial features. JSON_OBJECT is not a valid Geometry Column Data Type for maps region.

NEW QUESTION # 43
Which search type in Search Configurations provides linguistic and fuzzy search capabilities?

A. List
B. Oracle Text
C. Standard

Answer: B

Explanation:
Explanation
Search Configurations is a feature that allows developers to define how end users can search for data in an application. There are three types of search configurations: Standard, List, and Oracle Text. Oracle Text is a search type that provides linguistic and fuzzy search capabilities by using an Oracle Text index on a table column or view column. Linguistic search enables end users to search for data based on language-specific rules and preferences, such as stemming, stopwords, synonyms, etc. Fuzzy search enables end users to search for data based on approximate matches that account for spelling errors, typos, OCR errors, etc. Verified References: [Managing Search Configurations - Oracle Help Center], [Oracle Text User's Guide]

You can create automation tasks by using the Database Actions interface or by using the APEX_AUTOMATION package. To log messages to the execution log in APEX automation, you can use the APEX_DEBUG package with any of its logging levels (info, warning, error, etc.).

NEW QUESTION # 45
Choose the three supported spatial geometry objects in Maps.

A. Bars
B. Points
C. Heat map
D. Polygons

Answer: B,C,D

Explanation:
Explanation
A map is a type of component that enables users to view and manage data based on geographic locations. A map consists of a background map and spatial geometry objects that are sourced from data in a table or from a REST data source. Spatial geometry objects are shapes that represent real-world features on a map, such as points, lines, polygons, or heat maps. Three of the supported spatial geometry objects in Oracle APEX are:
Polygons: A polygon is a closed shape that consists of three or more vertices connected by straight line segments. A polygon can represent an area on a map, such as a country, a state, a city, or a building. A polygon can have different colors, patterns, or borders to indicate different attributes or categories of the data.
Heat map: A heat map is a type of visualization that uses color gradients to show the density or intensity of data values in a geographic area. A heat map can represent the distribution or variation of a numeric variable on a map, such as population, income, crime rate, or temperature.
Points: A point is a zero-dimensional shape that represents a single location on a map. A point can have different symbols, sizes, or colors to indicate different attributes or categories of the data. A point can also have a label or a tooltip to display additional information about the data.
