Business Directory (Yellow Pages) Support

13 Business Directory (Yellow Pages) Support

Oracle Spatial and Graph provides support for OpenLS business directory (Yellow Pages, or YP) services.

Note:

Oracle Spatial and Graph business directory services are not supported in Oracle Autonomous Database in both shared and dedicated deployments.

Business Directory Concepts
Business directory services provide lists of businesses in a given area and matching a specified name or category.
Using the Business Directory Capabilities
To use the Oracle Spatial business directory capabilities, you must use data provided by a business directory (YP) vendor.
Data Structures for Business Directory Support
After you acquire the business directory data and invoke the appropriate procedure to load it into the database, the procedure populates the following tables, all owned by the MDSYS schema, which are used for business directory support.

13.1 Business Directory Concepts

Business directory services provide lists of businesses in a given area and matching a specified name or category.

Business directory data comes from third-party providers of such data. These providers probably have different business categories, and even different hierarchical structures. A unifying pattern in the various approaches is that businesses are categorized by subject and location. The location component is well understood; for example, for the United States, either a ZIP code or the combination of a city and state, and optionally a specific address, can be used to determine the location from which to start searching.

The categorization of businesses, on the other hand, is not uniformly implemented. Some providers offer a flat list of categories, user-selected by simple substring matching. Others offer a 3-level or 4-level hierarchical organization of subcategories, often with a fanout (maximum number of child categories at a level) of 20 to 50, and sometimes more than 100. A user might start the hierarchy traversal at the root of the hierarchy (by default). Alternatively, a user might enter a keyword that is matched to an appropriate starting point within the hierarchy. Such keyword matching might go beyond simple substring matching and result in more intelligent choices.

13.2 Using the Business Directory Capabilities

To use the Oracle Spatial business directory capabilities, you must use data provided by a business directory (YP) vendor.

The data must be in the format supported by the Oracle Spatial and Graph OpenLS support (see OPENLS_DIR_BUSINESSES Table).

To submit users' directory services requests and to return the responses, use the OpenLS web services API, which is introduced in OpenLS Application Programming Interfaces. For information about directory services requests and responses, with examples, see OpenLS Service Support and Examples.

13.3 Data Structures for Business Directory Support

After you acquire the business directory data and invoke the appropriate procedure to load it into the database, the procedure populates the following tables, all owned by the MDSYS schema, which are used for business directory support.

OPENLS_DIR_BUSINESSES
OPENLS_DIR_BUSINESS_CHAINS
OPENLS_DIR_CATEGORIES
OPENLS_DIR_CATEGORIZATIONS
OPENLS_DIR_CATEGORY_TYPES
OPENLS_DIR_SYNONYMS

In some tables, some rows have null values for some columns, because the information does not apply in this instance or because the data provider did not supply a value.

The following sections describe these tables, in alphabetical order by table name.

13.3.1 OPENLS_DIR_BUSINESSES Table

The OPENLS_DIR_BUSINESSES table stores information about each business (that is, each business that has an address). If the business is part of a larger business chain, the CHAIN_ID column is a foreign key to the CHAIN_ID column in the OPENLS_DIR_BUSINESS_CHAINS table (described in OPENLS_DIR_BUSINESS_CHAINS Table).

The OPENLS_DIR_BUSINESSES table contains one row for each business, and it contains the columns shown in Table 13-1.

Table 13-1 OPENLS_DIR_BUSINESSES Table

Column Name	Data Type	Description
BUSINESS_ID	NUMBER	Business ID number. (Required)
BUSINESS_NAME	VARCHAR2(128)	Area name. (Required)

13.3.2 OPENLS_DIR_BUSINESS_CHAINS Table

The OPENLS_DIR_BUSINESS_CHAINS table stores information about each business chain. A business chain is a business that has multiple associated businesses; for example, a restaurant chain has multiple restaurants that have the same name and offer basically the same menu. If the business is part of a business chain, the row for that business in the OPENLS_DIR_BUSINESSES table (described in OPENLS_DIR_BUSINESSES Table) contains a CHAIN_ID column value that matches a value in the CHAIN_ID column in the OPENLS_DIR_BUSINESS_CHAINS table.

The OPENLS_DIR_BUSINESS_CHAINS table contains one row for each business chain, and it contains the columns shown in Table 13-2.

Table 13-2 OPENLS_DIR_BUSINESS_CHAINS Table

Column Name	Data Type	Description
CHAIN_ID	NUMBER	Business chain ID number. (Required)
CHAIN_NAME	VARCHAR2(128)	Business chain name.

13.3.3 OPENLS_DIR_CATEGORIES Table

The OPENLS_DIR_CATEGORIES table stores information about each category into which a business can be placed. If the data provider uses a category hierarchy, this table contains rows for categories at all levels of the hierarchy, using the PARENT_ID column to indicate the parent category of a child category. For example, a Restaurants category might be the parent of several child categories, one of which might be Chinese.

The OPENLS_DIR_CATEGORIES table contains one row for each category, and it contains the columns shown in Table 13-3.

Table 13-3 OPENLS_DIR_CATEGORIES Table

Column Name	Data Type	Description
CATEGORY_ID	VARCHAR2(32)	Category ID string. (Required)
CATEGORY_TYPE_ID	NUMBER	Category type ID number. Must match a value in the CATEGORY_TYPE_ID column of the OPENLS_DIR_CATEGORY_TYPES table (described in OPENLS_DIR_CATEGORY_TYPES Table). (Required)
CATEGORY_NAME	VARCHAR2(128)	Category name. (Required)
PARENT_ID	VARCHAR2(32)	CATEGORY_ID value of the parent category, if any, for this category.
PARAMETERS	XMLTYPE	XML document with additional information about the category.

13.3.4 OPENLS_DIR_CATEGORIZATIONS Table

The OPENLS_DIR_CATEGORIZATIONS table stores information about associations of businesses with categories. Each business can be in multiple categories; and the categories for a business can be independent of each other or in a parent-child relationship, or both. For example, a store that sells books and music CDs might be in the categories for Bookstores, Music, and its child category Music Stores, in which case there will be three rows for that business in this table.

The OPENLS_DIR_CATEGORIZATIONS table contains one row for each association of a business with a category, and it contains the columns shown in Table 13-4.

Table 13-4 OPENLS_DIR_CATEGORIZATIONS Table

Column Name	Data Type	Description
BUSINESS_ID	NUMBER	Business ID. Must match a value in the BUSINESS_ID column of the OPENLS_DIR_BUSNESSES table (described in OPENLS_DIR_BUSINESSES Table). (Required)
CATEGORY_ID	VARCHAR2(32)	Category ID string. The CATEGORY_ID and CATEGORY_TYPE_ID values must match corresponding column values in a single row in the OPENLS_DIR_CATEGORIES table (described in OPENLS_DIR_CATEGORIES Table). (Required)
CATEGORY_TYPE_ID	NUMBER	Category type ID number. The CATEGORY_ID and CATEGORY_TYPE_ID values must match corresponding column values in a single row in the OPENLS_DIR_CATEGORIES table (described in OPENLS_DIR_CATEGORIES Table). (Required)
CATEGORIZATION_TYPE	VARCHAR2(8)	`EXPLICIT` (the default) or `IMPLICIT`.

13.3.6 OPENLS_DIR_SYNONYMS Table

The OPENLS_DIR_SYNONYMS table stores information about synonyms for categories. Synonyms can be created to expand the number of terms (strings) associated with a category, so that users get more complete and meaningful results from a search.

The OPENLS_DIR_SYNONYMS table contains one row for each synonym definition, and it contains the columns shown in Table 13-6.

Table 13-6 OPENLS_DIR_SYNONYMS Table
