Hi ,
These are the different types of tables in MDM
Flat Tables : It is a simple table consisting of record and fields ( rows and column) .
Hierarchy Table : A hierarchy table organizes information in a hierarchy, where each record is related to a parent record (even if the only parent is the root) and may also be related to sibling records and/or child records.
Taxonomy Table : A taxonomy is the classification scheme that defines the categories and subcategories that apply to a collection of records. Categorizing records enables you to isolate subsets of records for various organizing, searching, editing and publishing purposes.
Qualified Table : A qualified table in MDM stores a set of lookup records,and also supports qualifiers, u201Csubfieldsu201D that apply not to the qualified table record by itself, but rather to each association of a qualified table record with a main table record. MDM supports multiple simultaneous qualified tables.
Tables are also Categorized as Object Tables like :
Images : This table is for storing Images
Sounds : This table is for storing Sound File.
Videos : This table is for storing Video Files .
Binary Objects : This table is for storing Binary Objects.
Text Blocks : This table is for storing block of text.
Copy Blocks : This table is for storing block of text interpreted as a Copy.
Text HTML`s : This table is for storing block of text interpreted as a HTML.
PDFs : This table is for storing PDF files.
There are various types of Special Tables , i have mentioned below:
Image Variants : Used to define the structure
and format of each of the variants for each image. Each variant is a modified version derived from an original image; the original image is never modified.
Masks : In this defined subset of records are included in Mask i.e. in any scenario whether new records are added or deleted in the repository the records in the Mask remains the same unless edited by the user.
Families : Used to further partition main table records in each category into smaller groups based upon the values of other fields and/or attributes.
Relationships : Used to define each of the different record-level relationships. Each relationship can be either bidirectional (sibling) or unidirectional (parent-child).
Workflows : Stores the workflows of an MDM repository, where each workflow is stored as a record in the table.
Name Searches : Unlike Masks in case of Name search there are again a defined set of records but those records are selected on the basis of Search Selection. In this case if a record is added then the record is checked whether it fulfills the particular search criteria if it does than it is added to the Name serach else not.
Data Groups : Stores the hierarchy of data groups used to break the entire set of objects in the MDM repository into manageable subgroups.
There are various types of System Tables :
Roles : A single table named Roles. One of three tables used to implement MDM repository security and access control. Each role can selectively grant or deny access to any MDM function and to any table or field. This table is managed in the MDM Console and is not visible in the MDM Client.
Users : A single table named Users. One of three tables used to implement MDM repository security and access control. Each user can have one or more roles. This table is managed in the MDM Console and is not visible in the MDM Client.
Connections : A single table named Connections. One of three tables used to implement MDM repository security and access control. Contains an entry for each currently connected MDM client application, which can be terminated by the MDM Console user. This table is not visible in the MDM Client.
Change Tracking : A single table named Change Tracking. Allows you to specify the fields for which adds, modifies, and deletes should be tracked and stored in the Change Tracking table.
Remote Systems : A single table named Remote Systems. Used to define the different remote systems for import and export. Each specifies whether it supports inbound, outbound, or both. This table is managed in the MDM Console and is not visible in the MDM Client.
Ports : A single table named Ports. Used to encapsulate the logistical and configuration info for inbound and outbound processing of MDM data, for consolidation and distribution respectively. This table is managed in the MDM Console and is not visible in the MDM Client.
Links : A single table named Links. Used to specify the URLs that can be used as the target of an embedded browser in the Web tab in the MDM Client. This table is managed in the MDM Console and is not visible in the MDM Client.
XML Schema : A single table named XML Schemas. Used to identify the XML schemas for import and syndication. Each XML schema is the name of an .xsd file. This table is managed in the MDM Console and is not visible in the MDM Client.
Reports : A single table named Reports. Contains an entry for each report file generated by the various MDM repository operations, which can be accessed and viewed by the MDM Console user. This table is not visible in the MDM Client.
Logs : A single table named Logs. Contains an entry for the log files generated by the MDM Server, which can be accessed and viewed by the MDM Console user. This table is not visible in the MDM Client.
