Accessing data containers and data models


Talend MDM Web UI allows you to access the data container that holds the master data you want to manage and the data model against which the master data will be validated.

One data container uniquely corresponds to one data model and they must have the same name. For more information, see Data containers and Data models.

The following example demonstrates how to access the data model Product and data container Product from the Talend MDM Web UI.

Before you begin

  • The MDM server is up and running.
  • You have imported the MDM demo project, deployed the MDM objects required, and loaded data into the Product data container.
  • You have logged in to the Talend MDM Web UI.


  1. In the upper right corner of the web page, click the button to show the Actions panel.
  2. In the Domain Configuration area, select the Product data container or Product data model from the list.


    The corresponding data model or data container with the same name will be selected automatically.
    If you selected a data container (or data model), but the corresponding data model (or data container) cannot be found, the automatic selection will not be performed.
    Information noteNote: The Data Containers and Data Models available for selection depend on the role and access rights your administrator has assigned you. Contact your administrator/manager if you do not have access to required information.
    If multilingual descriptions have been defined for a data model, you can move your mouse pointer over the data model or its corresponding data container to view in a tooltip the localized description corresponding to the selected locale.
    For more information about how to define multilingual descriptions for a data model, see Creating a data model.
  3. Click the Save button to save your selection.
  4. View the welcome page that is displayed in the center with multiple widgets.


    The Welcome page provides the following widgets:



    Getting started

    Provides direct links to pages of the Web user interface such as Master Data Browser and Journal.


    Allows you to perform a full-text search across the selected data container.

    Information noteNote: Lucene term search, field search, and wildcard search are supported. Besides, Lucene fuzzy search is also supported and enabled by default.
    • Term search: there are two types of terms, single terms and phrases.
      • Single term search: search by typing a single word, for example Doc, which will return all data records that contain the word Doc.
      • Phrase search: search by typing a group of words surrounded by double quotes, for example "Talend Doc", which will return all data records that contain the phrase Talend Doc.
    • Field search: search any field by typing the field name followed by a colon and then the term you are looking for, for example, Team:Doc, which will return all data records whose Team field contains the word Doc.
    • Wildcard search: search by using a single-character wildcard ? or a multiple-character wildcard *.
      • A single-character wildcard search looks for terms that match with the single character replaced, for example, to search test and text, you can use te?t.
      • A multiple-character wildcard search looks for zero or more characters, for example, the search term doc* will match doc, document, and documentation. The multiple-character wildcard can also be in the middle of the term, for example, the search term b*k will match bank, book, and black.
    • Fuzzy search: search by using a single word term followed by the tilde symbol ~ and then an optional parameter that can specify the required similarity. The value of the parameter is between 0 and 1, and the default value is 0.5 if the parameter is not given. For example, to search for a term similar in spelling to roam, such as roams and foam, you can use the fuzzy search roam~0.4.


    Allows you to launch standalone processes manually.

    The processes are listed alphabetically in ascending order based on their descriptions for the current user's language. If the process descriptions are not available, they are listed alphabetically in ascending order based on the process names.


    Provides direct links to all tasks that require the validation or approval of the authorized steward.

    If the current logged-in MDM user is also a Data Stewardship User and has a data stewardship role of Data Steward, there may be alerts to newly assigned Talend Data Stewardship tasks.

    If the user is not configured to be a Data Stewardship User or does not own a Data Steward data stewardship role, there are alerts that no tasks are assigned.

    Statistics: Data

    Allows you to view the actual percentage of master data records per entity in a pie chart.

    An authorized user can click any slice of the pie chart to open the Master Data Browser page which lists the master data records pertaining to the selected slice (entity) with the default view if it exists. However, if the default view is not available, one of the alternative views will be used instead; if no candidate view is available, an error message pops up.

    For more information, see Views.

    Statistics: Entity Events

    Allows you to view the general proportion of triggered events per type in a bar chart.

    Statistics: Journal

    Allows you to view the general proportion of create and update operations per entity in a bar chart.

    Statistics: Matching

    Allows you to view the general proportion of duplicated data records in the integrated matching process in a bar chart.


You can now access the information pertaining to the selected data container using the Menu panel on the left hand side of the page. Any modification of master data will be validated against the selected data model.

Your view of the Menu list and access to certain data depends on the user authorization and access rights set by your administrator. Contact your administrator if you do not have access to the required information.
