Data Inventory Manager
|This page is under review|
After standardising auxiliary data, the next step in setting up IMSMANG is to implement the necessary customisation of the database reflecting the identified data requirements. Information managers have the possibility to modify the database in two ways:
- modifying existing data fields i.e. data fields that exist in the database from installation which often are referred to as system fields
- creating new data fields which are referred to as Custom Defined Fields (CDFs).
The objective of this step is to ensure that all data fields and options necessary for programme operations are available in IMSMANG. This step should be completed prior to designing forms for data entry so that these changes are reflected on the Data Entry Forms.
|IMSMANG does not automatically change Data Entry Forms when changes are made in the Data Inventory Manager.|
IMSMANG comes with more than 1,000 system fields from installation and therefore it is important to search in the Data Inventory Manager before adding CDFs in order to determine if a data field already exists before adding it as a CDF.
The Data Inventory Manager shows the data field by item and sub-categories so information managers can quickly navigate and find the data fields. It is also possible to add more categories and move fields between categories.

|If there are many fields/CDFs in one category the Data Inventory Manager may be slow to load. If that is the case then move fields/CDFs into a new or existing category.|
Modify Existing Elements
In addition to creating new data elements using the Data Inventory Manager, information managers can customise the values of existing pick lists to reflect local programme needs. Information managers can add new values to the pick lists and deactivate existing values. Deactivating existing values does not remove the values from the database nor does it change existing data or forms. Rather, it removes the options from the Source Tree in the Form Designer so that the values can no longer be added to new forms.
For example, an existing “Safety and Security Threat” data element for land could include the values that are listed on the left side of the figure below. However, information managers can deactivate the values that their programmes don’t use and add the values that they do, as shown on the right side of the figure.
Modifying Data Elements
This lets information managers track the individual types of land they defined. Likewise, the ability to modify existing data elements gives information managers fine control over all the data elements they want to track in IMSMANG and how they are tracked.
While adding and deactivating new values is an effective and important capability within IMSMANG, information managers should approach changing the text of existing values carefully. Because many values are used across different data elements, for example, the values “Yes” and “No,” modifying these values can have unintended consequences.
|It is preferable to add new values to pick lists and deactivate unnecessary elements than to modify the text of the value.|
Create New Data Elements
Information managers can create CDFs for those data elements not predefined in IMSMANG. IMSMANG does not limit the number of CDFs that can be created for each item; however, it is recommended that information managers use CDFs judiciously because the collection and management of unnecessary data is a substantial contributor to system performance and staff productivity issues in many programmes.
When determining new data elements to add to IMSMANG, it is important to carefully consider the types of data to be collected and the format of the data. Using the correct data type for each element is critical to preserving the ability to search, calculate, sort and report information easily. The table below identifies the data types available in IMSMANG and some search options for each.
|Data Type||Uses||Search Options|
|Date/Time||Storage of dates, times or dates and times. Examples include Date of Accident and Data Entry Date.||Is between, Is in the last|
|Country Structure||Storage of country structure information.||Is In, Is Not|
|Multiple Select||Storage of structured data where values must be confined to certain pre-defined choices. Ideal for structuring data for searching, reporting and translating. Examples include Contamination Type and Drainage Features. Selection is displayed as checkboxes.||Is In, Is Not|
|Number||Storage of all numeric data used for calculations. Examples include Number of Teams and Total Audience Number.||Equals, Not Equal, Is Greater Than/Is Less Than, Is Null, Is Not Null, Is Between|
|Organisation||Storage of organisation information.||Is, Is Not, Parent Is|
|Place||Storage of place information.||Is, Is Not|
|Single Select||Storage of structured data where values must be confined to certain pre-defined choices. Ideal for structuring data for searching, reporting and translating. Examples include Type of Activity and Temperature. Selection is displayed as radio buttons.||Is In, Is Not|
|Text||Storage of unstructured, textual data. Text data can be as small as a few characters or as long as several paragraphs. Text elements are good for storing data that cannot be stored in other formats, such as comments or narrative descriptions.||Is, Is Not, Contains, Does Not Contain|
Dates, Text and Numbers
To create date, text and number fields in IMSMANG, information managers first select the type of item to create a CDF for and the type of CDF. Different types of fields make different operations available. For example, number fields enable calculations, date fields enable date searching and text fields enable text searching. After selecting the CDF, information managers provide a label and an optional description for the CDF.
|Text fields are limited to a set number of characters. Larger amounts of data can be attached to a Data Entry Form and stored in the database.|
IMSMA Enums (Multiple Select and Single Select)
Creating pick lists is one of the most powerful functionalities available in the IMSMANG Data Inventory Manager. Using this functionality, information managers can create rich data fields for each IMSMANG item that are searchable, translatable and customisable. Pick lists preserve data integrity by preventing problems associated with typographical errors, misspellings and other data entry errors, enabling users to compile and compare data easily. When created, the values for the pick lists can be modified to reflect changing needs over time.
Pick list data can be used in tools such as the Impact Scoring tool as well as in sorting and filtering. Data in single-select pick lists can be used to change the display of data on the map based on their values. For example, information managers can show different symbols on the map for different fields such as status, priority and type.
Creating a new pick list in IMSMANG requires information managers to first determine whether the pick list should allow the selection of single values (using radio buttons) or multiple values (using checkboxes). When this determination is made, the values for the pick list can be added and the pick list created. Information managers can also provide translations for the values, which automatically display for users running IMSMANG in other languages.
When the desired data elements are added to the Data Inventory Manager, information managers can proceed to form design to add the elements to the data collection forms.
Using IMSMANG in a different language than English
IMSMANG provides the capability to translate and run the entire system in different languages. To fully translate the system into one or more languages, there are two parts to consider. The GUI i.e. what the user see and the data. How to translate the GUI is described here and how to translate the enumeration values and/or CDFs is described here. If the Mine Action programme needs to be multi-language e.g. Lao and English then two different sets of Data Entry Forms may be developed or the Data Entry Form may contain labels in both languages.
