Comparison of features in CMDB 1.0 and 2.0
The following table compares how different features are implemented in CMDB 1.0 and 2.0:
| Feature | CMDB 1.0 | CMDB 2.0 |
|---|---|---|
| Reporting | You cannot create a custom report that involves more than two classes (objects). For example, to generate a report in CMDB that gives data about which LAN endpoints are used by which computers, you must refer to three objects: Base Element, Computer System, and LANEndPoints. | All classes are part of one object (as field sets), therefore, you can create reports that involve any number of classes. |
| Field definition of a class | The CMDB_AttributeDefinition class is used to recognize attributes (fields) that belong to a class (object). | The field sets and field definition of the Base Element object provide the field definition of a class. |
| Data import | Records are first imported in a flat table, called staging table, and then saved in the individual objects. Therefore, the batch size is small. | Records are imported directly into the Base Element object; therefore, the time required to import data is less. Pentaho packages for importing data into BMC Remedyforce are available on BMC Communities. The folders for CMDB include 2.0 in the names. |
| Data export | Exporting data is difficult because one configuration item record is saved in more than one object. | Exporting data is easy because all records are saved in the Base Element object. |
| Custom fields | Custom fields are added in the required class. You can then access them in the class by navigating to the Remedyforce Administration > Configure CMDB 1.0 > CMDB Custom Attributes page. Custom fields appear on the Custom tab on the Instance Editor. | Custom fields are added to the
|
| Instance Editor | Custom fields appear on the Custom tab, and you cannot add or remove the fields on the General tab. | To add or remove a field from the General tab, add or remove the field from the Base Element field set. To add or remove a field from the Specifications tab, add or remove the field from the field set of the required class. |
| Field tracking | You can track fields that belong to the Base Element object, shown on the General tab on the Instance Editor. You cannot track fields on the Specifications and Custom tabs. | Because fields of different classes are stored in the Base Element object, you can track any field. However, Salesforce allows you to track only 20 fields in one object. |
| Search | You can search fields of the Base Element object only. Therefore, search is limited. | All fields (or attributes) are stored in the Base Element object, and the fields of the Base Element object are searched. Therefore, you can search data for all classes. |
| Data storage | Different objects are created for different classes; attributes that are common in all classes are stored in the When a record is saved, data is saved in the | All information is stored in the When you save a record, the record is created only in the |
