Toolboxes in a geodatabase in Informix
You can create new toolboxes in your geodatabase by right-clicking the geodatabase in the Catalog tree, pointing to New, and clicking Toolbox.
Toolboxes in ArcGIS for Desktop
If you have created a toolbox in your geodatabase, it would appear in the Catalog tree with the following icon:
 
The name of a toolbox in a geodatabase in Informix contains the database name followed by a colon (:), the name of the owner of the toolbox, and the name of the toolbox itself.
For example, a toolbox, MoveData, owned by user editor, in a geodatabase named biggdb would be listed as biggdb:editor.MoveData in the Catalog tree.
Toolboxes in an IBM Informix database
Toolboxes are represented in a DBMS as a business table to store information about the tools in the toolbox and the gdb_items and gdb_itemtypes system tables to keep track of both the toolboxes and tools.
The following are the tables for the MoveData toolbox:
The business table and gdb_items table are associated by the name—the value in the name field of the gdb_items table corresponds to the business table name. The gdb_itemtypes table identifies the toolbox object as a toolbox and the tools in it as tools.
The gdb_items and gdb_itemtypes tables reside in the geodatabase administrator's schema (sde) and the business table resides in the user's schema. The gdb_items and gdb_itemtypes tables are created when you create the geodatabase; the business table does not get created until you create the toolbox.
For a definition of the gdb_items and gdb_itemtypes tables, see System tables of a geodatabase in Informix.
The following is the definition for a toolbox business table:
| Field name | Field type | Description | Null? | 
|---|---|---|---|
| objectid | integer | Unique identifier of the tool | NOT NULL | 
| type_ | smallint | Code that indicates the type of tool: 1 = function tool, 2 = model tool, 3 = script tool, or 4 = custom tool | NOT NULL | 
| name_ | varchar(255) | Name of the tool | NOT NULL | 
| displayname | varchar(255) | The label for the tool | |
| description | varchar(255) | Description of the tool | NOT NULL | 
| category | varchar(255) | Name of the toolset in which tools are grouped; this includes the path to the toolset if it is a toolset nested inside another toolset. | |
| tool | BLOB | All other properties of the tool | 
The following are the tables for a toolbox named movedata.

Dashed lines indicate implicit relationships between columns.
Toolboxes in an XML document
Toolboxes are data elements and, therefore, are prefaced with a DataElement tag. The data element type will be esri.DEToolbox.
The following is the XML (including metadata) for a toolbox named MoveData:
<DataElement xsi:type="esri:DEToolbox">
