Data for InterSystems products (table row data, object instance data) is stored in global variables.
The data size of each global can be obtained by clicking the properties of the global you want to view from the Management Portal > System > Configuration > Local Database > Globals page, and then clicking the Calculate Size button on the Global Attributes page that appears.
To display the data sizes of globals in a namespace, you can call ^%GSIZE utility on the terminal.
The method of execution is as follows.

USER>do ^%GSIZE

^DeepSee.ActiveTasks contains no data

Another option is to use the %SYS.GlobalQuery_Size() class query documented here, it can be conveniently used from SQL like:

call %SYS.GlobalQuery_Size('c:\intersystems\iris\mgr\',,'*',1,,1)

It can be called from the portal SQL or any SQL odbc/jdbc client tool.

I urge folks to avoid ^%GSIZE with show details = yes unless there is an urgent need for recent size info. If you're going to read the whole database, I'd suggest an Integrity Check instead. It provides the same information but also verifies integrity.
