Access details related to tables, columns, and field labels in your instance.

## Tables

All of the information on an instance is stored in tables, which consist of a series of records. The record in turn holds a series of fields that hold the individual bits of data and can be viewed either as a list or a form.

The Tables \[sys_db_object\] table contains a record for each table in the database.

Access the Tables \[sys_db_object\] table by navigating to System DefinitionTables. From the Tables list, an administrator can create a custom table, or select an existing table to view table details. In the table form, an administrator can access table administration options.

* View, add, or modify columns with a searchable and sortable embedded list, define the auto-number format, make the table extendable by other tables, and create modules for the table.
* Launch a schema map for a table by clicking the Show Schema Map related link.
* Open the dictionary entries for the table by right-clicking the form header and selecting Show Dictionary Record.
* Navigate directly to the default list or form view for the table by clicking the Show List or Show Form related link.
* Delete all records from a table by clicking the Delete All Records.

## Dictionary Entries

The Dictionary Entries \[sys_dictionary\] table, also called the System Dictionary, defines every table and field in the system. It contains
information about data type, character limit, default value, dependency, and other
attributes of a field.  
Access the system dictionary in one of these ways:

* To see the system dictionary list view, navigate to System DefinitionDictionary.
* To view particular dictionary definition, right-click the list header, form header, or field label, and select Configure Dictionary.

## Field Labels

The Field Labels \[sys_documentation\] table, also called the Language File, contains information about the labels and hints for each table and
column in the system.  
Access the language file in one of these ways:

* To see the list view, navigate to System DefinitionLanguage File.
* To see the field label for a particular field, right-click the field label on the form.
