# Data Dictionary

Data Dictionary Maintenance |

NOMADS includes the Data Dictionary Maintenance utility for building and maintaining the data dictionary. This utility presents all the different options and fields necessary to complete the basic steps for creating definitions in the data dictionary.

These basic steps include:

- Identifying the database file
- Defining the elements
- Defining the keys
- Copying the updated definition to the physical file

In addition, the data dictionary can be created from an external database (ODB, MySQL, OCI, ADO or DB2). See Using External Databases to Create a Data Dictionary.

Data Dictionary Maintenance is displayed below with a sample entry:

To invoke Data Dictionary Maintenance, use one of the following methods:

Location | Method
From the PxPlus IDE Main Launcher | Expand the Data Management category and select Data Dictionary Maintenance.
From the NOMADS Session Manager | Select Dictionary > Maintenance from the menu bar.
From the PxPlus Command window | Select Utilities > Data Dictionary from the menu bar.
From the PxPlus Command window | Enter: DD (or DD tablename)

## Main Panel

The Main panel consists of options for Updating the Data Dictionary and embedding the definition in the physical file. These options include table name, key definition, access logic and notes.

Two tabbed folders, Info and Elements, are provided for specifying details about the data files and their elements:

| Info | Contains fields that are used to describe the physical file, including pathname, group, file type and block size.
| Elements | Presents a grid with fields that are used to define all the data elements within the current definition, as well as for the Global Dictionary.

The Menu Bar and Tool Bar provide options for adding and maintaining the data file definitions.

The Main panel includes the following fields:

Name | Descriptive name for your data source to identify its definition in the data dictionary; e.g. Client List. Maximum 64 characters. Create a new definition by entering a name that does not already exist. You are prompted to confirm the creation of a new definition. See Creating a Definition. #### Note: When a new table name is entered, it will be checked against the Reserved Words list to determine if it is restricted for use in the Data Dictionary. If it is found, a warning message will display. (User Reserved Words Maintenance was added in PxPlus 2020.) Select an existing definition by using any of the following methods: Type the name of the definition. Click the Query Table View button (magnifying glass) for a tree view of table names by Group. For information on creating a filter to locate a specific table name, see Filtering the Table Names Lookup. Click the Query button (binoculars) for a query view of tables by table name. For information on using the query features (i.e. search, sort, filter, etc.), see Run-Time Query. Use the Browse buttons to locate a table name. If you select an existing table with System Journalization and/or File Splitting enabled, a message displays adjacent to the Description field, indicating that one or both of these processes is enabled. If System Journalization is enabled for the table but the system journal file is not open, an Error #69: No Journalization file open is reported.
(Define File Links) | The Define File Links button (chain link with drop-down arrow), located to the left of the Global Dictionary button (globe), allows you to access the File Link Maintenance and File Links Express utilities to create/edit cross-reference linkages that exist between application data files. Clicking the chain link invokes File Link Maintenance. Clicking the drop-down arrow invokes a menu for accessing either File Link Maintenance or File Links Express. If a logical file name has been entered in the Name field, the File Link utilities will automatically be populated with information related to that file. If the Name field is blank, File Link Maintenance will display all file links, and File Links Express will not display any file links. The Define File Links button is disabled if the Global Dictionary button (globe) is selected or if a new file Name is entered but no file definition has been created. (The Define File Links button was added in PxPlus 2025.)
(Global Dictionary) | The Global Dictionary button (globe) loads the Global Dictionary definition. See Global Dictionary.
Description | A short description of the table contents.
Last File Change | This information is updated automatically whenever a change is made in the data dictionary definition (i.e. updating the description, notes, options or elements, changing keys, etc.). This information is used by the Update Physical Files utility. (Last File Change was added in PxPlus 2021.)
Last Physical Update | This information is updated automatically when the file is updated by clicking the Update File toolbar button or selecting File > Update File from the menu bar. This information is used by the Update Physical Files utility. If a data dictionary definition is copied (see Import Dictionary) or a Physical File is entered that does not exist, the Last Physical Update information will be cleared. (Last Physical Update was added in PxPlus 2021.)

## Global Dictionary

PxPlus provides a Global Dictionary to which you can optionally add data elements for global use. When an element is defined globally, you can select and load its definition into various file definitions using the Elements tab. Global Dictionary element definitions are stored in the data dictionary files, providex.ddf and providex.dde.

Loading the Global Dictionary Definition

Load the Global Dictionary definition by clicking the Global Dictionary button (globe) next to the browse buttons on the Main panel. You can also click either the Query Table View button (magnifying glass) or the Query button (binoculars) and then select {Global Dictionary} from the list.

Once the Global Dictionary definition is loaded, data elements can then be added, deleted and maintained using the Data Elements grid, just like any other data definition. See Adding a Data Element to the Global Dictionary.

#### Note:
When the Global Dictionary definition is loaded, other functions (i.e. Rename Table, Delete Table, etc.) will not be available.

(The Global Dictionary button was added in PxPlus 2017.)
(The Data Elements grid was added in PxPlus 2020.)

Adding a Data Element to the Global Dictionary

After the Global Dictionary definition is loaded, new data elements can be added by using any of the following methods:

Method | Description
Create a new element from the beginning | Enter a new element in the last blank row of the Data Elements grid. A new element can also be inserted before or after an existing element. Click the Field Name of the existing element above or before which you want to insert the new element. Right click on this selection and choose Insert Element (Before or After) from the popup menu or use the Insert Element Before (or Insert Element After) buttons beside the grid to insert a new row. Alternatively, create a new element by clicking the button in the Dtl column to invoke the Element Description window. When the new element is saved, it is added to the bottom of the Data Elements grid. Use the Move Up/Move Down buttons beside the grid to reposition the new element. #### Note: When a new element name is entered, it will be checked against the Reserved Words list to determine if it is restricted for use in the Data Dictionary. If it is found, a warning message will display. (User Reserved Words Maintenance was added in PxPlus 2020.)
Create a new element from an existing element | In the Data Elements grid, click the Field Name of the existing element with settings you want to use for the new element. Right click on this selection and choose Repeat Element from the popup menu. The new element is inserted below the existing element with the same settings and is initially assigned the same Field Name ending with _ (underscore) and a number (e.g. Address_1). The settings for the new element can be modified as needed.
Add an existing element from another table | On the Main panel, select the table containing the element you want to add to the Global Dictionary. In the Data Elements grid, click the Field Name of the element you want to add to the Global Dictionary. Right click on this selection and choose Add to Global Elements from the popup menu or use the Add Selected Data Element to Global Dictionary button (globe) beside the grid. A message will display when the Global Dictionary has been updated. To verify, load the Global Dictionary definition and review the Data Elements grid. #### Note: This method does not remove the selected element from its originating table.

## Info and Elements Tabs

The Info tab describes features about the physical database file; i.e. pathname, group, file type, and size. The Elements tab provides various options and settings for defining elements in the physical files.

#### Note:
Some settings, as well as some data dictionary utilities, can be invoked via the Data Dictionary Maintenance Menu Bar.

These tabbed folders consist of the following:

Info
Physical File | Pathname of the actual database file - either a Fixed value (e.g. XX_AR) or an Expression (e.g. %COMPANY$+"_AR"). Click the Query button to select a file.
File Type | (Display Only) Indicates whether the current file is a Native (PxPlus) file, a database Link file, or a database Prefix file. (The File Type was added in PxPlus 2023.)
View Prefix File Entry/Link File Contents | (Available when File Type is a database Prefix File or a database Link File) Button (beside File Type) that is used to display the contents of a database Prefix file entry or Link file in view-only mode. This button is disabled for Native files. Example: (The View Prefix File Entry/Link File Contents button was added in PxPlus 2023 Update 1.)
Options |
Notes | A multi-line input control used for entering notes about the table and its use. Press Enter to start a new line. Maximum 1024 characters. When done, press the Tab key prior to exiting or using the Browse buttons; otherwise, changes to the notes will not be saved. (The Notes input control was added in PxPlus 2021.)
Group | Group name for assigning files to a common theme or application; e.g. Accounting, Billing, GL.
Type | (Available when File Type is Native File) File type to create. Click the drop-down arrow for a list of file types (below). See Supported File Types.
Variable Length | VLR (variable-length record)
Enhanced Format (2GB limit) | Limited EFF
Enhanced Format (>2GB limit) | Unlimited EFF
Fixed Length | FLR formatted files
Block Size | (Available when File Type is Native File) Maximum file size in kilobytes. The default setting allows PxPlus to decide the recommended file size for the file type; e.g. VLR (1-31), FLR (1-32), and EFF (4-63). The default size is computed by taking the largest key size and multiplying by 200. This is compared with the record size, and the higher of the two is rounded to the nearest 1K. The desired block size can also be selected.
Separator | (Available when File Type is Native File) Character to be used as a field separator in the file. The field separator must be a Hex string for a single character (e.g. $8A$). The default separator is the setting of the 'FS' parameter ($8A$ if 'FS' not set). #### Warning! DO NOT USE $00$, $01$, $02$, $03$, $04$, $09$ or $0A$ as a field separator in a NOMADS/iNomads environment, as these characters are used within some fields of NOMADS files and would cause NOMADS to malfunction. Avoid $1B$ in general, which begins mnemonics.
Extended Records | (Available when File Type is Native File) Check box to indicate that records will be written as multiples of the size specified during file creation.
Compression Type | (Not Applicable to FLR Files) Indicates simple compression to record data. Click the drop-down arrow for a list of selections. This field is disabled when File Type is Link File or Prefix File.
Convert to Text for Version Control System | (Available when File Type is Native File) Check box to indicate whether the selected data file definition will be flagged for conversion to text format for use in the Version Control System.
Force data Validation on WRITE/UPDATE | (Available when File Type is Native File) Check box to indicate that, when the file is opened with an IOL=*, the generated IOLIST is to automatically include the validation options as if an OPT="VALIDATE" was specified. For information on these validation options, see IOLIST directive. #### Note: For Date validation, the system allows empty/null dates by default. To disallow empty/null dates, set the Required flag for the field.
Enable UpdatePlus logic | (Available when Type is Variable Length (VLR) or Fixed Length (FLR). Not Applicable to EFF Files.) Select this check box to enable UpdatePlus™ logic for the Physical File specified. If the file was previously created with UpdatePlus™ enabled (i.e. file was created with OPT="U" - see KEYED directive), this check box will be selected automatically. This check box is disabled when File Type is Link File or Prefix File.
(The Force Data Validation option was added in PxPlus 2017.) (The Enable UpdatePlus logic option was added in PxPlus 2017 Update 0002.)
Elements
Non-Normalized | (Available when File Type is Native File) Select this check box to allow the definition of non-normalized data files. See Non-Normalized Data.
Record Format | (Available when File Type is Native File) Record type description for non-normalized data files.

Search Grid for: (F3) | Input field that is used for searching the field names in the Data Elements grid as letters are entered (case insensitive). Access this field by using the mouse or by pressing either the F3 key or the Tab key. (The Search Grid option was added in PxPlus 2021.)
Data Elements | Grid that displays all the data elements in the selected table, along with their settings. This grid can also be used to add, edit and delete a data element. To make bulk changes to multiple data elements in the PxPlus data dictionary and apply the changes to selected tables, use the Bulk Edit Data Elements utility.
Field | Field number that indicates the sequence of elements in the data dictionary.
Dtl | Button that invokes the Element Description window.
Field Name | Unique name of the element. See Name in the Element Description window. #### Note: When a new element name is entered, it will be checked against the Reserved Words list to determine if it is restricted for use in the Data Dictionary. If it is found, a warning message will display. (User Reserved Words Maintenance was added in PxPlus 2020.) Click the Globe button to display a list of Global Dictionary elements and their descriptions. Double-clicking on a Global element adds it to the current row if the row is empty. If the current row is not empty, a message will display. Responding Yes updates the Field Name and all other columns with settings from the selected Global element. Responding No updates only the Field Name but does not update the other columns. Responding Cancel puts back the original Field Name and no other columns are changed. Right click on the Field Name to display a popup menu with the following selections:
Insert Element | Inserts a new element either before or after the currently selected data element. Same as using the Insert Before/After buttons beside the Data Elements grid.
Repeat Element | Repeats the settings from an existing element to create a new element. The new element is inserted below the existing element with the same settings and is initially assigned the same Field Name ending with _ (underscore) and a number (e.g. Address_1). The settings for the new element can be modified as needed.
Delete Element | Deletes the currently selected data element. Same as using the Delete button beside the Data Elements grid or using the Delete button in the Element Description window.
Add to Global Elements | (Not Available when Global Dictionary is selected) Adds the selected element to the Global Dictionary. If a data element with the same name already exists in the Global Dictionary, a message asks if you want to update this Global Dictionary record. Responding Yes updates the Global Dictionary record with the settings from the selected data element. Responding No does not change the Global Dictionary record.
Data Class | Enter the name of an existing data class or use the Query button to load the information from a data class definition into the element's fields. A data class can also be created on the fly. Enter a new name for the Data Class and respond Yes to the displayed message, which launches Data Class Definitions. If the data class assigned to the element has been deleted in Data Class Definitions maintenance, the Data Class name will change to dark red. If a data class with the Class Name "Email" or "URL" (case insensitive) is assigned to a data dictionary field, the input entered for the field will be validated as either an email address or URL on a generated Webster+ HTML page. See File Maintenance Generator. (The dark red text indicating a deleted Data Class was added in PxPlus 2021.) (Email and URL input field validation for generated Webster+ HTML pages was added in PxPlus 2021 Update 1.)
Description | Brief description of the element, which can be a Fixed value, Expression or Message Library Reference.
Type | Indicate whether the element is Numeric or String.
Len | Set the maximum length of the data field. The system will validate that the length specified agrees with the Format selected; otherwise, a message will display. (Length validation in the Elements grid was added in PxPlus 2021 Update 1.) Numeric field lengths can be defined using implied decimal format. Example: 6.2: 6 represents total length of the field, excluding explicit signs and decimals, where applicable, and 2 represents scaling factor or number of decimal places.
Format | Options that define the format for writing the data field to the file. See Format Mask in the Element Description window.
Display | Print/input format. See Format Mask Options.
Ext | Check box to indicate that the element forms part of an external key and is not duplicated in the data portion of the record. Example: Key: CST_ID$ Data: CST_NM$, CST_ADDR$, CST_PHONE$ In this case, CST_ID$ forms the key and is not duplicated in the data portion of the record.
Req | Check box to indicate that the element is a required field and must contain data before the record can be written in File Maintenance.
U/C | Check box to indicate that the data should always be in uppercase letters. Used by NOMADS sub-systems.
R/O | Check box to indicate that the element is designated as read only or locked. Used by NOMADS sub-systems. (The R/O check box was added in PxPlus 2021.)
(The Data Elements grid was added in PxPlus 2020.)
Move Up Move Down | Buttons used to move the selected data element up or down within the Data Elements grid.
Insert Before Insert After | Buttons used to insert a new element before or after the selected data element. Same as using the Insert Element popup menu option when right clicking on a Field Name in the Data Elements grid. (The Insert Before/Insert After buttons were added in PxPlus 2020.)
Delete | Button used to delete the selected data element. Same as using the Delete Element popup menu option when right clicking on a Field Name in the Data Elements grid.
Undo | (Available when a change is entered only in the Data Elements grid) Button used to undo the last change(s) entered only in the Data Elements grid. The Undo button will not undo any changes entered using the Add/Edit Notes button. It will also not undo any changes entered in the Element Description window (accessed from the Dtl column). #### Important Note: The Undo button will become disabled if the Element Description window is accessed immediately after changes have been entered in the Data Elements grid. If this happens, the previous grid changes cannot be undone. (The Undo button was added in PxPlus 2020.)
Add/Edit Notes | (Available when a new data element is entered or an existing data element is selected) Button used to add (or edit) notes for a new or existing data element. Maximum 1024 characters. The button's appearance and tooltip change to indicate that a note was added for the element. Alternatively, notes can be added or edited for an element in the Element Description window by using the Notes input control on the User Aids tab. (The Add/Edit Notes button was added in PxPlus 2022.)
Update Global Dictionary Elements in other Files | (Available when Global Dictionary is selected) Button used to invoke the Update Global Dictionary Elements window. If the selected global element does not exist in other data tables, a message will display.
Add Data Element to the Global Dictionary | (Not Available when Global Dictionary is selected) Button used to add the selected element to the Global Dictionary. Same as using the Add to Global Elements popup menu option when right clicking on a Field Name in the Data Elements grid. If a data element with the same name already exists in the Global Dictionary, a message asks if you want to update this Global Dictionary record.
