Naming Conventions

Toad Data Modeler

I’d like to take this logical model:

facility category

facility category identifier
1:1
|
|
|
0:M

facility

facility identifier

and create the following relational model:

t_fac_cat

fac_cat_id
1:1
|
|
|
0:M

t_fac

fac_id
fac_cat_id <NN,FK>

I’ve created the logical model and used ‘Simple Model Conversion’ to convert to Oracle 10g.

I then applied the following naming convention to the physical model:

General: Everything checked.
Naming Convention Rules:
‘entities’ prefix ‘t_’ case ‘lowercase’
‘attributes’ prefix none case ‘lowercase’
Glossary Character Replacement: =_ (i.e., =)
Glossary Word Replacement:
facility=fac
category=cat
identifier=id

and get:

t_facility_category

facility_category_identifier
1:1
|
|
|
0:M

t_fac

facility_identifier
facility_category_identifier <NN,FK>

The ‘t_’ prefix worked. The space replacement with underscores worked. Entity ‘facility’ was abbreviated to ‘fac’. However, none of the other abbreviations were applied. It appears the space->underscore replacement occurs first and prevents the matching of the rest of the abbreviations. If that is what is happening, is there another way to get the naming I want?

You are absolutely right. The space->underscore replacement occurs first and prevents the matching of the rest of the abbreviations. We are planning to change this behaviour in the next release (CR #69743) .

Workarround is either to add all words into the glossary (e.g. facility category = fac_cat ), that could be a lot of words or not to replace the space character with the underscore character in the naming convention rules and to run later a simple macro that would replace the space character with the underscore character.

Thank you for your remark.

David,

That’s good news that this issue is being addressed.

Thanks for your help.

David suggested:

“… or not to replace the space character with the underscore character in the naming convention rules and to run later a simple macro that would replace the space character with the underscore character.”

This works pretty well. Here’s the macro I created (i.e., hacked together from two existing macros) to replace spaces with underscores:

function RenameEntityAndAttributes(Entity, Log)
{
var EntityOldName, EntityNewName, Attribute, a, AttributeOldName, AttributeNewName;
EntityOldName = Entity.Name;
EntityNewName = EntityOldName.replace(/ /g,""); //renaming entity
Entity.Name = EntityNewName;
if (EntityOldName!=EntityNewName)
Log.Information(“Entity '”+EntityOldName+"’ was renamed to ‘"+EntityNewName+"’");
for (a=0; a<Entity.Attributes.Count; a++)
{
Attribute = Entity.Attributes.GetObject(a);
AttributeOldName = Attribute.Name;
AttributeNewName = AttributeOldName.replace(/ /g,""); //renaming attribute
Attribute.Name = AttributeNewName;
if (AttributeOldName!=AttributeNewName)
Log.Information("- Attribute ‘"+AttributeOldName+"’ was renamed to ‘"+AttributeNewName+"’");
}
}

function Main(){
var App = System.GetInterface(“Application”);
var Model = App.ActiveModel;
var WS = App.ActiveWorkSpace;
var Log = System.CreateObject(“Log”);
if(Model==null) return;

var i, Obj, origName;
var Counter = 0;
Model.Lock();

for(i=0; i<Model.AllObjects.Count;i++)
{
Obj = Model.AllObjects.GetObject(i);
if (Obj.ObjectType==2502)
{
RenameEntityAndAttributes(Obj.ParentBase, Log);
}
}

Model.UnLock();

System.ShowMessageDialog(1000,‘ReplaceSpacesFromEntitiesAndAttributesNamesDialog’,‘Renaming complete. Details are displayed in the Log area.’,3,4);
System.RefreshModel(Model);
}

I am trying convert logical to physical and in logical i have a attribute name
Column Load Date
I did simple conversion and applied Naming standards in which I set up glossary for load date
Load Date = _LD
But when i apply it is simply ignoring spaces and follwing is the result
ColumnLoadDate
I am trying to get Column_LD
