#PowerDesigner adds support for #SnowflakeDB

In the latest version of PowerDesigner (16.7), SAP have added support for Snowflake to the Physical Data Model. There isn’t space here to demonstrate everything they’ve provided so here’s a summary.

There are new properties for Tables, Columns, etc.:

SchemaNew Physical Options tab
UserNew Options and Object Properties tabs
TableNew Persistence property, plus Physical Options
ReferenceNew Options tab
ColumnNew Collation property, plus Physical Options

There’s a raft of new object types you can create:

  • File formats
  • Integrations
  • Managed Accounts
  • Network Policies
  • Notification Integrations
  • Pipes
  • Procedures
  • Resource Monitors
  • Sequences
  • Object Shares
  • Storage Integrations
  • Warehouses

To find out more about these new features, follow these two simple steps:

Work Smarter with #PowerDesigner – improve data modelling productivity with this new model extension

SAP PowerDesigner is a great data modelling tool with features that differentiate it from the rest of the market, increasing the productivity of data modellers.

The CDM LDM Productivity model extension from Metadata Matters improves the productivity of data modellers still further, helping them to visualise, manage and validate their models, concentrating on making modelling decisions, and spending less time on routine tasks.

Attach the CDM LDM Productivity model extension to any Conceptual or Logical Data Model and start using the new features right away. Better still, deploy the extension via the PowerDesigner Repository and have it attach itself to every new Conceptual or Logical Data Model automatically—updates to the extension will automatically be made available to every model that it’s attached to.

The CDM LDM Productivity model extension extends model validation and adds extra options to contextual menus. For example, here are the new options in the contextual menu for an Entity:

Metadata Matters will work with you to customise the extension to meet your own unique requirements – the cost of the extension includes a day of customisation effort.

Here’s a summary of the capabilities provided:

Completeness of DiagramsHow much time do you spend examining a diagram only to discover that something vital is missing? Eliminate the doubt –
– for a given Entity, select from lists of linked objects to add to your diagram
– add all child Entities for an Inheritance
Entity ParentageWhich Entity (or Entities – there may be more than one) is the ‘Ultimate Parent’ of a sub-type in a deep Inheritance hierarchy? The answer may surprise you, and we know that modellers do not like surprises.
Entity Hierarchy DiagramsCreate and refresh a diagram that guarantees to show you the full structure of all the Inheritance hierarchies that an Entity participates in. Here’s a simple example:
Here’s a much bigger example, for an Entity that participates in two hierarchies:
Entity Proximity DiagramsCreate and refresh a diagram that guarantees to show you everything linked to an Entity.
Modelling StandardsSave thinking and working time by automatically moving ‘Primary Identifier’ Attributes to the top of the list and moving the Primary Identifier of an Entity to the top of the list of Identifiers. Ensure that Entity Attributes or Data Items with the <undefined> data type are linked to the default domain.
Applying Naming StandardsConstruct meaningful and useful names for Relationships, Identifiers and Inheritances.
Model ValidationExtend the built-in model validation with new custom model checks, helping you to:
* apply your modelling and naming standards
* check for double-spaces in object names
* check Relationship role names
* be aware of multiple parent Entities or alternate Identifiers
Hiding and Showing Migrated AttributesIf you chose to work with the Logical Data Model but you would like your diagrams to look more like diagrams in the Conceptual Data Model you can – by hiding selected classes of Attributes. Changed your mind? You can always show them again.
Diagram Auto-layoutSpecify the required type of layout and orientation for every diagram and apply it when you want to.
Hiding and Showing Diagram ContentShow or Hide Link Symbols. Remove graphical synonyms or shortcut symbols from a diagram.
Using DiagramsStraighten a link symbol by removing all the corners. A simplified way of changing page size and orientation.
Model StructureIf you’re using Packages in your models, you’ll be aware of the potential pitfalls and how much work there can be if you change your mind about the Package structure. The extension provides two useful features:
* Safely remove a Package from the hierarchy without losing content
* Check if a Relationship and the child Entity have the same owner
Managing Text PropertiesReplace an object Comment with the Description or vice versa.
Scripting SupportOutput the Display Preferences to the Output window.

Work smarter with #PowerDesigner – How to display a ‘Relationships’ tab for entities

Data modelling tools vary in the kinds of dependencies that you can create between objects. For example, they all recognise that entities in a Conceptual or Logical Data Model (CDM or LDM) can participate in Relationships – when you view or edit the properties of an entity most (perhaps all) tools will show you a list of relationships as part of the dialogue. They might also show you other dependencies, such as a list of diagrams the entity appears on, a list of related tables in Physical Data Models, or some Data Lineage or other mappings. With most tools, that’s the limit. PowerDesigner goes beyond these basic modelling and development connections, allowing you to create several other different types of dependencies:

Shortcuts, Replications, Traceability Links, Related Diagrams, Extended Collections (extensions to the out-of-the-box capabilities)

One side-effect of this power and flexibility is the impact on the entity properties dialogue – most of these dependencies are all shown on the same tab. In the example below, the Contribution entity participates in four relationships, listed on a sub-tab; I can see that the entity also appears on at least one Diagram (indicated by the presence of the Diagrams sub-tab). There could be more sub-tabs, if the entity has other types of dependencies.

You might prefer to see relationships listed in a tab of their own. Well, with a little work, you can add that tab for yourself; you just need a simple model extension.

You create or use Model Extensions to change the way that PowerDesigner works, usually by adding additional metadata, or additional features such as imports, exports, and new object properties. In this example, we’re not adding a new feature, merely exposing some metadata that already exists – the Relationships collection.

Here’s what you need to do:

  • On the Model menu, select Extensions
  • Create a new entry in the list – just type the name – then click on OK
  • The new extension will appear in the Browser
extension in Browser
  • Double-click the extension to open it, then right-click Profile, and add the Entity metaclass to the extension
  • Add a new Form to the metaclass, call it Relationships
add form
  • Add the Relationships collection to the Form, then close the extension editor
  • Here’s the new tab

I’ve used this technique in other places as well, such as adding a Sub-Requirements tab to Requirements in a Requirements Model.
