Why data modeling is better with erwin erwin Data Modeler has been the most trusted name in data modeling for more than 30 years. Modern, customizable modeling environment Automate complex and time-consuming tasks for more effective database design, standardization, deployment and maintenance across all your database platforms.

Visualize complex business and technical data structures, automatically generating data models in a single, intuitive interface. Roundtrip engineering Forward- and reverse-engineering of database code and model exchange ensures efficiency, effectiveness and consistency in designing, standardizing, deploying and documenting data structures for comprehensive enterprise database management. When you resolve a transform, ERwin preserves the model objects that the transform creates but deletes the source objects.

To resolve a transform, go to the Model Explorer and right click on the transform. From the context menu, choose Delete and then choose Resolve. NOTE: If you have a model source linked to the model in which the transform was applied, the link between the transformed objects and the source objects in the model source will be broken when the transform is resolved.

When you reverse a transform, ERwin preserves the source objects and deletes the transform and the model objects that the transform creates.

To reverse a transform, go to the Model Explorer and right click on the transform. From the context menu, choose Delete and then choose Reverse. Once a model has a model source, ERwin automatically tracks the changes to the objects that were contributed by the model source. At any time, you can use the Sync with Model Source wizard to import and export changes between a model and its source.

The Sync with Model Source wizard takes you step-by-step through the process of selecting the types of objects and changes that you want to compare and synchronize.

You can also define case conversion and maximum length rules for logical and physical model objects, and specify a file to enforce naming standards in the target model. Whether you import or export changes, ERwin updates the models and the Model Sources Properties dialog with the date of the synchronization. Managing Standards When multiple individuals or groups are responsible for designing a set of data models, the enforcing of standards is a critical element.

Typically, the naming of objects and the mapping of datatypes are primary areas in which inconsistency can be a problem. ERwin provides built-in tools to help you manage the naming conventions and datatype standards that you apply across your enterprise models.

Naming Standards ERwin has a wide-range of naming standard features that can help you develop new standards or implement existing standards. You can take full advantage of all of the naming standard features or use only those enforced by your organization.

In this dialog, you define the naming standards for the current data model. You can specify the case lower or upper and maximum length for physical objects. For all model types, you can specify how ERwin responds to non-unique names ask, allow, or disallow. In this editor, you can specify separate naming standards for logical and physical objects.

In the Glossary tab on the Naming Standards Editor, you can either import an existing names glossary or build one from scratch. You can define how these standards are implemented, and create entries including business terms, and abbreviations, that are relevant to your business.

For each ERwin model in which you use naming standards, you must attach a naming standards file. You can apply a naming standards file to multiple models.

When you attach a naming standards file to a data model, ERwin automatically applies the standards and conventions defined in the file.

You can also use the file to check compliance of the names of objects in the model, which is similar to a spell checker in a word processing application.

ERwin uses the naming standards file as a dictionary and compares the names in the data model to the names in the dictionary. When it finds a discrepancy, ERwin stops to let you decide whether to ignore or replace the non-compliant name. ERwin includes macros designed to make it easy to distinguish between their application in the logical and physical model types. Datatype Mapping A datatype is a predefined set of characteristics for an attribute or column that specifies field length, acceptable characters, and optional and required parameters.

For example, the datatype char 18 specifies that the column can store up to 18 alpha and numeric characters. By default, ERwin applies a datatype to every attribute in a logical model and to every column in a physical model. In the logical model, the datatype is determined by the domain from which the attribute inherits its properties or from the datatype that you assign. In the physical model, the datatype is determined by the default value specified by the target server or the datatype that you assign.

Considering the large quantity of attributes or columns a data model usually has, it can be quite tedious to manually assign and maintain consistency of datatypes. For this reason, ERwin has several tools that help you with this task. The Datatype Standards Editor can be used to edit the default datatype mapping for your logical and physical models. For physical models, you can edit the default datatype that ERwin automatically attaches to each column.

For logical models, you can add logical datatypes and assign the datatypes to the attributes in the logical model.

You define the datatype mapping standards by specifying how logical datatypes map to the available datatypes for your target server. If you have database applications running on multiple server platforms, you can map datatypes for all of the target servers. For each ERwin model in which you use datatype standards, you must attach a datatype standards file. If you open an ERwin model and you have not attached a datatype standards file, ERwin uses the default datatype mapping.

Of course ERwin lets you define your datatype mapping standards once and apply them to multiple data models. On the Tools menu, when you choose Datatypes and then choose Model Datatype Options, you can specify the datatype mapping file that you want to apply to the current model.

Preserving Model History You can save historical information for your model, entities, attributes, tables and columns. Using the History feature, you can track meaningful changes to derived and transformed models, as well as routine information about the creation and revision dates of your models.

To set the history options, from the Model menu, choose Model Properties. In the Model Properties dialog, click the History Options tab and select check or clear uncheck the history options for the model objects whose history you want to preserve. You can save historical information for the following events: When you create a logical model and add entities and attributes.

When you derive a physical model from a logical model and create tables and columns in the derived physical model. When you reverse engineer a database or script file and create tables and columns in the new model. You can open the Whats New menu item in the ERwin Help menu to review new features and related overview topics. Perform a normal file open and point to the old 3.

ERwin 4. ERwin begins splitting the model and prompts you to save first the logical-only and then the physical-only model. When the split is complete, the new models will contain a history entry that indicates that they were created by splitting the original model. Additionally, the logical model will be linked to the physical model as its model source. A Model Source is a logical connection that ERwin maintains between related models.

The purpose of this connection is to keep track of objects e. This connection allows ERwin to guide the synchronization of related models when changes are required. For example, when a physical model is derived from a logical model, a model source is created that records the entities that were used to generate the tables in the physical model. This option allows you to report both diagrams and tabular information from a model. HTML format makes model information readily available for publishing on the web.

You can read more about the software required for database connectivity in the ERwin online help. The clipboard image can now be pasted into another Windows application. Contact your Administrator if you need to upgrade your permissions to allow you to create a Program Group. Use the Save as New Model feature to save an existing model with a new model identifier.

When you save a source model as a new model, you break the associative link between the model and any derived models. Open navigation menu. Close suggestions Search Search. User Settings. Skip carousel. Carousel Previous.

The excellence is a probable result of the wonderful skills and depth of knowledge of the authors. But the book is also essential for users of ERwin r8, simply because it provides detailed and easy to follow coverage of the many advanced features of this completely modernized data modeling tool.

Full disclosure requires me to report that I have the privilege of knowing Steve Hoberman personally. The class was great, and my colleagues are still talking about it. Steve is an outstanding and entertaining instructor.

But he is also much more: perhaps the most gifted active author relative to data modeling principles and practices, an obviously successful entrepenuer, and a very nice guy. His teaming with Donna Burbank on this important book is a match made in data modeling Heaven.

Many of us have used ERwin as a data modeling tool for many years. But Erwin r8 represents one of the most radical upgrades of a software package I have experienced in thirty years in the data processing business. It may have been the marketing pressures from competing data modeling products that impelled Computer Associates to invest so much in this upgraded version. In any case, ERwin r8 is a vastly different product, with a great deal more functionality as compared to earlier versions.

In the past, most folks probably learned earlier versions of ERwin intuitively and without formal training. This book absolutely fills in the gap for experienced users of previous versions of ERwin. But it is also an excellent text for users of other products or even for those entirely new to the discipline of data modeling.

DBA’s will likewise be well edified by the many practical examples even of physical data modeling, forward, and reverse engineering contained within the text. Of the very many innovative aspects of this newly enriched product, I was perhaps most thrilled with the treatment of domains. To put this in context, I am a totally committed advocate of Dr.

Codd’s relational model for database. In fact, I am even now rereading Dr. Just this morning, I read over Chapter three, which details the centricity of domains in the relational model.

Codd even holds that domains are “the glue that holds the relational model together”. In this context, the outstanding treatment of domains in ERwin r8 by Hoberman and Burbank is, in itself, worth the price of the entire book. Fellow colleagues, don’t complain that ERwin r8 has such an entirely new “look and feel” from previous versions.

Rather, pick up this excellent and important book; and emerge as the thought leaders and technical experts within your organizations. Get to know this exciting and terrifically enhanced product with Hoberman and Burbank as your guides. God bless. There is an update to the book so look for that one which has a few updates.

The book came as expected.
