Basic Modeling Demonstrations: Add/Remove, Item, String and Attribute Editing

Code SampleDescription
Add Base Attributes to Person Entity

Add base attributes to selected entities, which represent people.

It also introduces a primary key based upon the entity's name.

Add Definition to Type Entities

Add a definition to selected entities.

The definition applied to the selected entity also includes the object's name automatically, as in "My definition text + entity name +(s)".

Add Parent Name Prefix to Propagating Key

Add the entity name as a prefix to all attribute role names.

It demonstrates how to use the FKColumnPair object.

Add Table Name Prefix Globally

Add a prefix string to the names of all entities in the model.

The macro opens a dialog box prompting the user for the prefix.

If the current active model is logical, it assigns the prefix to all entity names. If the current model is physical, it assigns the prefix to all table names.

Add Table Name Prefix Selectively

Add a prefix string to the names of selected entities in the model.

The macro opens a dialog to prompting the user for the prefix.

If the current model is logical, it assigns the prefix to selected entity names. If the current model is physical, it assigns the prefix to selected table names.

Add Table Owner Globally

For physical models, this code updates the owner field in the table editor for all tables in the active model.

The active model must be a physical model.

Add View Owner Selectively

For physical models, this code updates the owner field in the view editor for all selected entities.

The active model must be a physical model.

Attachment Example

Export attachment data for each bound attachment for every selected table in the active model.

The file name and path are: "C:\Attachment Data.txt.

Attribute Binding Macro

List all the unbound attributes/columns of all the models (logical and all physicals) and domains.

You then can bound the attributes to any of listed domains by clicking the Bind button.

Auto-Align Selected Entities Left

Perform the align left operation (similar to the align buttons on the Alignment Toolbar) for all selected entities.

This macro demonstrates more on how to use entity display objects.

Auto-Color All Entities with FKs

Make all entities with foreign keys purple.

It first selects or highlights all entities in the current submodel. Then it makes all selected entities with foreign keys (which, in this case, are all the entities in the submodel) purple. Finally, it deselects or unhighlights all entities in the current, active submodel.

This macro illustrates how to use entity objects, entity display objects, and selected objects, and how to distinguish among them.

Auto-Combine Selected Entities

Take all the attributes from all the selected entities and add them into one newly-created entity.

It include a separate function GetAveragePoint(), which gets the average x or y coordinate point among all selected entities.

The second parameter determines whether to calculate the average x coordinate or the average y coordinate.

Auto-Convert DatatypeIterate through all the selected entities and change the datatypes for all attributes which use VARCHAR to TEXT.
Auto-Create Data Dictionary and Bound Domain

Create a new diagram, and then create a rule, default, and domain in the data dictionary.

It then binds the rule and default to the domain, and then creates an entity and an attribute. Finally, it binds the domain to the attribute.

Auto-Create Data Dictionary

Quickly create a user-defined data dictionary.

You can use the macro as a template to create user-defined or business-specific data dictionaries.

Insert this macro into ER/Studio's ERSBasicHandlers system (specifically in the '"CreateDiagramHandler(CurDiagram As Object)" section of ERSBasicHandlers) and if the Create Handlers option is checked in ER/Studio's Automation Interface Options, this Data Dictionary is created and populated any time a user creates a new diagram.

Auto-Create New Diagram

Create a new diagram.

The new diagram contains an IBM DB/2 physical model and six entities in the physical model.

Constraint Generator

Generate constraints from the defined reference values.

You must define the reference values in the data dictionary of ER/Studio. The macro can select from bound attributes, all attributes, bound domains or all domains. This is chosen with the radio buttons at the bottom of the dialog.

Note that you must insert the constraint into the check constraint/rule tab of the domain or attribute.

Convert Name Case

Convert the case of Attributes, Columns and Entity/Table names for the highlighted tables/Entities in the active SubModel to all upper or lower case.

Works in Logical or Physical models.

Definition Editor

List all the tables and allow the user to update the definition field for the table by pressing the Update button.

There also is a list of columns for the respective table that the user can use to update the definitions for each column.

This macro runs on a logical or a physical model and populates the lists accordingly.

Domain Bindings Export to Excel

List all the tables and allow the user to update the definition field for the table by pressing the Update button.

There also is a list of columns for the respective table that the user can use to update the definitions for each column.

This macro runs on a logical or a physical model and populates the lists accordingly.

Domain Bindings Import from Excel

Export domain bindings for all the attributes in the current model.

The existing columns in the spreadsheet must be left in the same format if the bindings are going to be used to import back into a model.

Note that the attribute data type is only in the spreadsheet for informational purposes when refactoring attributes and columns and assigning them to domains.

Domain Bindings

Import domain bindings from Excel.

It maps domains to attributes or columns depending on the data in the spreadsheet.

The macro provides an interface to select the dictionary where the domains are located and the model to search for the attributes or columns.

When importing into a physical model, the spreadsheet must have the physical table and column names that match the selected physical model. When importing into the logical model, the names in the spreadsheet must match the entity and attribute names.

Example Macro: Loop through Objects of Active Submodel

Bring up a dialog box that shows all attributes bounded to a selected domain.

It also allows the user to unbind specific attributes from the selected domain.

The dialog box contains two list boxes and two buttons. The Domains list box shows all the domains in the diagram. The Bounded Attributes list box shows all the attributes bounded to the selected domain in the Domains list box.

There also are an OK button and an Unbind button. Click Unbind to unbind selected attributes in the Bounded Attributes list box from the selected domain in the Domains list box.

Export Domain Info to Excel

Export the domains and their properties to Microsoft Excel.

Each record in the Excel spreadsheet represents a domain from the data dictionary. You can use the spreadsheet to store domains outside of ER/Studio.

You can update the domain properties in the spreadsheet and import them back into an existing model or a new model using the Import Domains From Excel macro.

The columns in the spreadsheet must remain in the same order to import them properly.

Export Index Column Info to Excel

Generate an index column report for the active model in ER/Studio.

Each record in the Microsoft Excel spreadsheet represents an indexed column. You can use the spreadsheet to apply naming conventions to indexes.

You can read in the new index name with the Import Index Names from Excel macro from the New Index Name column in the spreadsheet.

Metadata Import/Export and Formatting Examples

The following examples demonstrate various methods of importing and exporting model meta data with MSOffice applications such as Excel and Word. Importing has such uses as transferring spreadsheets or lists of names and attributes into your model. Exporting might be used for a presentation or report.

Pre/PostSQL Demonstrations for Selected Target Databases

Metadata Operations and Target Database Operations

OperationDescription
Generate Partitions for OS390 Clustered IndexesProvides and interface to add multiple partitions to clustered indexes. A list of tables is provided. Selecting a table will load the clustered indexes to be partitioned. The storage parameters are uniform across partitions.
Get Related TablesSelects the related parents and/or child of the selected tables. To use the macro lasso a group of entities on the diagram or select them in the diagram tree, then right click on the macro to execute. Parents and children will be selected depending if the option is checked. This macro can be used to assist in submodel creation.

ImportDataDictionary - Import Data Dictionary objects from a flat file. The imported file has to follow a specific format guidelines listed in the comments with examples.
































Index Naming - Applies naming conventions to all types of indexes. It provides an option to use the selected tables or all tables. The prefix and suffix variables can be used to add company specific conventions to the beginning and/or end of the target name. The target name can be either the existing name, table name, tablespace name or database name. The tablespace and database can only be used for applicable platforms such as Oracle or DB2. Truncate parameters can also be specified to remove the first N characters or the last N characters of the target name. Another parameter can also be used to limit the total number of characters in the target name. These are applied before the prefix and suffix are added.

Name Foreign Constraints - Prompts the user with a dialog to specify the naming convention for Foreign Constraints. It will then name all the constraints using the parent and child table names. It will also make sure the name is unique by adding an index for the last characters of duplicate names.

Name Primary Constraints - Names all primary key constraints with the given naming conventions. The table name with either a prefix or suffix.

ProcedureEdit - Adds a Synonym to a specified table/view. The macro will prompt the user with a dialog to choose the table/view. The synonym code will be inserted into the PostSQL of the specified table/view.

Selectively Output PK and FK DDL - Outputs DDL for primary and foreign constraints for all selected tables. To operate, selected the desired tables, then right-click on the macro to execute. The DDL can be previewed or written to a file.

Selectively Update Oracle Index Storage - Provides a list of tables from the active physical model. The tables in the right box will be updated with the specified storage parameters. Tables can be added and removed from the updated list.

Selectively Update OS390 Table Storage - Provides a list of tables from the active physical model. The tables in the right box will be updated with the specified storage parameters. Tables can be added and removed from the updated list.
