    PowerDesigner Interface Defining Global Options
  • General Features Guide Chapter 7 Managing
    Models sections dealing with Naming Conventions
    and Conversion
  • General Features Guide Chapter 14 Model
    Graphics Model Display Preferences

PowerDesigner Options - Display Preferences
  • General General display preferences
  • Windows background, Unit, Grid, Diagram
  • Object View
  • Top level controls name splitting of text in all
    graphics options for none, truncation or word
  • Display options for each type of base object
    options vary by object
  • Format
  • Control of actual graphic symbol size, line
    styles, fill, shadow, font, and custom shape
  • Text cannot be embedded within custom shapes

PowerDesigner Options - Model Options
  • Model level List of PDM objects that can have
    options set
  • Name/Code case sensitivity applies to all
    objects in the model
  • TIP Select Name/Code Sensitivity option to
    ignore the case during comparison, generation, or
    merging of models
  • Ignore Identifying Owner applies to tables,
    views, and stored procedures
  • Column Domain
  • Enforce non-divergence this option determines
    if column properties must be the same as those of
    the domain or if they can differ
  • Column properties that can be set are Data type,
    Check, Rules, Mandatory, and Profile
  • Default data type - the data type that applies to
    columns and domains if no data type is selected

PowerDesigner Options - Model Options
  • Model level (cont)
  • Reference Rules when creating references
  • Unique code forces each reference to have a
    unique code
  • Auto-reuse columns - attempts to reuse an
    existing column in the child table as the foreign
  • Auto-migrate columns - migrates the primary key
    as a foreign key and will optionally migrate the
    domain, checks and rules associated with the PK
  • Default Link on creation - determines if a join
    will be created by default for the reference
  • Default implementation - indicates how
    referential integrity is implemented in the
    reference, either declarative or triggers

PowerDesigner Options - Model Options
  • Naming Conventions Set rules to enforce
    predefined name and code formats for all objects
  • Display set to display either name or code
    values for the model
  • Enable name/code conversion - enables or disables
    the use of conversion scripts and conversion
    tables to generate a code from a name or a name
    from a code
  • Name Code specify the format for constraints
    on length, character case and valid characters
    for objects
  • Naming Template specify a format template for
    use with several types of objects within a model
  • Name to Code Code to Name uses a combination
    of a conversion script and/or a conversion table
    to generate an objects name from its code or an
    objects code from its name

PowerDesigner Options - General Options
  • General general default settings
  • Delete, Browser, Drag Drop, Output log,
    Graphical tool behavior
  • Dialogue define Property sheet behavior
  • Tip Enable Name to Code mirroring option if using
    conversion scripts
  • Editors specify specific editors for different
    file types
  • Variables list of environment variables used
    by PowerDesigner
  • Named Paths logical paths used when paths are
    saved within files
  • Fonts default font settings and naming
    conventions based upon the language version of
    Windows installed on your machine
  • User interface (lists), Code editor (SQL
    preview), RTF editor (description, annotation)
    can be modified
  • Repository general repository interaction
    default settings

PowerDesigner Options Generation Options
  • Inter model
  • Convert Names into Codes option must be selected
    during inter model generation
  • Object codes are generated from names using
    associated conversion script
  • DBCreateAfter Stereotype
  • Used with stored procedures and views to control
    generation order

PowerDesigner Options Reverse Engineering
  • Reverse engineer into an existing model or a new
  • Selection specify DBMS source to be reverse
    engineered. Either an ODBC data source or SQL
    script file
  • reverse using administrators permission select
    in order to be able to select data in the system
    tables that are reserved to a database admin
  • Options
  • After reverse engineering options that
    potentially can alter the reverse engineered
  • Script terminator terminator used to end the
    statement when reverse engineering via script
  • Target Model includes or allows you to add
    target model(s) to create external shortcuts

Miscellaneous Tips Disable Synonym creation
  • Problem
  • When the auto-layout feature is executed,
    synonyms are sometimes created for several
    object. This functionality is not always desired
    especially when reverse engineering a database.
  • Solution
  • Use the following registry key to deactivate the
    synonym creation
  • HKEY_CURRENT_USER\Software\Sybase\PowerDesigner
  • "SynonymsInAutoLayout" "No" ("Yes" by default)

DBMS Definition File (XDB)
  • What
  • Method used by PowerDesigner that contains
    specifications for a particular Database
    Management System (DBMS). It contains the syntax
    templates for generation, reverse engineering,
    data types and constants for a supported DBMS.
  • Why
  • Used by PowerDesigner engineering to support all
    the DBMS
  • Used by users to alter standard DBMS to better
    suit their needs
  • Used by users to add new DBMS that are not
    shipped with PowerDesigner
  • How
  • Advanced User Documentation Chapter 1 DBMS
    Reference Guide
  • Advanced User Documentation Chapter 2
    Managing Profiles
  • Physical Data Model Users Guide Chapter 13
    Variables in PowerDesigner
  • Physical Data Model Users Guide Chapter 14
    DBMS-Specific Features
  • Review included XDB files for understanding and

DBMS Definition File (XDB)
  • General DBMS Identification and general flags
    that apply for all objects
  • Script - DBMS characteristics, command
    definition, and data type translations for script
    generation and reverse engineering
  • SQL contains values that define the general
    syntax for the database
  • Syntax - Contains general parameters for SQL
  • Format - Contains entries that define script
  • File - Text entries used during the database
  • Keywords - List of reserved words and functions
    available in SQL
  • Objects details for each type of object
    available for generation to and reverse
    engineering from the database

DBMS Definition File (XDB)
  • Script (cont)
  • DataType lists of valid data types including
    conversions to PowerDesigner internal data types
  • AmcdDataType list of PowerDesigner internal
    data types mapped to DBMS data types
  • OdbcPhysDataType - translation table from ODBC
    data types to target DBMS data types
  • PhysDataType contains the translation table
    from target database data types to internal data
  • PhysDttpSize - table of storage sizes of target
    DBMS data type
  • PhysOdbcDataType contains data type
    translations from target DBMS to ODBC
  • HostDataType translation from database data
    type to procedure data type
  • Abstract translation files several files for
    abstraction data type translation
  • Customize retrieved information from
    PowerDesigner 6 DEF files

DBMS Definition File (XDB)
  • ODBC same structure as Script category. Used
    for ODBC generation when DBMS Script category
    does not suffice
  • Profile see next section
  • Trigger templates list of pre-defined trigger
    templates indicating referential integrity
  • Trigger type insert, update, delete
  • Trigger template items list of pre-defined
    trigger template items to support the
    PowerDesigner trigger templates

DBMS Definition File (XDB) - How does it all work?
  • Generation - object statements are parsed and
    their variables are evaluated and replaced.
    Script and ODBC use the same statements
  • Extension mechanism uses extension statements
    to generate additional code before or after the
    Create, Drop, or Modify statements
  • Defined using PowerDesigner Generation Template
    Language (GTL)
  • Can contain references to extended attributes,
    variables, and macros
  • Modify statements - statements used to modify
    existing objects during database modification and
    to generate DDL outside the table create
  • ModifiableAttributes list of extended
    attributes to be evaluated during the Modify
    database process
  • Database definition items
  • Statements that customize the PowerDesigner
    interface and behavior according the current
    database features

DBMS Definition File - How does it all work?
  • Reverse engineering
  • Script - Each statement in the script file maps
    to a create statement in the DBMS file
  • ReversedStatements list of Extension statements
    used in database generation
  • ODBC two distinct type of queries are used to
    retrieve information from system tables when the
    default ODBC function calls do not retrieve
    enough information
  • Extended Queries user defined queries and
    variables used when system table information is
    stored in Long, Blob, or Text columns
  • Returned field allowing this is indicated in
    query header with the "EX" indicator
  • When the "EX is found, and if the returned value
    contains a with query name and field name,
    then it will execute the appropriate query and
    use the returned value to replace the part.
  • ReversedQueries list of user-defined ODBC
    queries to be taken into account via reverse
  • Queries must be listed in ReveredQueries item to
    be executed
  • The result of a query is mapped to PowerDesigner
    internal variables via the query header

Miscellaneous Tips Change Modify SQL order
  • Problem
  • When executing Modify Database, PowerDesigner
    generates the DDL based upon statement type. All
    the drop statements, then the create statements,
    etc. However, some customers do not like this
  • Solution
  • Change the modify SQL order. To group all the SQL
    orders relative to a table in Modify script add
    the following registry key (CR 270997)
  • HKEY_CURRENT_USER\Software\Sybase\PowerDesigner
    9\FolderOptions\Physical Objects
  • "GenTablGroupStmt" "Yes"

Extended Model Definitions (XEM)
  • What
  • Mechanism for extending PowerDesigner object
  • Contains graphical, functional and generation
  • Why
  • Used by PowerDesigner engineering to support
    various functions
  • Can be used to complement object language
    generation Application servers support
  • Can be used to generate totally new text files
  • Users can customize included behavior to better
    suit your requirements
  • Users can add totally new functionality
  • How
  • General Features Guide Chapter 8 Working with
    Extended Model Definitions
  • Advanced User Documentation Chapter 2 Using
  • Advanced User Documentation Chapter 4
    Extended Model Definitions Reference Guide
  • Review included XEM files for understanding and

Extended Model Definitions (XEM)
  • Extended Model Definition properties
  • Name and Code uniquely identify this definition
  • File Name where XEM is saved, blank if internal
    to the model
  • Family Classify an XEM, usually to associate it
    with an Object Language
  • Sub Family further classification of and XEM
    within the selected family
  • Auto attach determines whether the default is
    to include this XEM in new models created
    targeting the family specified above
  • Category used to control generation options
  • Enable Trace Mode debugging/learning tool that
    lets you preview the templates used
  • Complement Language generation determines
    whether this XEM definition will be used in the
    language generation (Only available for OOM XEM

Extended Model Definitions (XEM)
  • Generation section define optional tasks to be
    processed after generation and options used
    during generation
  • Commands actual commands which will be executed
    post generation
  • Options options user can specify as part of the
    generation process
  • Tasks actual list presented during generation,
    these reference one or more commands defined
  • Profile see next section

Miscellaneous Tips - HTML Report page break
  • Problem
  • PowerDesigner implicitly cut pages every 50 rows
    for list which can be a problem for large model
  • Solution
  • Define when you want PowerDesigner to generate a
    page break in list using the following keys
  • NbRowInHtmlList - allows to define the number of
    items you want on each HTML pages generated for
    list items
  • NbSubPageInHtmlList - allows to define the number
    of links you want to have below each pages of the
  • HKEY_CURRENT_USER\Software\Sybase\PowerDesigner
  • "NbRowInHtmlList" "50" (default value)
  • "NbSubPageInHtmlList" "20" (default value)

Definition Files (XDB and XEM) Profile
  • What
  • Extension mechanism for customizing the
    PowerDesigner Metamodel.
  • Categorizing objects, customizing graphics,
    adding metadata, adding object specific
    generation options and more
  • Why
  • Used by PowerDesigner engineering in both XDB and
    XEM files
  • Allows customizing graphics based on object type
    and category
  • Customize context menus based on object type
  • Add additional metadata to specific object or
    categories of objects
  • How
  • Advanced User Documentation Chapter 2
    Managing Profiles
  • Review supplied XDB and XEM files for examples of

Definition Files (XDB and XEM) Profile
  • Shared contains extended attribute types or
    templates which can be used by any object
  • Metaclass level extensions
  • Determines the level at which the extension
  • Extensions apply to all instances of the
  • The PowerDesigner metamodel is object oriented
    and thus supports inheritance
  • Tip when adding metaclasses, change the filter
    to show abstract classes
  • Example extended attributes applied to the
    following levels would apply to
  • NamedObject - applies to all
  • ConstrainedNamedObject - applies to Columns and
  • Columns - applies to Columns only

Definition Files (XDB and XEM) Profile
  • Instance level extensions
  • Stereotype extension applies to instances of
    the object which have had the stereotype set to
  • In 9.5.x, primarily used in the PowerDesigner
  • In PowerDesigner 10 stereotypes can be used in
    the PDM as well
  • Example Java Classes EJBEntity, EJBSession,
  • Criterion extension applies to instances of the
    object which match the Criterions condition
  • Conditions are defined using expressions from the
    .if macro syntax of PowerDesigners GTL

Definition Files (XDB and XEM) Profile
  • For any of the levels listed above the following
    extensions can be added
  • Extended Attributes additional metadata which
    can be controlled by each instance and used to
    control generation
  • Custom Checks enhance the validation of
    instances when check model is performed
  • Includes check and auto-fix logic
  • Written in VBScript
  • Custom Symbol customize the visual display of
    objects to better identify the instances
  • Custom Tool (Stereotypes only) allows the
    creation of a tool palette object to ease the
    creation of objects
  • Templates and Generated files used to generate
    text files based on the model
  • Tip - F12 to find where a template is defined
  • Method and Menu These two are used to add
    entries to context menus. Method hold the
    VBScript to execute. Menu is the text that shows
    in the menu

Generation Template Language
  • What
  • PowerDesigner internal template based language
    used for text generation
  • Used in Definition files (XDB or XEM) to generate
    files based on a model
  • Why
  • Allows for all PowerDesigner generation to be
  • Used by PowerDesigner engineering to generate
    text files
  • Can be used by users to alter files generated by
    PowerDesigner to suit your individual needs
  • Can be used to generate entirely new files.

Miscellaneous TipsChanging colors in code editor
  • It is possible to customize the colors used for
    keywords, comments, etc. in the code editors (VB
    Script, Preview, SQL Editor, ...).
  • The change can be done in registry under the key
  • By default, the Controls\Editor is almost empty.
  • The keys are dynamically created once you have
    opened a syntax editor in PowerDesigner (preview,
    script, VB Script, ...).
  • You can change the syntax coloring for each type
    of file/editor (Java, SQL, C, ...).
  • For each file type, there are several category of
  • Comment, Keyword, Number, Operator, String, Text,
    Text Selection
  • For each category, you can change the foreground
    color and background color.

Miscellaneous TipsChanging colors (cont)
  • To change the text colors
  • Open the registry
  • Open the node Software\Sybase\PowerDesigner
  • Open the node of the file type, for example, SQL
  • Open the Color Groups node
  • Select a category, for example, Comment
  • Create a new DWORD entry
  • Rename the entry to Foreground
  • Change the value of the entry to BBGGRR in hexa
  • Example 0000FF (red), FF0000 (blue)

Miscellaneous Tips Test Data Generation
  • Change data format in Test data generation
  • In order to change the date format in test data
    generation, you must create new entries in XDB
  • \Script\Sql\Format\DateFormat
  • \Script\Sql\Format\TimeFormat
  • \Script\Sql\Format\DateTimeFormat
  • \Script\Sql\Format\OdbcDateFormat
  • \Script\Sql\Format\OdbcTimeFormat
  • \Script\Sql\Format\OdbcDateTimeFormat
  • For datetime(DT) or timestamp (TS) data types
  • "DateTimeFormat" is used generating by script
  • "ODBCDateTimeFormat" is used generating by ODBC.
  • For date (D) datatypes
  • "DateFormat" is used generating by script
  • "ODBCDateFormat" is used generating by ODBC

Miscellaneous TipsTest Data Generation(cont)
  • For time (T) datatypes
  • "TimeFormat" is used generating by script
  • "ODBCTimeFormat" is used generating by ODBC.
  • PowerDesigner looks at the conceptual
    correspondent data type of the physical data type
    of the column to be generated to know which DBMS
    entry to use.
  • The content of these entries will be the format
    for the date using the following formatting
  • "yyyy" represents year on 4 digits
  • "yy" represents year on 2 digits
  • "mm" represents months
  • "dd" represents days
  • "HH" represents hours
  • "MM" represents minutes
  • "SS" represents seconds

Miscellaneous Tips- Copy Symbol Format
  • Copy Symbol Format
  • Applies object formatting information from one
    object to another(line styles, color, font, )
  • Only accessible via format toolbar, or add to
    some other toolbar
  • two toolbar pieces
  • Get Format - Select source object and click
  • Apply Format - Select Target object and click

Miscellaneous Tips Mouseless Prop Nav
  • Mouseless Property Sheet Navigation
  • Ctrl - Tab - Next tab page
  • Ctrl-Shift-Tab - Previous tab page
  • Ctrl-PgUp - Next sub tab, Notes Description or
    Annotations, text area must have focus
  • Ctrl-PgDn - Previous sub tab

Miscellaneous Tips List Tips
  • List tips
  • Customize Columns and Filters button in toolbar -
    add or remove displayed columns
  • Multi-select to make same change to many objects
  • Ctrl-Up - First line in list
  • Ctrl - Down - Last line in list
  • Ctrl - Left - First column on row
  • Ctrl - Right - Last column on row

Miscellaneous Tips Mouse Roller Support
  • Mouse Roller Support
  • roll up scroll to top
  • roll down scroll to bottom
  • shiftroll up scroll left
  • shiftroll down scroll right
  • ctrlroll up zoom-in and center the view to the
    position of the mouse
  • ctrlroll down zoom-out and center the view to
    the position of the mouse
