Logic model - attribute of the entity?

• Calculation of sum in the attribute of the entity

  Dear all,
  
  I have following the entity attr.

  <Attribute
      Name="TotalAppraisedIncome"
      ColumnName="TOTAL_APPRAISED_INCOME"
      SQLType="NUMERIC"
      Type="oracle.jbo.domain.Number"
      ColumnType="NUMBER"
      TableName="z_z"
      IsQueriable="false"
      RetrievedOnUpdate="true"
      RetrievedOnInsert="true">
      <DesignTime>
        <Attr Name="_DisplaySize" Value="22"/>
      </DesignTime>
      <TransientExpression><![CDATA[adf.object.IncomeDetailSummary_VO1.sum("(AppraisedIncome/100)*IncomeCombination")]]></TransientExpression>
    </Attribute>

  The problem is that it does not display the design for attribute value, betai I created the accessor to view in the attribute of the entity.
  
  But when I use it in viewobject as transitional attribute, it works very well...

  <ViewAttribute
      Name="TotalAppraisedIncomeView"
      IsSelected="false"
      IsPersistent="false"
      PrecisionRule="true"
      Type="oracle.jbo.domain.Number"
      ColumnType="NUMBER"
      AliasName="VIEW_ATTR"
      SQLType="NUMERIC">
      <RecalcCondition><![CDATA[true]]></RecalcCondition>
      <TransientExpression><![CDATA[IncomeDetailSummary_VO1.getRowSet().sum("(AppraisedIncome/100)*IncomeCombination")]]></TransientExpression>
    </ViewAttribute>

  I need to do at the level of the entities because the value is caluclated runtime and it should be updated in the field of database corrosponding.
  
  Any ideas?

  Hello

  but the problem continues (even when the model is reduced to no entity at all!)

  The error that you stated (in engineering and import) is not reached, if there is none of the entities and attributes - this is a specific error, probably in connection with the use of separate types that are removed from the design.

  You can use the search feature to find attributes/columns (logical/relational model) with incorrect data type definition based on the separate type.

  And it is better to move it to Data Modeler 4.0 (833).

  What to look for (example on the logic model - it is the same for the relational model - column):

  (1) to activate the search engine (CTRL-F when logical diagram is active, or the Find icon), switch to advanced mode

  (2) for the attribute "object Type":

  -check the 'Kind of Data Type' line and put DT as search text

  -check the 'Distinct type' line, do not put the text search - it will search attributes without separate type

  -change the operand of OR AND expression

  3) press the ' search ' button.

  If you find some attributes, then you will need to decide what to do with them - to define the data type or delete.

  Ditto for the columns in the relational model.

• Get a NAMED check constraint when the entity attribute derived from the field

  I'm designing a new database and beginning with a logic model of the ER. I've defined several areas, such as the NO_YES field (with values of ' no and 'Y'). When I use this area as a data type of an attribute of the entity (for example, the CHANGE_REQUEST.IS_APPROVED attribute), I also specify a constraint name (for example, CR_APPROVED_CK) of the attribute (this is done in the Group of constraint, property name constraint and the properties of the attribute dialog box, default value).
  
  When I have the logic model to a relational model of the engineer, the constraint name is lost. Specifically, for the definition of the table that is created, for the column in question, in the default column properties and constraints Panel dialog box, the name of constraint property is empty. When I generated the DDL of the relational model, the check constraint that is generated is an inline check constraint (such as ' IS_APPROVED VARCHAR2 (1) CHECK (IS_APPROVED IN ('n', 'Y')) '). When this DDL is executed to generate database objects, the created check constraint has a system-generated name. I want the constraint to have a name that I create.
  
  By experimentation, I found that in the relational model, if I specify a value for the property name of the constraint in the DOF resulting constraint get named (an ALTER TABLE statement is generated that contains "ADD CONSTRAINT CR_APPROVED_CK CHECK (IS_APPROVED IN ('n', 'Y'))"). However, I have redundantly change the relational model in the same way that I edited the logic model to specify the constraint names.
  
  Is there a way to guarantee that the constraint names defined in a logic model transferred during the engineering of a logic model to a physical model.
  
  The version of the Data Modeler I use is 3.0.0.665.

• Impacts on the performance of the attributes from the features of data model design

  I'm trying to understand the implications of the performance of two possible data model design.
  
  Here is my structure of the entity:
  
  Global > person > account > option
  
  Generally, when running, I instantiated a person, a single accountand five option's .
  
  There are various amounts determined according to the age of the person who should be assigned to the correct option.
  
  Here are my two designs:
  
  Design a
  
  attributes on the entity of the person :
  age of the person
  its option 1 amount
  its option 2 amount
  its option 3 amount
  its option quantity 4
  its option 5 amount
  
  attributes on the option endity:
  amount of the option
  
  support table rules:
  option = amount
  its option 1 amount if the option is number 1
  its option 2 amount if the option number 2
  its option 3 amount if the option number 3
  its 4 option amount if the option is number 4
  its option 5 amount if the option is number 5
  
  Two design
  
  attributes on the entity of the person :
  age of the person
  
  attributes on the entity of the option :
  amount of the option
  of the option option 1 amount
  of the option option 2 amount
  of the option option 3 amount
  of the option quantity 4
  of the option option 5 amount
  
  support table rules:
  option = amount
  of the option option 1 amount if the option is number 1
  option 2 amount option if the option number 2
  of the option option 3 amount if the option number 3
  the option amount 4 If the option is number 4
  option 5 option amount if the option is number 5
  
  Given two models, I can see what looks like an advantage for a design that, when running, you have less attributes (6 on retirement member + 1 on each of the 5 options = 11) as two Design (1 on retirement members + 6 on each of the 5 options = 31), but I'm not sure. An advantage to design two might be that the algorithm must do less through the structure of the entity: the table of rules support everything for the amount of the option option.
  
  Anyway there is a table of rules to determine the amounts:
  
  Design a
  its option 1 amount =
  2 if age = 10
  5 if age = 11
  7 if age = 12, etc..
  
  Design two
  of the option option 1 amount =
  2 if age = 10
  5 if age = 11
  7 if age = 12, etc..
  
  Here, it seems that the one would have to cross over the structure of the entity for the design of two.
  
  The design will have a better performance with a large amount of rules, or it would make a difference at all?

  Hello!

  In our experience, just think about this kind of stuff if you were dealing with 100's or 1000 instances (usually through ODS). You have a very low number, the differences will be negligible, as you should (in general) go with the solution that is most similar to the material of origin or the understanding of the business user. Also, I guess that's an OWD project? Which may be even better, the inference is performed gradually when new data are added to the modules, rather than in a 'big bang' as ODS.

  It seems that the model 1 is the easiest to understand and explain. I wonder why you have the option at all entity, because it seems to be a relationship to one? If the person cannot have only a single amount of option 1, option 2 amount etc, and there's only ever going to be (up to) 5 options... is this assumption correct? If so, you can keep just like the attributes at the level of the person without the need for bodies. If there are other requirements of an instance of the option then, of course, use them, but given the information here, the option feature doesn't seem to be necessary. It would be the fastest of all :-)

  Whatever it is, that the number of instances is so low, you should have nothing to fear in terms of performance.

  I hope this helps! Write back if you have more info / questions.
  See you soon,.

• Create a concatenated string of attributes on Multiple Instances of the entity

  Hello world

  I wonder if someone has met this challenge, or ideas. We have been asked if OPA could produce a string containing the concatenation of the values of an attribute of text stored on multiple instances of an entity. The number of instances is variable, generally.

  Example: Assume that the attribute is "DayOfWeek", and we have an entity called "Appointment", with the authorities:

  appointment_1 (DayOfWeek = 'Monday')

  appointment_2 (DayOfWeek = 'Thursday')

  appointment_3 (DayOfWeek = 'Sunday')

  ... we need produce a string "AllAppointmentDays" = "on Monday, Thursday, Sunday.

  We don't think that this is possible without either: (a) an external system to generate the resulting concatenated string of the output, or (b) modules with the command of the approach to read the white paper Oracle in Nov 2012 (approaches to limits, thresholds and preferences), combined with hard-coding and the constraints on the length of the string.

  
  

  I was wondering if there was a better way to do it without external script or forced / hardcode.

  Thank you

  -Patrick

  I don' t know that an external implementation would be easier, but it could be more effective if well written.  Internal or external, you must decide how you want to classify or ordering entities before concatenation.  The order must be absolute (i.e. without fasteners).  Policies to 'solve' the first entity out of string and the string output of the policy to concatenate a string to produce this entity = the entity 'before' + ', ' + attribute of the entity are fairly simple.

  I guess the answer is: it is not necessarily a better way to do it in OPM and I don't think that there are constraints, or a more effective solution is necessary unless you already know you will work with a very large number of entities or very long strings.

• can we create specific diagrams of logic model for the relational model?

  Hi-
  
  I created several diagrams of relational model. I want to create the logical data model diagram for each of the relational model.
  Is it possible to do?
  
  Currently, it is always associated with a logical data model diagram. When I create LD for the 2nd, it is always update the same diagram.
  Please let me know.

  Beginner question here, sorry if it was taken already.
  
  In the logic model in Data Modeler, how can I change an attribute name that is used as a 'UID relationship'?
  
  For example, I create two entities, each with a primary UID called 'id', then create a 1:1 relationship. Each entity will now have an attribute called "id1" marked as a UID of Relation, but I can't find any way to change the name of the attribute. Is there a way?

  You can check the setting in the preferences - "Data Modeler > model > logic" - the name FK attribute synchronization - clear the check box if you want to manually set the name.

• Entity displayed in the browser, but not displayed in the logic model

  Hello

  In a drawing, I got myself in a situation where two entities are identified in the logic model of the browser, but are not as on the logical schema. I have created the entities, but removed later. However, when I engineer the logic of the relational model, two tables based on the entities are created. I do something wrong, or is this a bug, entities having not correctly deleted for some reason any?

  Kind regards.

  John.

  Hi John,.

  There is a problem in version 4.1.1 of maker of data if some entities or other objects are deleted from a template that has already been registered.  On the next saved position, the saved definition only is not updated correctly, and deleted items reappear on the loading of this registered version.

  This will be addressed in the next version.

  In the meantime, the workaround is to use save them as rather Save to save your template.
