Enterprise Architect User Guide provides tutorials, guidance and reference material to help you use Enterprise Architect in: Modeling With Enterprise Architect Model Management Project Management Model Auditing Model Baselining and Differencing Model User Security Model Version Control Code Engineering Visualization and Analysis of Code Execution RTF and HTML Document Creation (Reports)

If you are new to modeling and UML as well as Enterprise Architect, or otherwise want a rapid review of the process of modeling with Enterprise Architect, go to the Quickstart Tutorial.

Baseline Diagram Comparison Conduct a visual diagram comparison between your current diagram and a previous baseline .

Personal Information Window See how the Personal Information Window in Enterprise Architect can help you organize your daily tasks and workflow.

Working Sets As you perform work on your model, you open various windows, diagrams and views. Working Sets allow you to return to these same views in a later work session.

Business Rules A car rental system is used to illustrate how to generate executable business rules using Enterprise Architect.

EJB MDG Technology for Enterprise Java Beans allows the user to model EJB entities and EJB sessions, complete with UML profiles for modeling EJB, EJB patterns and Code Management. (requires Enterprise Architect 4.1 or later)

ICONIX AGILE DDT ICONIX Agile Developer - Design-Driven Testing (DDT) streamlines the ICONIX modeling process, providing: Convenient modeling of robustness diagrams Automatic generation of sequence diagram structures from robustness diagrams Transformation of robustness control elements to test diagrams Transformation of sequence diagram elements to test diagrams Transformation of requirement diagrams to test diagrams Transformation between test cases and test classes. (JUnit & NUnit) Built-in model validation rules for ICONIX robustness diagrams (requires Enterprise Architect 7.5 or later)

Testing MDG Technology for Testing helps users to rapidly model a wide range of testing procedures including component testing, SUT, Test Cases and more. (requires Enterprise Architect 4.1 or later)

Instructions for loading an MDG Technology EXE file: Download and run the .exe file to install the MDG technology. Open Enterprise Architect. Select from the Main Menu Add-Ins | XYZ Technology | Load.

Built-in MDG Technologies: Most of the MDG Technologies provided by Sparx Systems are built into Enterprise Architect directly. Depending on your edition of Enterprise Architect, some or all of the following MDG Technologies will be available:

Gang of Four Patterns

Mind Mapping

Web Modeling

Data Flow (DFD)

Entity-Relationship (ERD)

Business Rule Model

BPMN™

XSDDataTypes Package: This package contains classes representing XSD primitive data types. This package is available as an XMI file. To import the file as a UML Package, use EA's XMI import facility which is available from the menu item: Project | Import/Export | Import Package from XMI. UML Profile for XML: This resource file contains the stereotyped classes which allow the schema generation to be customized. The UML Profile for XML can be imported into a model using the Resource View (see Importing Profiles for details on importing UML profiles into EA).

Steps to Generate XSD: Select the package to be converted to XSD by right-clicking on the package in the Project Browser. Select Project | Generate XML Schema from the main menu. Set the desired output file using the Filename field. Set the desired xml encoding using the Encoding field. Click on the Generate button to generate the schema. The progress of the schema generator will be shown in the Progress edit box.

Individuals: instances or objects

Attributes: aspects, properties, features, characteristics, or parameters

Relations: ways in which classes and individuals can be related to one another

Function terms:

Restrictions: formally stated descriptions of what must be true in order for some assertion to be accepted as input

Rules: statements in the form of an if-then (antecedent-consequent) sentence that describe the logical inferences that can be drawn from an assertion in a particular form

Axioms: assertions (including rules) in a logical form

Events: the changing of attributes or relations

In an EAV data model, each attribute-value pair is a fact describing an entity, and a row in an EAV table stores a single fact

EAV tables are often described as "long and skinny": "long" refers to the number of rows, "skinny" to the few columns

Data is recorded as three columns: The entity: the item being described. The attribute or parameter: a foreign key into a table of attribute definitions. At the very least, the attribute definitions table would contain the following columns: an attribute ID, attribute name, description, data type, and columns assisting input validation

The value of the attribute

Row modeling, where facts about something (in this case, a sales transaction) are recorded as multiple rows rather than multiple columns

differences between row modeling and EAV (which may be considered a generalization of row-modeling) are:

A row-modeled table is homogeneous in the facts that it describes

The data type of the value column/s in a row-modeled table is pre-determined by the nature of the facts it records. By contrast, in an EAV table, the conceptual data type of a value in a particular row depend on the attribute in that row

In the EAV table itself, this is just an attribute ID, a foreign key into an Attribute Definitions table

The Attribute

The Value

Coercing all values into strings

larger systems use separate EAV tables for each data type (including binary large objects, "BLOBS"), with the metadata for a given attribute identifying the EAV table in which its data will be stored

Where an EAV system is implemented through RDF, the RDF Schema language may conveniently be used to express such metadata

access to metadata must be restricted, and an audit trail of accesses and changes put into place to deal with situations where multiple individuals have metadata access

quality of the annotation and documentation within the metadata (i.e., the narrative/explanatory text in the descriptive columns of the metadata sub-schema) must be much higher, in order to facilitate understanding by various members of the development team.

Attribute metadata

Validation metadata include data type, range of permissible values or membership in a set of values, regular expression match, default value, and whether the value is permitted to be null

Presentation metadata: how the attribute is to be displayed to the user

Grouping metadata: Attributes are typically presented as part of a higher-order group, e.g., a specialty-specific form. Grouping metadata includes information such as the order in which attributes are presented

JDBC Templates hardly give any abstraction on top of the database and you’re on your own for Object Relational Mapping. We strongly advise to use JPA wherever possible; it gives portability by abstracting most of the database specific SQL that you would need, and it does all the hard and painful work of object mapping

small part of your application

In general, JDBC Templates are a poor solution. They don’t have enough abstraction to work on different databases because you use plain SQL in queries. There is also no real ORM mapping which results in quite a lot of boilerplate code
