Smart Studio

Revision as of 15:34, 10 September 2020 by NWE (Talk | contribs)

With UBIK® Smart Studio, project engineering is made easier: Smart Modelling means to build meta models, do programmatic customizing and ACM configurations without having to work all the repetitive details. UBIK® Smart Modelling automates as much as it can in order to give the engineer leeway to actually do the project.

On the Augmensys [release portal], a test candidate for the beta version of UBIK® Smart Studio is available. Here's the history of recent changes: Smart Studio Beta History

UBIK® Smart Studio


Usage

UBIK® SmartStudio is designed as an integrated developer environment (IDE) and administration tool. With UBIK® SmartStudio, you can work on a project and transport the results, and you can interact with a UBIK® Environment (data base, web services, etc.). Also, you can import meta definitions from external files (e.g., from Excel worksheets describing a customer's entities).

The central use-cases for UBIK® SmartStudio are modelling and transportation. Modelling means to build up a new UBIK® meta model, objects and customizing, or to maintain and develop an existing project. Transportation means to get UBIK® meta data, objects and customizing from one place to another. This includes import from external systems or files, extraction from an existing UBIK® Environment, and integrating UBIK® meta definitions, objects and customizing into a new or existing UBIK® Environment.

In order to support these use-cases optimally, UBIK® SmartStudio provides modelling and transportation tools as well as sophisticated mechanisms for aiding your work: By automating as much as possible, UBIK® SmartStudio helps preventing mistakes, ensuring consistency, minimizing unnecessary and tedious effort, and enabling you to concentrate on what you really want to do.

Basic handling idea

Assuming a modelling use-case, you might want to define the meta model for a project. You launch UBIK® SmartStudio and create a new Smart Project. To start working, you open the Inheritance Graph using the menu.

In the middle of the screen, there is a worksheet that can be used to draw the project structure on. Add new or existing models by dragging them from the pickers on the left of the screen to the worksheet area in the middle. Connect the models using lines in order to define the models' dependencies on each other. When a model is selected, it can be edited using inspector tools on the right of the screen.

The first step when using UBIK® Smart Studio always is to open a project (or create a new one). Then you can open an existing worksheet or create a new one and start modelling. Later, you can save your models to the project. Independent on the project, you can punctually save the current state of a worksheet (its "Situation") to the UBIK® environment (database), if it is connected.

Organizing your work

In order to organize your work and to separate modelling from working directly on the (productive) system, there are Smart Projects. They serve as a container for your work, giving you the possibility to punctually interact with UBIK® Environments (databases). This allows the user to transport (and re-use) smart models between different UBIK® Environments.

Transport Container

Sometimes, you don't want to design a data model but instead take it from one UBIK® Environment to another, or to control in detail what you want to save to a target UBIK® Environment. This is what the Transport Container is for. This worksheet (like the project view) features a Situation Editor giving you a detailed overview about the models it contains as well as the possibility to add or remove models, and to select a subset of the contained models and do something with it (e.g., retain only the selected models).

Inheritance Graph

There are multiple kinds of modelling worksheets with different responsibilities: The Inheritance Graph allows the user to create meta models. It's called "Inheritance Graph" because the MetaClasses' inheritance structure is displayed graphically.

Meta Classes

You can drop existing meta classes onto the graph in order to see the full inheritance hierarchy, classifications and meta properties. You can also drop a new meta class from the tool box picker, and proceed to model it by dropping meta properties onto it, or connecting it to other meta classes to establish an inheritance hierarchy.

Meta Properties

The details of meta properties can be configured in the inspector tool for a selected meta property. The options include data type, selective list, unit, multi language, etc. Live value meta properties are supported, too.

Classification

It is also possible to specify classifications for meta classes by dropping the classification onto the graph and then connecting it to the respective meta class. Classifications are not implemented immediately to prevent undesired changes. Select the connection between the classification and the meta class, and toggle the "implement classification" checkbox in the inspector tool for the connection, in order to add the classification's meta properties to the meta class. Classifications can be designed just as meta classes, but inheritance of classifications is currently not supported.

Relations

Relations can be designed in the relation editor (by just connecting two instances and configuring the details on the connection), or in the application graph for scoped connections. See the respective chapter for the relation instance graph.

Proxies

Proxies can be designed in the proxy graph, which is very similar to the inheritance graph. You can use a context menu command to open the proxy graph for a meta class, if a proxy exists. Create a new proxy by dropping a meta class onto the proxy graph. See the respective chapter for the meta proxy graph.



Application Graph

The Application Graph can be used to define what the user can see on the mobile device. It's called "Application Graph" because the browsing hierarchy for the mobile application is displayed graphically. One can define specific mobile versions of MetaClasses (namely Scopes) as well as their properties and children with it.

App and Context

You can create or reuse app and context objects to identify the view providing data to your satellites. Below a context, you can model the view hierarchy graphically using scopes and connections between them. The context can be configured with input queries for the root and infrastructure objects. Just drag a query onto the graph and connect it to the context's respective input connector.

Scopes

A scope specifies what properties for instances of a meta class will be delivered to the satellite. E.g., for pumps we might have many properties in the data base, but on the client, we require only two of them - this can be specified using meta class scopes. You can specify whether it should be possible to create or delete instances on the scope. However, you can also use query scopes to provide an interface to a query object on the client. In order to create a query scope, hold Shift) while dragging a query onto the graph. Drop meta properties on a scoped query in order to provide access to the query's properties and query items. Meta query scopes are supported as well; dropping a query meta class on the graph will result in a respective scope.

Connections

In the app graph, scopes can be connected hierarchically, in order to specify: "As children for scope-A-objects, I want to see scope-B-objects". Further, you can configure how the children should be resolved for a scoped connection - should a relation be used, or a link property on a child pointing to the parent object? For query scopes, the outgoing connections are a bit simpler, because they can only target scopes that are compatible with the query filter class, and since the query delivers the children, there isn't much to configure there. For meta query scopes, no outgoing connections are shown because we cannot anticipate what query will be used at design time. However, if you provide a fitting child scope to the context, it will be used for the children of queries.



Bulk Editor

In order to modify potentially larger amounts of content instances conveniently, the Bulk Editor can be used. It shows all instances of a MetaClass in a table, extendable by derivates. The table rows are the instances, whereas the columns describe the meta properties. A single cell corresponds to the property value of a specific instance for a MetaProperty. As every other worksheet, the bulk editor can be used with data from a UBIK® Environment. The results can be saved into the active project and/or back into the UBIK® Environment. The Bulk Editor supports multi-language values, sorting, filtering, grouping, drag & drop (also for multiple rows) and copy & paste (also for multiple target cells). Also, for the Bulk Editor, a multi-instance editor tool is available (similar to the inspector tool), allowing you to edit the values for multiple selected instances. A Bulk Editor worksheet can be exported to Excel using the respective context menu item.

Designing Queries

Queries can be designed using the Bulk Editor. You can use the context menu command "Convert to Query" in order to create a query for the meta class the bulk editor currently shows instances for. Then you can add Query Items by holding the Shift key while dragging column headers onto the query on the top left. The query items appear next to the query and can then be configured.



Relation Target Bulk Editor

The Bulk Editor can also be used to bulk-edit the objects related to an instance via a relation. This can be achieved by selecting any instance and using the context menu item "Bulk-edit relations" (respectively, a sub-menu item for a specific relation or reverse-relation). In this case, the items displayed in the Bulk Editor correspond to all instances related to the formerly selected instance via the chosen relation. The Bulk Editor then can be used to relate existing instances via drag & drop, to create and relate new instances, to un-relate instances, and of course to (bulk) edit the related instances just as you would with a "normal" Bulk Editor.

Relation Instance Graph

Relational connections between content instances can be modelled using the Relation Instance Graph. Drop an instance on it in order to see relations and references to other instances. New references and relations can be created; existing relations can be edited. It is also possible to load the reverse references and relations (i.e., instances referring or related to the target instance) via context command.

Meta Proxy Graph

MetaProxies, their properties and their inheritance can be modeled and edited in the Meta Proxy Graph. A picker displaying all MetaProxies in the project and the UBIK® Environment is available for choosing elements to display in the Meta Proxy Graph worksheet.

Project Model Import Worksheet

Sometimes it can be handy for a project engineer to let the customer fill in an Excel sheet listing all the MetaClasses and MetaProperties. The engineer then can extend the Excel configuration with details, including MetaProxies and ACM scope configurations. This Excel map can be imported by SmartStudio, using the Excel/OleDB Project Model Import Worksheet. The result of this import can be saved into the active project or the UBIK® Environment, and inspected in various other worksheets if desired. An important feature of this import worksheet is the configuration of column mappings (assignment of column names or indexes to something meaningful in UBIK, like the name of a MetaClass) and the automatic detection of erroneous column assignments.

Here's an example for an Excel map that can be imported: SmartStudio Excel Project Import Test Map.zip


Smart Projects

Smart Projects are containers for Smart Modelling data. A Smart Project contains worksheets and Smart Models and is stored in a file with the extension "*.smp". Projects are independent from UBIK® Environments, per se. That allows the user to transport and re-use smart models in different UBIK® Environments. Also, a project can be designed "offline" without working on an actual productive system. Only one project can be opened at a time. A project must be opened in order to create worksheets.

UBIK® Smart Studio Projects

Start page

After opening UBIK® Smart Studio, the Start page is available. It shows recently used project and UBIK Environment connections (database connections). It can also be used to open or create Smart Projects.

Project page

Once a project is opened, there is a project page listing all the work sheets (e.g., Inheritance Graphs or Application Graphs) as well as a Situation Editor giving you a detailed overview about the models it contains as well as the possibility to add or remove models, and to select a subset of the contained models and do something with it (e.g., retain only the selected models). You can save a currently selected project using Ctrl + S or the save symbol in the tool bar. However, make sure all the worksheets are saved to the project so you don't lose any data. This two-stage saving might seem unpractical at first, but there will be the situation where you don't want to save a worksheet to the project, so the ability to choose which worksheet to save is necessary. You can also remove worksheets and even single models from the project on the project page, by the way.

Worksheets

Worksheets like the Inheritance Graph or the Application Graph can be used to edit a part of the project. E.g., there could be two Inheritance Graph worksheets, each containing only a subset of the whole project. For example, you could model Pump meta classes on one worksheet and model Valve meta classes on another worksheet. Of course, you can also have a worksheet showing all the models at once, if you prefer it that way.

Adding models to a worksheet

Models can be selected and added to worksheets using Smart Studio's object pickers (the filterable, searchable and sortable list views to the left of the IDE), simply by dragging a model over to a worksheet and dropping it there. Alternatively, the Object Finder can be used to find and insert models into a worksheet.

It is important to know that models can either originate from the connected UBIK® Environment (database) or from the currently active project. We call that the "Source" of the model. Models from the project will always have a dashed border, whereas models from the UBIK® Environment always have a solid border.

You can remove models from the project (and all its worksheets) on the project page, or directly from a single worksheet. In a worksheet, you can choose the source (project or environment) for a model. As a consequence, its details and dependencies will be updated and the model will be marked with the symbol for its source.

Saving Worksheets

Worksheets can be saved either to the connected UBIK® Environment or to the currently active project.

Saving Worksheets to the Project

You can save an active worksheet to the project using the confirm button (the icon is a hook/check symbol) in the tool bar, or using the "Save to Project" context menu item. This doesn't save the worksheet to the connected UBIK® Environment. As soon as you save a worksheet to the project, all affected models in the saved worksheet will be marked as project models. After saving the worksheet, the project will be marked as changed and can be saved using Ctrl + S or the save symbol in the tool bar, when the project page is selected.

A project can have multiple worksheets with overlapping content (i.e., models that exist in multiple worksheets). Changing a worksheet can affect other worksheets after saving the change in order to keep consistency (this happens automatically): the worksheet content is propagated to all other worksheets (and to the project), so that your project situation is consistent.

Saving Worksheets to the UBIK® Environment

You can save an active worksheet to the currently connected UBIK® Environment busing the "Save to UBIK® Environment" toolbar button or context menu item. This doesn't save the worksheet to the project. The worksheet content will be saved to the database and the results will be shown in a new worksheet. Smart Studio's object pickers will be updated with the new models.

Merging Worksheets

Worksheets can originate from an import, from the project or from the environment. Wherever it might have came from, you can save the worksheet content to either the project or the environment. However, in some cases the worksheet content needs to be combined with what you already have in order to resolve conflicts.

Merging worksheets with the UBIK® Environment

It is possible to merge a worksheet with the Environment (UBIK® database). The result is a combination between what you have defined in your worksheet and what the environment contains already regarding that situation. In case of a conflict, normally the environment "wins". E.g., if you have a meta class A deriving from another meta class B in your worksheet, but the environment specifies C as a parent of A, the result of a merge would be A deriving from C. Using the inspector, you can specify whether a worksheet should override the environment on a merge. In that case, the merge result from the example above would be A deriving from B.

The result of such a merge is not saved yet; you can edit it and decide what to do with it - e.g., save it to the project, save it to the environment or dismiss it.

Merging worksheets with the SmartStudio project

You can also merge a worksheet with the currently active project, without saving it. The result is a combination between what you have defined in your worksheet and what the project contains already regarding that situation, In case of a conflict, normally the project "wins". E.g., if you have a meta class A deriving from another meta class B in your worksheet, but the project specifies C as a parent of A, the result of a merge would be A deriving from C. Using the inspector, you can specify whether a worksheet should override the project on a merge. In that case, the merge result from the example above would be A deriving from B.

The result of such a merge is not saved yet; you can edit it and decide what to do with it - e.g., save it to the project, save it to the environment or dismiss it.

Cancelling active tasks

Some operations can take a while, for example when a lot of data is loaded into a worksheet. Such tasks can be canceled using the stop symbol in the toolbar or Esc.

UBIK® Environment

Once a UBIK® Environment is connected, the Smart Studio's object pickers provide all the models from the environment. These models can be used in work sheets. Worksheet situations can be saved to the UBIK® Environment that is currently connected. Only one UBIK® Environment can be connected at a time.

Environment Page

There is an Environment page for publishing ACM and programmatic customizing as well; it can be accessed using the Start page or the menu, if a UBIK® Environment is connected.

It provides the following sub-sections for controlling the UBIK® environment; Customizing and Application.

Customizing

The Customizing sub-section allows to check and deploy the programmatic customizing for the active environment (not project-related). It consists of a view for showing the custom code and several commands for checking, compiling and deploying it.

The following commands are available:

  • Assemble custom code from the MetaClasses (using the menu button or F5)
  • Check the custom code for syntax errors (using the menu button or F6)
  • Compile & deploy the customizing locally (using the menu button or F7)
  • Deploy the previously compiled customizing to the server (using the menu button or F8).

All commands depend on the previous commands (in the above order), for safety reasons.

Application

The Application sub-section allows to check and deploy the ACM Meta Definitions for the active environment (not project-related). More precisely, the Meta Definitions for a specific Context can be managed, which means that you have to select an Application's Context before you can do anything.

The sub-section consists of a selection area, where you can specify the Context to be managed - drag & drop an Application object into the selection area in order to show the available Contexts. Also, there is a view showing the assembled Meta Definitions as XML for inspection. There are commands available for assembling and deploying the Meta Definitions.

The following commands are available:

  • Assemble all Meta Definitions for the selected Context (using the menu button or F9)
  • Deploy the previously assembled Meta Definitions to all UBIK® satellites via the web services (using the menu button or F10) - don't forget to restart the web services to make sure the changes are applied correctly!

All commands depend on the previous commands (in the above order), for safety reasons.


IDE

The IDE of UBIK® Smart Studio was greatly inspired by Microsoft Visual Studio and similar development environments. This means that well-known and proven concepts, such as free docking of Tools, Documents and Controls is supported by Smart Studio and it's following the same usability principles.

Options

UBIK® Smart Studio features a centralized Options center where all installed modules inject their configuration settings. By default, this can be reached through Tools → Options, or, if the respective module supports it, from the context-menu of the module.

Tools

UBIK® Smart Studio provides the following tools:

Pickers

Pickers are meant to provide certain objects for usage in other controls, so they mainly server as a Drag&Drop source during the engineering process.

Picker Types to pick Target controls
Class Picker MetaClasses Inheritance Graph, Application Graph, Inspector
Property Picker MetaProperties Inheritance Graph, Application Graph, Inspector
Classification Picker Classifications Inheritance Graph, Application Graph
ACM Picker Applications and Contexts Application Graph, Environment View
Selective Lists Selective Lists Inheritance Graph, Inspector
Query Picker Queries Inheritance Graph, Application Graph, Inspector
Unit Picker Unit Items Inheritance Graph, Inspector
Workflow Picker Workflows Snippet Editor
RelationPicker Relations Inspector

Object Finder

The Object Finder is a tool for finding and using MetaClasses and Instances in your worksheets.

Error List

The Error List module shows notifications in the following categories

Category Meaning
Error Errors that occurred in the UBIK® core or in the IDE of Smart Studio; should be reported to Support in any case!
Warning Warnings that occurred in the UBIK® core or in the IDE of Smart Studio; typically not critical for the operation of UBIK®
Message Informational messages
Database Messages from the UBIK® data layer
Service Messages from the UBIK® Web Services
Workflow Messages from the UBIK® Workflow Engine
Custom Messages generated by customizing code

Output

The Output tool shows debug and error messages in plain text format.

Immediate Window

The Immediate Window allows for scripting of C# code on the fly, without compilation; evaluation of the script happens as soon as the KeyPress key is pressed, but statements are also cumulative. This means that if e.g. the line var a = SUIS.SelectedObject is executed, the variable a is preserved for all subsequent statements and can therefore be used in the next lines; so the following statement a.Name will deliver a correct value.
