-^^^^^^^^^^^^^^^
-
-Introduction
-------------
- .. container:: paragraph
-
- Consider a scenario where a supermarket chain called
- *HyperM* controls how it sells items in a policy-based
- manner. Each time an item is processed by *HyperM*'s
- point-of-sale (PoS) system an event is generated and
- published about that item of stock being sold. This event
- can then be used to update stock levels, etc..
-
- .. container:: paragraph
-
- *HyperM* want to extend this approach to allow some checks
- to be performed before the sale can be completed. This can
- be achieved by requesting a policy-controlled decision as
- each item is processed by for sale by each PoS system. The
- decision process is integrated with *HyperM*'s other IT
- systems that manage stock control, sourcing and purchasing,
- personnel systems, etc.
-
- .. container:: paragraph
-
- In this document we will show how APEX and APEX Policies can
- be used to achieve this, starting with a simple policy,
- building up to more complicated policy that demonstrates the
- features of APEX.
-
-Data Models
------------
-
-Sales Input Event
-#################
-
- .. container:: paragraph
-
- Each time a PoS system processes a sales item an event
- with the following format is emitted:
-
- .. table:: Table 1. Sale Input Event
-
- +----------------------+----------------------+-----------------------+
- | Event | Fields | Description |
- +======================+======================+=======================+
- | SALE_INPUT | time, sale_ID, | Event indicating a |
- | | amount, item_ID, | sale of an item is |
- | | quantity, | occurring |
- | | assistant_ID, | |
- | | branch_ID, notes, …​ | |
- +----------------------+----------------------+-----------------------+
-
- .. container:: paragraph
-
- In each ``SALE_INPUT`` event the ``sale_ID`` field is a
- unique ID generated by the PoS system. A timestamp for
- the event is stored in the ``time`` field. The ``amount``
- field refers to the value of the item(s) to be sold (in
- cents). The ``item_ID`` field is a unique identifier for
- each item type, and can be used to retrieve more
- information about the item from *HyperM*'s stock control
- system. The ``quantity`` field refers to the quantity of
- the item to be sold. The ``assistant_ID`` field is a
- unique identifier for the PoS operator, and can be used
- to retrieve more information about the operator from the
- *HyperM*'s personnel system. Since *HyperM* has many
- branches the ``branch_ID`` identifies the shop. The
- ``notes`` field contains arbitrary notes about the sale.
-
-Sales Decision Event
-####################
-
- .. container:: paragraph
-
- After a ``SALE_INPUT`` event is emitted by the PoS system
- *HyperM*'s policy-based controlled sales checking system
- emits a Sale Authorization Event indicating whether the
- sale is authorized or denied. The PoS system can then
- listen for this event before continuing with the sale.
-
- .. table:: Table 2. Sale Authorisation Event
-
- +----------------------+----------------------+-----------------------+
- | Event | Fields | Description |
- +======================+======================+=======================+
- | SALE_AUTH | sale_ID, time, | Event indicating a |
- | | authorized, amount, | sale of an item is |
- | | item_ID, quantity, | authorized or denied |
- | | assistant_ID, | |
- | | branch_ID, notes, | |
- | | message…​ | |
- +----------------------+----------------------+-----------------------+
-
- .. container:: paragraph
-
- In each ``SALE_AUTH`` event the ``sale_ID`` field is
- copied from the ``SALE_INPUT`` event that trigger the
- decision request. The ``SALE_AUTH`` event is also
- timestamped using the ``time`` field, and a field called
- ``authorised`` is set to ``true`` or ``false`` depending
- on whether the sale is authorized or denied. The
- ``message`` field carries an optional message about why a
- sale was not authorized. The other fields from the
- ``SALE_INPUT`` event are also included for completeness.
-
-Stock Control: Items
-####################
-
- .. container:: paragraph
-
- *HyperM* maintains information about each item for sale
- in a database table called ``ITEMS``.
-
- .. table:: Table 3. Items Database
-
- +----------------------+----------------------+-----------------------+
- | Table | Fields | Description |
- +======================+======================+=======================+
- | ITEMS | item_ID, | Database table |
- | | description, | describing each item |
- | | cost_price, barcode, | for sale |
- | | supplier_ID, | |
- | | category, …​ | |
- +----------------------+----------------------+-----------------------+
-
- .. container:: paragraph
-
- The database table ``ITEMS`` has a row for each items
- that *HyperM* sells. Each item is identified by an
- ``item_ID`` value. The ``description`` field stores a
- description of the item. The cost price of the item is
- given in ``cost_price``. The barcode of the item is
- encoded in ``barcode``, while the item supplier is
- identified by ``supplier_ID``. Items may also be
- classified into categories using the ``category`` field.
- Useful categories might include: ``soft drinks``,
- ``alcoholic drinks``, ``cigarettes``, ``knives``,
- ``confectionery``, ``bakery``, ``fruit&vegetables``,
- ``meat``, etc..
-
-Personnel System: Assistants
-############################
-
- .. table:: Table 4. Assistants Database
-
- +----------------------+----------------------+-----------------------+
- | Table | Fields | Description |
- +======================+======================+=======================+
- | ASSISTANTS | assistant_ID, | Database table |
- | | surname, firstname, | describing each |
- | | middlename, age, | *HyperM* sales |
- | | grade, phone_number, | assistant |
- | | …​ | |
- +----------------------+----------------------+-----------------------+
-
- .. container:: paragraph
-
- The database table ``ASSISTANTS`` has a row for each
- sales assistant employed by *HyperM*. Each assistant is
- identified by an ``assistant_ID`` value, with their name
- given in the ``firstname``, ``middlename`` and
- ``surname`` fields. The assistant’s age in years is given
- in ``age``, while their phone number is contained in the
- ``phone_number`` field. The assistant’s grade is encoded
- in ``grade``. Useful values for ``grade`` might include:
- ``trainee``, ``operator``, ``supervisor``, etc..
-
-Locations: Branches
-####################
-
- .. table:: Table 5. Branches Database
-
- +----------------------+----------------------+-----------------------+
- | Table | Fields | Description |
- +======================+======================+=======================+

- | | branch_Name, | describing each |
- | | category, street, | *HyperM* branch |
- | | city, country, | |
- | | postcode, …​ | |
- +----------------------+----------------------+-----------------------+
-
- .. container:: paragraph
-
- *HyperM* operates a number of branches. Each branch is
- described in the ``BRANCHES`` database table. Each branch
- is identified by a ``branch_ID``, with a branch name
- given in ``branch_Name``. The address for the branch is
- encoded in ``street``, ``city``, ``country`` and
- ``postcode``. The branch category is given in the
- ``category`` field. Useful values for ``category`` might
- include: ``Small``, ``Large``, ``Super``, ``Hyper``,
- etc..
-
-Policy Step 1
--------------
-
-Scenario
-#########
- .. container:: paragraph
-
- For the first version of our policy, let’s start with
- something simple. Let us assume that there exists some
- restriction that alcohol products cannot be sold before
- 11:30am. In this section we will go through the necessary
- steps to define a policy that can enforce this for
- *HyperM*.
-
- .. container:: ulist
-
- - Alcohol cannot be sold before 11:30am.
-
-Create the an new empty Policy Model ``MyFirstPolicyModel``
-###########################################################
-
- .. container:: paragraph
-
- Since an organisation like *HyperM* may have many
- policies covering many different domains, policies should
- be grouped into policy sets. In order to edit or deploy a
- policy, or policy set, the definition of the policy(ies)
- and all required events, tasks, states, etc., are grouped
- together into a 'Policy Model'. An organization might
- define many Policy Models, each containing a different
- set of policies.
-
- .. container:: paragraph
-
- So the first step is to create a new empty Policy Model
- called ``MyFirstPolicyModel``. Using the APEX Policy
- Editor, click on the 'File' menus and select 'New'. Then
- define our new policy model called
- ``MyFirstPolicyModel``. Use the 'Generate UUID' button to
- create a new unique ID for the policy model, and fill in
- a description for the policy model. Press the ``Submit``
- button to save your changes.

- 'Generate UUID' button to create a new unique ID for the
- event type, and fill in a description for the event. Add
- a namespace, e.g. ``com.hyperm``. We can add hard-coded
- strings for the ``Source`` and ``Target``, e.g. ``POS``
- and ``APEX``. At this stage we will not add any parameter
- fields, we will leave this until later. Use the

-
- .. container:: title
-
- Field Schema types
-
- .. container:: paragraph
-
- APEX natively supports schema definitions in ``Java`` and ``Avro``.
-
- .. container:: paragraph
-
- ``Java`` schema definitions are simply the name of a Java Class. There are some restrictions:
-
- .. container:: ulist
-
- - the class must be instantiatable, i.e. not an Java interface or abstract class
-
- - primitive types are not supported, i.e. use ``java.lang.Integer`` instead of ``int``, etc.
-
- - it must be possible to find the class, i.e. the class must be contained in the Java classpath.
-
- .. container:: paragraph
-
- ``Avro`` schema definitions can be any valid `Avro <https://avro.apache.org/docs/current/spec.html>`__
- schema. For events using fields defined with ``Avro`` schemas, any incoming event containing that field must
- contain a value that conforms to the Avro schema.
-
- .. container:: paragraph
-
- Click on the 'Events' tab, then right click the
- ``SALE_INPUT`` row and select 'Edit Event
- :literal:`SALE_INPUT’. To add a new event parameter use the 'Add Event Parameter' button at the bottom of the screen. For the `SALE_INPUT`
- event add the following event parameters:
-

- .. tip::
- Optional Fields in APEX Events
- Parameter fields can be *optional* in events. If a parameter is not marked as *optional* then by default it
- is *mandatory*, so it must appear in any input event passed to APEX. If an *optional* field is not set

-###############################################################
-
- .. container:: paragraph
-
- APEX policies are defined using a state-machine model.
- Each policy comprises one or more *states* that can be
- individually executed. Where there is more than one
- *state* the states are chained together to form a
- `Directed Acyclic Graph
- (DAG) <https://en.wikipedia.org/wiki/Directed_acyclic_graph>`__
- of states. A *state* is triggered by passing it a single
- input (or 'trigger') event and once executed each state
- then emits an output event. For each *state* the logic
- for the *state* is embedded in one or more *tasks*. Each
- *task* contains specific *task logic* that is executed by
- the APEX execution environment each time the *task* is
- invoked. Where there is more than one *task* in a *state*
- then the *state* also defines some *task selection logic*
- to select an appropriate task each time the *state* is
- executed.
-
- .. container:: paragraph
-
- Therefore, to create a new policy we must first define
- one or more tasks.
-
- .. container:: paragraph
-
- To create a new Task click on the 'Tasks' tab. In the
- 'Tasks' pane, right click and select 'Create new Task'.
- Create a new Task called ``MorningBoozeCheck``. Use the
- 'Generate UUID' button to create a new unique ID for the
- task, and fill in a description for the task.

- for a task use the 'Add Task Input Field' and 'Add Task
- Output Field' button. The list of input and out fields to
- add for the ``MorningBoozeCheck`` task are given below.
- The input fields are drawn from the parameters in the
- state’s input event, and the task’s output fields are
- used to populate the state’s output event. The task’s
- input and output fields must be a subset of the event
- parameters defined for the input and output events for
- any state that uses that task. (You may have noticed that
- the input and output fields for the ``MorningBoozeCheck``
- task have the exact same names and reuse the item schemas
- that we used for the parameters in the ``SALE_INPUT`` and

- Each task must include some 'Task Logic' that implements
- the behaviour for the task. Task logic can be defined in
- a number of different ways using a choice of languages.
- For this task we will author the logic using the
- Java-like scripting language called
- ```MVEL`` <https://en.wikipedia.org/wiki/MVEL>`__.
-

-
- For simplicity use the following code for the task logic.
- Paste the script text into the 'Task Logic' box, and use

-
- .. container:: paragraph
-
- This logic assumes that all items with ``item_ID``
- between 1000 and 2000 contain alcohol, which is not very
- realistic, but we will see a better approach for this
- later. It also uses the standard ``Java`` time utilities
- to check if the current time is between ``00:00:00 GMT``
- and ``11:30:00 GMT``. For a detailed guide to how to

-
- .. container:: paragraph
-
- Each policy must have at least one state. Since this is
- 'freeform' policy we can add as many states as we wish.
- Let’s start with one state. Add a new state called

- using the 'Add new State' button after filling in the

- Each policy must define a 'First State' and a 'Policy
- Trigger Event'. The 'Policy Trigger Event' is the input
- event for the policy as a whole. This event is then
- passed to the first state in the chain of states in the
- policy, therefore the 'Policy Trigger Event' will be the
- input event for the first state. Each policy can only
- have one 'First State'. For our ``MyFirstPolicy`` policy,
- select ``BoozeAuthDecide`` as the 'First State'. This
- will automatically select ``SALE_INPUT`` as the 'Policy
- Trigger Event' for our policy.

- State Output Mappings
-
- .. container:: paragraph
-
- In a 'Policy' 'State' a 'State Output Mapping' has 3 roles:
- 1) Select which 'State' should be executed next, 2) Select
- the type of the state’s 'Outgoing Event', and 3)
- Populate the state’s 'Outgoing Event'. This is how states are
- chained together to form a (`Directed Acyclic Graph
- (DAG) <https://en.wikipedia.org/wiki/Directed_acyclic_graph>`__ )
- of states. The final state(s) of a policy are those that do
- not select any 'next' state. Since a 'State' can only
- accept a single type of event, the type of the event emitted
- by a previous 'State' must be match the incoming event type
- of the next 'State'. This is also how the last state(s) in
- a policy can emit events of different types. The 'State
- Output Mapping' is also responsible for taking the
- fields that are output by the task executed in the state and
- populating the state’s output event before it is emitted.
-
- .. container:: paragraph
-
- Each 'Task' referenced in 'State' must have a defined
- 'Output Mapping' to take the output of the task, select an
- 'Outgoing Event' type for the state, populate the state’s
- outgoing event, and then select the next state to be
- executed (if any).
-
- .. container:: paragraph
-
- There are 2 basic types of output mappings:
-
- .. container:: olist arabic
-
- #. **Direct Output Mappings** have a single value for
- 'Next State' and a single value for 'State Output
- Event'. The outgoing event for the state is
- automatically created, any outgoing event parameters
- that were present in the incoming event are copied
- into the outgoing event, then any task output fields
- that have the same name and type as parameters in the
- outgoing event are automatically copied into
- the outgoing event.
-
- #. **Logic-based State Output Mappings / Finalizers**
- have some logic defined that dynamically selects
- and creates the 'State Outgoing Event', manages
- the population of the outgoing event parameters
- (perhaps changing or adding to the outputs from the
- task), and then dynamically selects the next state to
- be executed (if any).
-
- .. container:: paragraph
-
- Each task reference must also have an associated 'Output
- State Mapping' so we need an 'Output State Mapping' for
- the ``BoozeAuthDecide`` state to use when the
- ``MorningBoozeCheck`` task is executed. The simplest type
- of output mapping is a 'Direct Output Mapping'.
-
- .. container:: paragraph
-
- Create a new 'Direct Output Mapping' for the state called
- ``MorningBoozeCheck_Output_Direct`` using the 'Add New
- Direct State Output Mapping' button. Select ``SALE_AUTH``
- as the output event and select ``None`` for the next
- state value. We can then select this output mapping for
- use when the the ``MorningBoozeCheck`` task is executed.
- Since there is only state, and only one task for that
- state, this output mapping ensures that the
- ``BoozeAuthDecide`` state is the only state executed and
- the state (and the policy) can only emit events of type
- ``SALE_AUTH``. (You may remember that the output fields
- for the ``MorningBoozeCheck`` task have the exact same
- names and reuse the item schemas that we used for the
- parameters in ``SALE_AUTH`` event. The
- ``MorningBoozeCheck_Output_Direct`` direct output mapping
- can now automatically copy the values from the
- ``MorningBoozeCheck`` task directly into outgoing
- ``SALE_AUTH`` events.)

- this configuration in
- ``$APEX_HOME/examples/config/MyFirstPolicy/1/MyFirstPolicyConfigStdin2StdoutJsonEvent.json``.
- This configuration expects incoming events to be in
- ``JSON`` format and to be passed into the APEX Engine
- from ``stdin``, and result events will be printed in
- ``JSON`` format to ``stdout``. This configuration loads
- the policy model stored in the file
- 'MyFirstPolicyModel_0.0.1.json' as exported from the APEX

-Scenario
-#########
- .. container:: paragraph
-
- *HyperM* have just opened a new branch in a different
- country, but that country has different rules about when
- alcohol can be sold! In this section we will go through
- the necessary steps to extend our policy to enforce this
- for *HyperM*.
-
- .. container:: ulist
-
- - In some branches alcohol cannot be sold before 1pm,
- and not at all on Sundays.
-
- .. container:: paragraph
-
- Although there are a number of ways to accomplish this
- the easiest approach for us is to define another task and
- then select which task is appropriate at runtime
- depending on the branch identifier in the incoming event.

- This task also requires some 'Task Logic' to implement
- the new behaviour for this task.
-
- .. container:: paragraph
-
- For simplicity use the following code for the task logic.
- It again assumes that all items with ``item_ID`` between
- 1000 and 2000 contain alcohol. We again use the standard
- ``Java`` time utilities to check if the current time is
- between ``00:00:00 CET`` and ``13:00:00 CET`` or if it is
- ``Sunday``.
-
- .. container:: paragraph
-
- For this task we will again author the logic using the
- ```MVEL`` <https://en.wikipedia.org/wiki/MVEL>`__
- scripting language. Sample task logic code (specified in
- ```MVEL`` <https://en.wikipedia.org/wiki/MVEL>`__) is
- given below. For a detailed guide to how to write your
- own logic in
- ```JavaScript`` <https://en.wikipedia.org/wiki/JavaScript>`__,

- To add our new task ``MorningBoozeCheckAlt1``, scroll
- down to the ``BoozeAuthDecide`` state in the 'States'
- section. In the 'State Tasks' section for
- ``BoozeAuthDecide`` use the 'Add new task' button. Select
- our new ``MorningBoozeCheckAlt1`` task, and use the name
- of the task as the 'Local Name' for the task. The
- ``MorningBoozeCheckAlt1`` task can reuse the same
- ``MorningBoozeCheck_Output_Direct`` 'Direct State Output
- Mapping' that we used for the ``MorningBoozeCheck`` task.
- (Recall that the role of the 'State Output Mapping' is to
- select the output event for the state, and select the
- next state to be executed. These both remain the same as
- before.)
-
- .. container:: paragraph
-
- Since our state has more than one task we must define
- some logic to determine which task should be used each
- time the state is executed. This *task selection logic*
- is defined in the state definition. For our
- ``BoozeAuthDecide`` state we want the choice of which
- task to use to be based on the ``branch_ID`` from which
- the ``SALE_INPUT`` event originated. For simplicity sake
- let us assume that branches with ``branch_ID`` between
- ``0`` and ``999`` should use the ``MorningBoozeCheck``
- task, and the branches with with ``branch_ID`` between
- ``1000`` and ``1999`` should use the
- ``MorningBoozeCheckAlt1`` task.
-
- .. container:: paragraph
-
- This time, for variety, we will author the task selection
- logic using the
- ```JavaScript`` <https://en.wikipedia.org/wiki/JavaScript>`__
- scripting language. Sample task selection logic code
- (specified in
- ```JavaScript`` <https://en.wikipedia.org/wiki/JavaScript>`__)
- is given below. Paste the script text into the 'Task
- Selection Logic' box, and use "JAVASCRIPT" as the 'Task
- Selection Logic Type / Flavour'. It is necessary to mark
- one of the tasks as the 'Default Task' so that the task
- selection logic always has a fallback default option in
- cases where a particular task cannot be selected. In this
- case the ``MorningBoozeCheck`` task can be the default
- task.

- To test the policy try paste the following events into
- the console as the APEX engine executes. Note, all tests
- from Step 1 will still work perfectly since none of those
- events originate from a branch with ``branch_ID`` between
- ``1000`` and ``2000``. The 'Task Selection Logic' will
- therefore pick the ``MorningBoozeCheck`` task as
- expected, and will therefore give the same results.

- If the local time is between 00:00:00 CET and 13:00:00 CET then the sale is not authorised.
- Also alcohol sales are not allowed on Sundays. Otherwise the sale is authorised.
- In this implementation we assume that items with item_ID between 1000 and 2000 are all alcoholic drinks :-)
