(Optionally) Including the implementation of service contracts, although not their definition.

Service Layer

Resides below the presentation layer & above the domain layer. Contains service contracts, which define how the implementation will behave. Provides an easy way to access the REST/SOAP API framework code (which also resides above the service contracts). You can bind service contracts to web service APIs in configuration files — no coding required. Provides a stable API for other modules to call into.

the following, as detailed in the description of the applicable Base Package: Advanced Reporting

Declarative XML Schemas are what?

XML files that are used to specify the final state of the database. These files replace PHP update scripts that were required when upgrading a module. These files allow you to skip the progressive upgrade scripts and jump right to the final state of the database.

What are some of the standard features of Magento's Business Intelligence Pro?

1. Technical Support 2. Implementation 3. Service Configuration items (allotments identified in the Sales Order): Business Intelligence integrations

Advantages of service contracts

1. allow you to add a new customer extension that adds or changes business logic-level resource models without breaking the system. 2.This is done using the <preference> element in a custom module's dependency injection configuration file (di.xml) file.( specifies the class to use for the interface Magento\Customer\Api\CustomerRepositoryInterface.) 3. Another module can change this interface file by specifying a different class name. However, if the client code uses the interface definition only, no class change is necessary.

Some objects have a vast number of attributes, or they could have a set related objects that have varying numbers of attributes, theses objects are constructed using what?

Entity-Attribute-Value (EAV) models.

The Persistence layer resource model is responsible for....

Executing all CRUD (create, read, update, delete) requests. The resource model contains the SQL code for completing these requests. Performing additional business logic. Like a resource model could perform data validation, start processes before/after data is saved, or perform other db operations.

Persistence layer

M uses an active record pattern strategy for this layer. In this system, the model object contains a resource model that maps an object to one or more db rows

The 3 main ways of accessing the domain layer is by?

Service contracts A module can directly call into another module. Domain code in one module can also plug itself into another module using, event hooks, plugins, di.xml files (with an SPI contract)

Service contracts Api Directory contains what?

Service interfaces in the /Api namespace of the module (Catalog API). Data (or entity) interfaces in the Api/Data directory (Catalog API/Data[]). Data entities* are data structures passed to and returned from service interfaces . Files in the data directory contain get() and set() methods for entries in the entity table and extension attributes.

The best practice regarding the Domain layer is?

Use service contracts to communicate with the domain layer by passing data types through strongly typed objects. This helps you avoid the need to replace presentation layer code when replacing business layer logic.
