MATRIXX Subscriber Management API
Subscriber Management
The following information is an overview of the SubMan APIs and architecture.
Subscriber Data
MATRIXX Engine maintains transactional subscriber data that enables you to address in real time subscriber needs and service usage. The MATRIXX subscriber model is flexible and supports any type of subscriber base, such as retail, wholesale, and Mobile Virtual Network Operator (MVNO).
MATRIXX Data Containers
MATRIXX Data Containers (MDCs) are the fundamental data structures used by MATRIXX. They hold objects in the in-memory databases and carry messages through the system. The messages are for incoming network events, subscriber care activities, pricing updates, and any activity that must be handled transactionally.
Subscriber In-Memory Data Relationships
The subscriber data objects are held in the databases in MDCs. Each one inherits information from its parent MDC and can be related to other MDCs based on their contained fields.

MATRIXX Subscriber Management API
- About Subscriber Management API
  MATRIXX Subscriber Management API provides information about the MATRIXX Engine APIs, including functions, syntax, and result codes, and the MATRIXX Engine REST and Java API implementations.
- Subscriber Management
  The following information is an overview of the SubMan APIs and architecture.
  - SubMan Overview
    The Subscriber Management (SubMan) API defines a set of programming interfaces to the MATRIXX in-memory databases.
  - Architecture and Deployment
    The SubMan API is the externally visible element of the Subscriber Management interface. The interface uses a standard client-server model, where a MATRIXX gateway is the server and any external application that needs to access and manipulate data related to subscribers and groups is the client. The SubMan AP has two language bindings: Java and REST.
  - Message Workflow
    The diagrams in this section show the API message workflow for primary and secondary resources.
  - Data Objects
    An external application or system can use the SubMan APIs to perform operations on primary, secondary, and embedded objects. Primary objects can be called directly by the API and include subscribers, groups, devices, and users. Wallets are secondary objects because they belong to a primary object. Operations on wallets must reference a primary object. Embedded objects include product offers, balances, thresholds, and billing cycles.
  - Subscriber Data
    MATRIXX Engine maintains transactional subscriber data that enables you to address in real time subscriber needs and service usage. The MATRIXX subscriber model is flexible and supports any type of subscriber base, such as retail, wholesale, and Mobile Virtual Network Operator (MVNO).
    - Subscription-Related Database Objects
      Database objects related to subscriptions include: subscriber, device, group, user, wallet, balance, balanceSet, product offer, bundle, session, activity, and event.
    - Subscriber Data Model
      MATRIXX Engine maintains transactional subscriber data that enables you to act in real-time to subscriber needs and service usage. The subscriber management data model is exposed through MATRIXX Data Container (MDC) definitions.
    - MATRIXX Data Containers
      MATRIXX Data Containers (MDCs) are the fundamental data structures used by MATRIXX. They hold objects in the in-memory databases and carry messages through the system. The messages are for incoming network events, subscriber care activities, pricing updates, and any activity that must be handled transactionally.
      - Subscriber In-Memory Data Relationships
        The subscriber data objects are held in the databases in MDCs. Each one inherits information from its parent MDC and can be related to other MDCs based on their contained fields.
      - MATRIXX Data Container Field Data Types
        MATRIXX Engine supports several data types for its network message MATRIXX Data Containers (MDCs) and database object MDCs. When you define custom MDCs and MDC fields, you must specify one of these data types for the fields.
      - REST and Java Data Type Mapping
        REST and Java data types must map to their corresponding MATRIXX data types.
  - Functions
    The SubMan API functions provide a standardized way to define, send, and receive MATRIXX data. They support generic arguments so applications can use the same programming primitives to communicate with MATRIXX Engine.
  - Syntax
    The generic syntax of each API request and response operation includes a description, the base MDC container used by the operation, and the data elements used by the operation.
  - SubMan API Result Codes
    Each response includes a basic result code indicating success or failure and textual information about any failure. A result code of 0 (zero) is a success and a result code of nonzero is a failure.
  - Domain Routing
    The SubMan API calls include domain routing information.
  - Execute Mode
    The SubMan API execute mode determines if data changes are saved to the internal database when a SubMan API call is made and if credit limits are ignored.
  - MDC Serialization
    The data container package for MATRIXX Java components provides three different formats for serialization: XML, JSON, and OpenAPI JSON. These serialization formats depend on MATRIXX MDC definition files. MDC serialization describes data containers, structs, simple types, arrays and lists, and special fields.
- Object Management
  The following sections introduce how the various in-memory objects are managed.
- SubMan API Reference
  The SubMan API reference includes SubMan API and MDC descriptions.
- REST API Management
  RS Gateway supports the REST API bindings for accessing subscriber data in MATRIXX Engine. RS Gateway consists of an rsgateway application and a set of REST APIs.
- REST API Reference
  This part describes how to use the REST API bindings to interface with MATRIXX Engine.
- Java API
  This part provides an overview of how to use the Java™ API binding for the SubMan v3 API as an interface to the MATRIXX Engine.

Subscriber In-Memory Data Relationships

The subscriber data objects are held in the databases in MDCs. Each one inherits information from its parent MDC and can be related to other MDCs based on their contained fields.

For example, all MDCs have the same top-level MDC, MtxObject, that holds Object ID and External ID values for each MDC instance in the database. As another example, the MtxLoginDeviceObject and MtxMobileDevice objects both point to the MtxDeviceObject for information.

MDCs can be related to one another by containing fields that reference the other MDC. For example, the MtxSubscriberObject contains an AdminGroupArray field with a certain value for a subscription. That value is located in the AdminIdArray field in the MtxGroupObject to which it belongs.
