CRM Form

Dynamics CRM Form  - 2 types  -> Main Form  & Mobile Form

Main Form
CRM will allow to create multiple form for same entity. Each form  - body, header, footer, and navigation pane.

CRM Metadata

Metadata is defined as data about data. MS Dynamics CRM uses a metadata driven architecture to provide the flexibility to create custom entities and additional system entity attributes.
MS Dynamics CRM retrieves the record data from the metadata (entities, attributes, relationships, and option sets.), which in turn retrieves information from the underlying system data. MS Dynamics CRM stores its underlying system data in a relational database using Microsoft SQL Server.

MS Dynamics User Interface  ->  Metadata ->  Underlying System Data (SQL Server)

The entity metadata controls the grid and form layout, and how navigation options are presented. The metadata makes heavy use of MS Dynamics CRM Web services and XML data formats.

Make changes directly to CRM database in Microsoft SQL Server, risk of damaging the metadata and creating errors in your system.

MS Dynamics Entity Relationship

An entity relationship in Microsoft Dynamics CRM defines how two entities interact with each other.
Microsoft Dynamics CRM uses three types of data relationships, which we review in more detail in the following sections:
Hierarchical Relationships - 1:N and N:1

One-to-many (1:N) - relationship between two entities in which a single entity can possess multiple (many) related entities. For Example, Each Account can have many Contacts, but you can assign only one Account to each Contact.

Many-to-one (N:1)
