Creating a Model
```sql USE MDS GO CREATE MODEL CustomerModel GO ```Adding Entities to the Model
```sql USE MDS GO INSERT INTO CustomerModel (EntityID, EntityName) VALUES (1, 'Customer') GO ```Defining Attributes
```sql USE MDS GO ALTER MODEL CustomerModel ADD ATTRIBUTE CustomerName NVARCHAR(50) GO ```These code snippets demonstrate the basic steps involved in setting up a model, adding entities, and defining attributes in Master Data Services.
