Create an entity store with a computed property "p3" and entity and property classes:

Obtain the computed value:

Look up the members of "ec2":

Get an Association of the value of all properties in "pc1" for one entity:

Access the entity store directly:

Values are not computed:

Access properties of an entity class:

Retrieve the raw data stored for "Entities":

Create an entity store of all integers:

Get the numerical value of an entity:

Compute the factorial of the entity "4":

Invalid entities are rejected:

Change the value of the "Factorial" of the entity "7":

This introduces an entity together with the new value into the registered entity store for "integer":

Other entities do not have an explicit value:

Define an EntityStore containing labeled entities and entity classes:

Normally an EntityClass behaves like the list of entities it represents. Get the "Label" for each entity in the class:

To get the "Label" of the class, access the EntityStore directly:

Put an entity store into the cloud:

Share the cloud object with someone who can then use the entities contained in it:

Construct an EntityStore renaming the tables:

Construct an EntityStore with a subset of the columns:

Construct an EntityStore renaming the columns:

Construct an EntityStore with computed types:

Construct an EntityStore with computed properties:

Specify "beehive" entities with a "Date"-qualified "Population" property:

Get the latest population for Lisa's beehive:

Get the population for mid-2014:

Use Dated:

This is equivalent:

Get the time series:

The population of all beehives in 2013:

Create an entity store with people, some of whom are musicians or scientists:

Register the store:

List properties applicable to all people:

Concrete entities can have additional properties:

Get all data for an entity, including data from child types:

When there is no ambiguity, the property of a child type can be specified as a string:

The following uses a complete specification of a child type's property:

List all people working in the field of physics:

List all musicians:

List musicians working in the field of physics:

The result is the intersection of the two previous results:

Create an entity store that contains an initialization expression:

The initialization expression is evaluated upon registration:

Unregister the store:

Create an entity store including metainformation:

Look up the metainformation:
