Light data integration

A non-transitory computer storage medium encoded with computer program instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:

• receiving, by a user interface, a plurality of objects from a functional logic tier of an application, each object representative of data stored in a data tier of the application, a first portion of the stored data being stored in a first persistent data store and a second portion of the stored data being stored in a second persistent data store different from the first persistent data store;
• receiving an indication of an object being selected through the user interface from the plurality of objects;
• in response to receiving the indication causing the functional logic tier to:
• configure a first query for the first portion of the data represented by the selected object, the first query having a first configuration that is based on a first requirement of querying the first persistent data store;
• configure a second query for the second portion of the data represented by the selected object, the second query having a second configuration that is based on a second requirement of querying the second persistent data store, the second requirement being different than the first requirement of querying the first persistent data store, and
• obtain, by executing the first query and the second query, the first portion of data from the first persistent data store and the second portion of data from the second persistent data store;
• and
• presenting, in an area of the user interface, information representing the first portion of data and the second portion of data corresponding to the selected object and retrieved from the functional logic tier;
• wherein the functional logic tier is configured to map a first data type to a neutral data type based on the first requirement for querying the first persistent data store, and wherein the functional logic tier is configured to map a second data type to the neutral data type based on the second requirement for querying the second persistent data store.

A system comprising:

• one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
• receiving, by a user interface, a plurality of objects from a functional logic tier of an application, each object representative of data stored in a data tier of the application, a first portion of the stored data being stored in a first persistent data store and a second portion of the stored data being stored in a second persistent data store different from the first persistent data store;
• receiving an indication of an object being selected through the user interface from the plurality of objects;
• in response to receiving the indication, causing the functional logic tier to:
• configure a first query for the first portion of the data represented by the selected object, the first query having a first configuration that is based on a first requirement of querying the first persistent data store;
• configure a second query for the second portion of the data represented by the selected object, the second query having a second configuration that is based on a second requirement of querying the second persistent data store, the second requirement being different than the first requirement of querying the first persistent data store, and
• obtain, by executing the first query and the second query, the first portion of data from the first persistent data store and the second portion of data from the second persistent data store;
• and
• presenting, in an area of the user interface information representing the first portion of data and the second portion of data corresponding to the selected object and retrieved from the functional logic tier
• wherein the functional logic tier is configured to map a first data type to a neutral data type based on the first requirement for querying the first persistent data store, and
• wherein the functional logic tier is configured to map a second data type to the neutral data type based on the second requirement for querying the second persistent data store.
