Web services having live data updates

Abstract

A method, apparatus, and computer program product for communicating real-time updates among web clients. A structured data object is composed from a set of data nodes according to a domain specific language in response to requesting access to a data within a human resources database. The structured data object is interpreted within a context of a record ID/form to identify content for the web page and to determine whether real-time updates are enabled for the web page. Interpreting the structured data object, displays the form with the content. An event queue is created and a connection to the server hub is established when real-time updates are enabled. In response to receiving an update event in the event queue, a notification of the update event is displayed when the update event matches the record ID/form that a first user has opened.

         22 . A method for communicating real-time updates among web clients, the method comprising:
 receiving, by a computer system responsive to requesting access to a data record stored in a database, a data object comprising a set of data nodes according to a domain specific language, the data object defining a layout for a webpage form;   interpreting, by the computer system, the data object within a context of the data record to identify content for the webpage form;   creating, by the computer system responsive to determining that the data object enables real-time updates for the webpage form, an event queue;   displaying, by the computer system, the webpage form with the identified content; and   displaying, by the computer system responsive to determining that an update event in the event queue matches a record identifier for the data record, a notification and content of the update event.   
     
     
         23 . The method of  claim 22 , wherein the update event is a notification of changes to the content for the webpage form, the changes to the content for the webpage form including at least one of:
 an addition of a second data record;   opening of a second webpage form by a user for editing the data record; or   updating of the data record by user.   
     
     
         24 . The method of  claim 22 , further comprising:
 providing, by the computer system, a prompt to a user for a response to the update event, the prompt including at least one of:
 a message to update the content displayed; 
 a message to discard changes made by a second user; or 
 a message to merge the content with the changes made by the second user. 
   
     
     
         25 . The method of  claim 22 , further comprising:
 updating, by the computer system, the content displayed in the webpage form based on information in the update event without refreshing, reloading, or otherwise re-retrieving relevant content for the webpage form.   
     
     
         26 . The method of  claim 22 , further comprising:
 establishing, by the computer system, a connection to a server, the connection providing asynchronous bi-directional communication between a client browser and the server using an Application Program Interface.   
     
     
         27 . The method of  claim 26 , wherein the connection is a web socket connection. 
     
     
         28 . The method of  claim 22 , wherein the update event is a compressed JSON syntax of the data record including the record identifier, a data source, and changed values of the data record. 
     
     
         29 . A computer system, comprising:
 a hardware processor; and   a web browser, in communication with the hardware processor, the web browser configured to:
 receive, in response to a request for access to a data record stored in a database, a data object comprising a set of data nodes according to a domain specific language, the data object defining a layout for a webpage form; 
 interpret the data object within a context of the data record to identify content for the webpage form; 
 create, responsive to determining that the data object enables real-time updates for the webpage form, an event queue; 
 display the webpage form with the identified content; and 
 display, responsive to determining that an update event in the event queue matches a record identifier for the data record, a notification and content of the update event. 
   
     
     
         30 . The computer system of  claim 29 , wherein the update event is a notification of changes to the content for the webpage form, the changes to the content for the webpage form including at least one of:
 an addition of a second data record;   opening of a second webpage form by a user for editing the data record; or   updating of the data record by user.   
     
     
         31 . The computer system of  claim 29 , the web browser is further configured to:
 provide a prompt to a user for a response to the update event, the prompt including at least one of:
 a message to update the content displayed; 
 a message to discard changes made by a second user; or 
 a message to merge the content with the changes made by the second user. 
   
     
     
         32 . The computer system of  claim 29 , the web browser is further configured to:
 update the content displayed in the webpage form based on information in the update event without refreshing, reloading, or otherwise re-retrieving relevant content for the webpage form.   
     
     
         33 . The computer system of  claim 29 , the web browser is further configured to:
 establish a connection to a server, the connection providing asynchronous bi-directional communication between a client browser and the server using an Application Program Interface.   
     
     
         34 . The computer system of  claim 33 , wherein the connection is a web socket connection. 
     
     
         35 . The computer system of  claim 29 , wherein the update event is a compressed JSON syntax of the data record including the record identifier, a data source, and changed values of the data record. 
     
     
         36 . One or more non-transitory computer readable storage media having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to implement operations comprising:
 receiving a data object composed from a set of data nodes according to a domain specific language, the data object defining a layout for a webpage form;   interpreting, using a data record, the data object to identify content for the webpage form;   creating, responsive to determining that the data object enables real-time updates for the webpage form, an event queue;   displaying the webpage form with the content; and   displaying, responsive to determining that an update event in the event queue matches a record identifier for the data record, a notification and content of the update event.   
     
     
         37 . The one or more non-transitory computer readable storage media of  claim 36 , wherein the update event is a notification of changes to the content for the webpage form, the changes to the content for the webpage form including at least one of:
