1. A system comprising:
- one or more hardware processors;
a computer readable data storage device coupled to the one or more hardware processors, the computer readable data storage device having stored thereon software instructions that, when executed by the one or more hardware processors, cause the one or more hardware processors to perform operations including;
receiving an electronic message associated with a child table, the electronic message including one or more received change notifications and including at least one or more data values from a previous clock cycle;
updating an index of the child table based on the one or more received change notifications, where the index of the child table includes a mapping between one or more index values in the child table and corresponding positions in one or more data columns mapped by a columns source map of the child table, where the corresponding positions include positions for which data in the one or more data columns is valid for the child table;
when the child table has one or more dependent tables that depend on data of the child table, generating one or more other electronic messages associated with the one or more dependent tables, the one or more other electronic messages containing a child table change notification indicating an update made to the child table; and
when one or more other electronic messages are generated, providing the one or more other electronic messages to the one or more dependent tables.

1. A system comprising:
-
one or more hardware processors; a computer readable data storage device coupled to the one or more hardware processors, the computer readable data storage device having stored thereon software instructions that, when executed by the one or more hardware processors, cause the one or more hardware processors to perform operations including; receiving an electronic message associated with a child table, the electronic message including one or more received change notifications and including at least one or more data values from a previous clock cycle; updating an index of the child table based on the one or more received change notifications, where the index of the child table includes a mapping between one or more index values in the child table and corresponding positions in one or more data columns mapped by a columns source map of the child table, where the corresponding positions include positions for which data in the one or more data columns is valid for the child table; when the child table has one or more dependent tables that depend on data of the child table, generating one or more other electronic messages associated with the one or more dependent tables, the one or more other electronic messages containing a child table change notification indicating an update made to the child table; and when one or more other electronic messages are generated, providing the one or more other electronic messages to the one or more dependent tables. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A method comprising:
-
receiving an electronic message associated with a child table, the electronic message including one or more change notifications indicating a change in one or more parent tables of the child table; updating an index of the child table based on the one or more change notifications, where the index of the child table includes a mapping between one or more index values in the child table and corresponding positions in one or more data columns mapped by a columns source map of the child table, where the corresponding positions include positions for which data in the one or more data columns is valid for the child table, and where the index of the child table is serialized; determining that the child table has one or more dependent tables that depend on data of the child table; after performing the updating, generating one or more other electronic messages associated with the one or more dependent tables, the one or more other electronic messages containing a child table change notification indicating an update made to the child table; and providing the one or more other electronic messages to the one or more dependent tables. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method comprising:
-
receiving an electronic message associated with a child table, the electronic message including one or more change notifications including at least one or more data values from a previous clock cycle; updating an index of the child table based on the one or more change notifications, where the index of the child table includes a mapping between one or more index values in the child table and corresponding positions in one or more data columns mapped by a columns source map of the child table, where the corresponding positions include positions for which data in the one or more data columns is valid for the child tablet; when the child table has one or more dependent tables that depend on data of the child table, generating one or more other electronic messages associated with the one or more dependent tables, the one or more other electronic messages containing a child table change notification indicating an update made to the child table; and when one or more other electronic messages are generated, providing the one or more other electronic messages to the one or more dependent tables. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. A nontransitory computer readable medium having stored thereon software instructions that, when executed by one or more processors, cause the one or more processors to perform operations including:
-
receiving an electronic message associated with a child table, the electronic message including one or more change notifications indicating a change in one or more parent tables of the child table; updating an index of the child table based on the one or more change notifications, where the index of the child table includes a mapping between one or more index values in the child table and corresponding positions in one or more data columns mapped by a columns source map of the child table, where the corresponding positions include positions for which data in the one or more data columns is valid for the child table, and where the columns source map of the child table corresponds to a column source assembled from column data in multiple physical locations; when the child table has one or more dependent tables that depend on data of the child table, generating one or more other electronic messages associated with the one or more dependent tables, the one or more other electronic messages containing a child table change notification indicating an update made to the child table; and when one or more other electronic messages are generated, providing the one or more other electronic messages to the one or more dependent tables. - View Dependent Claims (24, 25, 26, 27, 28, 29)

30. A system comprising:
-
one or more hardware processors; a computer readable data storage device coupled to the one or more hardware processors, the computer readable data storage device having stored thereon software instructions that, when executed by the one or more hardware processors, cause the one or more hardware processors to perform operations including; receiving an electronic message associated with a child table, the electronic message including one or more change notifications indicating a change in one or more parent tables of the child table; updating an index of the child table based on the one or more change notifications, where the index of the child table includes a mapping between one or more index values in the child table and corresponding positions in one or more data columns mapped by a columns source map of the child table, where the corresponding positions include positions for which data in the one or more data columns is valid for the child table, and where the index of the child table is serialized; determining that the child table has one or more dependent tables that depend on data of the child table; and after performing the updating, generating one or more other electronic messages associated with the one or more dependent tables, the one or more other electronic messages containing a child table change notification indicating an update made to the child table. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37)
