Database upgrade management

摘要

A system can include an upgrade system manager. The upgrade system manager can be configured to communicate with an upgrade database that employs a given schema. The system can also include a legacy system manager configured to communicate with a legacy database that employs a different schema, wherein the legacy database contains a subset of the data stored at the upgrade database. The legacy database can be configured to provide a forward migration trigger to the upgrade system manager in response to detecting an update to the legacy database. The upgrade system manager can further be configured to determine whether data received from an application configured to produce data for the upgrade database is to be provided to the legacy database.

one or more non-transitory memory to store machine-readable instructions; andone or more processors to access the memory and execute the machine-readable instructions;wherein the machine-readable instructions comprise:
an upgrade system manager, configured to communicate with an upgrade database that employs a given schema; anda legacy system manager configured to communicate with a legacy database that employs another schema, wherein the legacy database contains a subset of the data stored at the upgrade database;wherein the legacy database is configured to provide a forward migration trigger to the upgrade system manager in response to detecting an update to the legacy database;wherein the upgrade system manager is further configured to determine whether data, received from an application configured to produce data for the upgrade database, is to be provided to the legacy database based on a type of data received from the application, wherein the upgrade system manager is configured not to provide the data received from the application to the legacy system manager if the data is a given type of data and to provide the data received from the application to the legacy system manager if the data is another type of data; andwherein the data received from the application is written to the upgrade database and to the legacy database in response to the providing of the data received from the database to the legacy database.
