The invention discloses an incremental change method and system based on a version number, and the method comprises the steps: configuring three types of identification fields of version, state and deletion for business data, defining the value rule and business mapping relation of each field, and achieving the unified identification of the attribute, effective state and deletion state of the data version. And receiving a data change request, identifying a change type and the target data, only executing an operation on the changed data, and keeping the original information of the unchanged data. And synchronously updating the three types of fields during change, copying the target data to generate new data, keeping a historical state, and not modifying the core content of the original version. A traceable storage mode is adopted, data and field information of all iteration versions are stored, key operation information is recorded, unchanged data are not stored repeatedly, and data full-life-cycle tracing is achieved. And receiving a version query request, screening according to a screening rule, and returning a complete and effective data set of a target version. And the requirement of service iteration on the accuracy of data management is met.

The embodiment of the application provides a commissioning and rollback method and system for a communication system configuration, comprising: loading a current effective configuration in a front-end workstation, generating an incremental snapshot in response to an input incremental change instruction; generating a virtual production configuration based on the incremental snapshot and the current effective configuration; generating and outputting a trajectory log based on the virtual production configuration and simulation input parameters; performing configuration mapping on the trajectory log to obtain configuration rule hit information; performing commissioning and pre-checking based on the configuration rule hit information, generating and outputting risk information; generating a commissioning passing instruction through the risk information, and submitting the incremental snapshot to a back-end; when detecting that abnormal information appears in a database transaction, performing a reverse patch to realize atomic rollback; and connecting each incremental change instruction and the reverse patch to a configuration version tree to preview the configuration of any historical node. The method realizes atomic submission and accurate rollback, and can quickly restore the system to an accurate state before the change.

A system performs a distributed version control on a data lake. A change to the data lake can be performed within a single atomic commit that defines a set of changes. Commits are built on top of each other and describe incremental changes, which creates a sequence of atomic commits that defines a history of changes. The commits can be identified by hash values, and branches can be defined to refer to commits. A new commit updates a branch head reference to the new commit so that the branch head always refers to the latest version of a chain of commits in the branch. The system can create tags that define, for example, a release version and can merge source commits onto target commits including merging the head of one branch onto the head of another branch.

The application discloses a kind of physical view incremental refreshing method, device, equipment, medium and product, it is related to database technical field.The method comprises: dividing base table, obtains at least two sub-tables of shard;Log temporary table and log main table of physical view are created for the sub-table of shard;In data shard, shard local physical view is created, and incremental refreshing control information is registered;According to incremental refreshing point, the log temporary table and the log main table determine incremental change set;According to the base table involved in the shard local physical view and the incremental change set, the shard local physical view is refreshed, obtains the new shard local physical view or intermediate result set of the sub-table of shard;At least two new shard local physical views or intermediate result sets of sub-table of shard are merged, and the target physical view of the base table is obtained.
