Methods, electronic devices and computer program product for replicating metadata
Metadata is replicated. For instance, in response to receiving a request for replicating metadata to a target node, information of an index structure associated with the metadata is obtained. The index structure may include terminal nodes for storing the metadata and index nodes for storing index information of the terminal nodes. Next, the metadata from the terminal nodes is extracted based on the information of the index structure. Further, a sequence is generated to be replicated of the metadata. The sequence to be replicated includes items of the metadata, and locations of the items in the sequence to be replicated are determined based on key information corresponding to the items. In addition, the items of the metadata, in the sequence to be replicated, are replicated to the target node. In this way, only the metadata in the index structure is replicated, thereby reducing the data amount of replication. |

Systems and methods for access to multi-tenant heterogeneous databases
Systems and methods described herein provide heterogeneous access to tenant databases. A delegator intermediary to clients and tenant database receives a request from a client to perform a database related action. The request identifies a query type and tenant identifier. The tenant databases include a first tenant database of a first database type and a second tenant database of a second type. The delegator identifies a tenant database using the tenant identifier from the request. The delegator determines a database type corresponding to the identified tenant database. The delegator selects, from a plurality of drivers corresponding to respective database types, a driver based on a database type for the identified tenant database. The delegator establishes a database connection using the selected driver between the delegator and identified tenant database. The delegator uses the database connection for performing the database related action from the request. |

Statistical processing of natural language queries of data sets
Techniques for processing a natural language query are provided. The techniques include obtaining a set of statistics representing a contextual significance of a set of words in a data model for a data set. Next, the set of statistics is used to match a set of semantic intents for a natural language query of the data set to one or more data elements in the data model. The data element(s) and the data set are then to generate a result of the natural language query, and the result is provided in a response to the natural language query. |

Techniques for searching using target applications
A user device includes a processing unit that executes a search application. Executing the search application causes the processing unit to receive a user search query, send the user search query to a plurality of target applications, and receive a set of search results from each of the target applications. Each search result includes application state access data configured to access an application state of the target application associated with the search result. Executing the search application causes the processing unit to rank the search results, display the ranked search results, and detect user selection of one of the displayed search results. Additionally, executing the search application causes the processing unit to send the application state access data associated with the selected search result to the target application associated with the selected search result and display the application state accessed using the application state access data. |

Transient materialized view rewrite
Queries executed against a materialized view can execute up to orders of magnitude faster than equivalent queries on a source (or base) table. However, although a query can reference a materialized view directly, a user (e.g., query author) may not know about a relevant materialized view. Moreover, if a source table has multiple materialized views generated, the user may not know which materialized view to reference in the query. Thus, embodiments of the present disclosure provide techniques for automatically rewriting queries directed to a source table to utilize existing materialized views. |
