Abstract: A branch of a main database is created, comprising a copy of the main database schema. A user edits the branch and requests that it be merged back into the main database. A schema diff is generated and used to determine differences between the main database and the edited branch. The merge is performed if it does not create a conflict. A second branch is created and edited by a second user. When the second user indicates to merge the second branch back into the main database, differences between the two branches are determined, relative to the main database. If merging the second branch back into the main database on top of the first branch does not create a conflict, a three-way merge is performed of the first branch, the second branch, and the version of the main database from which the first and second branches were generated.

Abstract: A database system generates an execution plan including multiple operators for processing a database query, for example, a join query or a group by query. The database system allocates a set of threads. Threads communicate with other threads via blocking channels. A blocking channel includes a buffer of a fixed capacity. The database system processes the database query by streaming data through operators of the execution plan. A thread sends data generated by an operator to another thread via the blocking channel if the buffer of the blocking channel has available capacity to store the data, or else the thread blocks until the buffer has capacity to store the data. Similarly, a thread receives data generated by an operator of another thread via the blocking channel if the buffer of the blocking channel has available data, or else the thread blocks until the buffer has data.

Abstract: To determine whether an incorrect category has been associated with an item, the characteristics of the items that are associated with that category are used to determine a representative set of characteristics. If the characteristics of the item differ from the representative set, the item may be associated with a different category by determining a category of items having characteristics similar to those of the item. For an item with associated parent and child categories, the parent categories of other items having the same child category may be compared to the parent category of the item. If the parent categories differ, the item may be associated with a different category by determining a category of items having characteristics similar to those of the item.

Abstract: An entity-centric approach has been proposed to provide a consistent user experience in accessing a unified software applications suite effortlessly. Entities are connected with one another. The entities and the connectivity between them are reflected in all three functional layers of 3-tier client-server architecture. Every entity has a set of attributes and each attribute represents a data item or record of a particular type. The data items or records are represented in the form of card(s) as determined by contextualization and access control engines. Interactions capture entity communications across the unified software suite. The entities can communicate or interact across various channels like mail, call, messages, webinar, etc. Interaction across each channel is possible by one or more software applications. The interactions trends can be represented by channel and by entity. When interactions are filtered by channel, a channel-wise list for each type of interaction, e.g., mail, chat, call, etc.

Abstract: A data query and retrieval system receives a query request and identifies a plurality of data warehouses, or stores, where data needed to satisfy the query is stored. Data items, or fields, called for by the query request are grouped into sets based on fields stored at the same data warehouse. Individual data connections are generated for each data warehouse accessed, and a database view defined for the fields available at each respective data warehouse. The individual views are invoked in a single query statement by a query processor for accessing the respective data warehouses via the corresponding database view. In this manner, a query operator or user need not define multiple query expressions or perform separate queries for accessing data fields or dimensions residing at different data warehouses.

Abstract: Techniques for join elimination are described herein. Join elimination can identify and eliminate unnecessary joins in a query plan node. For example, join elimination can involve a semantic query optimization technique, which removes reference to a table whose columns are only referenced in join predicates if the joins do not filter/expand rows in the result. Such joins can cause significant performance issues on larger datasets if not optimized.

Specifically, the proposed systems enable the intelligent generation of reports from multiple datasets by automatically determining a proposed set of join configurations for combination of the multiple datasets. The proposed set of join configurations can be executed as proposed and/or can be edited or customized by the user to generate reports from the multiple datasets. Thus, the proposed systems and methods can provide intuitive and user-friendly tools for generating data reports that accurately synthesize and summarize data contained in multiple different datasets.
