Abstract: A database management system (DBMS) performs, in response to a conversion request to convert a store format of a table in a database, a process (base type change process) for changing a store format indicated by information (base type) indicating the store format of the table to a store format according to the conversion request, and performs a data conversion process asynchronously with the aforementioned process. In an import process after the base type change process, the DBMS imports, into the table, a chunk in the store format indicated by the base type after change. In the data conversion process, the DBMS converts a chunk in a store format different from the store format indicated by the base type into a chunk in the store format indicated by the base type.

Abstract: A method and an inclusion dependency determination system (IDDS) for determining inclusion dependency between columns of tables in a target database to establish primary key (PK)-foreign key (FK) relationships among data in the columns with minimized disk input and output operations are provided. The IDDS determines dependency characteristic data (DCD) of each column and arranges the columns by applying one or more predefined rules to the columns based on a minimum value of the data of each column. The IDDS determines pairs of arranged columns that demonstrate a possibility of inclusion dependency based on the DCD and identifies a first column and a second column of each determined pair as a candidate PK and a candidate FK respectively. The IDDS determines inclusion dependency between the candidate PK and the candidate FK on comparing data of the candidate PK with the data of the candidate FK using dynamically determined search techniques.

Abstract: A method, apparatus, and computer program product for validating a structured data object. A computer system identifies rules for validating interrelationships among data nodes. The data nodes are composable into structured data objects according to a domain specific language. The validation rules are topologically sorted according to dependency relationships declared therein. The computer system receives the structured data object, which consists of interrelated data nodes. The structured data object is traversed according to a traversal algorithm that tracks dependency relationships. Each data node is inserted into a queue according to the traversal algorithm. For each data node in the queue, a subset of the validation rules is identified. The subset is run within a context of the structured data object. Rule failure for the data node are recorded, and a failure report is generated that indicates failure results for each data node.

Abstract: Introduced here are various embodiments for selectively assigning a query to an expert. A network-accessible server system may receive a query from a client device indicating a question or project proposal. The query text may be parsed and attributes of the query may be determined by inspecting the parsed query text. The query attributes may be compared with attributes associated with a pool of experts with various specialties and expertise in various fields. The network-accessible server system may match the query attributes with attributes associated with a first expert with a similarity that exceeds a threshold similarity level to identify that an expertise of the first expert matches the requested expertise in the query. The first expert may be assigned to the query and prompted to provide a response to the query.

Abstract: Roughly described, a database accelerator is installed in a network having client systems which makes database queries to a particular IP address and port, and database servers which accept queries received at an IP address and port. The accelerator includes a cache, and is arranged to receive, through a network port, a database query made by a client system and directed to the particular IP address and port, return response data from the cache if available there, and if not, then forward the query through a network port to the database servers. Upon receipt of response data from the servers, the accelerator can retain it in its cache in addition to forwarding it back to the client. By installing the accelerator transparently in the network, no changes are required to either the client or server software in order to add query caching functionality to an existing client/server database arrangement.

Abstract: This document describes a search retrieval system for automatically indexing data representing audio-visual recordings and for querying, responsive to a search query, that indexed data representing the audio-visual recordings. The search retrieval system defines weights for semantic features of an audio-visual recording and extracts, based on execution of a first set of rules, one or more semantic features. The system determines a weight for each of the one or more semantic features. A search engine searches nodes in the graph of the semantic features to identify one or more logical relationships for the one or more semantic features extracted. The weights for each of the one or more semantic features are adjusted based on the graph. The data is indexed in association with the one or more adjusted weights for the one or more semantic features, respectively.

Abstract: Technologies described reduce the amount of time between requesting content and receiving the requested content. In some embodiments, a client provides a search query. A search result page is generated and, prior to returning the search result page to the client, some or all of the search results are asynchronously pre-fetched and cached. The search query can include custom parameters that are also included in the pre-fetch requests. Web addresses in the search results page can be modified to indicate whether a prefetch operation was initiated. Once a user activates one of the search results, the responding web server uses the cached data while generating a response.
