10 results about "Federated databases" patented technology

Techniques and solutions are provided for implementing query constraints. A keyword in a query language is provided that indicates the presence of a constraint. During query execution, if the constraint is not satisfied, the query can be terminated / caused to fail. In some cases, the keyword is introduced into a query by a query optimizer. In a specific example, the keyword is introduced as part of optimizing a query where at least some query operations are performed using a federated database system. The keyword indicating the constraint can be included in a query language statement and sent to the federated database system for execution. If the constraint is not satisfied, the federated database system can send a failure notification to the main database system.

Example solutions for optimizing an initial query execution plan for a federated database includes identifying a group of operations in the initial query execution plan that conform to a recognized pattern including fetching data from a data store. Based on detection of the pattern and of the presence of a condition, an optimized query execution plan is created from the initial query execution plan by replacing the group of operations with a first execution branch and a second execution branch, wherein the optimized query execution plan executes at least one of the first and second execution branches. The first execution branch includes first operations for fetching the data from a first data store and the second execution branch comprise second operations for fetching at least a subset of the data from a second data store.

Introduced here are computer programs and computer-implemented techniques for generating and then managing a federated database that can be used to ascertain the risk in interacting with vendors. At a high level, the federated database allows knowledge regarding the reputation of vendors to be shared amongst different enterprises with which those vendors may interact. A threat detection platform may utilize the federated database when determining how to handle incoming emails from vendors.

The invention belongs to the field of cell culture automation and intelligent regulation and control, and discloses an optogenetics-based adherent cell culture optimization method and system. The method comprises the following steps: inputting an adherent cell type and a culture target, and calling an adherent cell-optical genetic parameter joint database; performing targeted pretreatment on the target adherent cells; processing through a multi-parameter optimization algorithm hardware platform to generate an executable customized photostimulation scheme; performing accurate light stimulation on the positive adherent cells; comparing the obtained detection data with normal adherent cell parameters in a joint database, and evaluating the influence of a photostimulation scheme on the cells; updating the parameters of the multi-parameter optimization algorithm and the prediction model; and inputting the adherent cell type and the culture target to the updated prediction model, and outputting an optimal light stimulation scheme. The core problems of low photostimulation accuracy and poor targeting in the prior art are solved, and high-activity and high-consistency light-sensitive adherent cells are stably produced.

A method of securely accessing a database with sensitive data, such as the clinical information of patients, by a client in a privacy-preserving manner, including: communicating with the server to obtain tags for specific attribute-value pairs when the client is authorized to make a query; imposing a tag quota per client and restricting tag generation to authorized query terms with valid digital signatures from a third-party authority; storing the tags and their associated query terms in confidence for future queries; sending a combination of tags that define the terms of a conjunctive query over a secure channel to a proxy; receiving from the proxy encrypted coefficients of a polynomial whose roots are indices to the query results; decrypting the encrypted coefficients in a first protocol with the server; calculating the roots of the polynomial based upon the decrypted coefficients and discarding any superfluous roots; obtaining the encrypted records associated with the calculated roots from the proxy; and decrypting the encrypted records in a second protocol with the server.

This invention discloses an intelligent identification method, system, and device for quality defects in hardened concrete vibration: A spatiotemporal-process joint database is constructed through data acquisition and annotation; enhanced visual feature vectors are obtained through image preprocessing and feature extraction; knowledge graph vectors are obtained through knowledge graph construction and semantic encoding, generating a unified semantic vector; cross-modal fusion and reasoning are performed to fuse the visual feature vectors and knowledge graph vectors, and the causes and levels of defects are inferred in conjunction with engineering specifications, resulting in fused multimodal features; structured defect description text is generated and optimized through text generation and optimization; based on the optimized defect description text and the original acquired image data, a structured report is generated, and the defect area and reasoning path are visualized on the image. This invention combines computer vision and natural language processing to automatically identify concrete vibration defects and generate structured reports, replacing manual inspection and improving quality control efficiency.

In a particular example, a keyword is introduced as part of an optimized query, where at least some query operations are performed using a federated database system. Keywords indicating the constraints may be included in query language statements and sent to the federated database system for execution. If the constraints are not met, the federated database system may send a failure notification to the primary database system.
