An interface for users to gain access and manipulate unstructured data is provided. In response to receiving a user query associated with a first database format, a system can request unstructured data associated with a second database format from a second database. The unstructured data can include a set of data groups where each data group has a set of values. Each value can be associated with a different tag. To generate a structured database, some embodiments can determine the number of data groups and the number of unique tags across the data groups and populate the table with data from the unstructured data. Subsequently, the system can apply the user query to the table to obtain a query result and transmit the query result to the user device.

A method of computing a join pattern agnostic aggregate function includes loading source code and parsing the source code to identify different database query operations. In response to the identification of an aggregate function in one of the different database query operations in which records in multiple tables are joined together in a table join, a multiplicity of primary keys are retrieved, each corresponding to a different one of the multiple tables and also an object of one of the tables referenced by the identified aggregate function. An existence of a fan out condition associated with the table join is then computed. On condition that an existence of the fan out condition is not computed a non-fan out sensitive implementation of the aggregate function is invoked with respect to the object. But, otherwise, a different, fan-out sensitive implementation of the aggregate function is invoked with respect to the object.

A method and system is provided for classifying and labeling information content and also for profiling a user for accessing the information content, both using a coordinated labeling technique so that content from multiple sources may be searched, identified and/or presented to the user according to the user's profile. This technique provides an ongoing update of information content and sources while filtering out unnecessary information that is irrelevant to the user's profile, resulting in focused availability of information to the user. The user profile is matched with content of interest and matching content information may automatically be updated and made available to a user, in conformity with the user's profile. Content providers may now jointly use a common labeling scheme to improve the experience of their users and to provide content providers a technique to associate users with common facets of classification.

A reliable and scalable data repository service can be supporting cooperative transactions. In an example, multiple data producers may use the data repository service to upload data in one or more transactions. Data contained in one transaction may be treated as an atomic unit. In an embodiment, the data repository service manages multiple candidate transactions associated with an election transaction such that at most one candidate transaction may begin and/or commit a given time. During a commit of a candidate transaction, the data uploaded during the candidate transaction may become associated with the election transaction. The data repository service may maintain metadata associated with each of the candidate transactions. In response to a request for data associated with the election transaction, the metadata may be used, in conjunction with a user-specified isolation level, to locate the data uploaded some of the candidate transactions for the election transaction.

An apparatus acquires a first input-table, based on target table information, and acquires a script for generating a first output-table from the first input-table, and a constraint condition between columns included in the first input-table and the first output-table. The apparatus converts the first input-table into a second input-table such that the second input-table obtained by converting a column structure of the first input-table and a second output-table to be obtained by converting a column structure of the target table comply with the constraint condition, and generates assignment information indicating a correspondence relationship between columns to be included in the second output-table and the target table. The apparatus generates the second output-table from the script and the second input-table, and converts the second output-table into the target table, based on the assignment information.

A storage engine may implement dynamic splitting of contentious data pages. Data pages may store data for a table of a data store as part of an indexing structure for the table. Access to the table may be provided by locating the corresponding data pages via the indexing structure. Access contention for different data pages may be monitored. Data pages may be identified for splitting based on the monitoring. A split operation for an identified data page may be formed to store the data on the identified data page on two different data pages so that subsequent access requests for the data are divided between the two data pages. Monitoring of access contention may also be performed to identify data pages for merging in order to consolidate access requests to a single data page.

Systems and techniques are provided for a decentralized database associating public keys and communications addresses. A signed secret message may be sent by a validator computing device of a peer-to-peer network for a decentralized database to a communications address from a request for verification entry in a verification queue of the decentralized database. A second request for verification including the communications address and a user-signed secret message may be received. The user-signed secret message may be verified using a public key from the request for verification entry in the verification queue. The communications address and public key may be written to a verified database of the decentralized database when verifying the user-signed secret message causes a number of user-signed secret messages received in requests for verification with the communications address and successfully verified to meet a threshold number.

One or more techniques and/or systems are provided for detecting stale data and/or changed data. For example, a bitmap file may be maintained and mapped to an inofile describing various states of files of a file system. The bitmap file may be populated with bitmap records indicating whether files were accessed, modified, or have other states. The bitmap file may efficiently convey information used to determine whether files have not been accessed recently (e.g., stale data) or were recently modified (e.g., changed data) compared to the inofile because the bitmap file may comprise a fraction of the size of the inofile (e.g., a byte of information may be used to represent various states of one or more files). In this way, instead of evaluating a relatively larger inofile, the bitmap file may be evaluated to efficiently identify stale data for deletion or destaging and/or changed data for backup.

An optical electromagnetic radiation (EM) emitter and receiver are located upon a printed circuit board (PCB) glass security layer. A predetermined reference flux or interference pattern, respectively, is an expected flux or reflection pattern of EM emitted from the EM emitter, transmitted by the glass security layer, and received by the EM receiver. When the PCB is subject to an unauthorized access thereof the optical EM transmitted by glass security layer is altered. An optical monitoring device that monitors the flux or interference pattern of the optical EM received by the EM receiver detects a change in flux or interference pattern, in relation to the reference flux or reference interference pattern, respectively, and passes a tamper signal to one or more computer system devices to respond to the unauthorized access. For example, one or more cryptographic adapter card or computer system functions or secured crypto components may be disabled.
