Abstract: Identifying data within a data store satisfying a request. A quantity of the identified data is greater than a threshold. The identified data is analyzed to produce an initial result set with a reduced data quantity including information summarizing the identified data. The analyzing includes visualizing the information summarizing the identified data as one or more graphical displays rendered within a user interface and selectively filtering the identified data based upon a selection of filter factors associated with the identified data to generate an initial result set having a smaller size in relation to the identified data set. Each of one or more succeeding result sets are generated from a corresponding prior result set until a succeeding result set includes a quantity of data satisfying the threshold. The generating of each succeeding result set includes filtering the corresponding prior result set and information summarizing the filtered result set.

Abstract: In accordance with an embodiment, systems and methods can provide for load, aggregate, and batch calculation in a multidimensional database environment. Metadata can be used to identify in which higher dimensions each leaf-level load is used. At such time, the data from the leaf level is aggregated to each of the higher dimensions where it is to be used. Then, the aggregate values are stored in memory until a completed sum (or other calculation) is completed at the higher levels. At such time, the aggregate values can be discarded from memory. The ability of the system to perform a load, aggregate, and batch calculation in one scan is particularly useful in processing very large sets of data, for example in big data environments, where it may not be desirable to load the data for all of the leaf nodes into current memory.

In response to determining to access the one or more key-value records, the database server may access the one or more key-value records in the volatile memory.

Abstract: Technologies are disclosed for computing heavy hitter histograms using locally private randomization. Under this strategy, “agents” can each hold a “type” derived from a large dictionary. By performing an algorithm, an estimate of the distribution of data can be obtained. Two algorithms implement embodiments for performing methods involving differential privacy for one or more users, and usually are run in the local model. This means that information is collected from the agents with added noise to hide the agents' individual contributions to the histogram. The result is an accurate enough estimate of the histogram for commercial or other applications relating to the data collection of one or more agents. Specifically, the proposed algorithms improve on the performance (measured in computation and memory requirements at the server and the agent, as well as communication volume) of previously solutions.

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 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.

In response, the system can increase server tolerance in a systematic way to deal with DDoS by adjusting server settings appropriately.

Abstract: An online computer system including a database uses an encrypted table that allows for write protection its contents. Middleware logic operating on the system acts as an interface for access to the database, so that any business logic on the system accesses the database through simple procedural calls to the middleware rather than directly to the database itself. The middleware logic abstracts logic that helps implement write protection with the encrypted table. Data to be encrypted that has been traditionally written to other tables is migrated to the encrypted table, where the data encrypted using an authenticated encryption with additional data (AEAD) algorithm. To implement AEAD, the original table, column, and primary key indicating where the data would have otherwise been stored are together used as additional authenticated data (AAD). This tuple of information is also stored in the encrypted table.

The method forwards the incoming data to the particular application when the particular application is available, and forwards the incoming data to a data storage to be buffered when the particular application is unavailable for receiving the incoming data.

Abstract: Attributes and semantics of duplicate insignificance that are inherent or inferred in a database language statement are detected. Also, a join operation that is inherent or inferred in the database language statement is detected and examined for join semantics. The join semantics specifies or refers to a driving table to be subjected to a hash join operation that may populate one or more hash buckets. The optimizer and the execution layers may use cost estimation or heuristics to assign the left and right table roles to the tables involved in the join. The hash join operation removes left table duplicates during population of the hash buckets, resulting in full or partial duplicate elimination that occurs during the hash join operation.
