Abstract: A computer implemented method for manipulating data comprises receiving log transaction information from a primary database system at a secondary database system and parsing the log transaction information to identify data objects that have been modified on the primary database system. The secondary database system determines whether the data objects are present in main memory on the secondary database system and whether the log transaction corresponds to a data manipulation language (DML) query or a data definition language (DDL) query. If the data objects are not in the main memory and the query is a DML query, they are copied from persistence data volumes to the main memory. The data objects in main memory are modified by replaying the log transactions on the data objects in the main memory. Then, the data objects in the persistence data volumes are modified. Related apparatus, systems, techniques and articles are also described.

Abstract: An approach for generating an index in Darwin Information Typing Architecture (DITA) source files. The approach determines one or more similar index entries of a prioritized index. The approach determines a fraternal association exists between at least two of the one or more similar index entries when at least one of the one or more similar index entries occur with one or more similar high priority index entries. Responsive to a determination that a fraternal association exists between at least two of the one or more similar index entries, the approach determines whether an inheritance from a parent exists. The approach determines based, at least in part, on whether a fraternal association exists and whether an inheritance from a parent exists, a Darwin Information Typing Architecture (DITA) index.

Abstract: Systems and methods for accessing single-tenant databases comprising a multi-tenant aware cluster manager in communication with instances of single-tenant databases are described. The cluster manager can establish a uniform resource locator (URL) unique for each tenant to access the cluster manager. Each of the instances of single-tenant databases can include data for a corresponding tenant. The cluster manager can receive a request from a client to access a database corresponding to the first tenant. The request can include the URL established for the first tenant. The cluster manager can identify the first tenant based on the URL of the request. The cluster manager can obtain, responsive to identification of the first tenant, a tenant context of the first tenant from a storage. The cluster manager can access, using the first tenant context and responsive to the request, a first instance of the single-tenant databases corresponding to the first tenant.

Abstract: A method and system of correlating annotations of media files. A first media file is received from a first media recording device. A file record for the first media file is created in the file table. A determination is made whether the first media file belongs to an existing matter group. Upon determining that the first media file belongs to an existing matter group: the file record is related with the existing matter group in the file table; annotations of the first media file that are flagged to be shared, are related to all media files of the existing matter group; and annotations of all the media files of the existing matter group to the first media file are related. Upon determining that the first media file does not belong to an existing matter group, a new matter group is created for the first media file in the matter table of the central server.

Abstract: Systems and methods for data management using tagging rules and/or policies. The systems and methods described herein may allow users or administrators to easily label data, so as to organize the data in using any suitable terminology or parameters. Tagging rules (or tag rules) may apply or assign one or more tags to a data file or object. A tag may relate to various components of the data file or object. For example, a tag may relate to a creation date, author, size, or information within the data, such as whether the file or object includes a picture. Once the data is associated with one or more tags, policies may determine how the data is manipulated, stored, accessed, or otherwise used. Policies may relate to actions or operations to be performed with respect to data having one or more particular tags.

Abstract: In one embodiment, a deduplicating storage system includes a processor and logic integrated with and/or executable by the processor. The logic is configured to cause the processor to perform a method which includes: computing a fingerprint of a data chunk, and determining whether a short term dictionary corresponding to the namespace comprises an entry corresponding to the fingerprint. In response to determining the short term dictionary does not comprise the entry, a determination is made whether a long term dictionary corresponding to the namespace comprises the entry. In response to determining the long term dictionary comprises the entry: the data chunk is written to the data store in the deduplicating manner, and the short term dictionary is repopulated with the entry. Moreover, in response to determining the long term dictionary does not comprise the entry, the data chunk is written to the data store in a non-deduplicating manner.

Abstract: The systems and methods described here can reduce the storage space required (memory and/or disk) to store certain types of data, provide efficient (fast) creation, modification and retrieval of such data, and support such data within the framework of a multi-version database. In some embodiments, the systems and methods can store each field of a set of records as a vector of values, e.g., a data vector. A set of records can be represented using a vector hash vector, or “vhash” vector, wherein each element of the vhash vector contains a unique identifier of a data vector, based on a cryptographic hash of the data vector. A header table can store associations between labels and “vhash” vectors that pertain to those labels. Identical data vectors can be re-used between different record sets or vhash vectors needing that vector, thus saving space.
