A method and apparatus for converting code-description table data to an enumerated data type in a schema record referencing the code-description table. A record of a table is identified that references the code-description table, and a portion of a schema describing the record is updated to include the relevant data of the code-description table as an enumerated type of the record schema. The enumerated type schema element includes data elements of the code-description table relevant to the record, each element having its own type. As additional records of the same table that are related to the code-description table are called, the enumerated type schema element may be updated to include additional code-description table data elements.

Emulation of code-description tables on SQL databases using Enum data type

A method and apparatus for automatic schema detection and migration is disclosed. In embodiments, a file including NoSQL data is received and one or more data types are detected in a hierarchical data table description. Within a record of the NoSQL data, which may be stored in a JSON format, a field name and its data type, are stored in a schema describing the data table. As additional records are parsed, the schema is updated to include additional field names and data types, and may include designations such as repeated and optional, for some fields. In embodiments, the schema is a serialized data format, such as Google Protocol Buffers (Protobuf).

Automatic flexible schema detection and migration

A data storage device that, in a first mode, emulates a Wi-Fi adapter to facilitate communication with the host device. When the data storage device is connected to the host device, a processor of the data storage device emulates a Wi-Fi adapter to the connected host device. This includes emulating a Wi-Fi network. Responsive to a request to join the Wi-Fi network, a further notification is sent to trigger a captive portal displayed at the host device. The captive portal facilitates additional communication between the data storage device and the host device. The additional communication can be related to one or more of authentication, access control, firmware updates, and configuration of the data storage device. The data storage device also includes storage medium that, in a second mode, is accessible by the host device.

Communication with a data storage device using an emulated Wi-Fi captive portal

A method and apparatus for carrying out a database select, or query, on a data storage device, upon data stored on that device. Data is received from a host and compressed on the data storage device using a compression code developed on the data storage device for the data. When the host issues a database select request on the compressed data, the compression code is distributed to processing cores of the data storage device and compiled, including the select request, into machine code. The machine code is used to decompress the compressed data while filtering the data with the select request. The filtering result is returned to the host.

Query compiler for record filtering

A method and apparatus for a database management architecture on an SSD. A list of tables is stored in the SSD, and records of a table are stored across multiple FIMs of the SSD such that a group of records may be read in parallel by concurrently reading from multiple FIMs. The records of the table are stored on jumboblocks, organized in an unordered fashion as a linked list. New records are added to the end of the linked list. Records having gaps resulting from data modification or bad portions of an NVM die are re-organized via garbage collection when the gap memory size reaches about 20% of table memory size.

Data storage device database management architecture

A method comprises receiving a set of content items comprising a first content item from one or more media devices via a network, transmitting the first content item to a host device for performance of enhancement tasks related to the first content item, receiving a first enhanced content item comprising the first content item and added metadata from the host device, and storing the first content item and the added metadata.

Assisted multimedia content enhancement

Various apparatuses, systems, methods, and media are disclosed to provide wired communication interface with common mode voltage adjustment for high bit rate communication between devices. In one example, a high speed data communication interface can split the input signal into a high frequency component and a low frequency component. The high speed data communication interface can adjust the common mode voltage using the low frequency component and combine the high frequency component and the low frequency component by superposition after adjusting the common mode voltage.

High bit rate communication interface with common mode voltage adjustment

A method and apparatus for the increase of internal data throughput and processing capability for SSD's, to enable processing of database commands on an SSD. A front-end ASIC is provided with 256 to 512 RISC processing cores to enable decomposition and parallelization of host commands to front-end module (FM) ASICs that each in turn are coupled to multiple NVM dies, as well as processing of host database operations such as insert, select, update, and delete. Each FM ASIC is architected to increase parity bits to 33.3% of NVM data, and process parity data with 14 LDPC's. By increasing the parity bits to 33.3%, BER is reduced, power consumption is reduced, and data throughput within the SSD is increased.

High throughput, low power, high parity architecture for database SSD

A storage system and method for using memory allocated in a host for read data as a host memory buffer are provided. In one embodiment, a controller of a storage system receives a read request from a host for data stored in the memory, wherein the read request identifies a storage location in the host that is allocated by the host to store the requested data after it is received from the storage system. Prior to sending the requested data to the host, the storage system uses the allocated storage location in the host as a host memory buffer to store other data until the host needs the allocated storage location to store the requested data. Other embodiments are provided.

The present disclosure generally relates to a translucid access method and apparatus to a host allowing access to data contained within the host.

Translucid access to storage devices

A system and a method for automatically analyzing and reading a barcode present in an electronically stored and transferred file, and/or printed on a printable substrate, such as a sheet of paper. Such a barcode can be used to store a large amount of information in a small area. Various uses of the disclosed system and method are possible, for example in order to authenticate and/or identify a document. In addition, such a barcode could be used to transmit information which could be automatically read and analyzed. This provides a single solution to the combined problems of data authentication and verification for electronically stored and transferred data, as well as of automatic reading and analysis of data printed on a printable substrate. Although the implementation in which the data is printed onto paper or other physical substrate material is particularly preferred, the overall flexibility of the disclosed system and method enable them to be employed in a variety of embodiments.
