    摘要： A method and system for accessing database tables that contain binary large objects (BLOBs) is disclosed. The method includes encapsulating BLOB-based tables with virtual tables, which allows a user to access the content of the BLOBs via SQL. In one example, the virtual table has a generic table structure that consists of columns (e.g., class name, field name, and field value) and information regarding what level of an object hierarchy contains an element. In another example, a user can define the structure of the virtual table by identifying which object attributes to report.

    摘要： Regarding a method for operating an industrial controller, a control program executable in a processor that is arranged in the industrial controller is subdivided into a main block and several program blocks. The program blocks are processed under event control that takes a processing priority into consideration. The processor includes a multi-core processor having a plurality of independent sub-processors. The method includes assigning the main block to a first sub-processor, and executing a part program associated with the main block in the first sub-processor. The method also includes assigning each of the several program blocks to the additional sub-processors, and executing the part programs associated with the program blocks in the respective sub-processors. The method further includes operating a control device to evaluate as input variables the processing priority and an event assigned to the respective program block, and switching the sub-processors into active or inactive state using the evaluation.

    摘要： A method and system for full text search for use during destination selection with a navigation system is disclosed. The method partitions a full text search index based on frequently used terms. These frequently used terms are then mapped to dedicated full text search indexes, where each document contains this frequently used term but the term itself is not stored in the index. A relation maps the frequently used terms to the inverted indexes.

    摘要： A method and system for efficiently storing, retrieving, and updating binary large objects (BLOBs) in embedded systems is disclosed. The metadata of the BLOBs is stored in relational tables, while the BLOBs are stored in a flat file. Querying the metadata of the BLOBs (i.e. the starting points of the BLOBs and their length) is performed based on SQL. The corresponding BLOBs are then accessed using file operation commands. To further simplify the querying and storage of BLOBs, virtual tables are created. By using these virtual tables, a user can access a BLOB as if it was stored in a physical table.

    摘要： A navigation system utilizes a testing package tailor made for an incremental update to a map database. An incorrect incremental update may corrupt a navigation database. Testing an incrementally updated database after updating allows a corrupted database to be detected before the corrupted database is used by the map database system. Map tiles associated with a list of recompiled objects are used to populate a table. A test script is created from the list map tiles and, when executed, checks the validity of references in the map database associated with the map tiles. The test script generates a return value that indicates whether errors occurred, the type of the errors, the quantity of errors, or any combination thereof. The navigation system analyzes the errors and determines whether to finalize or roll back the update.
