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 method and system for full text search during destination selection using a navigation system is disclosed. The full text search system includes a relation table and a spatial index structure, e.g., an R-tree. The relation table maps tokens to a token identifier. Each level of a destination is mapped to its own dimension, e.g., Country to X, City to Y, and Street to Z. Each document is then mapped to an n-dimensional vector using the token identifiers.

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.

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 page server and method of using the page server is described. The page server stores versioned pages. The pages, which are equally sized data chunks, can be stored with identifiers and version data in a relational database, in separate files, or in a single file where pages are concatenated. The page server may be accessed via SQL, a web interface, a proprietary key/value/version interface on top of TCP/IP, or other method. The page server facilitates incremental updates.

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.
