Abstract: Disclosed are systems and methods that allow a database engine to access a non-relational document database and dynamically apply a schema that maps documents comprising semi-structured data into a relational data structure. In embodiments, mapping may be accomplished by parsing and analyzing a set of sample documents to empirically generate a normalized tabular schema. In embodiments, the schema accommodates format evolution and variability of documents having different structures and different sets of attributes is automatically executed in a background process without requiring user involvement. This normalization process eliminates the need to create unique modeling languages for semi-structured data. In embodiments, an SQL dialect may be used to join query results and combine the resulting document data with tables from different dimensional or relational databases to generate a combined result without the need to create additional temporary tables for non-conforming documents.

Abstract: In one embodiment, a method includes defining a slice of a dimensional database. The slice includes at least one dimension and at least one measurement and is expressable as a table. The method further includes building, in a structured query language (SQL) dialect, a single query that queries the slice and one or more non-dimensional databases. The SQL dialect represents the at least one dimension, the at least one measurement, and data attributes of the one or more non-dimensional databases. In addition, the method includes parsing the single query. The parsing includes generating a dimensional query for the dimensional database and a non-dimensional query for each of the one or more non-dimensional databases. Furthermore, the method includes executing the dimensional query on the dimensional database. Moreover, the method includes, for each non-dimensional database of the one or more non-dimensional databases, executing the non-dimensional query on the non-dimensional database.

Abstract: A system, method, and computer-readable medium for performing a predictive caching operation in which a hit rate is improved by pre executing statements that are predicted based upon previous use patterns. More specifically, by analyzing a stream of statements provided to a server, such as a database server, patterns of usage are detected and based upon these patterns, statements provided to the server are executed before the actual application executes the predicted statements. Thus the application executes faster because the data requested is already cached based upon the predictive execution.

Abstract: In one embodiment, a method includes enrolling a supplicant device as an authentication factor for a user. The enrolling includes storing a public key of an asymmetric key pair generated by an authentication application on the supplicant device.
