Sadas Engine is an alternative to databases such as Oracle, DB2 and Teradata, and it is the best columnar Database Management System on the market. Why?
SPEED: it is from 10 to more than 100 times faster than transactional DBMSs, carrying out searches on data in fractions of a second over a period longer than 10 years.
BIG DATA: it can store, manage and analyze limitless quantities of data without consequences on performances.
LOW TCO: it runs perfectly on low cost standard hardware, it does not need DBA interventions and it is completely built in house, so third-party licenses are unnecessary!
Thanks to the performances of SADAS DBMS, an important banking institution has implemented the DWH and allows the users an easy and immediate access to company data. Total number of uploaded records 46 billions Biggest historical table 1,3 billions Daily updated records from 4 to 6 billions Number of Databases 188 Tables per single…
Insertion of the Hints to customize the queries execution modality. Hints are comments that can be inserted in the string containing the query and that are able to change the behavior of Sadas Engine. The behavior of the engine is influenced by the hint only for the execution of the query containing it. Moreover the…
Optimization of the Intraquery parallelism (parallelism to optimize the performances of the single query) and Interquery parallelism (parallelism to optimize the performances of the engine with concurrent queries). Action points: • Improvement of the Heap management to reduce the negative effects of the Heap Contention (frequent concurrent requests of dynamic allocation of memory segments from…
COMMUNICATION ENCRYPTING
Communication between Sadas client and server takes place on proprietary application protocol based on Berkeley Sockets and TCP / IP transport layer with an unencrypted message exchange. Increasingly high levels of security require that data are protected from intrusions at all stages of a process.
It is therefore necessary to implement encrypted communication between client and server with the highest levels of state-of-the-art security. At the same time, particular attention must be paid to the performance of the encryption / decryption algorithms because they could negatively affect the overall performance of the system.
NEW LIKE INDICES
The features of Sadas are essentially based on the massive use of specialized indexes for specific operators of the access plans of a query.
The research activity carried out in collaboration with the University of Pisa led to the prototyping of a specialized index for searches with the LIKE operator, the Suffix Array Index, used effectively in searches on unstructured information by search engines.
