In addition, concurrency is increased further by use of run-time information. A performance study is conducted by means of simulation using 007 benchmark. Through the simulation, the proposed technique is then compared with the two existing techniques. The performance studies show that the proposed...
Techniques are described for performing dependency locking to enable parallel execution of database server processes modifying the same object. In an embodiment, a DBMS receives a request to execute an operation on its managed database. The request may include an object identifier and a version ...
You can achieve scalability using many different techniques, including minimizing network traffic, which often manifests itself in the Value Object pattern. Using this pattern, however, raises data integrity issues, which we will address here. This article describes the Optimistic Locking pattern. It ...

Those skilled in the art will also realize that, by utilizing conventional techniques, all or portions of the software's computer-executable instructions may be carried out by a dedicated electronic circuit such as a digital signal processor (“DSP”), programmable logic array (“PLA”), discrete...
More recently, however, there has been a growing trend to use a data warehouse operationally (referred to as a “operational data warehouse” or “real-time data warehouse”), which involves making relatively real-time decisions about data stored in the data warehouse. Traditional techniques of ...
To deploy or release a database with an associated application, a system can perform various database release techniques on the database to ensure that the database is being deployed with updated and correct data. Release scripts can be created, and can include database description language scrip...
