Patent number 8554730 is assigned to
The following quote was obtained by the news editors from the background information supplied by the inventors: "Databases are computerized information storage and retrieval systems. A relational database management system is a computer database management system (DBMS) that uses relational techniques for storing and retrieving data. An object-oriented programming database is a database that is congruent with the data defined in object classes and subclasses.
"Regardless of the particular architecture, a requesting entity (e.g., an application or the operating system) in a DBMS requests access to a specified database by issuing a database access request. Such requests may include, for instance, simple catalog lookup requests or transactions and combinations of transactions that operate to read, change and add specified records in the database. These requests are often made using high-level query languages such as Structured Query Language (SQL). Upon receiving such a request, the DBMS may execute the request against a corresponding database, and return any result of the execution to the requesting entity."
In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors' summary information for this patent: "Embodiments of the invention provide a method, product and system for performing an operation that includes receiving a request to add a table to a replication domain, such that the table is replicated from a first database server to at least a second database server, where the table includes at least a first record. The operation also includes, responsive to the request, generating a key value for the first record on the first database server. Subsequent to receiving the request, a second record to be inserted into the table on the first database server is received. A key value for the second record on the first database server is then generated. Each generated key value is unique across the replication domain. Further, a column is added to the table to store the generated key values. The column is added without requiring exclusive access to the table."
