8. A computer-implemented method for managing a database, comprising: maintaining data in a computerized database, said computerized database having data organized in at least one database table; monitoring respective changes made to each database table of said at least one database table; responsive to said monitoring respective changes made to each database table of said at least one database table, determining a respective database table volatility state of each database table of said at least one database table; responsive to determining a respective database table volatility state of each database table of said at least one database table, generating a respective at least one volatility attribute representing the respective database table volatility state of each database table of said at least one database table, wherein the respective database table volatility state of each said database table is a property of the respective database table that is a function of changes to the respective database table with respect to time, independent of any queries against data in the respective database table; and using the respective at least one volatility attribute of each database table to manage data in the respective database table, wherein using the respective at least one volatility attribute of each database table to manage data in the respective database table comprises at least one of: (a) using the respective at least one volatility attribute to determine an optimum query execution strateay for a query against data in the respective database table, (b) using the respective at least one volatility attribute to determine whether to re-optimize a previously saved query execution strateay for a query against data in the respective database table, (c) using the respective at least one volatility attribute to determine whether to collect statistical data regarding the respective database table, and (d) using the respective at least one volatility attribute to manage storage and/or retrieval of data in the respective at least one database table.
8. A computer-implemented method for managing a database, comprising: maintaining data in a computerized database, said computerized database having data organized in at least one database table; monitoring respective changes made to each database table of said at least one database table; responsive to said monitoring respective changes made to each database table of said at least one database table, determining a respective database table volatility state of each database table of said at least one database table; responsive to determining a respective database table volatility state of each database table of said at least one database table, generating a respective at least one volatility attribute representing the respective database table volatility state of each database table of said at least one database table, wherein the respective database table volatility state of each said database table is a property of the respective database table that is a function of changes to the respective database table with respect to time, independent of any queries against data in the respective database table; and using the respective at least one volatility attribute of each database table to manage data in the respective database table, wherein using the respective at least one volatility attribute of each database table to manage data in the respective database table comprises at least one of: (a) using the respective at least one volatility attribute to determine an optimum query execution strateay for a query against data in the respective database table, (b) using the respective at least one volatility attribute to determine whether to re-optimize a previously saved query execution strateay for a query against data in the respective database table, (c) using the respective at least one volatility attribute to determine whether to collect statistical data regarding the respective database table, and (d) using the respective at least one volatility attribute to manage storage and/or retrieval of data in the respective at least one database table. 11. The computer-implemented method for managing a database of claim 8 , wherein said determining a respective database table volatility state of each database table comprises computing a respective figure of merit representing volatility, said figure of merit using at least one of: (a) a number of insert operations performed on the respective database table; (b) a number of update operations performed on the respective database table; (c) a number of delete operations performed on the respective database table; (d) a size of the respective database table; (e) a change in size of the respective database table; and (f) a number of bytes altered in the respective database table.
