Order chronicle process and method

Abstract

A process for chronicling a portion of an electronic market includes a record process for recording an activity relating to a security interest in an order book in main memory of a computer system and another record process for recording the activity in a persistent store.

What is claimed is:  
     
         1 . A process for chronicling a portion of an electronic market comprises: 
 a first record process for recording a first activity relating to a security interest in an order book in main memory of a computer system; and    a second record process for recording the first activity in a persistent store.    
     
     
         2 . The process of  claim 1  wherein the main memory is random access memory.  
     
     
         3 . The process of  claim 1  wherein the main memory is a cache.  
     
     
         4 . The process  claim 1  wherein the first record process and the second record process record the first activity prior to recording a second activity.  
     
     
         5 . The process of  claim 1  wherein the first record process and the second record process record the first activity within a number of clock cycles.  
     
     
         6 . The process of  claim 1  wherein the main memory is separate from the persistent store.  
     
     
         7 . The process of  claim 1  wherein the persistent store is a sequential access storage device.  
     
     
         8 . The process of  claim 1  wherein the persistent store is a hard disk drive.  
     
     
         9 . The process of  claim 1  wherein the first activity includes matching a security transaction against a portion of the security interest.  
     
     
         10 . The process of  claim 1  wherein the first activity includes executing a security transaction against a portion of the security interest.  
     
     
         11 . The process of  claim 1  wherein the persistent store is used to rebuild the order book.  
     
     
         12 . The process of  claim 1  wherein the state of the order book represents the existing market at the time of the first activity.  
     
     
         13 . A method for chronicling a portion of an electronic market comprises: 
 recording a first activity relating to a security interest in an order book in main memory of a computer system; and    recording the first activity in a persistent store.    
     
     
         14 . The method of  claim 13  wherein the main memory is random access memory.  
     
     
         15 . The method of  claim 14  wherein the main memory is a cache.  
     
     
         16 . The method of  claim 13  wherein recording the first activity in the main memory and the persistent store is prior to recording a second activity.  
     
     
         17 . The method of  claim 13  wherein the first activity is recorded in the order book and persistent store within a number of clock cycles.  
     
     
         18 . The method of  claim 13  wherein the random access memory is separate from the persistent store.  
     
     
         19 . The method of  claim 13  wherein the persistent store is a sequential storage device.  
     
     
         20 . The method of  claim 13  wherein the persistent store is a hard disk drive.  
     
     
         21 . The method of  claim 13  wherein the first activity includes matching a security transaction against a portion of the security interest.  
     
     
         22 . The method of  claim 13  wherein the first activity includes executing a security transaction against a portion of the security interest.  
     
     
         23 . The method of  claim 13  wherein the persistent store is used to rebuild the order book.  
     
     
         24 . The method of  claim 13  wherein the state of the order book represents the existing market at the time of the first activity.  
     
     
         25 . A computer program product residing on a computer readable medium for chronicling a portion of an electronic market, comprises instructions for causing a computer to: 
 record a first activity relating to a security interest in an order book residing in main memory of a computer system; and    record the first activity in a persistent store.    
     
     
         26 . The computer program product of  claim 25  wherein the main memory is random access memory.  
     
     
         27 . The computer program product of  claim 25  wherein the main memory is a cache.  
     
     
         28 . The computer program product of  claim 25  wherein the first activity is recorded in the order book and the persistent store prior to recording a second activity.  
     
     
         29 . The computer program product of  claim 25  wherein the first activity is recorded within a number of clock cycles.  
     
     
         30 . The computer program product of  claim 25  wherein the main memory is separate from the persistent store.  
     
     
         31 . The computer program product of  claim 25  wherein the persistent store is a sequential storage device.  
     
     
         32 . The computer program product of  claim 25  wherein the persistent store is a hard disk drive.  
     
     
         33 . The computer program product of  claim 25  wherein the first activity includes matching a security transaction against a portion of the security interest.  
     
     
         34 . The computer program product of  claim 25  wherein the first activity includes executing a security transaction against a portion of the security interest.  
     
     
         35 . The computer program product of  claim 25  wherein the persistent store is used to rebuild the order book.  
     
     
         36 . The computer program product of  claim 25  wherein the state of the order book represents the existing market at the time of the first activity.
