All  types  of  organisations  as  diverse  as  maritime,  oil  &  gas,  utilities  and  defence  use  our  solutions  to  deliver  secure  and  robust  data  frameworks,  many  in  exacting  environments.  

Enables  enterprises  to  distribute  data  from  existing  databases  to  remote  offices  and  mobile  workers  where  connectivity  may  be  intermittent  or  unavailable.    DataXtend  RE  (DXRE)  enables  enterprises  to  distribute  data  from  existing  enterprise  databases  to  remote  offices  and  mobile  workers,  providing  corporate-­‐level  quality  of  service  all  the  way  to  the  “edge”  of  the  enterprise  where  connectivity  may  be  intermittent  or  unavailable.    DXRE  provides  essential  capabilities  for  managing  distributed  databases,  whether  your  enterprise  needs  simple  data  replication  or  a  complete  synchronisation  solution.  With  DXRE,  users  don’t  have  to  be  connected  to  a  network  to  access  data.  Remote  offices  with  limited  or  variable  bandwidth  and  mobile  users  with  limited  periods  of  connectivity  can  both  obtain  the  same  quality  of  service  levels,  optimised  performance  and  lower  management  costs  as  those  in  the  corporate  office.      DXRE  enables  companies  to  manage  data  across  multiple  sites,  geographies,  platforms,  or  database  management  systems,  through  its  unique  patented  technology  for  two-­‐way,  read-­‐write  replication  of  databases.  The  DXRE  distributed  enterprise  is  managed  centrally  but  all  distributed  databases  are  synchronised  transparently  with  the  central  servers.  This  makes  deploying  and  supporting  distributed  applications  as  cost  effective  as  web-­‐based  applications  but  without  the  network  limitations  associated  with  accessing  a  centralised  server  and  database.    Constructing  a  distributed  enterprise  with  the  DXRE  eliminates  traditional  distributed  solutions.

DataXtend  RE  (DXRE)  

 No  application  redesign    DataXtend  RE  allows  you  to  communicate  with  the  database  as  you  normally  would,  using  any  programming  language  currently  in  use.  The  result  is  that  no  application  changes  are  needed  to  access  the  database.    

 And  because  DataXtend  RE  uses  “update  everywhere”  technology,  no  application  changes  need  to  be  made  in  order  to  update  data.    Minimal  bandwidth  utilization  DataXtend  RE  uses  a  “net  change”  model,  so  only  the  data  that  has  been  updated  since  the  last  replication  is  sent  through  the  network.  Additionally,  DataXtend  RE  technology  allows  you  to  partition  data  so  that  only  the  information  pertinent  to  that  site  is  sent  through  the  network.      Low  Maintenance  DataXtend  RE  uses  “live”  database  access  during  replication  sessions,  so  no  synchronization  is  needed  and  there  are  no  log  files  to  manage.  DataXtend  RE-­‐based  applications  can  operate  in  a  disconnected  environment  for  extended  periods  with  no  additional  maintenance  requirements.    Other  replication  solutions  require  extensive  administrative  intervention  to  resolve  data  conflicts.  This  is  because  the  typical  unit  of  replication  is  an  entire  data  record.    DataXtend  RE  technology  allows  administrators  to  partition  records  by  update  authority,  allowing  simultaneous  updates  when  it  complies  with  your  business  rules  and  avoiding  false  conflicts.      Databases   SQL  Server,  Oracle,  Informix,  DB2,  Sybase  ASE,
