Address mapping
Background/motivation
Currently there are some issues, which mainly rose from our decision to avoid the customer level:
- we cannot generate invoices to other than the contract address ⇒ so we need an invoice address, e.g. in extending the contract database table/MVC
- there is no explicite possibility to have more than one contract per customer – and doing so implicit will probably raise problems with Envia API
- the existence of modems (holding the installation address) is not mandatory – Andre mentioned switch-port depending systems and TR-069 configurations
- is it better to avoid address data in this level of our system?
- if e.g. the installation address is placed here then we will need an abstract layer (even if there is no physical expression) only to keep this data
Current mappings
iDocsis | “legacy” km3 system | EnviaTEL |
---|---|---|
contract⇒address | customer⇒address (used as invoice address) | customer⇒address (Envia customerreference also stored in contract table) |
modem⇒address | contract⇒address (used as installation address) | contract⇒installation_address (Envia contractreference also stored in contract table) |
n/a | modem⇒address | ?? |
Decisions to make
Shall we keep the current structure or switch to “legacy” system's structure?
- current structure has its weak points (see above)
- I think
- switching would be imply a great effort (especially for modules billing and provvoipenvia)
- if we decide to switch we should do this soon
- not trivial to convert existing databases (maybe there is some manual work (or supervision) necessary
- the later the switch, the bigger the implementation costs
- if we decide to switch we should do this soon
Where to put the installation address? Shall we allow more than one modem/installation address per contract?
- This is not as trivial as it seems – there ere several things to consider:
- handling of the contracts the customer signs – there should be pieces of paper for differing installation addresses and changes of these addresses
- people that hack this data into the system have to pay attention to the addresses
- the installation address will be used to guide ambulances
- there has to be a doorbell panel with the “name” from installation address
- to be continued
