Question about mimer

Question about mimer

(OP)
Hello,
 
We are developmenting a "who is who" for our company and we need implement this for third generation phones, for example Nokia 6300, in J2ME. This phone don't have any operative system (symbian...). In this case, how can implement one data base in our phone-application? Is it possible with Mimer?
 
If you need any more information, ask me please.
 
Thank in advances
LEI

RE: Question about mimer

Hi.
As you have noticed, Mimer does not offer a database engine component for Nokia 6300 and other J2ME only devices.

What is possible, however, is to develop a J2ME-application which accesses a remote database using the networks that are available to the device (WLAN, GPRS, 3GSM, etc). There are both availability and security considerations to be made. For example, what VPN solutions are supported by Nokia 6300 devices?

RE: Question about mimer

Hi,HondaBoy

    You mean Mimer SQL can't work on phone without OS,for example Symbian or Wince. If we have to use database, there is no way.

    Can you recommend a database which can be supported by cellphone without OS?  

RE: Question about mimer

I am not sure I understand the question. If the question is about J2ME/MIDP cellular phones continue reading at A. If the question is related to other devices without a well-known operating system, continue reading at B.

A. No, the download page at the Mimer website does not list a database server product for J2ME/MIDP environments. It is possible deploy Mimer SQL based applications on J2ME/MIDP but the database backend must be somewhere else outside the Java sandbox.

If you want to store your data inside the J2ME/MIDP environment, you may want to look at javax.microedition.rms package. That API supplies a basic record based dataset functionality that you may use for long term storage. None you features you expect in a database management system is there, but nonetheless you can store your data on a durable medium.

B. As I understand things, you are looking for an off-the-shelf product that will work on a cellular phone with a custom operating system. You wrote "no operating system", but I prefer to use "custom operating system", because no matter what type of device it is, there always has to be some kind of software layer that manages the hardware.

However, if you are using a custom operating system it is very difficult, not to say impossible for vendors to supply off-the-self products for you. At best, you can get access to their products by participating in a porting process to adapt their products to your custom environment.

I am sure Mimer SQL, as well as many other products on the market, can be ported to your environment. If that is easy (=cheap) or difficult (=expensive) depends on the characteristics of your device.

If you want to do the porting yourself, either try downloading any open source database product and start working yourself, or contact the database vendor about licensing the product for your environment.
