My company is currently using a custom made erp software.It lacks many features ad no more updates are available. So i thought of moving to Odoo which open and free. So how can i work odoo in existing setup. I need to preserve all my previous data and it should be accessible or visible in odoo also.
Help me with database problems that might arise.
This question is probably too broad, but I'll describe what I did to migrate from LedgerSMB to OpenERP 6 back in the day.
OpenERP can import a CSV file for any of its models. I ended up creating PostGresQL queries to export the LedgerSMB data in an OpenERP form with a lot of translations and case statements to produce CSV files that OpenERP would injest. I ended up doing the chart of accounts by hand, and then wrapped all that in a custom module that I added.
The details will be very dependent on the structure of your existing ERP system, but the general approach of doing the transform in the export is reasonably likely to work.

Im wondering for what the SQL database project template exists. I have created one and inserted a table with some col. Now i saved that, so i want to write Into that mdf-file Form a Windows forms project. I dont know how to acces that or even if this SQL project template is ment for that sort of usage. Is this a good solution for a local database?
Sry for that kind or basic question
The database project exists so that you can store the database structure in source control, generate and deploy the database (or upgrade scripts).

I need to prepare a Software Requirements Specification Document for a small enhancement within an JAVA application.
I have tried goggling for the same but found the samples for whole application whereas I am preparing SRS for a small enhancement within an application.
Can anybody suggest the links or suggestions for preparing the SRS.
As you realized by yourself what you're asked isn't a Requirements Specification, which usually covers the whole set of requirements for a software.
What you've been asked is a Change Request, and it must be merged in the existing SRS. However something tells me that there's no SRS for the software you're dealing with, as your management doesn't know the difference between both...

I am pretty new to CoreData Programming but would like to ask:
Do I need to create a database to use CoreData ? Can coredata operate on a simple flat file ?
Please provide suitable references & links.
Thanks in advance
Core Data provides four native types of persistent store:
SQLite
Binary
XML
In-Memory
These store types each offer different benefits and tradeoffs, and are described in “Persistent Store Features”. The Binary and XML stores are "atomic” stores—they must be read and written in their entirety, unlike the SQLite store which can be modified piecemeal, one record at a time if you wish.
Refer to the first link (pdf)

i have developed an ios application (not finished), and know i would like to migrate my project to use core Data, it's this possible ? if yes How ?
without giving any specifics it is difficult to be specific in an answer.
What you need to do is to link to the binary of the CoreData Framework in your solution.
You need to decide which storage you wish to use (sqlite etc). Is the information to be persisted user preferences? Is is a mini database? Is is one flat file store?
At the end of the day you'll need to do some reading based on which of the types of backing store you choose.
Hope this helps as a starting point.

In my app which is data collection app i need offline support. Let's say when i am gathering user's data there is no connection on device but once the device comes in network the whole data should automatically goes to the server.
How should i implement this kind of functionality.
Thanks,
Your question is pretty vague, but I assume you're wondering HOW to persist data and not how to automatically send it to the server.
If the data is very simple, NSUserDefaults may suffice.
If you need a bit more complicated data structures, you can use archives.
If you need to store complex object graphs you need to use Core Data.
There's a pretty good guide explaining all of these here.
