Database Conversion between Database Management Systems

By: Lucie Red


Today many companies determine to publish their data on the Internet trying to expand their business and make their information more accessible. The IT industry proposes a wide range of original solutions for resolving data inconsistency problems that publishers inescapably face when exporting their data as they need to properly access, process and interchange large amounts of information mainly through the web.

Usually, users start from simple desktop database tools and then increasing size of data force them to migrate information to some kind of server databases.
The article will be equally useful both for a newbie and for an experienced publisher. The article covers some critical issues such as database conversion, synchronization, etc. important to know for database administrators, database driven website developers and for all who use database approach in their fields of activity.

Problems and solutions

Generally, DBMSs provide an efficient set of tools that make accessing, organizing, and sharing information easier than ever. Most of them are reliable, fast, and easy to use, with secure and flexible password system that enables host-based verification but to select a right DBMS satisfying the specific needs the publishers should know what problems and possible solutions they can experience working with databases. We suggest three exemplary scenarios below.
Scenario 1:
Small business owners need to categorize their data. For a start it's enough to use some kind of a desktop database. As his business progresses he should handle more data and it becomes necessary to migrate data to a server database system. Generally all server databases are located in the internet thus data migration to server database can help to kill two birds with one stone: multi-user database located on server allows to store and process more data and make it possible to access more users to the same data at a time.
Scenario 2:
A server database contains bulk of data. It's necessary to sort and then process data on a personal computer. Afterwards it is possible to update data on a remote server with information changed on the local computer.
Scenario 3:
Several users input data on their PCs then transfer entered data to the distributed server database. The information entered by users will be accessible for general use after moving to the server. Many organizations have similar databases keeping them updated regularly with the help of synchronization.

Two-way conversion

To manipulate data in the right way and eliminate possible problems a proper database tool should contain a set of required options. Two-way data conversion is one of them.
The result of conversion is identity of the data: all data from the table in source database must be accurately copied in the table of destination database. Due to the lack of time to learn database technology the life of database publisher can be relieved by many useful tools accessible on the market this time.

Synchronization

If you need to keep your database updated make sure that a db conversion tool you'd like to purchase accomplishes synchronization option that will enable your data to be reflected and regularly synchronized between databases. It is a common practice for organizations to have similar or identical databases in many systems. More information about database synchronization you can find here http://www.dbconvert.com/synchronization.php

Preverification of possible conversion errors

Any conversion process is difficult to imagine without any possible data collisions due to the peculiarity of your database structure and its types. Sometimes, it may happen that the general rules of database design are not observed in view of particular requirements. In this case, it is essential to be notified about the program behavior beforehand.
It's quite possible that some errors that could bring to the conflict on a destination database are easy to eliminate by a small reconfiguration of the conversion process issues in one touch.

Data mapping

In general, data mapping is the process of creating data element mappings between two distinct data models. Data mapping is usually used as an additional ability for data population. In other words, data mapping is a compatible data types' assignment for a destination database that makes your conversion more flexible.

Data filtering

Data filtering is the additional feature which performs the most advanced method to export definite data. Appling filters user can set complex conditions and as a result receive complete information according to specific criteria separating all the rest records from a table. The purpose of data filtering is to assist the user in conversion of only needed range of information. More information about data filtering you can find at http://www.dbconvert.com/filtering.php

Getting round the access limitations

Database administrator can deny the access to a database being concerned in protecting the information and avoiding insecure connections. To gain access to a MySQL base you usually need to obtain the permission for connection from your Web hosting provider. For example, in case your IP address is not static (as dialup connection) and changes each time you get on-line your MySQL server administration can reject giving you a direct access to a database. In this situation saving data of a database in a dump file comes into play.

Secure shell (SSH) support

Working with data a trustworthy tool must establish stable connection between platforms and provide secure tunnel for safe and quick data running with optional configurations. Thus, a tool of high quality must support secure shell (SSH), a program that allows a user to log into another computer remotely across the Internet, while maintaining complete security.
SSH is used for port tunneling or forwarding, often as an alternative to a full-blown VPN. What SSH tunneling enables you to do is to transmit all your traffic to the server via your SSH connection.

Automation of the process with scheduler

If scheduling function is available it gives you an opportunity to launch the conversion process on a user required schedule that implies that you can run a program without user interaction. Scheduler enables you to automatically synchronize or convert data regularly without supplementary settings and with the smallest effort. More information about scheduling you can find at http://www.dbconvert.com/dc-scheduler.php

Command line

If you have a task that should be performed by scheduler and all converting parameters are known beforehand then there is no need to open GUI interface. The program should be launched in command line mode. Running the application in command line mode as a service allows a user to work with it even not being logged in.

Conclusion Software products market abounds with various tools providing different solutions. That's why it's very difficult to choose a suitable product that must meet the demands described in this paper. Often publishers face the challenge how to select a conversion tool which can reliably migrate data from one database format to another. Hopefully, this article will help evaluate the right tool you may need when you have a task to transfer data.
In case you consider using specialized db convert applications (http://www.dbconvert.com/) you have a good chance to combine your computer's ability to gather and sort vast amounts of data and the Internet's ability to distribute it globally.
