Data synchronization involves the establishment of consistency among data from the source to the targeted storage (and vice versa). It also involves the continuous harmonization of the data. There are several tools that you could use for the file synchronization. These include version control tools such as CVS and Subversion, distributed file systems such as Coda, and mirroring such as rsync.
One of the most important benefits of data synchronization is that it makes data available locally. Local availability of data is advantageous over availability through less reliable and often expensive single central databases. These databases are also often faced by the challenge of slow connections. Another advantage of synchronization is that this data will be available locally even when there is no connection to the central database. This means you will not be cut off from your data when there is a power failure, a failure in the network connection, or in the event of any other failure.
Databases usually take up a huge space in your storage device. Synchronizing your data helps you, synchronize it into a smaller data file. This is important because you can then distribute your data to different departments in your company or to different locations, depending on how you have synchronized the data.
Another of the major benefits of synchronizing your data is that the smaller database means that you can upload or download (transfer) files on your Web server and transfer data through other means much faster. The fact that requests are processed on local servers with no requirement for access to wide area networks (WANs) is what makes retrieval rates faster. The faster response times are also due to the fact that local processing means less work for the central database server.
Synchronizing data into the XML format is important in that it helps you make Web applications that can be used to stock reports from offline software databases and to check your sales. The fact that there are several data synchronization technologies means that there is something for everybody. The most popular of these are MobiLink and SQL Remote.
You get greater consistency and data accuracy with data synchronization. This is important because it maintains the integrity of your data over time. You should therefore, synchronize your data on a regular basis. A good synchronization solution gives you native access to different data types in different systems. A good solution will synchronize semi-structured data formats, structured and unstructured data across transactional and operational systems, including mainframes, packaged applications, application integration tools, appliances, databases, and non-relational sources. A good synchronization solution will help with collaboration and reuse across geographies and projects. A good synchronization solution will match and cleanse data before synchronizing and it will provide flexible, granular, and role-based permission management for data security protection, even across corporate firewalls and WANs.
Data Synchronization establishes data consistency from the source to the target storage, and vice versa. There are several reasons why you should synchronize your data.
