· 1.6 What is the policy on updates...how much do they cost?

 

All minor updates are free as of this writing (subject to change). Minor updates are those where the software version number to the right of the decimal change (minor updates usually slightly differs from each other), but the digit to the left of the decimal stays the same. For example, updates from 3.0 to 3.1 are free, however, 2.x to 4.0 will be on a cost basis.

Additionally, if a new major version does get issued, it is offered to our current customers at a discounted rate (50% discount) - it means that to register a major version update you will have to pay only 50% of its total price for each license to be renewed (for instance, $50 USD for one license renewal if the price is $100) to renew your registration.


· 1.7 What are the advantages for distributing patches?

 

Distributing the changes as the "patch" has several significant advantages over distributing new version of the product. First, you don't have to make new CD-ROM's (or multiple floppy disks) and new boxes.

The patches are usually small and easy to distribute on single floppy or over the Internet. Due to the differential nature of the patches, you can also distribute your patches freely (from your web page for example), because it is impossible to install patch without previous (bought and registered) version of product.


· 1.8 What is the difference between patching and incremental updating?

 

Incremental update contains all the files which have been changed between two versions.

DF-files made with DF SDK consists only of the changes from within each individual file with the help of byte-level differencing technology used by our patching engine, resulting in a significantly smaller update size.


 

2. Technical Questions:

 


· 2.1 What is the main idea of building update modules?

The main idea of building patches is that patch file represents only information concerning changes made to an old version software product files relatively to a new version software product files. And if these changes are not significant relatively to total size of new version files than such delivering of update module (patch file/patch module) can become more effective method of update delivering.

Software has its bugs. These bugs are often discovered after the official release of the product. You are getting bug reports from your users. It's terrible that you spent your money to create fancy box, to record CD-ROM's and to distribute your software and several days after they appear. So, you should use "patch" which just contains description of changes you have made to your product since the official (or just previous) release. What's more, the difference between previous and current version to keep the patches as small as possible.


· 2.2 Why patch file size for EXE-files and DLL-files update sometimes appears to be rather large... ?

 

This is so indeed, similar effect can occur sometimes. At recompilation of source code with insignificant changes regarding source code of the old version output file of newer version (EXE, DLL, etc.) most likely will have significant difference comparing with old version files. First of all, it is a result of some features of program binary code representation in Win32/PE executable files.

 

Here are some recommendations to reduce the size of output patch file in this case:

· Try to reduce files size by moving unchanged parts of the program (viz. their invariability from version to version or their insignificant changes) to dll-modules.
· Do not apply Exe-compression utilities to deflate executable files (if there is no extreme necessity).

 

But nevertheless PatchFactory considers all these features of EXE and DLL files and provides optimal patch building in these cases.


· 2.3 I need to update a database with things like adding columns or so. Does your software could help me to patch the database using sql or it can replace old files...?

 

DF SDK does not deal with any specific data structures, it operates with files and directories. Databases or files of other formats can be updated only as binary files (warning: database update can be implemented only if it is not changed on the end-user's machine).


· 2.4 Does the DF SDK require any third-party libraries to run?

 

DF SDK is entirely self-contained: it does not use any 3rd party libraries, and only requires libraries which are part of the base operating system.

With DF SDK, you have the assurance that customers with different hardware and software configurations will always be able to update your software.
