Visual Dataflex is a database RAD (Rapid Application Development) of Visual Studio, where Windows and Web database interface applications can be designed.
~ ~ The best kept secret in database development
This article is for viewing by medium and small companies to lower costs and more rapid alternative to Microsoft platforms such as. NET and VB meant.

==================================
In 1981, together with DBASE2, FoxPro, etc. DATAFLEX (the DOS version)Commission initiated the 2.3 version for DOS, CPM and UNIX.Because It was the highest price database engine and development platform, and it's specs outweighed the competition of many individuals who are not programmers, and with it bought DATAFLEX English is similar syntax has been faithful and a lot of success stories were created. If you are an accountant, sales manager, or inventory were analyst, DATAFLEX was perfect because it addresses a 4GL product and the interface with the database in thePackage for you automatically, and a combination of skills and simple database-development have been combined to v2.3 is a very successful endeavor. The packages were employed during this time written by experts in the field, and while many unorthodox method was, it worked! Unfortunately, like so many others, was (now) written for DOS legacy systems more and more difficult to implement and maintain, as Windows was introduced. There are many applications still DOS DATAFLEX refueling companythroughout the world and most are now under consideration: Port Visual DataFlex or port to the Web? The biggest concern for many companies is that unique and proven code that runs like lightning through eithe of these solutions in question, and is usually a real concern, however, carry much less important than the users.
* What are the advantages it has over. NET and VB?
Imagine a designer of software and a. NET solution from Microsoftavailable. First, start with the user interface and the tools to create an interface in Windows / web are very attractive. Then you have the job of writing an interface to the data, a huge undertaking, requiring thousands of lines of code to achieve a stable application that the specifications of the database table, business rules, links between database tables (dependencies, etc.) is to . produce
Now imagine a designer Visual DataFlex. First start by subclassesThe controls by Data Access Worldwide (true Windows controls provided) and leave those sub (on the name of your company is based, for example) completely alone and without change .... But for future reference. Then open the database, the builders created datadictionaries for each database table in your project, the database relate to each other rules (automatically generated) and determine how each column of each table is shown in which the validation is applied to it, and make Your business rulesin the class for the table.
See how the two approaches are completely the opposite?
Visual DataFlex centralized data validation, finding, clearing, deleting, and Save, and click the Visual Studio to create the visual part of the program are connected by built is those on a tree data dictionary objects (instantiated business rules based on layers of classes), the business rule exceptions and can cause augmentation.
The benefits seemimmediately:
1, Data Integrity and business rule layers intertwine and to validate the data (generated automatically based on your validation rules) and sync together to save a record or records.
2nd The visual designer has the same classes as for the most part. NET and VB, but they are defined in the database connected and immediately take a save / delete / delete / validation / find operations, need not be compatible.
The combination of these twoBenefits means that your data integrity is higher, your data operations are eloquent, and the interface (visually appealing, while not quite as beautiful as. NET).
The design and implementation of the time from beginning to end is less than. NET from an estimated 40%, resulting in lower costs to your customers and more bids for you.
* What should I try Visual DataFlex (download eval)?
First, from the above, you can see how a database approachsignificantly easier than other options. Do not download VDF, a game program! It is built for business applications as a specialty, so if that's what you program, I recommend you to try.
Second, the VDF community is tightly knit and we will publish free code and add-ons, questions answered immediately and with great skill on the newsgroups, and you will be among an elite membership, where a close relationship with developers is very attractive.
Visual DataFlex is antransparent front-end for virtually any database back end on it, such as MS-SQL, IBM DB2 use, etc.
If you are afraid of being fired for using a non-Microsoft product, please ignore this item complete!
* Who makes Visual DataFlex?
The answer is surprising. Of course makes Data Access Worldwide of Miami FL USA, the product, but it is mainly through suggestions of every contributor, the personal feedback received from the company createdRepresentatives on our newsgroup forum and feedback to meetings in person. Imagine that you can see the direction that are the product flows and your actual bug reports form included with the corrections in the next version! Honor to whom honor due.Data Access also has distributors worldwide and is a global product established in many countries.
* What kind of support I would get to newsgroups or support groups?
Example: If you are from New England, USA, you can join the NEDCUser Group, the developers are welcomed and has regular meetings in person in order to promote camaraderie and show tech presentations on current projects members.In Visual DataFlex There is also a newsgroup that a degree will be monitored by Data Access Technical Support , but this feedback is mainly based Visual DataFlex developers globally and I personally recommend these news group for the high quality of support received (and given) over the years.
* What isthe future of Visual DataFlex?
Data Access Corp. network partner has many locations, the introduction of the latest available features such as ActiveX, Web Services, etc., and is in the process, version 12.1, which is very familiar to you at the start. NET developers. In addition, the free Personal Edition ~ ~, the entire studio and connectivity kit contains all 5 user limit at the last meeting convened global "Synergy" in Miami Beach FL in 2007 was unveiled. The promotion ofThis product is largely word of mouth and keeps the tradition and the nickname of the product as a ~ The best kept secret in database programming are alive ~!
I invite you to pop open a search engine and search for Visual DataFlex to see what all (not (vertebrae)) is about!
Peter was the development of custom database applications since 1982 and has hiked its development techniques by DOS / Windows / Web programming, and oops specialization by key encryption in bothWindow / Web Reporting, and Crystal. An authorized technical service center VDF teacher for 10 years, Peter extinsively over 3 continents and visited training codeveloping with IT staff.
