ASTA Web Service Tools             Since 1998 ASTA Web Services have been used by developers in over 70 countries to create thin client windows client applications that can run over the Internet. ASTA’s mature Application servers are known for their easy deployment, scalability and robustness.  ASTA uses the N Tier architecture as described in the following diagram:                   In the spring of 1999 ASTA released the first Java messaging class and launched the ASTA Unified Messaging Initiative (UMI). The goal of UMI is to provide cross platform messaging on all platforms. In the year 2000, ASTA extended UMI to support handheld devices such as the Palm, Wince and Linux PDA’s and in Q3 2000 released Code Warrior C++ Classes for the Palm OS and eVC++ Classes for the Wince. These C++ Classes allow for Palm and Wince devices to use ASTA Messaging to communicate with remote ASTA Application servers.                ASTA has always provided support for online as well as offline users. One of the great limitations of browser technology is that it is only available when you are connected to the Internet. The ASTA architecture was designed to support Online and Offline users and to be able to synchronize and merge information created in either state. This feature is particularly important for remote handheld clients, as they were not designed to stay connected to remote servers but depend on “Synchronization” techniques to merge and fetch data from desktop or remote sources. ASTA Windows Clients have always had the ability to use “Cached” updates built on top of a row/column abstraction known as the TDataSet. ASTA is committed to implementing the features it has had since 1997 for Windows Clients to all platforms and for all popular development tools.   ASTA Cross Platform Feature Set   Asta ParamList Messaging Available ASTA Handheld Database API Available Compression Available April 2001 Encryption Available April 2001 XML Available Q2 2001 TAstaPDADataSet Available Q2 2001 TAstaPDAGrid Available Q2 2001 Graphing tools Available Q2 2001 Dataaware controls Available Q2 2001 Http support Available Q2 2001     ASTA Clients 32 bit windows NT, Windows 2000, Win9X Delphi, C++ Builder Available   Visual Basic, VC++ any development tool that can support COM Q2 2001   ODBC Driver Q2 2001 Java JDBC Driver Available Palm Code Warrior C++ Available   CASL Available   Pocket Studio's Pascal Upon Release   NS BASIC Q1 2001   App Forge Q2 2001   Falch C++ Q2 2001   Scout Builder In Development   Satellite Forms In Development Wince Embedded VC++ Available   Embedded VB Q2 2001   CASL In Development   NS BASIC In Development Linux PDAS gcc compilers In Development Symbian EPOC Visual C++, Code warrior C++ In Development ASTA Windows Servers AstaADOServer via ADO Access, MS SQL Server, Oracle AstaODBCServer via ODBC Access, MS SQL Server, Oracle, Informix AstaOracleServer Native Access to Oracle AstaBDEServer- Borland Database Engine XBase,Paradox, Oracle, Sybase, Informix, DB2 AstaMySQLServer Native Access to MySQL AstaInterBaseServer Native Access to Interbase AstaCTLibServer Native Access to Sybase and Adaptive Server anywhere AstaASAServer Native Access to AdaptiveServer Anywhere AstaHandHeldServer Royalty Free Database Engine using Dbisam  ASTA Servers for Cross Platform Support Operating System Availability NT, Windows 2000, Win9X Available via Delphi and C++ Builder NT, Windows 2000, Win9X Visual Basic, VC++ any development tool that supports COM Q2 2001 Linux Release Date Q2 2001 via Kylix Java Release Date Q2 2001 any Java development tool   If additional information is needed, please contact us at info@astatech.com.  Thank You!
