Some useful features of ADS:
| provides flexibility of data access
 | WinGAP data tables remain in their native Fox2x format |
| ADS has native access to fox tables (via RDD), no additional data access
engine required (e.g. ole db, ado, odbc) |
| native access means better performance |
| native access mean no translation required for WinGAP |
|
| high performance database engine
| uses optimized client/server architecture to increase multi-user
performance, database stability, and database security |
| network traffic and concurrency are formidable problems for
non-client/server multi-user database applications that cause large amounts
of network traffic because client machine performs all database processing,
ADS performance improvements are achieved primarily by reducing network
traffic, by intelligently maintaining database files, and by providing
intelligent lock management |
| Client Server
 | true client/server technology involves an intelligent division of
processing between the client and the server |
| ADS optimizes your network resources and performance by performing
database application operations where they most make sense |
|
| High-speed locking
| ADS uses an intelligent lock management system that eliminates lock
retires and network traffic |
| write lock queuing and elimination of lock retries greatly increases
multi-user database application performance. |
|
| Decreased Network Traffic
| uses client/server architecture to off-load all index traffic
associated with index look-ups and index maintenance |
| allows a central point of control for all database operations |
| no index data is ever transferred across the network to the client
workstation |
| all database opens, reads, and writes are performed on the server by
ADS where the data exists |
| since ADS performs all data processing on the server, the CPU on the
server is fully utilized. ADS has both the workstation CPU and server CPU
working for maximum performance |
|
|
| Client / Server
| ADS keeps operations where they make the most sense:
| User interface and most business rule processing is performed on the
client |
| Database access and updates are performed on the server where data is
located |
|
|
| Security
| ADS runs on server as Administrator |
| Other software is granted read-only access to table opened by ADS (VFP,
Excel, Access, etc) |
|
| Scalable
| Local Server |
| Peer-to-Peer |
| Client / Server |
| User licenses include: 2, 5, 10, 25, 50, 100, 250, unlimited (limited
only by RAM) |
|
| Cost Effective
| Unlike nearly every other DBMS, ADS does not require a DBA on staff. |
|
| Easy to Install / Setup
| Install ADS on Server: 10 mintues |
| WinGAP link to ADS
| edit ADS.INI: ADS_SERVER_TYPE=2 |
| edit WINGAP.INI: RDD=AXDBFCDX |
|
|
| Data Integrity
| all read/write instructions performed on server eliminates data and
index corruption |
| transaction based processing completes each 'instruction' to finality or
rolls back if interrupted |
