Fortress, Xbase Server for:
To make Fortress Xbase Server (tm)the best Client/Server solution for Xbase applications, we pulled out all the stops o Incorporated our award winning Comix Database Engine for high speed indexing and data access. o Developed advanced locking techniques for fast and reliable concurrent access. o Incorporated Transaction Processing to protect the integrity of your database and indexes. o Designed procedures to greatly reduce network traffic. o Plugged in state-of-the-art Bit Map Query Optimization
with two levels of functionality. Fortress Xbase Server delivers Client/Server performance
and reliability without retraining and without the high prices. Faster is Better Greater and greater demands are being placed on your
applications and your hardware. You can use Fortress Xbase Server and get outstanding
performance and reliability without turning your world upside
down. Why is Client/Server so much faster? Reduction in network traffic is one of the key reasons that Client/Server is so much faster than typical File Server systems. Through centralized control of the database only the
records that are actually needed are sent over the wire-network traffic is greatly reduced and your applications run much faster. Why is Fortress Xbase Server so much faster? We didn't stop at just reducing network traffic- that was
the easy part: o High Speed Database Engine: We took our award winning Comix RDD-proven performance and reliability-and fully integrated the speed and functionality into Fortress Xbase Server o Smaller Is Faster: Fortress Xbase Server uses FoxPro CDX indexes which provide significant performance advantages: multiple indexes are in a single file-reducing the file server handle load; CDX's are 3 to 6 times smaller than NTX's and make efficient use of memory and disk space. o Proprietary Caching Algorithms give you the advantage of single-user caching in a multi-user system. Many operations are performed with zero network requests. That's right-absolutely no network traffic! Much of the overhead associated with indexes and databases is eliminated. o Advanced Locking Techniques protect database and index integrity while greatly reducing the number of conflicts and performance hits inherent to multi-user access. o Bit Map Query Optimization: Fortress Xbase Server's bit map query optimization provides performance advantages which are simply not possible in Xbase alone-10 to 1000 times faster. Fortress Xbase Server's query optimization gives you the advantages of SQL access (fast and easy selection of a set of records and greatly reduced network traffic) in an easy to use SET FILTER TO Interface. By setting our standards for performance higher than simply
reducing network traffic, Fortress Xbase Server provides the best performance possible. You'll have to try it to believe it! Reliability As businesses become more dependent on computers downtime and system glitches become ever more costly. Through centralized control of the database, Fortress Xbase Server greatly improves the reliability of your applications. Consider for example the typical PC network. Each user who has update access to the database has the potential to corrupt it, by the simple action of shutting off the machine or rebooting at the wrong time. The statistics are particularly grim. If there's only a 1 in 1000 chance that a user will shutdown improperly on any given day (this is very generous for some installations), a 100 user system
has a 10% chance of failure on a given day-the more
users, the worse it gets. With Fortress Xbase Server the update of both the record and
indexes is an atomatic operation-either the server gets the updated record, or it doesn't. If it does get the updated record, it guarantees that all
indexes are also updated. If it doesn't get the updated
record, then it's as if the update had never occurred;
thus the integrity of the system remains intact. Ease of Use With Fortress Xbase Server moving your applications to Client/Server can be as easy as relinking. Indexing commands and functions are automatically mapped to the corresponding Fortress command or function. Additionally Fortress is 100% API
compatible with Comix and ClipMore. Fortress Xbase Server's rich feature set provides
powerful-yet simple-solutions to many of the problems you face in application design
and implementation. Custom Built Indexes let you
"customize" an index by adding or deleting keys-you've got total control and
anything goes! Scoped Indexes act like an instant sub-index. Use SET SCOPE
TO and instantly restrict the view of the database to records in a certain range (records
with age = 25 for example.). SET RELATION TO ... SCOPED dynamically sets a scope on the
child database. When you select the child workarea, only the records related to the current parent record are visible. Handle true one to many
relationships with ease in one line of code! Conditional Indexes: INDEX FOR allows you to include keys
for only certain records. INDEX WHILE or USECURRENT lets you rapidly create new indexes, using the information in existing indexes. Virtual Unique Indexes: Make a non-UNIQUE index "look
like" a unique index instantly-eliminate the
overhead and performance hits of unique indexes by
using ftSkipUnique(). Enforcement of Unique Keys: Fortress Xbase Server allows
you to specify UNIQUE as an attribute of indexes that you create. The system ensures
that each key in the index is unique. Reversible Indexes: With Fortress there's no need to have
two separate indexes-one descending and one ascending. Reversing the order of the index is as easy as SET DESCENDING ON. Binary Memo Fields: Fortress allows you to store binary
data directly in memo fields for unlimited flexibility. Blow past DBT limits! Automatic Transaction Tracking for single record updates
and deletes ensures the integrity of your data and indexes. Should a client go down mid transaction, the changes aren't commited. System integrity
automatically remains intact! KeyNo() and KeyCount() work like recNo() and recCount() to
let you easily provide modern interfaces with scroll bars and "record n/total"
displays in index order. SEEK ... LAST: Find the last occurrence of a key as quickly
and easily as you find the first! Undo Changes: Effortlessly roll back the changes made to a
record using ftUndo()! Eliminate complex scatter/gather routines and memvars; directly edit fields instead. Breakthrough Technology One thing that's easy to do with SQL? Get a set of records.
In fact that's the only way SQL gives you access to
records-by sets. Even if you only need one record! Fortress Xbase Server gives you the best of both worlds:
the familiar SEEK and other Xbase commands for record oriented access; advanced bit
(tm)ap query optimization for quickly accessing sets of
records. Bit Map Query Optimization is a powerful technique that
rapidly finds records meeting a general condition by using indexes instead of scanning the actual database. The difference in performance is as
significant as a SEEK (uses an index) versus a LOCATE (reads the records). With Fortress's query optimization, performance gains of up to 1000
times faster are not uncommon. Add blazing speed to ad-hoc queries, reports, TBrowse's,
replaces, and anywhere you do selective data
access-it's as easy as SET FILTER TO! SET FITER TO Interface: Though simple and powerful, SET
FILTER TO is often considered a "beginner's command": it is seldom used by
seasoned developers due to poor performance. Fortress's
automatic query optimization blows away the performance issue. Replace your complex
hand optimization code with one simple line-SET FILTER TO. Fortress's easy SET FILTER TO Interface makes it easier for
you to design applications by allowing you to focus on what you want to do rather than how to do it. Low Level Bi (tm)ap Control: The SET FILTER TO Interface
makes query optimization a breeze and easily handles
the majority of optimization tasks with ease. However,
when we first introduced our query optimization technology in ClipMore, we quickly found
that many seasoned programmers wanted more! For the ultimate flexibility, Fortress Xbase Server gives you access to the low level bit map control functions-the recordlist functions. These are the same functions used to implement the easy SET
FILTER TO interface. Maximize ROI You've got a lot of time invested in existing applications,
your knowledgebase, and hardware- Fortress Xbase Server
eliminates the need for costly SQL training and extensive reprogramming. Fortress Xbase Server supports CA-Clipper 5.2 and is
compatible with your favorite third party libraries and tools such as Blinker 4.x, FiveWin, and Clip4Win. The server cost is better than anything on the market; the
training cost is nil-you already know how to use it;
re-development time is based on the level of extended
functionality you want to incorporate. As an Xbase solution to the Client/Server problem, Fortress
Xbase Server gives you the maximum return on investment (ROI). You can move your existing applications to Client/Server without extensive
reprogramming or downtime-in no time at all. Fortress Xbase Server Fortress Xbase Server runs as an NLM or on a dedicated
