ISAM
The Arbutus technology provides direct access to ISAM data for use
in a variety of applications. Arbutus provides the LegacyLink™ middleware
that connects your Windows applications directly with your ISAM and other data. As well,
Arbutus offers query, migration and data warehouse prototyping solutions.
Our technology is unique because of its ability to not only access
ISAM, but to join it with disparate data from
IMS, DB2, QSAM,
VSAM and other ISAM files with
no additional infrastructure. Users can benefit from one
view of the requested data, even when multiple
sources are involved.
In fact, the Arbutus technology allows virtually any file, regardless of
complexity, to be accessed and combined in any manner as if they were part of a database or data warehouse. As a result,
using our LegacyLink™ middleware, any SQL query can be executed directly against the source data.
Key features:
- Supports SQL queries directly against ISAM
data using our LegacyLink™ middleware
- Combines your ISAM data with DB2, IMS, VSAM, QSAM
and
AS/400 based data
- Allows ISAM files to be automatically defined
using existing COBOL or PL/1 record definitions
- Ensures security/integrity by providing read-only access
to the data
- Displays only those ISAM files and columns chosen to
be accessible by the administrator
- Allows data definitions to be easily modified at any
time
- Allows table and column names that the user sees to
be easily modified for readability or usability
- Supports the creation of dynamic "virtual" columns
based on the contents of the data without requiring any
changes to the ISAM file itself, by utilizing over 80
built in functions
- Enables ISAM files to be joined with any tables,
either via SQL or star schema relationships
