Reviewing Data Access Conceptual Architectures
This section provides a conceptual overview ofKey Architectural Components & Relationships
OpenLink's Universal Data Access products all share the same, basic architecture.






Basic OpenLink UDA Architectural Requirements
Applications must be ...
- ODBC, JDBC, OLE DB and/or ADO .NET compliant
- SQL compliant
- Hosted on a platform for which
OpenLink produces UDA client products
- Speak the same data access API as the UDA client product
OpenLink client products must be ...
- Installed on a supported platform
- Installed on the same machine as the client application
- Paired with same version
OpenLink server components when applicable
- The same bit format (32bit, 64bit) as the client application
- The same bit format as any other architectural component (i.e., driver manager) on the client machine
Important: |
OpenLink server products must be ...
- Installed on a supported platform
- The same bit format as any other architectural component (i.e., DBMS, DBMS native client) on the client machine
- Paired with same version
OpenLink client components
Important: |
Data repositories must be ...
- SQL compliant
- Some version supported by
OpenLink
TCP/IP Networking must be ...
- Enabled among machines comprised by the architecture
- Permit relevant machines to communicate through firewalls, where applicable
OpenLink UDA Architectural Assumptions
OpenLink assumes that potential users:
- Want to query, migrate, or integrate SQL data using some combination of ODBC, JDBC, OLE DB, and/or ADO .NET compliant applications.
- Already possess the requisite applications and data repositories.
- Already possess 3rd-party JDBC or ODBC data sources when bridge connectivity is required.
Decisions Affecting OpenLink Architectural Planning
Architects need to determine ...
- The prioritization of performance, price, and security.
- Which machines can host
OpenLink Data Access components.
- How the data access layer will be secured.
- What non-
OpenLink data access architectural components exist in the architecture or can be easily obtained.
Issues Associated With Use of OpenLink Architectures
- Applications or data repositories may be hosted on platforms that
OpenLink does not support.
-
OpenLink may not have products that support connectivity to legacy data repositories.
- All architectural components hosted on a client machine must share the same bit descriptor, e.g., 32 or 64 bit. All architectural components hosted on a server machine must share the same bit descriptor. The same is true for components hosted on a gateway machine.
