- The P-Kit is the first persistence library providing a complete,
- powerful and simple interface between Object-Oriented Languages and
- Object-Oriented Database Management Systems. The P-Kit provides a
- unique tool to aid the developer in designing persistent mission
- critical custom applications.
-
- Because the P-Kit removes virtually all programming overhead in storing
- and retrieving objects, persistent mission-critical applications are
- developed rapidly, all the time allowing for accurate modelling.
-
- The P-Kit addresses the following issues:
-
- Transparency:
-
- Unlike using other database interfaces, there is no requirement to
- generate and maintain specialized persistent versions of classes.
- Persistence can be added to third-party libraries and existing programs
- with minimal adjustments for fine-grained control.
-
- Portability:
-
- By encapsulating the persistent storage medium, developers working with
- Objective-C or Eiffel, and the P-Kit are freed from implementing
- low-level persistence related solutions and do not need to address
- different database interface languages. By using the P-Kit, persistence
- programming becomes uniform across heterogeneous databases.
-
- Extensibility:
-
- Users of the P-Kit can easily extend or re-write actions such as those
- for storing and retrieving objects.
-
- Anonymous Objects:
-
- The P-Kit provides a powerful mechanism through Anonymous Objects,
- allowing manipulation of database objects without the need to have their
- class defined in your application.

- Hutchison Avenue Software has been providing object-oriented software
- consulting services to Wall Street financial companies for three years.
- During this time, Hutchison has developed several innovative solutions in
- collaboration with their clients, one of which is WSC Investment Services,
- a firm providing technical services to the brokerage industry.
-
- The idea of the P-Kit arose out of software design meetings between
- Hutchison Avenue Software and WSC Investment Services. Paul Murphy,
- WSC's Director of Advanced Technology was part of the planning and
- design for the original Eiffel P-Kit:
-
- "When we first started looking at our systems' requirements, we realized
- we were going to need the performance and characteristics of an object
- database. We also realized that tying ourselves to a single vendor was
- foolish given the state of the market. We needed high-performance,
- flexibility, and isolation from the database's API. All in all, a tall
- order. We approached Hutchison because of their expertise in this area.
- Having worked with them in the past, we had complete faith in their
- technical staff. The current version of the kit surpasses our original
- expectations," says Murphy.
-
- The P-Kit currently supports O2 Technology's O2 database. A Flat-File
- adaptor is also available allowing the P-Kit to make objects persistent
- without using a database. Adaptors for other databases are currently in
- the works.
-
- Documentation for the P-Kit is available both in Postscript and RTF
- format at: ftp://hasc.ca/pub/pkit
