What new features does Caché deliver for MultiValue developers?
At the heart of Caché is a powerful, multidimensional transaction engine that includes the ability to easily deploy distributed databases. This provides application developers with a unified data architecture uniting the power of objects, high performance SQL and traditional MultiValue data access.
For MultiValue applications, Caché offers:
A complete native object model in MVBasic, including object inheritance, persistence and polymorphism
Native, object-based XML and Web Services support
MultiValue aware Studio integrated development environment
Caché Server Pages (CSP) using MVBasic
Blindingly fast SQL (concurrently with MultiValue queries)
Complete security model (including auditing and encryption of data-at-rest)
Simple, web-based system management
On what platforms does Caché run? Is MultiValue functionality supported on all Caché platforms?
MultiValue features are a standard part of Caché, and are available on all Caché platforms.
High-performance database technology has been the cornerstone of InterSystems products since our founding 28 years ago. For object and SQL based applications, Caché is the engine of choice for both performance and scalability. Our continuing investments in the Caché engine will bring new levels of performance for MultiValue applications.
Will I have to abandon my MVBasic development environment?
No. Caché fully supports MultiValue Basic (MVBasic)
. You can continue to develop applications using MVBasic and MultiValue Queries. The new features are available to re-use and extend your application logic via Java, EJB, JDBC, ActiveX, .NET, C++, ODBC, XML, SOAP and more.
Once I migrate my MultiValue application to Caché, can I use all the other Caché features (objects, SQL, dynamic Web pages, Web Service, etc.) to access my MultiValue data?
Yes. Caché’s Unified Data Architecture means that you can access your data as objects, SQL, as MultiValue files or using MultiValue queries.
Does Caché support a query language like English, Access or Recall?
Yes, we do and it is very similar to that on other MultiValue systems. English is the Microdata name for it; Access is the PICK name; Recall is the UniVerse name.
How do I move my code and my data to Caché?
Caché provides a utility, MVIMPORT, to import files that have been created with account export utilities from MultiValue products.
