Caché Object Database

Caché, the post-relational object database from InterSystems, has the features professional developers need to quickly create Web and client/server database applications. Caché object database benefits developers by giving them their choice of development tools, programming languages, and methods of database access. Caché object database benefits transaction processing applications by providing outstanding performance, massive scalability, real-time data analytics, and robust reliability.

All these capabilities are tied together in an easy-to-use rapid development environment. With Caché object database, ALCADE makes applications faster.

Using Intersystems Caché Object Database

One of the greatest challenges facing e-developers is the inherently stateless nature of the Web. Usually, once a server sends a page, it forgets all about it, which can make completing transactions difficult. Web application developers spend most of their effort making it appear as though a series of independent "page hits" is a single session between browser, Web server, and database. But Caché object database encapsulates all that system-level programming into Caché object database session objects, thereby making session management much easier. Session management objects work with both HTTP, and (for secure transactions) HTTPS. In addition, for more complicated transactions, or those that require multi-page database locks, Caché object database allows the use of dedicated session processes.

Caché object database Server pages consist of standard HTML or XML, so they can be created and modified using any text editor or off-the-shelf Web page creation tool. Object database applications can be designed as though they were a series of static Web pages. Navigation through these pages is handled automatically by Caché. Functionality (the working part of any Web application) is added by incorporating Caché object database Applications Tags or Hyper-Events™.

Caché object database Application Tags (CATs) work like HTML tags, except instead of formatting text, they execute functions on the data servers and/or browsers. CATs may be used to perform a variety of functions, such as:

• Fetch data to populate fields in forms.
• Validate information entered into forms by users.
• Transform coded or calculated items.
• Save data back to the Caché database.
• Control the HTML written to the browser, for example, by creating loops to generate rows in a table dynamically, or by creating conditions that include or exclude parts of the page.
• CATs are extensible, so developers can create tags to fit the needs of specific applications. Once created, Web designers can use CATs to add functionality to their pages, without worrying about the processing details.

Caché object database Server Pages may also include Hyper-Events™ that enable browser events (clicks, mouse movements, timeouts, etc.) to trigger object database actions without waiting for an entire page to be submitted. This allows Web object database applications to be much more interactive and responsive to users.

One key element of Caché's object database outstanding performance and scalability is its multidimensional data server, optimized for transaction processing.

"Multidimensional" means that data can be indexed by as many parameters as needed - it is not constrained to fit into rows and columns. This allows for much richer data models than can be achieved using relational technology. Complex data can be stored and used in a much more natural way.

Relational databases have a difficult time representing complex data because they break up information so that it fits into flat, two-dimensional tables. When relational technology is used to describe real-world data, tables pile upon tables and sub-tables, and a great deal of processing is required to "reassemble" the information needed to complete transactions.

Multidimensional data does not have to be "reassembled" from its component parts. The Caché object database multidimensional data server eliminates the processing overhead associated with relational technology, resulting in a significant boost in transactional application speed.
