Info

www.progress.com The significant advantage of the first point is that the application no longer has to manage tenancy—simplifying the code and making tenancy completely transparent. For the second point, the operational aspects of the database are also capable of acting in a mode that is either tenant-specific or database-specific. This streamlines key functions such as index maintenance, data dump and load, object moves, and other database functions. DATABASE MULTI-TENANCY 1. Multi-tenant Database Tables A key addition to the OpenEdge database is built-in support for multiple tenants within a single database. Many database vendors are promoting multi-tenancy as a new capability for SaaS and Cloud. But with OpenEdge, the unique difference is that instead of the client managing access to tenant data, the database takes care of everything. This means that minimal changes are required for application code; in fact, tenants run the exact same r-code, and utilize the exact same schema definition, as users of a non-multi-tenant instance of the same application! Furthermore, each tenant’s data is stored in database partitions that are physically separate from those of other tenants, enhancing data access and making database maintenance easier and more efficient. 2. Web-based Multi-tenant Tooling as an extension of OpenEdge Explorer and OpenEdge Management OpenEdge 11 includes the Web-based Database Administration Console as an extension of OpenEdge Explorer and OpenEdge Management. This new interface for managing tenants—including tenant users, tenant storage, and tenant security—features a brand new look and feel. A template-based approach provides for increased productivity, and the tool can also generate ABL code that developers can re-purpose in scripts or ABL applications. 3. ABL APIs for multi-tenancy An extensive set of ABL APIs for multi-tenancy allows application developers to integrate tenant management into their own applications, for example to provide the capability for tenants to provision themselves, or to build multi-tenant management tools that are more customized to your development and deployment needs. 4
4. SQL DDL support for multi-tenancy www.progress.com SQL has been enhanced to multi-tenancy, allowing application tenants to enjoy equivalent functionality with both ABL and SQL. *New database multi-tenancy functionality for OpenEdge 11.1 includes: 5. Multi-tenant Governor for users per tenant With OpenEdge 11.1, it is possible to limit the number of users (-n) that an individual tenant is able to connect to a multi-tenant database. 6. Multi-tenant Governor for record locks per tenant This governor, available starting in OpenEdge 11.1, limits the number of record locks (-L) available to a particular tenant at one time. 7. Enhanced multi-tenant tooling in the OpenEdge Explorer Data Administration Console OpenEdge 11.1 introduces several new capabilities to OpenEdge Explorer’s Data Administration Console, making it easier to manage tenants. Included are the ability to rename tenants, tenant groups, and/or tenant domains; the ability to dump and load tenant data; and an improved user interface for filtering and batching large datasets. Tenant partition management is also made much easier with the addition of drag-and-drop support. In addition, OpenEdge Explorer includes the ability to manage the new multi-tenant governors. 8. SQL support for Tenant Groups OpenEdge 11.1 includes functionality that enables SQL to work with tenant groups in terms of data definition, data management, and data access. 9. Super-tenant SQL access to LOB data Starting with OpenEdge 11.1, the super-tenant is able to access tenant LOB data. PRODUCTIVITY OpenEdge 11 continues to focus on improving productivity so you can spend more time working in ways that will add value to your business.
