Designing databasesThe first step in creating a relational database is to construct a data model, which is a precise, complete definition of the data you want to store. After you prepare your data model, you must implement it as a database and tables. To implement your data model, you first select a data type for each column and then you create a database and tables and populate the tables with data. You can also implement fragmentation strategies and control access to your data.
Designing and Implementing a DatabaseThe HCL OneDB™ Database Design and Implementation Guide provides information to help you design, implement, and manage your HCL® OneDB® databases. It includes data models that illustrate different approaches to database design and shows you how to use structured query language (SQL) to implement and manage your databases.

Table permissions

Permissions for accessing table in other databases and remote tables are controlled at the table location. When accessing a remote server, the connection is made using the login name and password of the user executing the query. To access remote data, the user must have the correct permissions on the remote table.

When processing distributed queries, the database server ignores the active role on the current local database when accessing a remote object. On the remote server, the default role applied to each remote database is used. If a default role is not defined, the user's privilege define the access permissions for the objects in each remote database.
