Language Specifications
-----------------------
DAL is a complete language for describing connectivity tasks. It consists of these statement groups:
- Host Connection Statements
These establish and terminate a connection to a host system in the network. This provides concurrent access to multiple hosts running DAL Servers.
- Data Manipulation Statements
These offer complete ANSI standard level 1, SQL-based data access to host databases.
- Program Structure Statements
These support testing, looping, and procedure calls within a DAL program.
- Output Statements
These generate output messages from the DAL program. The client application software processes these messages.
System Requirements
-------------------
To use the DAL Server for A/UX, you need the following hardware and software:
- Host environment: A/UX version 2.0 or later. We recommend the A/UX CD-ROM product or the A/UX floppy product. We don't recommend the A/UX external 80MB hard disk because it doesn't contain the software you need to repartition the disk for the DAL Server for A/UX.
- One of the supported database management systems
- Macintosh computer clients running DAL-compatible application programs.
- The appropriate networking hardware and software
