- OVERVIEW
-
- Paradox SQL Link is an add-in product that allows you to use
- Paradox 3.5 as a front end for accessing data from a SQL database
- server. You can use Paradox's interactive menus or the PAL
- language for accessing this information, without having to learn
- SQL programming.
-
- SQL (Structured Query Language) is an internationally established
- database language for managing relational data. To use the data
- the SQL language statements must be used. Paradox SQL Link
- operates as a layer between Paradox 3.5 and the SQL server,
- translating a Paradox operations into the appropriate SQL
- commands and then forwarding them to the server. The commands
- are then executed and any result is returned to Paradox as a
- normal answer table. Paradox can simultaneously work with remote
- tables and conventional paradox tables.
-
- SQL is usually implemented in a client-server architecture.
- There is a database server (commonly a mainframe, mini or high-
- end PC.) with clients (generally PC's) connected through a
- network. Paradox is run on the PC workstations of the network.
- Since the data is stored and directly manipulated on the central
- server, having a powerful server machine can yield good
- performance without high machine requirements for the client
- workstations (80286 or higher CPU, RAM requirements below).
- Using Paradox as the front end, allows access to larger amounts
- of data without learning a new software package. Data security
- and maintenance can also be simplified by having the data stored
- on one central machine.
-
- The SQL servers currently supported are: RAM Req'd:
- (megabytes)
- DEC VAX Rdb/VMS 3.1B 1.0
- IBM Extended Edition Database Manager 1.2 or higher 1.0
- Microsoft SQL Server 1.x 1.0
- Oracle Server 6.0 or higher 1.5
- Sybase SQL Server 4.x 1.0

-
- ABILITIES
-
- Some of the capabilities of Paradox 3.5 with SQL Link are:
-
- 1)Queries on database tables
- a)for manipulating data on the server or
- b)retrieving data from the server.
-
- 2)Table creation and access of existing tables.
-
- 3)Table manipulation (add, copy, delete, empty, etc.).
-
- 4)Reporting of information existing on the server.
-
- 5)Added PAL commands and functions for programming access to the
- server.
-
- 6)Application of transaction processing techniques for data
- integrity.
-
- REQUIREMENTS
-
- The database server and appropriate network must be running. The
- workstations must be running Paradox 3.5 in protected mode to
- utilize SQL Link. (See your User's Guide, Chapter 14 - Advanced
- Topics/"How Paradox manages memory" for additional information on
- protected mode.)
