Electronic Parts Libraries with Failure Rates - IsoLib from Isograph

IsoLib Server

What does the IsoLib Server do?

The IsoLib Server program is used to create and maintain the database for the IsoLib Parts Libraries program.

The database can be created in either an existing SQL Server installation or in a Microsoft SQL Server Desktop Engine (MSDE) instance created using the IsoLib Server installation program.

The IsoLib Server program allows the system administrator to perform the following functions:

  • Add and delete SQL server logins and Windows logins as SQL server users.
  • Add and delete SQL server users as database users and add and delete them from the IsoLib Server pre-defined database roles.
  • Change the password for SQL server logins.
  • Add and delete parts libraries from the IsoLib Server database.

IsoLib Server Authentication

The IsoLib Server program and database supports both SQL server logins and Windows authentication. Normally, Windows authentication is used as this allows users to access the database using their Windows login without entering any further information.

SQL server logins are normally used when accessing the database over the Internet and require entry of the username and password when accessing the program. Regardless of type, logins are associated with one of three pre-defined database roles:

  • is_admin role which is used for users who will add and delete parts from the database.
  • is_user role which is used for normal users.
  • SysAdmin role which has full control over the database, including administering users.

(NB: After installation the IsoLib Server database contains no part information. Isograph supply part libraries as .isl part files and these are explicitly added to the database by a member of the is_admin or SysAdmin roles after purchase of the corresponding IsoLib Parts license(s). )
