TM1 Programming Concepts

There are a number of issues that every TM1 programmer encounters when using the TM1 API.
This post describes some of those issues. The following topics are discussed:

• System Functions - Every TM1 program must use the TM1 system functions to communicate with the TM1 server, and manage its connection during program execution. This section describes those functions.
• Simple TM1 Data Types - Description of the types of values supported by the TM1 API.
• Values - Most TM1 functions use values to store and manage information. This section describes the types of values used by the TM1 API, and how those values are manipulated.
• Security - The security of your data is of paramount importance. This section introduces two TM1 objects dedicated solely to security: Clients and Groups.
• Backup and Recovery - The TM1 server offers functions that allow full recovery of all cubes in the event the TM1 server is not properly brought down. This section describes the functions that allow you to recover your data in the event of a crash.

This chapter also includes:

• Creating a TM1 Project in C or C++
• Creating a TM1 Project in Visual Basic

System Functions:

The system functions control the connections between the TM1 client application and the API, and between the TM1 API and the servers. This section describes those functions.

Connecting to the API:

The following sections describe the function call sequence for:

• Connecting to the TM1 API in C
• Connecting to the TM1 API in Visual Basic
