Project Source

A Project Source is an alias in which connectivity

information for all the projects in that Project Source is

stored.

2Tier

Project Source Specifies a DSN

and login for a direct connection

to metadata.

3TierProject Source identifies the

MSTR I-Server machine to

which the client will connect.


3/21

Project Source (continued)

A Project Source (PS) houses the information needed to

connect to a Metadata at start-up

A PS can contain several projects, each of which can

potentially connect to a different DW. However, therecan be only one metadata per PS, so all projects within

a PS share the same metadata

PS can be created in either 2-tier (direct connection to

the metadata) or in 3-tier (through Intelligence Server)

mode.

Well have both modes of connection for different

phases of the projects in the class.

2 - Tier

5/21


2 Tier (Direct):

A local ODBC DSN must be

specified along with the

login.

This information is stored inthe registry of the local

MSTR Desktop machine.

ODBC PWD is stored

encrypted in the registry of

the local machine.


6/21


3 Tier (Intelligence Server):

No ODBC connection from

the client to the DB

MSTR Desktop client will

connect to I-Serverdefinition, so the name of I-

Server and RPC connection

to it are necessary.

All connection information

and MD DSN are located onthe Server machine.


7/21

Database Instance

A Database Instance is a logical representation of a

connection to a physical database.


8/21

Database Instance

Each PS is associated with one MD DB Instance and at least one

Warehouse DB Instance.

Database Instance stores the following information:

Database Connection

Type of DB (Oracle, SQL Server, Informix, etc.) Maximum number of connections allowed for the DB Instance

DB specific optimizations (I.e. VLDB properties)

Warehouse table prefixes (if required)

Location for intermediate table storage

Prioritization scheme to be used when submitting jobs to the DB


9/21

Database Connection

A Database Connection is

comprised of a DSN and

other information necessary

for connection to a

database. Each Database Instance can

potentially point to multiple

Database Connections.


10/21

DSN and Database Login

The DSNs listed represent

the local machines system

ODBC data sources and

DSNs from other sources.

A Database Login stores theUID and PWD that will be

used to access the database

or the NT network login


11/21

DSN and Database Login

DSNs listed will list local machine DSNs and all

other DSNs recorded in Metadata.

In a 3 tier environment, DSN may or may notactually be a DSN on a local machine.

Theres unlimited number of Database Logins that

can be created, this functionality is needed for

advanced administration and monitoring by DBAsand thus wont be discussed in this class.

Goals:

Create VMALL Warehouse Instance

Prerequisites:

Completion of Database Connectivityworkshop


15/21

Workshop1. Open MicroStrategy Desktop

2. Go to ToolsProject Source Manager3. Click Add


16/21


17/21

Workshop6. Now connect to your Project Source, your default login is

Administrator, the password is blank.7. Now well create Database Instance for our Data Warehouse

8. Go to AdministrationDatabase Instance ManagerRightClick select NewDatabase Instance


18/21

Workshop9. Name your DB Instance VMALL Warehouse, choose your

database type (SQL Server 7.0) and create a new DBConnection:


19/21

Workshop10. Select your Warehouse DSN in the list of all DSNs, choose

Administrator as your default login.11. Click OK twice, your Warehouse connection is created!


20/21

Next steps

Well go over Data Modeling and create ourproject!
