As per definition, MSBI or Microsoft Business Intelligence is a powerful suite of tools that provide solutions for Business Intelligence and Data Mining queries. MSBI empowers users to gain access to accurate and up-to-date information for better decision-making in an organizational level. There are three tools that constitute the bulk of MSBI:

SQL Server Integration Services is a component of SQL Server in MSBI. This tool can be used to perform numerous data migration and ETL operations.
This platform is used for integration and workflow applications. Known for its quick and flexible OLTP and OLAP extensions for data extraction, transformation, and loading (ETL), SSIS can also be used to automate the maintenance of SQL Server databases and multidimensional datasets.

SSIS tools support both the simplest solutions—in which users perform tasks such as copying data from one location to another—and the enterprise-level solutions, in which users develop a large number of complex packages in a team environment.
A workflow is basically a set of instructions that is shared with the Program Executor as a guideline to execute tasks and containers.
A control flow mostly consists of one or more tasks and containers that execute when a package is run. To define conditions for running tasks in the package control flow, precedence constraints are used that connect the tasks and containers in a package.
There are three control flow elements that SSIS provides:
A data flow includes sources and destinations that extract and load data, transformations that modify and extend data, and paths that link sources, transformations, and destinations. The data flow task is executable within SSIS packages that create, order, and run the data flow.

There are three types of major errors in the SSIS landscape, namely:
When the column data is transformed, extracted from sources, or loaded into a destination, errors occur.
Procedure errors are handled in the control flow by the precedence control and by redirecting the execution flow, and data errors are handled in the data flow task by redirecting the data flow using the error output of a component.
The configuration of environmental variables sets package properties equal to the value in an environment variable. These are used to configure properties that are dependent on computers that execute packages.
Different lookup cache modes in SSIS are as follows:

SSIS architecture involves four key parts:
SSIS includes logging features that not only write log entries when run-time events occur but also write custom messages. Integration Services supports a diverse set of log providers and empowers users with the ability to create custom log providers. Integration Services log providers can write log entries into text files, SQL Server Profiler, SQL Server, Windows Event Log, or XML files. The logging configuration provides an in-built feature that can log the details of various events like OnError, OnWarning, etc.

The SSIS project, ‘Build’ offers a deployment manifest file. Users are required to run the manifest file and decide whether to deploy it onto a file system or onto Microsoft SQL Server database. The SQL Server deployment is fast and is also relatively secure than the file system deployment. Alternatively, this deployment can be done from packages in SSMS from the file system or SQL Server.
There are three ways to do so:

Query parameters are revealed in the query of data sources that are to be included in the SQL WHERE clause for accepting parameters. Query parameters begin with the symbol ‘@’.
Variables are used to store values that SSIS packages and their containers, tasks, and event handlers leverage at the run time. Scripts can also use variables. Additionally, precedence constraints that sequence tasks and containers into a workflow use variables when constraint definitions include expressions.
Integration Services supports two types of variables: user-defined variables and system variables.
One of the server-based software systems, SQL Server Reporting Services (SSRS) generates reports developed by Microsoft. It is used for preparing and delivering a variety of interactive printed reports and is administered through an interface that is web-based. It utilizes a web service interface for supporting and developing customized reporting applications.
The architecture of SSRS comprises integrated components. This multi-tiered architecture is scalable and modular. A single installation can be used across multiple computers.
Various components of SSRS architecture include Report Manager, Report Designer, the browser types supported by Reporting Services, Report Server, Report Server command-line utilities, Report Server Database, Report Services Extensibility, and the data sources that are supported by Reporting Services.

SSRS reporting life cycle includes several aspects:
Users should first create a data-driven subscription that uses the Null Delivery Provider. When the Null Delivery Provider is specified as the method of delivery in the subscription, the Report Server targets the Report Server Database as the delivery destination and uses a specialized rendering extension called the null rendering extension. Different from the other delivery extensions, the Null Delivery Provider does not have delivery settings that can be configured through a subscription.

A matrix is a data region that is related to a report set. Matrices permit us to create crosstab reports with the report variables showing on rows and columns.
A sub-report is like any other reports which can be termed in the main report and can be generated through the main report. Parameters can be conceded from the main report to the sub-report, and on basis of that a report can be created.
Report Model Project is used for ad-hoc reporting. We can create ad-hoc reports with Report Builder. Having a simple view, Report Model Project can be created on BIDS or Report Server.

Report Server Project comprises RDL files, and it needs to be deployed on Report Server to view the report files for applications and users. It is a solution where users can design reports. Once the solution is formed, users can start designing reports.
RS.exe utility is used for organizing reports on Report Server. It comes with the Report Server and can be modified accordingly.
In Visual Studio, RDL files have three parts:
Several data sources are used in SSRS for ingesting data:
In order to do this, users need to create a subscription to the report. This can be done with the Report Manager. The report format and the email address of the recipient can be mentioned at Report Subscription. When a schedule is created for the SSRS report, an SQL Server Agent Job will be created. From SSIS, using sp.start_job, the relevant job name can be passed and, henceforth, the SSRS report subscription can be executed.

The middle-tier server for analytical processing, OLAP, and data mining, SSAS manages multidimensional cubes of data and provides access to heaps of information including aggregation of data. Analysis services provide a combined view of data that is used in OLAP or data mining.
Key features of SSAS are:
Unified Dimensional Model (UDM) acts as a bridge between users and data sources.
Benefits of UDM in SSAS:
SSAS has a 2-tier architecture. Below are the key features of SSAS architecture:
There are four languages that are used in SSAS. They are:
Cubes are multidimensional models that store data and aggregations from one or more sources. They are created using the Cube Wizard. Also, dimensions are built while creating cubes.
The writeback dialog box enables or disables writebacks for a measure group in a cube.
Enabling writeback on a measure group defines a writeback partition and creates a writeback table for that measure group.
Disabling writeback on a measure group removes the writeback partition but does not delete the writeback table to avoid unanticipated data loss.
