  9. Analysis ToolPak: The Analysis ToolPak is an Excel add-in program that provides data analysis tools for financial, statistical and engineering data analysis.

POWERPIVOT / POWERQUERY

It seems Microsoft has been running wild recently, throwing “Power” before and “365” after many of their products! For those new to the “Power” suite of Microsoft data collection and analysis tools, it can be difficult to understand exactly what each product does. However, an understanding of the role that each has to play is critical for companies looking to get the most out of their data.

WHAT IS POWER PIVOT?

We’ll start with Power Pivot; the engine of the entire operation. Also known as the DAX Engine (after it’s underlying language – Data Analysis Expression), Power Pivot is a baked-into excel feature that enables users to build a data model, create relationships, write calculated columns and measure formulas from a variety of sources.

In short, Power Pivot extends the capabilities of Excel by allowing for the import of larger data sets from various sources and the creation of more sophisticated data models with DAX.

From Power Pivot you can create visualizations in Excel, Power View and Power Map. Excel allows for the Pivot Tables that we all know and love, while Power Maps is a geography based visualization tool. Finally, Power View is an explorer that shows data on interactive dashboards.

Power Pivot first appeared in 2008, when you had to download a free add-on for Excel. From 2016 onward it can be found in Excel.

WHAT IS POWER QUERY?

PowerQuery is a tool which enables users to retrieve, extract, and shape data prior to bringing it into Excel (and/or into the PowerPivot data model). Users can insert and remove columns, filter and sort tables, and change data types, for example.

Power Query runs on the “M” Language (most-likely named for what it is : Mashup Query Language). Now simply labelled as “Get and Transform,” it can be found under the “Data” Ribbon in Excel.

It should be noted that Power Query is an optional tool. When importing data into Power Pivot you have two choices. You can either import it directly into Power Pivot or you can channel it first through Power Query. Your choice depends on how noisy your initial data is.

POWERBI

Microsoft’s Power BI is business analytics and visualization solution built on the Power Pivot and Power Query engines. Users can use “Get Data” (Power Query) and “Data Model” (Power Pivot) to shape and analyse their data. They can then create interactive dashboards and reports; visualizing their data with Power BI’s every increasing number variety of visualizations. In fact, developers can also build custom visualizations to suit the individual needs of their companies. The uber data geeks out there can even use R scripts for custom visuals.

TABLEAU

At Tableau, we believe in using the visual to drive your analysis. When you get observable feedback as you analyze, the power of exploration is in your hands. When you build an analysis and learn from it simultaneously, opportunities for investigation present themselves. Tableau’s visual analytics makes asking and answering questions of your data intuitive, even as those questions naturally grow in complexity—so you can continue to ask, “Why?”

Immediate understanding

Tableau fuels unlimited data exploration by taking advantage of your natural ability to spot visual patterns quickly. It's all thanks to VizQL, our patented technology that translates drag-and-drop actions into data queries. In other words, we built analytics that work the way you think.

Analytics should be powerful

We believe that to help everyone see and understand data, we need to provide rich capabilities for users of all levels of technical ability. From simple, go-to metrics to advanced analytic techniques, Tableau provides a flexible front-end for data exploration with the necessary analytical depth for the data scientist. By leveraging sophisticated calculations, R and Python integration, rapid cohort analysis, and predictive capabilities, data scientists can conduct complex, quantitative analyses in Tableau, and share visual results to facilitate better understanding and collaboration with data.

MS ACCESS

Very simply, Microsoft Access is an information management tool that helps you store information for reference, reporting, and analysis. Microsoft Access helps you analyze large amounts of information, and manage related data more efficiently than Microsoft Excel or other spreadsheet applications.

WHY SHOULD I USE IT?

All of the things people use as arguments against using MS Access turn out to be reasons for others to use it.

It’s super easy to use – hell yes it is. Setting up tables, queries, forms and reports is a veritable walk in the park. You can import data from spreadsheets, text files or other more suitable data sources like SQL Server and not be afraid of Janey from Accounts overwriting chunks of the production tables with an ill-advised UPDATE statement in Management Studio.

It’s not big enough and my database just kept growing – over time you will eventually max out it’s size limits (somewhere around 2GB from personal observation) but for small scale datasets and quick analysis jobs this will give you more than enough space for very little server space overhead and all you need is MS Access installed on your machine. This should come as standard with most MS Office installs so no fighting with the IT Department to install unwelcome 3rd party software.

It’s not secure enough – well don’t keep business critical or top secret secure data on it in a publicly accessible place then. You don’t need a full user access infrastructure to get started, load it up, fire in your data, run your queries or VBA and it’s all there in front of you.

SQL SERVER MANAGEMENT STUDIO (SSMS)

SQL Server Management Studio (SSMS) is an integrated environment for managing any SQL infrastructure. Use SSMS to access, configure, manage, administer, and develop all components of SQL Server, Azure SQL Database, and SQL Data Warehouse. SSMS provides a single comprehensive utility that combines a broad group of graphical tools with a number of rich script editors to provide access to SQL Server for developers and database administrators of all skill levels.

SQL Server Management Studio for Business Intelligence To access, configure, manage, and administer Analysis Services, Integration Services, and Reporting Services, use SQL Server Management Studio. Although all three business intelligence technologies rely on SQL Server Management Studio, the administrative tasks associated with each of these technologies are slightly different.

Managing Analysis Services Solutions Using SQL Server Management Studio. SQL Server Management Studio enables you to manage Analysis Services objects, such as performing back-ups and processing objects.

Management Studio provides an Analysis Services Script project in which you develop and save scripts written in Multidimensional Expressions (MDX), Data Mining Extensions (DMX), and XML for Analysis (XMLA). You use Analysis Services Scripts projects to perform management tasks or re-create objects, such as database and cubes, on Analysis Services instances. For example, you can develop an XMLA script in an Analysis Services Script project that creates new objects directly on an existing Analysis Services instance. The Analysis Services Scripts projects can be saved as part of a solution and integrated with source code control.

MySQLWorkbench Visualize Explain plans graphically show and highlight how SQL statements execute within MySQL. By showing developers costs and tuning hints, MySQL Workbench improves and simplifies SQL statement performance tuning.

New! Query Statistics

Query Statistics provide instant statistics on SQL executed from the Workbench Editor, such as details about the fields in your result set and key performance statistics from your query, such as client timing, network latency, server execution timing, index usage, number of rows scanned, joins, use of temporary data storage, and more.

BUSINESS LIAISON

Business analyst help guide businesses in improving processes, products, services and software through data analysis. These agile workers straddle the line between IT and the business to help bridge the gap and improve efficiency.

Business analysts (BAs) are responsible for bridging the gap between IT and the business using data analytics to assess processes, determine requirements and deliver data-driven recommendations and reports to executives and stakeholders.

BAs engage with business leaders and users to understand how data-driven changes to process, products, services, software and hardware can improve efficiencies and add value. They must articulate those ideas but also balance them against what’s technologically feasible and financially and functionally reasonable. Depending on the role, you might work with data sets to improve products, hardware, tools, software, services or process.

EXPERT SQL SKILLS

Execution plans

Execution plans are a visual representation of how a database engine executes a query. They basically let you peek under the hood and see how the information sausage is made.Execution plans can tell you a lot about the efficiency of a query and are the main tool for troubleshooting a slow or underperforming query. Reading and understanding them can help you tune queries without messing up performance. Learn how to pull an execution plan, read one, and tune it to increase query performance.

Backup databases

Creating a backup database is crucial in case your first one is corrupted or damaged in some way. There are different types of backups, and knowing which to use and how to institute (and restore) each is an important part of database management.

Using indexes to speed up SQL queries

Indexes can speed up performance by making data quicker to find, but poor indexing is also one of the biggest performance killers. Learning how to to identify good candidates for indexes, as well as how to craft and maintain them, will help you run a quick and orderly database.

OLAP

Online Analytical Processing (OLAP) describes a class of database applications that allow you to analyze data faster and in more innovative ways than you can with just a simple two-dimensional spreadsheet. It used to be done primarily in the form of OLAP cubes but has evolved in recent years to include running OLAP workloads directly on columnar databases.
