There are many programs that can be used to analyse secondary data. These programs allow users to view and prepare data, perform analyses, create visualisations, and more. This page provides resources for learning to use several commonly used statistical software programs, as well as resources for spatial data analysis and database management.
Most researchers learn to use one or more data software programs and mastering one of these programs requires considerable time and effort. When choosing which program to learn, you will want to consider your financial resources and institutional affiliations; the programs commonly used in your field; the programs used by your research collaborators; and your own research goals. Some of these programs are proprietary so you will need to pay for access or gain access through your institution. Excel, SPSS, SAS, Stata, and MPlus are all proprietary programs (though Google Sheets is a free program that has some of the functionality of Excel). R and Python are free, open-source programs. If you are interested in analysis of geospatial data, you may want to learn to use ArcGIS or an open-source counterpart like QGIS. If you are managing a large amount of data, you may want to learn to use SQL and a relational database management system.

Software for storing and managing data
A database is a dataset or multiple datasets stored on a computer. A relational database is a database that stores data in tables. Relational database management systems can be used to manage large, complex data tables. If you are managing a large amount of data, you may want to use a relational database management system to manage and query your data. Structured query language (SQL) is a programming language used in many relational database management systems.
