First post for 2014. After almost 2 years of blog­ging, I want to reshape the blog a bit. There are three steps to mak­ing data dri­ven deci­sions: 1) Col­lect, aggre­gate, and process the right data. 2) Ana­lyze, orga­nize, and visu­al­ize to begin to find mean­ing. 3) Get insights, draw con­clu­sions, and take action Begin­ning in […]

Power­pivot is an addin for Microsoft Excel which enables analy­sis of larger data sets (>1M rows) within Excel and also more sophis­ti­cated analy­sis that typ­i­cally would involve mul­ti­ple SQL queries with com­plex data joins. I blogged about learn­ing Pow­er­pivot last year. One of the dif­fi­cult things is the lack of usable doc­u­men­ta­tion or cook­books on […]
