1. A method, comprising: receiving a request to associate a first template with a first user, wherein templates include instructions that define one or more data analysis strategies; receiving first data associated with a first data collection device, wherein the first data includes: a) one or more first events associated with the first user; and b) one or more first time stamps, wherein each of the one or more first time stamps is associated with at least one of the one or more first events; based on a first data analysis strategy defined by instructions stored in the first template and the first data, generating a first result that conveys information relating to one or more trends involving the one or more first events; receiving a request to associate a second template with the first user; receiving second data, wherein the second data includes: a) one or more second events associated with the first user, wherein each of the one or more second events is a different type of event than the one or more first events; and b) one or more second time stamps, wherein each of the one or more second time stamps is associated with at least one of the one or more second events; based at least in part on the second data and a second data analysis strategy defined by instructions stored in the second template, generating a second result that conveys information relating to one or more trends involving the one or more second events; receiving, from the first user, input that defines a composite reporting strategy, wherein the composite reporting strategy includes: a) relationships between templates and trend categories in a first trend hierarchy; and b) weight metrics associated with one or more templates included in the composite reporting strategy; wherein trend categories represent nodes for organizing templates in a template hierarchy; generating a composite report that includes a trend category metric for each trend category included in the composite reporting strategy based at least in part on the composite reporting strategy, wherein the one or more strategies defined in each template included in the strategy is factored into one or more trend category metrics for one or more related trend categories, wherein the degree to which the strategy of each template is reflected in a trend category metric is based at least in part on the weight metric associated with that template in the composite reporting strategy; wherein the composite report is based at least in part on the first result and the second result; wherein the method is performed by one or more computing devices.
