Database system for dynamic and automated access and storage of data items from multiple data sources

A computing system for dynamically accessing and integrating data items from one or more data sources or databases, the computing system comprising:

• one or more data stores storing:
• a plurality of analysis models, and
• a plurality of user data items in one or more databases;
• one or more computer processors;
• and
• a computer readable storage medium storing program instructions configured for execution by the one or more computer processors in order to cause the computing system to:
• receive analysis criteria including a user data item;
• store the first user data item in the one or more databases as one of the plurality of user data items;
• select, from the plurality of analysis models and based on the user data item, an analysis model, wherein:
• the analysis model defines a plurality of factors,
• the analysis model further defines a plurality of attributes, and
• each of the plurality of attributes is associated with at least one of the plurality of factors;
• determine, for each of the plurality of attributes, and based on at least some of the plurality of user data items, an attribute score;
• determine, for each factor of the plurality of factors, and based on the attribute scores of attributes associated with the factor, a factor score;
• combine, as indicated by the analysis model, the factor scores to determine an analysis score;
• determine, based on at least some of the plurality of user data items, an industry;
• determine, based on the industry and at least some of the plurality user data items, an industry code;
• determine, based on the industry code and at least some of the plurality of user data items, a minimum multiple and a maximum multiple;
• and
• determine an estimated multiple, based on the minimum multiple, the maximum multiple, and the analysis score.
