What is operationalisation and conceptualisation?
Conceptualization, Operationalization, and MeasurementCharles W. MuellerResearch begins with a "problem" or topic. Thinking about the problem results in identifying concepts that capture the phenomenon being studied. Concepts, or CONSTRUCTS , are ideas that represent the phenomenon. Conceptualization is the process whereby these concepts are given theoretical meaning. The process typically involves defining the concepts abstractly in theoretical terms. Describing social phenomena and testing hypotheses require that concept(s) be operationalized. Operationalization moves the researcher from the abstract level to the empirical level, where variables rather than concepts are the focus. It refers to the operations or procedures needed to measure the concept(s). Measurement is the process by which numerals (or some other labels) are attached to levels or characteristics of the variables. The actual research then involves empirically studying the variables to make statements (descriptive, relational, or causal) about the concepts

Are there any major similiarities between object oriented databases and relational databases?
In a Object Oriented Database, information is given in the form of objects as used in programming languages. "When database capabilities are combined with object programming language capabilities, the result is an object database management system (ODBMS). An ODBMS makes database objects appear as programming language objects in one or more object programming languages." (http://en.wikipedia.org/wiki/Object_database)"A relational database is a database that conforms to the relational model, and refers to a database's data and schema (the database's structure of how those data are arranged). Common usage of the term "Relational database management system" technically refers to the software used to create a relational database, but sometimes mistakenly refers to a relational database."
