Types of the models Before that what proceed with study DBMS ACCESS consider several main notions. Given - systematized and outline some image information. Exist, at least once, three models given: hierarchical, network, relational. The Models given - a presentation data and their intercoupling, describing notions of the problem-solving ambience. The Models given are used both for conceptual, and for logical and physical presentation data. The Hierarchical outline data consist of several records, one of which is determined as rhizome. The Example to hierarchical model can serve the tree: where CLIENT, ORDER, COMMERCIAL AGENT are a record (the CLIENT - a rhizome record), NUMBER, SURNAME, NAME, PATRONYMIC NAME - a field record CLIENT, line are shown relationship. The Tree - oriented earl(the earl - a pair ensemble, one of which describes the ensemble of the tops, but the other ensemble of the relationships between them) where all tops, except root, are found in head only one arcs, root is not found in head nor one of the arcs and is connected with top tree. Between record in hierarchies can be determined relationship: "one to many", or "head-to-head", where record corresponding to element "one" specified relationship, is defined as source, but corresponding to element "much" - as generated. The Network model is befitted hierarchical, but is more general model, to the extent that that between record are present the relationship "much to many" and "much to one", but in the same way here no root node i.e. any record can be root. The Reports. The Report this information, which You have arranged in accordance with Your specification.

The Project of the report will remain unchangeable, but every time You will get the printout current data.
