Universal and adaptive software development platform for data-driven applications

A persistence layer system for providing a computer software application uniform and dynamic access to a physical storage medium, comprising:

• a connection object configured to communicate data records between a file system or database residing on the storage medium and the application program residing in transient computer memory wherein the connection object includes functions to load, find, save, create and synchronize record objects with corresponding entries in the storage medium and functions to initiate and end storage sessions and ensure exclusive access to storage medium resources;
• wherein further the connection object initiates transactions with and communicates commands to the storage medium;
• a connection definition object configured to use the connection object to read meta record information from the file system or database wherein the meta record information includes record type and record structure;
• a plurality of record objects wherein each record object includes connection object origination information, a meta record object containing information describing the record object structure, record field values, and functions to get and set field values, field names, field attributes and a record state that indicates a stage of a record life cycle;
• wherein the connection definition object includes functions to retrieve information relevant to creating meta records dynamically;
• wherein each meta record object corresponds to an object n the storage medium and includes one or more of field names and field types;
• a plurality of entity objects wherein each entity object is configured to enforce data coherence rules over a set of related record objects and data fields;
• wherein each entity object includes a meta entity object containing information describing the entity object structure and containing at least one meta record object;
• wherein each entity object includes one or more default field values;
• wherein each entity object is configured at runtime to accept instructions to modify one or more data fields consistent with the data coherence rules;
• wherein each entity object provides a plugin mechanism to allow changes to be performed before and after life cycle events;
• and
• wherein each entity object is configured at runtime to validate data field values.

A record management system for managing information in a computer software application running on a computing device, comprising:

• a persistence layer capable of providing the computer software application uniform and dynamic access to a database residing on a physical storage medium;
• a detail object configured at runtime to coordinate and manipulate a set of fields within an entity object wherein the detail object also allows custom operations to be infused and executed on the entity object;
• a directory object configured at runtime to coordinate and manipulate a set of entity objects, wherein the directory object includes:
• (a) a connection with the persistence layer,
• (b) a detail object,
• (c) a filter manager and at least one filter configured to extract a subset of entity objects to be displayed,
• (d) a parameter set with no or multiple parameters, wherein parameters capture field names and values by which to search, wherein the values are infused into the filter as conditions,
• (e) a keeper object configured to generate one or more data models and one or more data views and which is used for generating views and models at runtime,
• (f) a navigation model object configured to control the means for browsing through the set of available entity objects,
• (g) a table entity face object configured at runtime by the filter object to store a page of the set of entity objects, and
• (h) a lookup manager configured at runtime to manage a plurality of lookup objects wherein lookup objects are used to replace field values containing references with interpretable values;
• wherein multiple directory objects can be assigned a single detail view by one or more owner relationship objects which indicate the fields by which entity objects are related;
• a directory view object associated with the directory object, configured to construct itself at runtime based upon the set of entity objects, and further comprising a plurality of sub-view objects, wherein the directory view and subviews are capable of reflecting any changes in the underlying directory objects and field definitions in the database;
• wherein the directory view generates a subview for each object included in the directory including but not limited to a parameter view, a filter manager view, a parameter set view, a navigation view and a table view object wherein each subview is associated with the correspondingly named object from the directory object and wherein the subviews are generated at runtime using the keeper object;
• wherein the directory view object and its subviews are configured to receive input signals from a user to modify one or more of the parameters in the parameter set, at least one filter, the set of entity objects, the page, and the table entity face object and to relay the signals to the directory object or relevant sub-object;
• and
• wherein the directory view object is further configured to create a detail view object in response to a signal from a user interface object wherein the detail view object is associated with the detail object.
