Description

    FIELD OF THE INVENTION
  • The present invention relates generally to computer-based methods and apparatuses, including computer program products, for declarative and unified data transition.
  • BACKGROUND
  • Data transition, such as in system integration or ETL (extract, transform, and load) processes, is generally described as a list of steps of a whole process, i.e. in an imperative process. In implementing this list of steps, a knowledge domain is spread among all steps of the process. For example, in an extract step, where to put the data is described, in a validation step, what to check is described, and in a reconciliation step, what to transform is described. In other words, the same knowledge domain is partially described in every step of the data transformation. This repeating of knowledge definition(s) increases modeling time for the system, decreases reusability, and causes errors in knowledge consistency and integrity.
  • Thus, a need exists in the art for improved declarative and unified data transformation.

  • DETAILED DESCRIPTION
  • Declarative and unified data transition technology enables a description of a knowledge domain to be made once and utilized a plurality of times for the transition of data. The technology can manage the knowledge domain for the transition process by enabling the knowledge domain to be defined by users and/or administrators of the technology (e.g., add information, edit information, delete information, setup a template, etc.) and/or by generating the knowledge domain based on other processes and/or relationships. The knowledge domain can be declaratively described in an unified configuration. The unified configuration can include one or more predicates (e.g., <relationship name=“Frame to Device” multiplicity=“0 . . . 1” direction=“in”>, <relationship name=“Card to Device” multiplicity=“0 . . . 1” direction=“in”>, etc.) for one or more system objects (e.g., components of a system, devices of a system, cards of a system, entities of a system, parts of a system, etc.) and/or one or more relationships between the one or more system objects (e.g., card A is related to card B, cards A and B are part of device 1, etc.). The unified configuration of the knowledge domain can be, for example, organized in a multi-level hierarchy (e.g., a set of objects, a single object, a set of object attributes, single attributes, etc.).
  • The technology can centrally manage the knowledge domain for all of the components in the transition process. The components can include a validation step (e.g., check data against a set of validation rules, verify that data matches a particular criteria, etc.), a transformation step (e.g., convert information from a first database structure to a second database structure, convert data into an intermediate database format, etc.), and a reconciliation step (e.g., merge data to an existing destination database, merge data to a plurality of existing destination databases, overwrite data to an existing destination database, ignore data during the reconciliation to an existing destination database, append data to an existing destination database, etc.). In some examples, the components include a data extraction process and/or one or more validation steps (e.g., post-transformation validation step, post-reconciliation validation step, etc.). The transition process can occur in real-time or near real-time to enable the efficient transition of the data (i.e., the validation step, the transformation step, and the reconciliation step occur in real-time or near real-time).
  • The technology can include the unified configuration for the knowledge domain that includes the one or more predicates and/or the centralized knowledge base. The one or more predicates can be described utilizing metadata to describe a business domain (e.g., operational support system, information technology system, healthcare system, customer service system, enterprise resource planning system, accounting system, etc.) and/or can include predicates about all involved objects (e.g., entities, components, parts, etc.) and their relationships. The centralized knowledge base can be utilized by the steps of the integration process, including the validation step, the transformation step, and/or the reconciliation step. Another advantage to the data transformation process is that the one or more predicates and/or the centralized knowledge base enable the technology to be configurable, scalable, and applicable to broad business cases (e.g., integration of two or more systems, mirroring of data between two or more systems, etc.).
  • FIG. 1 is a diagram of an exemplary system 100. The system 100 includes a mediation transition system 110, an operational support system database 125, an operational support system 120, and a plurality of external system databases A 140 a, B 140 b, C 140 c through Z 140 z (generally referred to as 140). The mediation transition system 110, the operational support system database 125, the operational support system 120, and/or the plurality of external system databases 140 can communicate via one or more connections (e.g., a direct network connection, an indirect network connection, an external storage connection, etc.). The mediation transition system 110 can extract data from one or more of the plurality of external system databases 140, validate the extracted data, transform the validated data, and/or reconcile the validated transformed data with data stored on the operational support system database 125. The mediation transition system 110 can extract, validate, transform, and/or reconcile the data based on a unified configuration of a knowledge domain (e.g., operational support system knowledge domain, information technology system knowledge domain, etc.).
  • Although FIG. 1 illustrates the operational support system database 125 and the operational support system 120, the system 100 can be utilized for any type of application system (e.g., information technology system, telephone system, network management system, healthcare system, etc.).
  • FIG. 2 is a diagram of an exemplary mediation transition system 210. The mediation transition system 210 includes a source extraction rule engine 211, a source extraction module 212, a unified configuration module 213, a validation rules engine 214, a validation module 215, a transformation rules engine 216, a transformation module 217, a reconciliation rules engine 218, a reconciliation module 219, an input device 221, an output device 222, a display device 223, a communication module 224, a processor 225, and a storage device. The modules and devices described herein can, for example, utilize the processor 225 to execute computer executable instructions and/or include a processor to execute computer executable instructions (e.g., an encryption processing unit, a field programmable gate array processing unit, etc.). It should be understood that the mediation transition system 210 can include, for example, other modules, devices, and/or processors known in the art and/or varieties of the illustrated modules, devices, and/or processors.
  • The source extraction rule engine 211 generates one or more extraction rules based on the one or more predicates. The source extraction rule engine 211 can generate (e.g., determine, modify, create, define, etc.) the one or more extraction rules based on the one or more predicates, the unified configuration, and/or other stored information (e.g., data from another unified configuration, data from another knowledge domain, etc.). The one or more extraction rules can include information that identifies tables, columns, rows, lines, identifiers, and/or roles where the input data is stored (e.g., user identification data is stored in the User_ID table, user names are stored in the User_Name column, etc.)
  • The source extraction module 212 extracts input data (also referred to as source database (SDB)) from one or more source databases (e.g., plain text file, organized data, file of data, marked-up data, commercially available database system, enterprise database, relational database, non-relational database, XML-based database, read-only database, non-standard meta-model driven database, etc.) based on one or more extraction rules (e.g., SELECT * from User_ID; SELECT * from User_Name WHERE ID=0; etc.).
  • The unified configuration module 213 determines an unified configuration for knowledge domain. The unified configuration includes one or more predicates for one or more system objects (e.g., doctor identification includes licensed states, patient identification includes mailing address, etc.) and/or one or more relationships between the one or more system objects (e.g., patient identification includes primary healthcare provider identification, doctor identification includes hospital identification, etc.).
  • The validation rules engine 214 generates one or more validation rules based on the one or more predicates and/or generates one or more post-transformation validation rules based on the one or more predicates. The validation rule engine 214 can generate (e.g., determine, modify, create, define, etc.) the one or more validation rules based on the on the one or more predicates, the unified configuration, and/or other stored information (e.g., data from another unified configuration, data from another knowledge domain, transformation rules, reconciliation rules, operational support system model, destination system model, database constraints, customized validations, etc.). For example, the validation rule engine 214 determines one or more validation rules based on the reconciliation rules associated with a destination database (e.g., specified syntax, specified data structure, etc.). The one or more validation rules can include number checks (e.g., integer check, minimum number, maximum number, etc.), null checks, key multiplicity, primary key validation, row-level validation, length validation, and/or any other type of input validation (e.g., number, character, word, sentence, logical expression, etc.).
  • The validation module 215 validates the input data based on the one or more validation rules (e.g., is the data an integer, is the data above the number ten, etc.) and/or validates the transformed data based on the one or more post-transformation validation rules. The validation module 215 can automatically modify the input data based on the validation of the input data to remove at least one validation error associated with the input data (e.g., convert a written number to a numerically number, convert a real number to an integer, determine input for NULL data, delete the row/column/data, etc.). In other examples, the validation module 215 can report any validation errors.
  • The transformation rules engine 216 generates one or more transformation rules based on the one or more predicates. The transformation rule engine 216 can generate (e.g., determine, modify, create, define, etc.) the one or more transformation rules based on the on the one or more predicates, the unified configuration, and/or other stored information (e.g., data from another unified configuration, data from another knowledge domain, validation rules, reconciliation rules, operational support system model, destination system model, database constraints, customized transformations, etc.). The one or more transformations can enable the transformation of input data into transformed data (also referred to as intermediate database (IDB)). The input data can include information associated with the one or more system objects and/or the one or more relationships between the one or more system objects.
  • The transformation module 217 transforms input data based on the one or more transformation rules, transform second input data based on the one or more transformation rules, and/or transform any number of input data based on the one or more transformation rules. The second input data including information associated with the one or more system objects and/or the one or more relationships between the one or more system objects. The transformation module 217 can join at least one part of the input data with at least one other part of the input data based on the one or more transformation rules (e.g., join User table with Patient table, join User column with Doctor column, etc.). The transformation module 217 can merge at least one part of the input data with at least one other part of the input data based on the one or more transformation rules (e.g., merge User table with Patient table for all active Users, merge Doctor column with Hospital column for all Doctors grossing over $1 million per year, etc.). The transformation module 217 can modify at least one part of the input data based on the one or more transformation rules (e.g., delete a part of the input data, convert numbers, etc.).
  • The reconciliation rules engine 218 generates one or more reconciliation rules based on the one or more predicates. The one or more reconciliation rules can be associated with a destination database (e.g., plain text file, organized data, file of data, marked-up data, commercially available database system, enterprise database, relational database, non-relational database, XML-based database, write-once database, non-standard meta-model driven database, etc.). The reconciliation rules engine 218 can generate one or more second reconciliation rules based on the one or more predicates. The one or more second reconciliation rules can be associated with a second destination database. The one or more reconciliation rules and/or the one or more second reconciliation rules can enable reconciliation of the transformed data with the destination database.
  • The reconciliation module 219 reconciles the transformed data with the destination database based on the one or more reconciliation rules and/or reconciles the second transformed data with the destination database based on the one or more reconciliation rules. The reconciliation module 219 can reconcile the transformed data with the second destination database based on the one or more second reconciliation rules. The reconciliation module 219 can merge the reconciled data with data stored on the destination database (e.g., combine parts of the reconciled data with parts of the data stored on the destination database, transformation rules, validation rules, operational support system model, destination system model, database constraints, customized validations, etc.).

It should be understood that the operational support system 320 can include, for example, other modules, devices, and/or processors known in the art and/or varieties of the illustrated modules, devices, and/or processors.
  • The communication module 224 receives the reconciled data and/or transmits the output data (e.g., data utilized as input data by the mediation transition system, etc.). The database interface module 322 communicates with the storage device 335, an operational support system database, and/or one or more other external databases. The service inventory module 323 manages the service inventory for the operational support system 320 (e.g., receives updates to the service inventory, transmits updates to the service inventory, etc.).

  • FIG. 4 is a flow diagram 400 of an exemplary process for data transition. An external extraction module 420 extracts input data 428 from source data 410 (e.g., from external storage such as a text file, from a database, from an external device and system utilizing a protocol such as simple network management protocol (SNMP) and/or a command line interface (CLI), etc). A unified configuration module (not shown) generates validation rules 434, transformation rules 444, and reconciliation rules 454 based on a data definition 474. The validation rules 434, the transformation rules 444, the reconciliation rules 454, and the data definition 474 are an unified configuration 470.
  • A validation module 430 validates the input data 428 to form validated data 438 based on the validation rules 434. A transformation module 440 transforms the validated data 438 to transformed data 448 based on the transformation rules 444. A reconciliation module 450 reconciles the transformed data 448 into a destination data 460 via reconciled data 458 based on the reconciliation rules 454.
  • In some examples, the unified configuration 470 describes system objects (e.g., entities, components, etc.) and their relationships. The unified configuration 470 can specify extra parameters for the system objects which add information in one or more knowledge domains. The knowledge domains can be stored in a configuration in an unified independent manner (e.g., for XML, each knowledge domain is in a different XML namespace). The knowledge domain can include one or more predicates that provide information regarding the behavior of different processes. For example, the predicates includes information about how to obtain data for an entity, information about how to check consistency, and information about how to load data into a destination database. Each process step can define how it interprets data in a specific knowledge domain. The unified configuration can include extra declarations and/or create special processes for the extra declarations. For example, the extra declarations include how to load data into database tables from simple network management protocol (SNMP) agents or lightweight directory access protocol (LDAP).
  • In other examples, the unified configuration 470 enables a user and/or an administrator to describe once the domain knowledge of the transition, in one place, and then map it to source database, to the destination database, and/or rules for checking consistency of the data. The technology described herein can be utilized for various types of integration and/or migration, such as mapping a data model to SNMP, mapping a read-only database to a legacy element management service (EMS), etc.

The unified configuration 600 b includes source database (SDB) configuration 610 b and intermediate database (IDB) configuration 620 b. The unified configuration 600 b describes a knowledge domain (KD). The unified configuration 600 b can include system objects (e.g., entities such as BSC Board and/or Card, etc.) associated with the KD, attributes of the system objects, relationships between system objects, and/or multiplicity of the relationships. The system object set (e.g., entity set) can be a container that provides capabilities to specify system object settings and references that utilized to prepare the validation, the transformation, and/or the reconciliation process. The system object can include one or more attributes (e.g., a primary key attribute which is a unique attribute which identifies the system object). Every attribute can be defined by the attribute type. Attributes from different system objects can be involved in relationships with uni-, in- and/or or out-directions.
  • FIG. 6C is exemplary validation rules 600 c. The validation rules 600 c include the SDB configuration as illustrated above in the unified configuration 600 b and three validation rules 610 c, 620 c, and 630 c.

  • In some examples, the validation rules can be defined on every level of the KD (e.g., attribute, entity, entity-set, etc.). The attribute-level validation rules 610 c, 620 c, and 630 c check values of concrete attribute on a given entity. In some example, the “Between” rule checks whether the attribute value is in the range specified by the values of the “min” and “max” parameters. In other examples, the “Is Not Null” rule checks whether the attribute value is not null. In some examples, the “Regular Expression” rule checks the attribute value against the mask specified by the value of the “expression” parameter.

As illustrated, the transformation rule 630 e merges BSCFrame Serial Number and the BSCCard Serial Number together to form the Name field for the Card entity.
  • In some examples, the transformation rules are defined on every level of the KD. The transformation rules engine 216 can define one “transformation” session from SDB to IDB and one transformation expression (rule) on the attribute “Name.” Every transformation can be defined for source entities in the SDB. In other examples, destination expressions define mapping among source and destination attributes and/or can express destination attribute value using special merge-rule. In some examples, a join condition is the equal condition of two source entities for joining into result. In other examples, data from source entities can be filtered using special filter by attribute value.

  • For example, the transition process described in FIG. 12 transitions parts of the first data and the second data with an OSS database and parts of the first data and the second data with a customer billing database from a customer service database. In other words, in this example, source data from a plurality of sources is transitioned to a destination database. In other examples, source data from a plurality of sources is transitioned to a plurality of destination databases.

  • In other examples, the transformation rules generation and execution, the validation rules generation and execution, the reconciliation rules generation and execution, and/or other data transition operations can occur in any order and/or any sequence utilizing the unified configuration. For example, the data transition can occur as follow: input data from four source databases is extracted based on two sets of one or more extraction rules; the input data from each source database is validated based on a single set of one or more validation rules; the validated data from each source database is transformed based on two sets of one or more transformation rules; the two sets of transformed data is further transformed based on one set of one or more combined transformation rules; the combined set of transformed data is reconciled with two destination databases based on a single set of one or more reconciliation rules; and the transformed data from each source database is reconciled to four different destination databases based on four different sets of one or more reconciliation rules. In this example, the data is transitioned between a plurality of source databases to a plurality of destination databases based on various rules and/or in various orders. Other examples of the number of rules and/or sequence of the order of the rule generation and/or execution can be utilized by the technology described herein.
  • In other examples, the technology enables the reuse of the knowledge domain via use of declarative style in configuration definition, thereby reducing the need for custom programming and increasing the efficiency of the transformation process. In other words, in some examples, the knowledge domains and rules are not coded inside a module and/or engine. The knowledge domains and/or rules can be used by other module and/or engine. In other examples, the modules and/or engines can use part of the unified configuration based on the need of the module/engine (e.g., use only SONET/SDH domain and ignore VPN domain, etc).
  • In some examples, the knowledge domain can be described regardless of its specific implementations (e.g., physical implementation, logical implementation, etc.). In this example, rules can be reused for different transformation projects, regardless if the rules are from Excel to MS SQL, Oracle to DB2, or MySQL to Informix, etc.
  • In other examples, the technology includes knowledge domain and/or rules management tools. The tools can enable easy configuration and/or export/import in any representation format. The technology can include a configuration editor. The configuration editor can include a knowledge domain editor, a rules editor, and/or a “Meta-rules” editor for validating of rules.
  • In some examples, the validation rules can include one or more entities definition checking (e.g., primary key existence, no duplicated attributes, etc.), relationships integrity checking (e.g., no duplication of relations, no circle relations with multiplicity impact, etc.), validation rules checking against schema definition (e.g., no contradiction of rules in schema and in entity set, etc.), and/or reconciliation rules checking against integrity with schema (e.g., existence of all required attributes and object-types, no cycle in parent-child relationships, etc.).
  • In other examples, the technology described herein can synchronize data between two or more data sources (e.g., databases, files, etc.). For example, the technology can be utilized to synchronize customer data between a customer relationship system and an operational support system. In some examples, the one or more destination databases can be, for example, any type (e.g., a relational DB, an object DB, an XML-based DB, a metadata-driven database, etc.).
  • In some examples, the technology described herein can utilize the following exemplary data definition: input data (SDB), validation rules, validated input data, transformation rules, transformed data, post-transformation validation rules, validated transformed data, reconciliation rules, and reconciled data.
