Er studio data architect

Go Up to Main PageER/Studio Business Architect (ER/Studio BA) is a tool for creating a graphical representation of your business -- from the core concepts that describe the business, to the processes that run the business. ER/Studio BA's Process Modeling capabilities allow you to easily model your business processes and how those processes use data. ER/Studio BA Conceptual Modeling provides an intuitive way to outline subject areas and concepts that can then drive the creation of detailed data models.Through robust reporting, modeling, and graphical impact analysis, users are able to provide relevant information to various stakeholders within the organization in a format that makes sense to them. For example, a data analyst may wish to see a CRUD (usage) report showing what data is used by a given process for compliance. A business user may want to see a list of relevant business rules in a spreadsheet. A process modeler needs to see a semantically-rich process model. ER/Studio BA allows each stakeholder to see a different "slice" of information, all from the same data source and metadata model.Contents1 Product Benefits by Audience1.1 Business Process Modelers/Analysts1.2 Data Modelers1.3 Business Users2 TopicsProduct Benefits by AudienceBusiness Process Modelers/AnalystsER/Studio Business Architect provides a rich process modeling semantic based on the Object Management Group's (OMG) Business Process Modeling Notation (BPMN). In addition, modelers and analysts can link their business process models with related business information such as business rules, stewardship, and data to generate impact analysis and usage (CRUD) reports.Data ModelersER/Studio Business Architect's Conceptual modeling allows Data Modelers to create a high-level design of the core business concepts to gain acceptance and requirements from the business. These high-level Conceptual models can be forward and reverse engineered with detailed Logical Data Models in ER/Studio. ER/Studio Business Architect also allows data modelers to relate data objects to business process information, and create Usage (CRUD) and impact analysis reports. In addition to process-specific information, data can also be related to business information such as business rules, stewardship, and business units.Business UsersConceptual Modeling allows Business Users to create high-level designs of the core "concepts" and subject areas that drive the business, which can be passed onto data and process modelers to drive more detailed logical and physical design. ER/Studio Business Architect also provides intuitive reporting and export capabilities to provide relevant information to business users in an easy-to-understand format. Intuitive impact analysis diagrams and reports allow business users to get an understanding of the relationship between business information and key IT assets such as data, without having to be a modeling or programming expert. Information can be shared with business users in formats they are familiar with: Excel spreadsheets, HTML reports, PDF files, etc.TopicsWhat's New in ER/Studio BAProduct Resources

Request Demo Request Quote Frequently-Asked Questions Database modeling tools streamline and improve the process of creating a data model, also called a logical database structure, offering robust functionality to support SQL scripts, provide code automation, offer consistency across databases and models, and perform impact analyses on changes at the database level. There are open-source data modeling tools, but they generally don't offer the robust functionality and high-quality user experience required by most modern enterprises. Idera’s ER/Studio facilitates seamless collaboration among stakeholders across an organization, particularly due to the model repository, which allows for robust version control and agile change management across a team. Data modeling allows organizations to translate business requirements and knowledge into an organized conceptual data model, forming the cornerstone of business intelligence (BI). Clearly-modeled data enables organizations to make informed decisions and knowledgeable predictions. The Model Repository for ER/Studio Data Architect Professional provides modelers with real-time collaboration features for sharing and re-using assets across data modeling projects. ER/Studio Data Architect users can connect to the same repository to work on models simultaneously and leverage features including an enterprise data dictionary (EDD), version control, and change management. Repository-based collaborative modeling provides modeling teams significant advantages, including: Controlled access to data models and projects in a collaborative environment Ability to display, access, and reuse common elements across models Granular check-out and check-in of diagrams, sub-models, and objects Conflict resolution at check-in to eliminate model differences Alignment of modeling changes to development tasks and workflows Clear and effective change tracking and audit trail for compliance Version management for objects and models with named releases Secure access to

All assets to maintain data model integrity and privacy A "good" data model is one that can be easily consumed, is scalable, provides reliably predictable performance, and is agile, able to adapt to changes in requirements. A data model in SQL is a means of organizing and representing data stored in a SQL database, such as SQLite, SqlDBM, PostgreSQL, or Microsoft SQL Server. Data models ensure consistency in naming conventions, security, and semantics, making it easier to ensure data quality and more intuitive to work with the data. ER/Studio Data Architect Professional Product Benefits Document, design, and communicate data assets faster and easier Round-trip database support gives ER/Studio Data Architect users the power to easily reverse- and forward-engineer, compare and merge, and visually document data assets across multiple relational, NoSQL, and ETL platforms and data sources. Built-in facilities automate routine data modeling tasks so users can analyze and optimize database and data warehouse designs faster than ever. Group multiple entities aligned to a specific area into a Business Data Object Create Business Data Objects by assigning one or more related entities to a BDO. Then, users can easily view attributes, definitions, or other information about the entities in the objects. These BDOs are then reusable objects that can be used in other submodels within the model. Users can quickly expand or collapse a Business Data Object (BDO) to simplify the model view for different end users and audiences. Streamline collaboration on data models in a team environment through a shared repository The Repository (included with ER/Studio Data Architect Professional) provides a secure and scalable environment for model and object version management and change management. Data modeling teams can check-out and check-in portions of the same model to work collaboratively within the repository, and easily identify which model objects have been checked in using the model explorer tree. Easily compare differences between two data models or databases, and merge changes between them ER/Studio Data Architect’s Compare and Merge wizard helps you reduce duplication and risk associated with multiple data sources and platforms. Quickly compare data models and databases to identify differences, and determine whether to merge differences to the source or the target. ER/Studio generates the Alter scripts to implement the changes for a database. Manage and track model changes against user stories or tasks In ER/Studio Data Architect Professional, data modelers can create change records to represent user stories or

(and version).A logical model of another ER/Studio Data Architect data model.A physical model of another ER/Studio Data Architect data model sharing the same DBMS platform (and version).A live database.An SQL file.When comparing two physical models, make sure they are the same platform and version (i.e. Oracle 11g to Oracle 11g). if they are not the same, then you will only be able to compare to the logical. If you want to compare Oracle to SQL Server, you would need to compare to the logical model from the reverse engineered physical database, then push the changes from the logical model to the original physical model.You can compare and merge a submodel to:A submodel of the same data model.The physical model of the same data model.An SQL file.The broad spectrum of valid targets allows for various information-merging strategies. For example, information in the Compare and Merge utility can be:Merged from the current model to a valid target.Merged from the valid target to the current model.Bi-directionally merged simultaneously between source and valid target.Note: Objects in SQL 2005 are owned by schemas. A schema can behave like a user, but does not have to be a user. A schema is not explicitly represented in the Data Model Explorer, nor is there a CREATE SCHEMA DDL function. In the Reverse Engineering and Compare/Merge Wizards, the "owner" field in the object editors of ER/Studio Data Architect represents the schema name for an SQL Server 2005 physical model. The field will be the schema list.A subset of the functionality on the Compare and Merge utility is used to bring new data source into the diagram for purposes of importing new data sources from the Data Lineage tab.Note: There are instances as previously noted that during compare/merge the alter code generated renames a table, creating a new table with the updated structure and reads data from the old (renamed) table into the new table. This is called an extended alter and can happen if for instance you have added a column to somewhere other than the end of the table or chose a child table but did not

For example, you have designed and created a model and then created a database based on that data model. A data modeler alters the model and adds a column Gender to the Employee table and simultaneously a DBA alters the Department table in the database and adds a column Name to the table. The model and the database are no longer in synch. Round-trip engineering using the Compare and Merge utility can now help you reconcile the model with the database.The Compare and Merge utility compares, merges, and synchronizes models from a variety of comparison targets. It can perform different kinds of comparisons. You can use the information from these comparisons to perform merges or to create detailed reports.The Compare and Merge utility compares a source and a target model. The active diagram, the one you are viewing and editing, will always be the source, and from it you select a valid target with which to compare and subsequently merges if desired, or to create alter sql to update offline databases.Note: Targets of logical and physical ER/Studio Data Architect data models can be Repository-based data models including named releases, which are read-only archived snapshots of diagrams managed within the Repository.You can compare and merge a logical model to:A physical model in the same.dm1 file.A logical model of another ER/Studio Data Architect data model.A physical model of another ER/Studio Data Architect data model.You can compare and merge a physical model to:The logical model of the same data model.Another physical model of the same data model that shares the same DBMS platform
