I have had a chance to use few other data modeling tools from Quest and Oracle, but I am most comfortable using erwin Data Modeler. They understand your data modeling needs and have designed the software to give you a feeling of completeness when you are designing a data model.

OEM is very well suited for all Oracle products, especially Oracle databases and Exadata machines; even not Oracle hardware, it is very good and displaying high level details. OEM is not well suited for older hardware vendors like AIX, HP-UX, DEC/Digital, Microsoft (sql server). This is a big negative as most large companies have a heterogeneous environment with many different vendor hardware and (database) software products.
Read full review Pros Reverse Engineering: I love the way we can import an SQL file containing schema meta data and generate ER diagram out of it. This is specifically useful if you are implementing erwin Data Modeler for an existing database. Forward Engineering: We use this feature very frequently. Where we do database changes in our physical and logical data models and then generate deployment scripts for the changes made. Physical vs Logical Models: I like to have my database model split into physical and logical models and at the same time still linked to each other. Any changes you make to logical model or physical model shows up in the other. Read full review Database status. Being able to see which databases are up/down, at a glance, allows us to quickly react to issues. Reporting. We report on last backups, daily status, a host of metrics, and compliance levels of all our databases. With reporting we come into the office with a set of "status" reports and we know instantly if a database has issues. Metrics. We have a number of KPI's and SLA's we need to meet. Metrics applied to the databases allow us to stay on top of those requirements as well as fix common issues without a DBA needing to log in to assess the issue. Read full review Cons Cost is the single largest barrier to entry with this tool. Would like to see a greater variety of export options available for use outside of the tool, for example as a vector graphic. Support has been uneven at times. Read full review We also use OEM to monitor SQL Server. However, OEM only provided limited features for SQL Server. It would be nice if we can schedule backup jobs for SQL Server in OEM. The ability to run SQL queries. You can't run queries in OEM. I have to go to SQL Developer or SQL PLUS to run. queries. Read full review Usability
I had a lot of experience using erwin Data Modeler for designing data models. I think it's pretty intuitive and easy to use. It has enough features to represent your database requirements in form of a model.

CA customer support and our account manager have been able to support us with any issues that we have had, from managing our serial keys to issues we logged tickets to resolve. There are aspects of key management that have made it difficult over the years but support usually has worked with us.

I still rate OEM as a must-have tool for central management of Oracle fleet. The pros and cons of the product is prominent. Meanwhile, I also acknowledge that OEM was design about a decade ago. At that time, it did not have the landscape we have today, such as cloud, DEVOPS, machine learning, etc. I hope in future releases, the design will incorporate those features.

Not listed, but I've only used alternatives built into something like the Squirrel SQL editor. That one is semi-functional but lacking many features and, in some instances, just plain wrong. The only pro there is that it's freely available and works over ODBC. I've tried some of the other free ones like Creately but didn't have much success.

is more suited for individual users who have a strong focus on database development, and it is not as comprehensive as Oracle Enterprise Manager. While it is quite decent in logical database layer tasks, such as schema objects and SQL, it lacks visibility into host level and I/O layer performance stats.

I work with OEM SCP team. They are great.
Read full review Return on Investment It is difficult to assign a monetary value to it. The initial learning curve was fairly long. It allows us to have better support documentation. It allows ease of communications between functional units.
