Oracle SQL Developer is an integrated development environment (IDE) which provides editors for working with SQL, PL/SQL, Stored Java Procedures, and XML in Oracle databases.
I wish I had an option to give it a 9.5 :) OEM Cloud Control is very well suited if you have a system with multiple implementations of Oracle Database Enterprise Edition. If you are willing to pay for the huge license cost which is typical with Oracle, then you will love to use OEM Cloud Control to monitor your entire ERP solution including web servers, applications, network, storage, and physical servers. It is not worth the buck if your's is a small implementation. Your DBA's should be able to work without depending on OEM Cloud Control.
[Oracle SQL Developer is] best suited if your company works with different databases and needs a common SQL editor to manage and query data for its user. Oracle SQL Developer works very well with Oracle but also some other relational databases. If you do lot of querying and import/export in database, then this is tool for you. It's ideal for DBAs as well for data modeling, management, session monitoring, logging, versioning, etc. It’s not ideal for no relational/noSQL or big data. It is not tool for visualization. It’s best suited for querying using SQL. Companies that are looking for free tools that are robust and most useful should definitely look at it.
Oracle Enterprise Manager is a "one stop shop" for all of our management needs. This is helpful because it minimizes the management of the management software itself. There are less upgrades and connectivity issues to handle. And there are "plug-ins" for additional products we use like Blue Medora's one for PostgreSQL.
Managing administrative jobs can be burdensome in a shop with dozens of servers and databases. OEM Cloud Control makes it easy since you can view all the jobs for all servers in one place. It is easy to filter on jobs with problems or the like so that you can quickly look at the logs and fix the issues.
Tuning PL/SQL is much easier using OEM Cloud Control. Most DBAs are familiar with trace files and TKPROF, but not having to do those things at a command line smooths the process out. The graphical interface makes it easier to show developers exactly what the issues are. This makes for less finger-pointing and quicker resolution of performance problems.
Proactive management is easier using OEM Cloud Control. Before having the gui, I had a collection of scripts that I would have to install on each database server, then set up cron jobs to run them. When Oracle was upgraded, those scripts might have to be updated on each and every server. OEM Cloud Control has those things built in. You can choose exactly which metrics are important to you. And you can keep performance graphs up all day on a second monitor to let you instantly see when something might cause a problem.
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.
Setup can be challenging if your schemas aren't well formed or managed. Also, the ability to model/develop extensions for an existing database solution will depend on how robust the DBA provisioned roles and designed the respective schemas.
Detailed analysis of models can be clunky for complex relational models.
It's great! It does everything and anything you would want it to do. It can monitor things which doesn't comes out of the box by adding plug ins to it, for example, you can even monitor Oracle GoldenGate Replication by adding a plug-in to OEM Cloud Control.
Oracle SQL Developer is very easy to use and there are a wide range of courses available which can help you get started just within a day. Data can be exported in multiple formats based on user requirements. Organizational data can be stored and management effectively using Oracle SQL Developer. All the data, tables, sequences, indexes can be easily created and updated in Oracle SQL Developer.
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.
Kibana from Elastic is another monitoring tool that claims to provide very similar information to OEM. It seems to be an information tool rather than a tool that can actually make changes within a database. I think Kibana is more robust for hardware versus database software so it is more suited to that purpose and does to compare to the Oracle Database monitoring attributes of OEM.
Oracle SQL Developer is available on multiple platforms, Windows Mac Linux and it's free. SQL Developer is best suited for a big cross functional globally based team. SQL Developer is less resource intensive, compared to other IDEs. SQL Developer has the capability to manage and develop Oracle Database in both on premise and Cloud deployments. SQL Developer can also connect and interact with non oracle database like MS SQL server and MySQL etc.
Positive: Alerting features. Without this we would have to be a 24x7 shop with someone always manning the helm. With the alerting feature we can define levels of alerts and only get the most pressing alerts sent out.
ROI: OEM is free, so the ROI is whatever you make of it.
No impact on the organization's budget as Oracle SQL Developer is free.
With the increased productivity of our database administrators, they are able to better assist the software developers in prototyping future products.
Through Oracle SQL Developer, our administrators were able to normalize many of our databases, reducing the amount of redundancy, and hence increasing the performance of our main application.
