Building an admin system is a requirement for most plans. But since it's not customer-facing it's not of much importance and the actions are often less complex than the customer-facing system. Often the best way to build your admin system is to use a bundle/package that provides the skeleton framework. Here we'll go over the options.

Athena - Parthenon

Might as well start with our dashboard. Athena is what Parthenon is named after, with the Parthenon temple in Athens being built to worship Athena. While working at other companies that used other Admin systems, I noticed everyone just referred to the admin system by the name of the of the bundle being used. I thought it would be cool for people to refer to asking the Goddess of Wisdom. It was built after having problems extending other dashboard systems to work with the microsystems that had been built and need to be integrated.

Athena provides the ability to add a new CRUD section within Athena by creating a new class and is able to support any data source since it's coupled to just an interface instead of abstract classes or third party bundles. Athena provides the ability to create a customisable dashboard upon login.

Pros:

Customisable Dashboard
Athena Notifications to alert employees of things
Not coupled to a data source
Professional support
Ability to be used by itself
Uses last key for pagination instead of limit
Admin to define a crud section within a single class
Ability to add extra pages

Cons:

No CSV export (yet)
Limited filter types
Not free
