Hemiptera plant. Phloem sap, which has a higher concentration of sugars and nitrogen, is under positive pressure unlike the more dilute xylem sap. Most of the Sternorrhyncha and a number of Auchenorrhynchan groups feed on phloem. Phloem feeding is common in the Fulgoromorpha, most Cicadellidae and in the Heteroptera. The Typhlocybine Cicadellids specialize in feeding on non-vascular mesophyll tissue of leaves, which is more nutritious than the leaf epidermis. Most Heteroptera also feed on mesophyll tissue where they are more likely to encounter defensive secondary plant metabolites which often leads to the evolution of host specificity. Obligate xylem feeding is a
SAP IQ HANA which acts as an operational data store for immediate analysis. Once the data is analyzed it is integrated into SAP IQ via Near-line storage mechanisms (as described above). Here SAP IQ acts as an enterprise data warehouse that receives data from a variety of traditional sources (such as OLTP Databases and files systems), and SAP HANA Operational Data Store(ODS) When SAP IQ is used as an EDW, it can also be augmented with HANA’s in-memory technology. Common uses include planning and analysis reports where simultaneous OLTP processing is needed. In this case, data flows from SAP IQ to SAP
